Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid crystal display device, and more particularly to a driving device and a driving method for a display device, which is used for over driving (over drive) ) and so on. [Prior Art] In a conventional display device such as a liquid crystal display or the like, a plurality of gate φ lines and a plurality of source bus bars are alternately arranged, and argon is provided at each staggered point, and is formed of a plurality of halogens. A matrix-shaped display area. The display device is driven by the gate drive circuit and the source drive circuit. The gate drive circuit sequentially drives a plurality of gate lines. When driving each gate line, the source driving circuit also drives a plurality of source bus bars, and supplies the source bus bar voltage corresponding to the image to be displayed to each source bus bar. By this, the image can be displayed on the display area. In the past, based on the consideration of service life, the reversible sinus drive technology was used in the display device. A variety of different inversion driving techniques are known, and the present invention is primarily related to row inversion driving and dot inversion driving. In the column inversion driving, the polarity of the pixel voltage between each gate line is reversed. In the point inversion driving, the polarity between each gate line and each source bus line is reversed. Transfer relationship. However, a so-called over drive technique has been developed which can be used to increase the response speed of a display device. In the overdrive technology 0773-A33151TWF; KB05006 6 200847118, · For each element, an overdrive voltage is supplied to its source bus, and then the final drive voltage is supplied. The final driving voltage is the signal corresponding to the image to be displayed, which can also be called the target voltage. The overdrive voltage is set to be greater than the predetermined value of the final drive voltage. The above example can be considered as a two-stage overdrive technology that includes overdrive voltage and final drive voltage. In other examples, a three-stage overdrive technique can also be used. At this time, a pre-drive (pre-drive) voltage, an overdrive voltage (overdrive, OD for short), and a last drive (last drive) voltage are sequentially provided. The pre-drive voltage is set to be less than the overdrive voltage. In other examples of overdrive technology, the above pre-drive voltage and overdrive voltage are sequentially provided. The pre-drive voltage is set to a predetermined value smaller than the overdrive voltage. At this time, the overdrive voltage is controlled and supplied in such a manner that the required write voltage can be achieved during the write period. Thereby, the voltage of each element is the value corresponding to the image to be displayed. This technique can also be referred to as a two-stage overdrive technique. Xin In order to implement overdrive technology, it is necessary to perform multiple scans of each element during a frame. For this scanning method, sequential-scan and chase-scan can be considered. Sequential scanning is the next scan of the entire surface after each scan is completed for the entire surface. In the case of the three-stage, after the scan of the pre-drive voltage is completed, the scan of the overdrive voltage is started; after the scan of the overdrive voltage is completed, the scan of the final drive voltage is started. 0 0773-A33151TWF; KB05006 7 200847118 In the aspect of the tracking scan, the next scan is started on the way of each scan (before the scan is completed at the lowest position on the front). In the case of three stages, the scan of the overdrive voltage is started on the way of the pre-drive voltage scan, that is, after a predetermined time interval has elapsed. This time interval is equivalent to the interval of the number of predetermined scan lines. In addition, after the overdrive voltage is scanned, the predetermined time interval is delayed, and the knowledge of the final driving voltage is started. Tracking scan is a technique that can scan at 10 time intervals of offset setting data. In the following description, the complex frames in the tracking scan are referred to as sub-frames. In terms of three-stage overdrive technology, three sub-frames of pre-drive, overdrive and final drive are used. With this tracking scan, the degree of freedom of the drive interval can be increased. However, in the conventional display device using column inversion driving or dot inversion driving, when the tracking scanning scheme is used, as in the following example, the polarity inversion of the source bus bar is increased, and power consumption is increased. Will also increase. ® Figure 1 shows a schematic of an example of a three-stage overdrive technology. In Figure 1, the sequence does not change with the gate drive timing, source bus voltage waveform, and source bus polarity of the elapsed time. In Fig. 1, a line cycle time or a line period indicates a period in which the scan line is driven. Each scanning line period is a time for driving one gate line GL. As shown in Fig. 1, the tracking scan is a gate scan that performs pre-drive, over-drive, and final drive. For the example of the pattern, the time interval between pre-drive and overdrive is 3 scan lines, which is equivalent to 3 0773-A33151TWF; KB05006 8 200847118 scan line interval. Similarly, the time interval between overdrive and final drive is also the interval of three scan lines. Further, as shown, the pre-drive, overdrive, and final drive are performed during the first 1/3 period, the middle 1/3 period, and the last 1/3 of each scan line period, respectively. In the case of the above-described tracking scan, as shown in the figure, the polarity of the source bus voltage changes frequently. Specifically, there will be three polarity reversals during each scan line. For example, the polarity change in the scan line period 1 is +, -, + '. The polarity change in the scan line period 2 is -, • +, -. Such frequent polarity inversion is due to the combination of column inversion driving or dot inversion driving and tracking scanning. Referring to the polarity change below the first picture, in the column inversion driving or the dot inversion driving, the polarity of the pre-drive is reversed during each scanning line period. Similarly, the polarity of the overdrive is also reversed during each scan line. In addition, the polarity of the final drive is also reversed during each scan line period. The polarity change of the overdrive is different from the polarity change of the other two. The results resulting from this combination, as shown, have three polarity reversals during each scan line period. Such frequent polarity reversal will eventually lead to an increase in power consumption. Therefore, in the case where the tracking scan is performed in the display device of the column inversion driving or the dot inversion driving, it is necessary to be able to reduce the power consumption as much as possible. In the above description, the background of the present invention has been described in terms of the use of tracking scanning in the overdrive technique. However, the same situation occurs when a tracking scan is performed without using overdrive technology. Other examples of tracking scans are used, such as black frame insertion. In the black technology of 0773-A33151TWF; KB05006 9 200847118, when the target voltage is written, the black level voltage is written into the pixel to improve the dynamic response.

