Description

1291150 IX. Description of the Invention: [Technical Field of the Invention] The present invention relates to a liquid crystal display, and more particularly to a driving method capable of improving display quality. [Prior Art] Please refer to Fig. 1, which is a schematic diagram of a conventional flip pixel matrix. In the i-th figure, a 3x3 flip pixei array i 〇〇 is taken as an example. The flip-flop matrix 102 includes four data lines 102(1) to 102(4), three scanning lines 104(丨)~1〇4(3), and nine pixels 106. Each pixel 1〇6 includes a thin film transistor 20 and a pixel electrode (pixei eiectr〇de) 22. When the flip pixel matrix 100 is driven in a column inversion mode, the scan signals on the scan lines 104(1) to 104(3) sequentially turn on the thin film transistors 20 in the columns of pixels 106, and As shown in the figure, the data lines 102(1) to 1〇2(4) transmit the corresponding pixel voltages to the corresponding pixels 106 in the driving order of the positive and negative polarities in the mother-picture time. Therefore, as shown in Fig. 1, the pixel voltage on each of the pixel electrodes 22 and the pixel voltage on the pixel electrodes 22 adjacent thereto are opposite to each other to achieve dot inversion (dot). Inversion) The written quality of the pattern. After one screen time, the pixel element 6 which was driven by the positive polarity was driven by the negative polarity, and the halogen element 1〇6 which was originally driven by the negative polarity was driven by the positive polarity. However, when the flip pixel matrix 100 is driven in the row inversion mode, a serious cross talk phenomenon occurs. Taking the first data line 102(1) and the pixel electrode 22 of the book 106(1) as an example, a transverse electric field E will be formed between the data line 102(1) and the pixel electrode 22. The reason for this transverse electric field e is the voltage difference between the pixel electrode 22 and the data line 1 〇 2 (1). This transverse electric field will affect the alignment of the original liquid crystal, causing light leakage. This kind of light leakage is caused by different degrees of influence on each column of pixels, so that the brightness of the entire picture • looks uneven, and there are bright and dark interlaced fine lines. Light and dark interlaced fine lines will seriously affect the quality of the displayed image. The traditional solution is to increase the distance between the data line 1〇6 and the halogen electrode 22 to reduce the effect of the transverse electric field on the liquid crystal molecules, but this method will reduce the aperture ratio of the pixel 1〇6. Therefore, solving the problem caused by the crosstalk phenomenon driven by the line inversion mode is still an urgent problem to be solved in the industry. SUMMARY OF THE INVENTION In view of the above, an object of the present invention is to provide a liquid crystal display and a driving method thereof, which allow adjacent pixels in each column to be more evenly affected by crosstalk (to improve the overall). Display the quality of the picture. According to an object of the present invention, a driving method of a liquid crystal display is proposed. Liquid crystal displays include a pixel array. The pixel array is a fUp pixel array. The driving method of this liquid crystal display is as follows. The anilin array is driven for the first time so that each pixel in the pixel array has a pixel voltage of opposite polarity to the upper and lower left and right pixels. Then, in a second time, the thin film electro-crystal system coupled to the scan line in the pixel array is turned off, and the data driving circuit outputs the first voltage to the data line and the output connected by the pixel driven by the positive polarity. The second voltage is connected to the data line connected to the pixel driven by the negative polarity. Wherein, a picture time includes the first time and the second time. According to another object of the present invention, a driving method of a liquid crystal display is provided which comprises a pixel array. The pixel array has n rows of pixels and is electrically connected to the scan lines and the +1 data lines. The adjacent two columns of pixels in the pixel array are electrically connected to the first to third data lines and the second to the N+1th TW1948PA 6 1291150 data lines, respectively. The driving method of this liquid crystal display is as follows. In a first time _ interval, sequentially scanning from the first scan line to the scan line, and driving the pixel array by N+1 data lines to make each element in the pixel array 9 pixels adjacent to the top, bottom, left and right have pixel voltages of opposite polarities. Then, in a second time, the thin film electro-crystal system coupled to the scan line of the pixel array is turned off, and the first voltage is supplied to the data line connected by the pixel driven by the positive polarity and the second is provided. The voltage is connected to the data line connected to the element driven by the negative polarity. Wherein, a picture time includes a first time and a second time. According to still another object of the present invention, a liquid crystal display is proposed. The liquid crystal display includes a pixel array, a scan line and a Ν1 data line, and μ and Ν are positive integers. The pixel array has a plurality of pixels and is electrically connected to the scan line and the N+1 data lines. The adjacent two columns of pixels in the pixel array are electrically connected to the i-th to N-th data lines and the second to N+1th data lines, respectively. The data driving circuit is electrically connected to the pixel array via the N+1 data lines, and is configured to output the first voltage and the second voltage. The scan driving circuit is electrically connected to the pixel array via M scan lines and is used to output a scan signal. In the first time, the scan driving circuit sequentially scans from the first scanning line to the Mth scanning line, and the data driving circuit drives the pixel array via the N+1 data lines to make the pixel array Each pixel has a pixel voltage of opposite polarity to the pixels adjacent to the top, bottom, left, and right. In the second time, the scan driving circuit cuts off the thin film electro-crystal system coupled to the scan line in the pixel array, and receives the first voltage to the negative voltage by the data line connected to the positively driven pixel. The data line connected to the sexually driven element receives the second voltage. The above described objects, features, and advantages of the present invention will become more apparent and understood.