According to the present invention, when the tracking scan is performed by the column inversion driving type or the dot inversion driving type, power consumption can be reduced. ‘,,, EMBODIMENT The following is a detailed description of the present invention. However, the detailed description and the accompanying drawings are not intended to limit the invention. In other respects, the scope of the invention should be determined by the scope of the appended claims. First Embodiment Fig. 2 is a view showing the configuration of a display device of this embodiment. In the case of the example, the display device i is a liquid crystal display. The display device 1 includes a display unit 3, a gate drive circuit 5, a source drive circuit 7, and a control package path 9. The driving circuit of the present invention is included in the display device 1, and is specifically constituted by the gate driving circuit 5, the source driving circuit 7, and the control circuit 9. %

The third portion has a plurality of gate lines and a plurality of poles SB that are staggered with each other. A halogen is formed at each of the plurality of gate lines and a plurality of source U, and the plurality of elements form a display area in a matrix ='. A transistor is formed at each pixel position, and the gate electrode and the source electrode of the transistor are connected to the gate line gl and the source bus bar SB, respectively. The gate drive package 5疋 is used to drive the circuits of the plurality of gate lines in sequence. The source_circuit 7 receives the circuit of the source busbar that drives the source busbars according to the (4) image display of the 0773-A33151TWF; KB05006 15 200847118 source busbar voltage. The control circuit 9 controls the gate drive circuit 5 and the source drive circuit 7 based on the image data supplied from the CPU (Central Processing Unit) u, and displays the image on the display unit 3.

In the above configuration, when the gate driving circuit 5 supplies the pulse wave signal to drive an inter-electrode line GL, it is located in the state of the electric crystal conduction of each element on the gate line. Then, the source circuit of the source circuit is categorized by the source galvanic flow, and is supplied to each of the conductive elements through the respective source bus bars. This action is performed by the secret axis circuit 5 and the source and the drive circuit 7' sequentially on the plurality of gate lines GL under the (four) control circuit 9. Thereby, the image is displayed on the display unit 3. In the present embodiment, the display device 丨_moving device is configured to perform 歹β at == dot inversion driving. Inverted drive system: Under the control of the road, it is executed by the gate drive circuit 5 and the source box. Refer to Figure 3, in column inversion

In addition, in the dot inversion drive, for each _ line GL (per column) and each adjacent source bus SB (per row) = 5, the polarity of the source bus voltage is reversed) Point inversion drive f-transition relationship. It is not clear that in the list of the source bus SB, the neighboring gate line GL (that is, the polarity of the voltage of each row is inverted). And two: = in the detailed description, the display of this embodiment... The movable clothes are placed in a three-stage operation of the 崎 崎 料 ^ ^ ^ ^ 773 773 773 773 773 773 773 773 773 KB KB KB KB KB KB KB KB KB KB KB KB KB KB KB KB KB KB KB KB KB KB KB KB KB KB KB KB KB 9 is implemented by the gate driving circuit 5 and the source driving circuit 7. In the three-stage over-technology, each pixel is sequentially driven by a pre-driver, an overdrive (four), and a final drive (four). The final driving voltage 疋 = the signal to be displayed on the image to be displayed, which may also be referred to as the target voltage. The overdrive voltage is set to be greater than the final driving voltage, and the voltage is set to be less than the overdrive voltage.

In the above overdrive technique, each element in a kneading surface requires a secondary drive. In this embodiment, the plurality of drives are implemented in a tracking scan manner. The tracking scan is to start the F-time scan on the way of each scan. In other words, first, the pre-drive voltage is read, and the pre-drive voltage scan is delayed from the predetermined time interval to perform the scan of the overdrive voltage; and after the start of the overdrive voltage scan delay for a predetermined time interval, the final drive is performed. Voltage scanning. The predetermined time interval refers to an interval corresponding to a predetermined number of scan lines (or a tracking scan is a technique capable of shifting the plurality of frame data for a certain period of time = scanning). Here, the plurality of frames can be respectively referred to as In the two-stage overdrive technique, the pre-drive, overdrive, and final drive scans of the three sub-frames are performed. However, as shown in the example of the first figure of the background art of the present invention, when the tracking scan is performed separately The number of polarity inversions of the source bus bar is increased, and the power consumption of the inch is also increased. To avoid this, the driving device of the present embodiment controls the gate 〇773-A33151TWF according to the following manner. ;KB〇5〇〇6 17 ζυυ^47ΐΐ8 Drive circuit 5 and source drive circuit 7 This: to reduce the source busbar: drive display device i. 辏 first point, as shown in Figure 4, 11 The number of inversions. a(1)anking chest==This implementation includes vertical masking for an odd number of scan lines. Also during the complete sweep period of the & face is:: an odd multiple of the period: each scan two tear line GL Period 3 is used to sweep a random statement, as shown in Figure 4 is the period of the display area: the length of the scan area of the display area during the full sweep of a face. The number (four) scan line period is equivalent to the number of horizontal scan lines (the period of the idle line area is equivalent to the even number of lines is generally even', so the display period is the odd line period. By the full sweep. JX, the Putian line period 'so During the full scan period, the source sinks (4) odd materials. The time between 3: 2: V: shown in Fig. 5, in this embodiment, the tracking scan P: the day m mesh is in an odd number of scan lines Interval (or scan line period). JL = two in this embodiment 'in a frame and is written sequentially, between the boxes, the write voltage polarity of each element is for each sub-frame All are in a reverse relationship. ^ Driven book. The same: p" is the voltage that is driven by the voltage of the pre-drive voltage and the final voltage: "" and "-" are 〇 773-A33151TWF; KB05006 18 200847118 When driving, the source bus is in the second sub-frame between the sub-frames. Between the present embodiment, the interval between the dots in the figure is equivalent to a dry period in an odd number of scanning lines, that is, three scanning lines. As shown in Fig. 5, the household a ^ A scan line n+1 on ^-", the final drive voltage is "+". For "+", the last voltage is "~" 'overdrive voltage", and the winter drive dust is "final drive polarity." And the clock gate. Therefore, the pre-drive, over-drive and reverse are reversed. Therefore, the polarity of each element is "+" in each sub-frame voltage, and it is pre-driven on the same known line η. Drive voltage is "

In the case of the sample (four) inversion driving in the source bus bar sb, the adjacent source bus bar SB == the same chasing operation. In the case where the dot inversion driving is performed, the polarity of the adjacent cells on the source bus bar SB of the pair is inverted. In addition to the =, Π 轺 ,, the source bus SB drive principle is the same. The sergeant is kneeling down. In the same way as in Fig. 5, the present invention is mainly described with reference to the case of one source sink k row SB. In addition, when driving the display device i described above, a pixel of a pixel.反相 Inverted during pre-drive, overdrive, and final drive. This is no problem when the drive display is set to 1. Since the liquid crystal molecules respond to the absolute value of the voltage difference, even if the polarity of the voltage difference is reversed, the response of the liquid crystal blade is the same. Therefore, even if the polarity of each sub-frame is reversed, it does not cause adverse effects of the alizarin action. The present invention focuses on the characteristics of this liquid crystal molecule. Therefore, using this feature, the polarity inversion of the source busbar can be reduced without affecting the liquid crystal operation to perform the drive control described above, 0773-Α33151TWF; KB05006 19 200847118. Then, in the structure of the above-mentioned display device 1, the polarity reversal action of the source convergence = 。. Figure 6 is the end of the frame, the polarity change pattern of the middle source and the current row voltage (4). The following = the schematic diagram of Figure 6 is called ^; polarity table. $(4) Polarity® can also be referred to as Figure 6 to show two frames (昼 frame n, each segment of the frame polarity map goes to the add-on L from the raw image. During the scan line of each field. Second, the part of the f-chart is shown by the arrow, which is executed in sequence: segment == overdrive and final drive; then, the second overdrive and final drive are executed sequentially. Continue this action, ie: correct Scanning operation of a polarity map (a frame). As shown in Figure 6, because _ is a case towel, because the threshold of the full scan period of the frame is divided into countable scan lines, Between =, the vertical occlusion signal (8) is also equivalent to the odd number τ. The polarity map of the other month's 6th figure uses 4^g, the amount of S (the following, t々# uses the sweeping less than the continuous situation) In the same way, the other polarity diagrams are the same. The number of lines is different. As shown by the symbol X in Fig. 6, the sub-chamber is separated by an odd number of scanning lines, and the interval between the lines of I 3 ( In the example of the example of FIG. 5, the time interval is 5 scanning line intervals, the time interval is 3 scanning line intervals, and the 0773-A33151 TWF; KB〇5〇〇6 20 200847118 6 in the middle of the figure „interval is 5 sweeping line spacing.” Sheep 5's if the front view of the pre-ee η ^ ^ $ top drive part, starting from a frame驱动 Drive scan lines 1, 2, 3, · 邶8 (8)a ·•. Overdrive of the line 1

The pre-drive part of the mouth P-knife and the known line 6 is B-promoted by tL and 1 knife is in the same scanning line period. In this case, the time for driving each scan line by the overdrive portion is five scan lines later than the pre-drive portion.

The final part of the moving Qiu 1 and the overdrive of the scanning line 6: The hole: 疋 is performed during the same scanning line period. Thereby, the time at which each scan line is driven by the final drive is more than the overscan scan line. Another:" As shown in the figure in Fig. 6, between the plurality of sub-frames constituting a frame and being sequentially inserted, the polarity of each pixel is in each sub-rotation: taking scan line 1 as an example, during pre-drive 'Scan line 1, Dan, ", 疋 is driven by +". When overdrive, the pixel of scan line 1 is driven by -". In addition, in the final drive, the scan and line are driven by "+". The other scan lines are also identical in each sub-frame. In addition to the magic position, in addition to this, since the column inversion drive or the dot inversion drive is used, the polarity of the upper and lower cells is inverted. In addition, the polarity of each 也是 is also inversely related to each frame. Therefore, in the frame ^, the polarity of the square and the halogen in the pre-drive, overdrive, and final drive is "+, -, +". At this time, in the frame n+1, the same pixel is driven, Overdrive and finally, the pole (4) in _ is "_, +, -". In the present embodiment, the display device is driven in the above manner, its 0773-A33151TWF; KB05006 21 200847118 results are as shown in the figure, and the polarity is the same. In the case of the 士 々 ▼ during the field line 'the number of source bus SB. ^Reducing the polarity inversion of the source bus bar SB. The second figure shows that the seventh picture is a schematic diagram of the operation of the display device 1 with the conventional device. The operation of the display device 1.