TW1948PA 7 1291150 [Embodiment] The reason for causing dull lines is the voltage difference between two adjacent data lines and the pixel electrodes. The transverse electric field caused by this voltage difference affects the predetermined alignment direction of the liquid crystal molecules. The image of the present. And the leakage phenomenon of each column of pixels is affected by the transverse electric field of different magnitudes with the equivalent voltage on the data line, so that the displayed picture will have bright and dark lines. Please refer to FIG. 2, which is a schematic diagram of an example of a pixel array. The pixel array 200 has a row of N rows and a total of M*N pixels p. N and M are positive integers. The pixel array 200 is electrically connected to the scan lines S(1) to S(M) and the N+1 data lines D(1) to D(N+1). And the N-picture pixel voltage of the first array of pixels is respectively transmitted by the corresponding 2nd to N+1th data lines, and χ is a positive integer and ‘M-1. The voltages of the X+1th column pixel u are respectively transmitted by the corresponding i-th to Nth data lines. For example, the pixel array 2 is a rp pixel array of two rows (R1 to R20) of 35 rows (C1 to C35) and is shown in Fig. 2. The pixel array 2 is electrically connected to the scan lines s〇)~s(2〇) and the data lines D(l) to D(36). Taking χ==2 as an example, it means that the pentaline voltages of the second column of pixels are respectively transmitted by the corresponding second to 36th data lines d(2)~d(36), and the following pictures are drawn. The 35-character voltage of the third column of pixels is transmitted by the corresponding first to 35th data lines d(1) to D(35).

Please refer to Figures 3A and 3B. Fig. 3A is a diagram showing the magnitude of the voltage of the pixel stored in each pixel p in the first picture F1. Fig. 3B is a diagram showing the magnitude of the voltage of the pixel stored in each pixel p in the second picture F2. The pixel array 200 is driven by the line inversion (c〇lumninversi〇n) mode and the % gray scale value is taken as an example, and the first and second screens F1 and the second screen F2 are displayed. The positive and negative polarities corresponding to the 5〇% grayscale values are shown. The pixel voltage of the sex is, for example, +6·6 and +2·〇V. And when the first surface F1 is displayed, the positive pixel voltage is driven first and the odd data lines are TW1948PA 1291150

D(l), D(3). "D(35) electrically connected to the element P, and driven by the negative pixel voltage and even data lines D(2), D(4)...D (36) The pixel p of the electrical connection. After the first picture F1 is displayed, the voltage value of the pixel voltage stored in each pixel P is as shown in FIG. 3A, for example, the first in FIG. 3A. The value listed in the first row ci of the column ri, 6·6, represents the voltage value of the pixel voltage received by the pixel ρ(ι, 丨) in Fig. 2. Then, due to the column inversion In the driving mode, after the second screen F2 is displayed, the pixel voltage stored in each pixel p is as listed in FIG. 3B, and the elemental p which is driven by the positive polarity is driven by the negative polarity, and the negative is originally used. The sex-driven pixel P is driven by the positive polarity. Next, please refer to Fig. 4, which shows that each pixel p has a corresponding data line in the time when the pixel voltage is maintained for each pixel D. The equivalent voltage rms value of the upper voltage change (the equivalent voltage rms value is generally referred to as the equivalent voltage value). For example, in Figure 4, the value indicated by the third row of the third column is 6.3 volts, representing 6.3 volts. Etc The voltage rms value. That is to say, this 6.3 volt represents the equivalent voltage rms value of the voltage change on the data line when the pixel Ρ(3,3) maintains the pixel voltage of 6·6 volts. Referring to the 帛3A map and the 3β map, the data line D3± voltage seen from the pixel P(3,3) is maintained at volts for 17 cycles (one cycle represents the input voltage of a column of pixels). The required time is). Therefore, the period of 17 is the time when the pixel voltage is input to the fourth column to the second column, and then the pixel is displayed when the second screen F2 is displayed, and 3) the data is felt. The voltage on line D3 becomes 2 volts and is maintained for 2 cycles. Thus, the equivalent voltage history of the pixel voltage on the data line D3 seen by the pixel 3) is UUxm 八 2)/19} reopening the root number, ie The value indicated in the third row of the third column is 6.3. The pressure of the pixel is not changed after the screen is maintained for one screen time. The parental electrode and corresponding data are replaced.