Each scan line period is driven as in the case where the gate drive timing is pre-driven, overdriven, and the most is not. The tracking scan is performed at intervals of 3 scans of the continuation gate. P- 5 Seto Putian Although the sample neutron frame of Figure 6 is shown in Figure 7: a scan line interval, but for easy understanding, Figure 2::Γ0!:: is separated by 3 scan lines). In addition, if the line period is the most profitable, each scan is carried out during the period of (I), 3, and 3: The timing of the above tracking scans for 4 and 1/3 periods is the same as in Fig. 7 of the conventional example. Autumn; 1 picture and the actual can be found, in the conventional technology, the picture = the power _ polarity has three slaves, and in the real _, = the source line during the description line is difficult Sex remains the same. This difference is achieved by the polarity reversal of the source bus bar 〇 773-A3315lTWF; KB05006 22 200847118 between the above sub-frames. For the "― 〇 x dance ^ field line 1, the pre-driver is a sentence, and the attack is driven to the factory.

|, Overdrive η +"° In the scan line 2, the pre-drive is "one", and the polarity is reversed and the drive is "-". This - source sink of each source bus: factory, as shown in Figure 7, the polarity of the L-row voltage remains constant during each scan line. 8 is a diagram of the second embodiment of the present invention and the prior art. In the middle, *敕 = the polarity map of the conventional technique of the graph. During this prior art period, it is equal to an odd number of scanning line periods (the time interval between the 13 scanning line frames is also an odd number of scanning line intervals (5 scanning line intervals). 7 1 (four) green ^,, this The difference between the embodiment and the prior art is that the polarity between the frames of the technique is not reversed. In the frame n, the scan line 1 scans:; the "+"' overdrive is "+" and the final drive is "+". The pre-drive of the factory is "one", the overdrive is "one", and the final drive is. The result is shown in Figure 8®. During each scan line, the polarity of the source sink voltage is reversed three times. In contrast, the present invention does not substantially reduce the number of polarity inversions of the source busbar voltage as shown in Fig. 6. Further, as explained below, the advantage of this embodiment is that it can improve the improvement of the dome. Fig. 9 is a diagram showing the polarity of the other modes. The time interval between the sub-frames in Fig. 9 is an odd number of scanning line intervals, which is the same as that of the embodiment of Fig. 6. In addition, as in the present embodiment, each sub-picture The polarity between the frames is reversed. The difference in the example is that the masking period in Fig. 9 is an even number of scanning lines, and the full scanning period of one frame is also overdriven to 0773-A33151TWF; KB05006 23 200847118 line], the result is as shown in the figure In the first 5 scans 1 to 5), the polarity of the overdrive and final drive is different, and the polarity of the pre-drive is different. During the next 5 scan lines (from the 10th), the pre-drive and over-drive are the same polarity, but different from the most-driven. Therefore, the pattern of polarity has changed on the way. Discontinuities and inconsistencies can lead to deterioration of enamel. in

In t j , since the polarity pattern is the same on all the scanning lines, the pattern is fined, and the quality is deteriorated. The present invention is described in the first embodiment of the present invention. In the display device driving device as described above, the "gate driver and the source: force" performs column inversion driving or dot inversion driving on the display device, and the manner in which the plurality of sub-frames are offset by a predetermined time interval in the square frame Perform a tracking scan at the end. Because of this, the driving device of the present invention is: a gate driver and a source driver. The control method is to set an odd number of '5' sub-frames to an odd number during a full scan containing the vertical blanking signal; and to track the polarities of the elements in the complex t-frames during the scanning time. As described in the sub-frame H, in the present invention, ()) is set to an odd number of sweeps during a complete scan = a full scan, and the number of bins is odd (in the above example; The sequence is written in the complex sub-frame = =; the frame is inverted between the frames. By this structure, during the selection of the interpolated line 0773-A33151TWF; ICB05006 24 200847118 source bus is sequentially sent separately Corresponding to the plurality of source bus signals of the plurality of sub-frames, the plurality of source bus signals are respectively supplied to the complex scan lines (complex elements) of the offset tracking scan interval. Therefore, in the present invention, The voltage polarity of the plurality of source busbar signals is the same during one sweep "line period, so that the number of times of inversion of the source busbar voltage is reduced, thereby reducing power consumption. And in this embodiment, the source busbar signals are common to each other. (__) voltage signal Since the number of polarity inversions can be reduced, it is possible to reduce the source (4) and the common money generating circuit. In addition, since the inversion pattern of the polarity inversion of the source bus and the common signal maintains continuity (consistency), it is possible to avoid 昼The deterioration of the quality results in better image quality. Second Embodiment The second embodiment of the present invention will be described next. The following mainly describes the differences between the disci and the embodiment, and the phase is omitted from the first embodiment. In the present embodiment, the device and its drive are the same as the first embodiment, and reference may be made to Fig. 2. In addition, the first example and the second embodiment are the same at the same time. (4) Column inversion drive or dot inversion drive. Perform three-stage overdrive in tracking mode - a full scan period containing vertical blanking signals is equal to several scan line periods. The difference between the example and the second embodiment lies in the fact that the interval between sub-frames in an embodiment is equal to an odd number of scan lines, 0773-A3315 IT WF; KB05006 25 200847118 == also in the second embodiment ___ = two = first real In the example, between the number of sub-frames that constitute the frame and are sequentially inserted, the turns are in an inverse relationship. However, in the second embodiment;:, the first: the sub-frames are sequentially written. Between the complex sub-frames, the sub-frames are sub-inverted. The polarity of the D sub-frames is not shown in Figure 10 as the parent map of this embodiment. If ΘΚ does not correspond to the polarity of the alpha map, In the present embodiment, an even number of scan line intervals, and the interval between the body 1 θ "-__ is .. π 2 /, the version is also 疋 4 scan lines. In addition, the same frame The polarity of gravity and f, I, field, and, in the pre-drive, scan line 1, the pre-drive is "+ m brother after the frame η line period" is "+ ^" overdrive (in 4 scans) Also "+". The same / ‘take... drive (after 4 scan line periods) 丄: For scan line 2, the pre-drive is “-”, the force is “-”, and the final drive is also “―”. In the example of the 10th figure, the SB has the same polarity. The number of times the source bus is reversed due to the σ line. This σ reduces the polarity of the source bus bar SB as described above. In the present invention, the hearing device is implemented in a four-fourth embodiment, and the display device is formed, and in the form of a self-inhibition or point-inversion driving method. The interval between the two sub-frames is set to be timed, and (1) is in the face: field. Therefore, the driving device of the present invention is set to an odd number of sweeps t = vertical 遽The complete scan period of no signal /, 扃, (2) the number of sub-frames is odd; (3) 0773^3151TWF; KB05006 26 200847118 The time interval of scanning is equal to the even number of scan line intervals; (4) constitutes once the box and The sequence is written in the child's gold box and the number of the elements in the box is in the second ring. By this structure, the complex source bus signal and the pad polarity are during one scan line. The number of inversions of the same two-row voltage is reduced, which in turn can reduce power consumption. It can also maintain the consistency (consistency) of the service as described in the first embodiment, so that the sub-ization of the book quality can be avoided. Good enamel. j Your brother, Dan, the second child of the evil brother The following is mainly for the sake of explanation, and the same matters as those of the first embodiment. Next, the difference of the first embodiment of the present invention will be omitted.

The overall configuration of the first embodiment and the driving device and the second embodiment are referred to. In addition, the first implementation or the dot inversion drive. the same. That is, the column inversion driving period is used for odd-numbered sweeps;::: including vertical coffee implementations instead of: three embodiments are not used ^ In the third embodiment, the following uses:: two-stage overdrive, relative In other words, each element is driven by two drivers: two-stage overdrive. Drive the electric dust to drive. %^ is driven, and then finally. In addition, in the first #/,, 贝也, the time interval between sub-frames is equal to 0773-A33151TWF; KB05006 27 200847118. However, in the third embodiment, the lines between the sub-frames are evenly spaced or evenly scanned: the sub-book is in the ::::: relationship. In contrast, the polarity of the two subsexually written sub-frames in the sub-frames is inconsistent. The display device of the present embodiment and the 苴 苴 和 and the 12th θ / can satisfy the above conditions, the eleventh figure can be applied to the polar map. Regardless of either of these two polarity maps, in Figure 11, the full scan period is equal to an odd number: two 1: line). The number of sub-frames is even (including overdrive and most, , and both). Tracking scan (overdrive and finally, when the condition is 'when the scan line is driven by the final _, the broom is driven by the overdrive. The last 玖 ^ \ '0 with the same frame - the polarity of the scan line' has passed Drive and take, and drive the same (non-inverted). For example, for the sweep of the frame η, the overdrive is "+", and the final drive (4 scan lines, after) is also +". Similarly, for scan line 2, the overdrive is -", and the final drive is also "-". In the example of Fig. 11, the polarity of the source bus SB is the same during each scan line. Therefore, the 0723-A33151TWF of the source busbar can be reduced; KB05006 28 200847118 The number of polarity reversals. In Figure 12, the time interval between sub-frames is an odd scan line interval, specifically 5 scans. Line spacing. For example, when scan line 1 is scanned with the final drive, scan line 6 is scanned with overdrive. In addition, the polarity of the same scan line in the same frame is the same in overdrive and final drive ( Non-reverse). For example, the scan line 1 of the frame η Say, the overdrive is "+", and the final drive (after 5 scan lines) is also "+". Similarly, for scan line 2, the overdrive is "-" and the final drive is also "-". As seen from the example in Fig. 12, the polarity of the source bus bar SB is reversed during each scan line. However, the polarity of the second half of each scan line period is the same as the polarity of the first half of the next scan line period. The number of polarity inversions can be suppressed to the same extent as the example of Fig. 11. As described above, in the third embodiment of the present invention, the driving device of the display device is driven by column inversion driving or dot inversion driving. The method is constructed, and the tracking scan is performed by shifting between the plurality of sub-frames in a frame, and the timing is intermittent. Therefore, in the driving device of the present invention, (1) is included in one side The full scan period of the vertical blanking signal is set to an odd number of scan lines; (2) the number of sub-frames is even (two stages in the above example); (3) the time interval of the tracking scan is equal to an odd or even number of scans Line spacing (4) The polarities of the elements in the complex sub-frames that form a frame and are sequentially written are not inverted between the sub-frames. By this structure, the complex source bus signals are The voltage polarity is the same during one scan line, so that the number of inversions of the source bus bar voltage is reduced by 0773-A33151TWF; ICB05006 29 200847118 is low', and thus power consumption can be reduced. And in this embodiment, the first embodiment can also be maintained. Said: the reverse pattern continuity ("sense", so it can avoid the deterioration of the quality of the enamel, resulting in better enamel. In addition, in this implementation is the use of two-stage overdrive technology, "overdrive The voltage and the final drive voltage are sent to the respective elements. In the other::丨: The pre-drive voltage and overdrive voltage can also be sent sequentially. The letter of the letter. The pre-drive voltage is set to be less than the overdrive voltage. The four-pass overdrive voltage is controlled in such a way that the write-in time can be reached within the write time. In this way, each element pays the value of the displayed image (less than ^, which is also the same in the example). This point is the fourth in the following.

FOURTH EMBODIMENT Next, the differences in the third embodiment of the present invention will be omitted. Fourth embodiment. The following is mainly for the same as the first and third embodiments, and in the present embodiment, the factory is the same as the first embodiment, and the overall structure of the device and its driving device is not ▲ And the fourth embodiment is in the second item. In addition, the third embodiment is driven by a motion or a dot inversion. One Kui is the same. That is, the column inversion driving period is equal to an odd number of sweeps; the full sweep segment including the vertical blanking signal is overdriven. Sub-frame /, 3. Use the tracking scan to perform two-order time intervals of any value, regardless of the even number °773-A33151TWF; KB〇5〇〇6 30 200847118 Scan line interval or odd scan line interval. The second embodiment differs from the fourth embodiment in that the third sub-target example forms a frame and is sequentially written by the plurality of sub-frames = each pixel polarity in each sub-昼The boxes are not reversed. In contrast, in the fourth and second examples, the two components are framed and the second plurality of sub-frames are sequentially written, and the polarities of the elements are inversely related between the sub-frames. In the fourth example, the polarity of each sub-frame between consecutive individual frames is not reversed, that is, between the last sub-frame of the frame and the first sub-frame of the sub-frame. The polarities of the pixels are not reversed. The present invention and the driving device thereof satisfy the above-mentioned article: '. In order to satisfy the above conditions, the two polar patterns shown in Fig. 13 and Fig. 14 can be applied. Either the test of the (4) polarity chart can be applied. The ^13 picture is the same as the U picture. The 'full scan period is equal to the odd number field period (13 scan lines). The sub-book frame is overdriven and the most line is moving. Λ, 6 to 0 is an even number (including take, ,,, and drive). Tracking scan (overdrive and interval are even number of lines, coffee ^ in a f:: 13 picture is different from the 11th picture The point is that in the ηth picture, the ground is in the U picture, which constitutes a picture frame over the _:= gate (that is, it constitutes a check between Xitian, - Η, , , .夂 辛 辛 取 取 取 取 取 取 取 取 取 取 取 取 取 取 取 取 取 取 取 取 取 取 取 取 取 取 取 取 取 取 取 邀 邀 邀 邀 邀 邀 邀Between the drivers (ie, the last written 73~Α33 151 TWF; the sub-frame of Kb〇5〇〇6 31 200847118 and the sub-frame originally written by the next frame), the polarity of each element Specifically, in the scan line 1 of the frame n, the polarity of the overdrive is "+" and the polarity of the final drive is "-". In the frame n+1, the polarity of the overdrive is "_". The polarity of the final drive is "+". Therefore, the polarity is maintained and not reversed between the final drive of the frame η and the overdrive of the frame n+1. 曰曰In this way, although in Fig. 13, The polarity of the sub-frames is reversed, and the polarity of the 疋 疋 维持 维持 维持 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 The above description explains the polarity diagram of Fig. 13. The example of Fig. 13 is the same as the case of Fig. 12, that is, the polarity of the second half of each scanning line is the same as the polarity of the first scanning line _ the first half. The number of polarity reversals can be suppressed to the same extent as the examples in U and 12. ^ , 14 can be regarded as the deformation of Figure 12. For example, the time interval between the sub-frames of the same figure as in Fig. 12 is an odd number of scanning line intervals, specifically five scanning line intervals. The same as in the eleventh figure, the above-mentioned "++" The —— , , , , , , , , , , , , , , , , , , , , , , , 构成 构成 构成 构成 构成 构成 构成 , , , , , , , , , , , , , , , , , The style of one by one. Therefore, although the polarity between the sub-frames between the sub-frames that constitute a frame 5 will be reversed, the final drive of the frame will be checked (ie, a frame). The polarity is maintained unchanged between the last written sub-frame and the over-drive of the person (ie, the sub-frame that was originally written in the next frame). 0773-A33151TWF; KB05006 32 200847118 In the case of the extreme output row, the source =1 remains the same during each scan line. Therefore, the example of Fig. 14 can also be called the number of polarity inversions of the low source bus SB. In the fourth embodiment of the present invention, the display device performs a column inversion driving or a dot inversion driving method, and the plurality of hand frames are scanned in a frame. . Therefore, the front door of the present invention has a full scan period of two vertical shading signals: ί: during the line drawing; (2) the number of sub-frames is even (the above-mentioned even scan line interval (any tone). The two 'doors, b, (4) form a frame and are sequentially 窎 = the polarity of each element in the frame of the sub-frame, which will be reversed between the sub-frames and finally written in the - frame In the sub-frame and the next frame, the polarity of each element is not reversed. With this structure, the number of inversions of the pole bus voltage is reduced, thereby reducing the sum of the electric power. In this case, Maintaining the preferred embodiment as shown in the first embodiment, (4) avoiding the image quality, such as *, to the fourth embodiment, the present invention can be applied to overdrive. It is used in overdrive technology. The drive device that uses the display is driven by column inversion drive or dot inversion drive, and the scan scanner is used. The invention can be applied. For example, for other purposes of preparing for the drive. In the case of tracking scanning, the present invention is also 0773-A33151TWF; KB05006 33 200847118 = suitable for use Other examples of tracking sweeping, such as black insertion technology. In the factory black technology, 'when the target voltage is written, the black level is written into the halogen to improve the dynamic response. The invention is not limited to the driving technology. This point is the same in the following other embodiments. The structure of the gate drive can be applied to the structure of the drive circuit 5 for driving the display device of the present embodiment. For the gate drive circuit, the following are separately tested. =) ^ut block control case; (7) case where block control is not executed = (1) Example of performing block control In the example shown in Fig. 15 of the month, the gate drive circuit $ is composed of a plurality of gate drive regions In the 15th figure, the block is a 1C chip. Each gate drive block is used to drive a block containing a plurality of interrogation lines. In Figure 15, three blocks A, B, c, and three CC chips are labeled. The two blocks A, B, and c share the start pulse. The start pulse STV is the trigger pulse that starts scanning, from the control circuit to blocks A, B, and C. In addition, between the blocks is used to maintain the operation; The lines are connected. On the other hand, the enabling signals of the three blocks A, B, and C are different. As shown, the three blocks A, B, and C receive different gates from the control circuit. Signals GOE1, GOE2, GOE3, thereby enabling the enabling control of the individual blocks. The number of scan lines of each block is set equal to the tracking scan interval 0773-A33151TWF; KB05006 34 200847118 If the tracking interval is _ The number of lines of the _j £ block is also n. As shown in the above example, in the present invention, the gate drive circuit $ is composed of a dynamic drive block, and each gate drive block is used to drive The plurality of gate drive blocks are individually enabled to enable the enabling control of the individual gate drive blocks. ', in the present invention, the boundary of the gate driving block is scanned by the last sub-frame, except for the last sub-frame: :::f and more than one block boundary respectively ^ ^^ . ^ ± U In the example of the U, the number of scanning lines of each block is divided by the number of scanning lines, whereby the number of scanning lines of the β-band W in the idle driving area is set to be the boundary of the above requirements. J is full. The setting of the above boundary is explained in detail below. In the case of the tracking scan, when the most = hard number of sub-frames, the 圭 取 的 的 取 取 开始 开始 开始 开始 , , , , , , , , 其他 其他 其他 其他 其他 其他 其他 其他 其他 其他 其他 其他 其他 其他 其他 其他 其他 其他 其他 其他 其他As described above, the block boundary is the same as the scanning position of one or more sub-frames other than the last sub-frame when the reading is composed of one or two readings, and the boundary is the same. 3, the block boundary is when the initial scan line is taken in the last sub-frame to scan the boundary of the scan line in 1 - the way = = = = the field line and its previous capture, i-style . For example, in a two-stage display device, the time interval is "solid scan line interval. The boundary is set to the nth scan line and the state strip scan line 0773-Α33151TWF; between KB05006 35 200847118. In addition, in three stages In the case of the block, the block boundary is set between the 2nd scan line and the 2n+l scan line. Further, the scope of application of the present invention can satisfy the above requirements (ie, when forming the last sub-picture of a frame) When the frame starts scanning, if the scanning position of more than one sub-frame other than the last sub-frame is consistent with more than one block boundary, the position of other block boundaries is not limited. It can also be designed into multiple blocks. For example, the number of scanning lines of each block can also be set to half, and each block is further divided into two pieces, which can also be regarded as a modification of the 15th drawing. Fig. 16 shows the gate driving circuit Other structural examples. In this example, the gate driving circuit can be formed on the glass substrate together with the display portion, for example, a low temperature poly-silicon (LTPS) circuit formed on the glass substrate. Or an amorphous silicon (a_Si) circuit, and the gate driving circuit may also be a single-chip integrated circuit. The gate driving circuit is composed of a plurality of functional blocks, each functional block has a fifteenth The figure drives the same gate drive block function of 1C. Figure 17 shows an example of the operation when the above block control is executed. The start pulse wave STV and the gate control clock GLK are common to all blocks A, B, and C. The pulse signals P are generated corresponding to the signals STV and GLV. Then, in each block, the pulse wave P is synthesized with the gate enable signal, and as a result, the scanning lines are driven in the oblique line portion of each pulse wave P as shown in the figure. As shown in the figure, the gate enable messages GOE1, GOE2, and GOE3 respectively supplied to the blocks A, B, and C are shifted from each other. Therefore, it is possible to shift the drive timing between the blocks by the 0773-A33151TWF; KB05006 36 200847118 , according to - drive and final drive tracking sweep. Line pre-drive, after the 18th figure shows the implementation of block control. Example. In this example is also the preparation _ F, /, his operation can therefore be properly implemented Follow the order; pre: dynamic tracking sweep . Donghugongzhong drive

Further, in the example of Fig. 18, during the first 1/3 of the period of the block Α 3, all of the pre-drive-scan-line driving is performed. Similarly, block B performs all three drives during the individual, overdrive, and final periods. In addition, all three kinds of driving are performed in the last 1/3 period of the block wH3 line drawing period. As in the above-mentioned speed, in this embodiment, the gate is driven to move the block, and each of the idle driving blocks is used for driving;; = ^ The line of the direct drive block is controlled by an individual enable signal 1. It is: the boundary of the human 'gate driving block is the scanning position of more than one sub-frame except the last sub-frame and more than one block boundary when the scanning is started. Set them consistently. 8. Therefore, in the present embodiment, the two-block boundary can be appropriately set in the case where the tracking scan is performed by the block control, whereby when the last sub-frame constituting a frame starts scanning, the other sub-frames are displayed. The scan position and the precedence position boundary are respectively. With this structure, each block can be controlled by an enable signal. 0773-A33151TWF; ICB05006 37 200847118 (2) Case where block control is not performed Next, the case where the enable control of each block is not performed in the above-described gate drive block will be described. The brother 19 shows an example of the structure of the gateless drive circuit 5. In the example of Figure 19, the gate lines are divided into three groups A, B, and C. All gate lines of groups A, B, and C are controlled by a gate drive circuit. The gate drive circuit can also be a 1C chip. Further, the gate driving circuit may be a circuit such as LTPS or a-Si formed on the glass. The gate drive circuit uses the start pulse wave STV input from the control circuit and the gate enable signals GOE1, GOE2, GOE3 to drive the groups A, B, and 〇 in the above embodiment, each of which uses a The energy signal, this block control is not used in the structure of Figure 19. In Fig. 19, one gate drive circuit uses all enable signals GOE1, GOE2, and GOE3 to drive all groups a, B, and C (each group is driven by using all enable signals). . In order to perform the present embodiment, it is preferable to set the number of gate enable phases to be larger than the number of sub-frames. Specifically, when the three-stage overdrive is performed, the number of sub-frames is three, and the number of gate-enable phases is set to three or more. In addition, in the present embodiment, the insertion phase between the sub-frames is arranged at different enable phases for each time interval. For example, when the insertion phase at the beginning of a time interval is configured in one gate enable phase, the insertion phase at the beginning of the next time interval is placed in the other gate enable phase, and the next insertion phase is also placed in Other gates 0773-A33151TWF; KB05006 38 200847118 Extreme phase. Further, in the case of the present embodiment, the gate-driving circuit is constituted by a repetitive combination of η-phase circuits using control signals of at least two phases or more. Therefore, the entire circuit is preferably set to an integral multiple of the repeating circuit. Further, in the present embodiment, the unit of the repeating circuit is preferably set to an odd scanning line. In particular, in the present embodiment, the full scan period including vertical masking is equal to an odd number of scan lines. In order to match the full scanning period equal to the odd-numbered strips of 10 scanning lines, a structure having one unit of repeating circuit equal to an odd number of scanning lines is required. Fig. 20 and Fig. 21 are timing charts showing an example of the operation of the display device. In this example, the number of gate lines of each group is "3η+2" (η is a positive integer). Figure 20 shows the enable signals GOE1, GOE2, GOE3 of each group and the enable signals GOE1, GOE2, GOE3 synthesized by the three groups. The enable signals GOE1, 10GOE2, GOE3 synthesized in the figure are supplied from the control signal to the gate driving circuit (1C wafer of Fig. 19). As shown in Fig. 20, the composite enable signals GOE1, GOE2, and GOE3 are assigned to drive groups A, Β, and C. In Fig. 20, the time intervals 1, 2, and 3 are equivalent to the time interval of the tracking scan. At the beginning of time interval 1, the pulse of the enable signal GOE1 is set. Therefore, the insertion phase of the 'in time interval 1' sub-frame is assigned to the enable signal GOE1. Similarly, in time interval 2, the insertion phase of the sub-frame is configured to enable signal GOE3. In addition, in the time interval 3 0773-A33151TWF; KB05006 39 200847118, the insertion phase of the sub-frame is configured to the enable signal GOE2. Therefore, in Fig. 20, the insertion phase between the sub-frames is assigned to different enable phases in each time interval. As a result, as shown in Fig. 21, the pre-drive, overdrive, and final drive sub-frames can be scanned in a time-interval manner to realize tracking scanning. Fig. 22 shows another operation example of the display device. In this example, each group scan line corresponds to the case of "3n + 1" (η is a positive integer). In this example, the insertion phase between sub-frames is also assigned to different enable phases in each time interval _. Therefore, as shown in Fig. 21, tracking scanning of three sub-frames can be realized. As described above, in the present embodiment, the tracking scan can be realized even if the enabling control of each block is not performed. It can fix the time interval phase corresponding to the repeating circuit, increase the degree of freedom in timing design, and select the most suitable timing from the enamel angle. In addition, it maintains the continuity of the source bus and common signals, avoiding the reduction of enamel. Further, the embodiment is a display device having a driving device. 10 The invention does not limit the type of drive device. Other examples of the invention may be like a display device. Further, another example of the present invention may be an electronic device having the display device of the above-described driving device. The electronic device can be any of a mobile phone, a personal digital assistant (PD A), a notebook computer, a car navigation device, a television, a digital camera, and a liquid crystal display device.

Any one skilled in the art can avoid the spirit of the present invention without departing from the spirit of the present invention. When attached, ^Hr^ is attached, so it is accurate.