The voltage on line D will have a change in time. Yu Yu Xue Luan Lan 》 w廿人咖 Produce a check to the electric field E is proportional to this voltage difference. This transverse electric field E causes a so-called image. Therefore, by means of Fig. 4 and Fig. 3A and Fig. B, it can be known that the talk F1 to the second face F2 is in the period of 'the member's picture electrode and the neighbor's pixel electrode. The voltage difference between D changes, and the result is plotted in the 5th _ 1 (four) gamma diagram, which lists the voltage difference between the pixel electrode of each pixel and the data ❹. As shown in the figure, each number represents the voltage difference between the 黾 黾 之 HI HI 与 与 与 与 与 与 与 对应 对应 与 与 ( ( ( ( ( ( ( ( ( ( ( ( ( 去 去 去 去 去 去 去 去 去 去 去 去 去After the value). For convenience of description, four pixels P(1,3), ρ(ι,4) p(2,4) are illustrated, and a schematic structural diagram is shown on the sixth figure.

Please refer to FIG. 6 , which is a schematic structural diagram of a partial pixel array 2 . The pixel PU, 3) stores a pixel voltage of 6.6 volts, and its corresponding data line D3 has an equivalent voltage rms value of 6.6 volts in one picture time, so its transverse electric field E1 is proportional to both ends ( Ρ〇素Ρ〇, 3) The voltage difference between the elemental electrode and the data line D3 (6.6-6.6) = 0 volts. The pixel P(1,4) stores a voltage of 2 volts, and the equivalent voltage of the corresponding data line D4 is 2 volts, and the transverse electric field E2 is proportional to the voltage difference between the two ends (2_2)=〇 volt. Similarly, the transverse electric fields E3 and Eq corresponding to the pixels p(2,3) and P(2' 4) are proportional to the corresponding voltage difference (6.4-2)=4.4 and the voltage difference (6.6-2.5). ) = 43. Therefore, the two pixels P(2, 3) and P(2' 4) in the second column are subjected to electric fields, and the average light leakage brightness is much larger than the two pixels P(1 '3) and P in the first column. 1,4) The average light leakage brightness caused by the influence of the electric fields El and E2. Therefore, when we return to Figure 5 to see the whole list of elements, we will find that the light leakage of the second column will be more serious than that of the first column. This is the small thin stripes that cause obvious bright _ dark interlacing. s reason. If a black window is inserted in the center of the screen, the light and dark lines in the upper and lower display areas of the black window are more obvious. After TW1948PA 10 !29115〇, let wr to the most sweeping sweeping system be scanned in sequence. The thin film transistors connected to the scanning line are cut off. During the film = body cutoff period, the voltage is supplied to all f lines. So, let

Check: In the time when the pixel voltage is maintained, 'the corresponding data line is felt, the equivalent electric power value of the prime voltage change is the same as the pixel of the same column but different lines: the effect voltage _ value is very close . Its closeness to _ degree is far superior to the traditional practice, and the quality of the picture is improved. Wherein the first to the last scan is scanned; the sum of the required time and the time when the thin film transistor is cut off is a picture time "month", and Fig. 7 is a preferred embodiment of the present invention DESCRIPTION OF THE LCD: The same components as those described above are given the same component numbers. Liquid crystal display = 600 includes pixel arrays 6〇2, N+1 data lines D(1) to D(N+1), and scan lines S (1) S (M), data driving circuit 6〇4 and scan driving circuit 6〇6.

The pixel array 602 has the same circuit structure as the above pixel array 2, for example, including 20 columns and 35 rows of flip pixel matrices, that is, μ is 2〇, N is . The data driving circuit 602 is via the data line D(1)~ D (36) is electrically connected to the pixel array 6〇2 and used to output the pixel voltage. The scan driving circuit 6〇4 is electrically connected to the pixel array via the scan lines S(l—) to S(2G). And used to The scanning signal is output to each of the scanning lines S(1)~s(2〇), wherein each pixel p is denoted by p(M,N) in the seventh picture, for example, the first-column-line pixel is marked as ρ(1) , hehe.

TW1948PA 11 1291150 Please refer to FIG. 8 , which is a flow chart of a driving method of a liquid crystal display device applied to a preferred embodiment of the present invention. The driving method of this embodiment is used, for example, in the above liquid crystal display 600. First, in step 8〇4, in the first time T1, the scan driving circuit 606 sequentially scans from the first scan line s(1) to the second scan line S(20), and the data drive circuit 6〇4 The pixel array 602 is driven via the data lines D(1) to D(36) such that each pixel p in the pixel array 602 has a pixel voltage of opposite polarity to the pixel P adjacent to the top, bottom, left, and right. Next, in step 806, in the second time T2, the thin film transistors (not shown in FIG. 7) coupled to the scan lines s(1)-8(2〇) in the pixel array 602 are turned off. And providing a data line connected by the first voltage V1 to the pixel P driven by the positive polarity, and providing the second voltage V2 to the data line connected to the pixel P driven by the negative polarity. One of the picture times includes the first time T1 and the second time T2. Further, the liquid crystal display 600 drives the pixel p coupled to the data lines D(1), D(3), ... D(35) with a positive pixel voltage in the first time τι, and the negative electrode The pixel voltage is coupled to the pixel P coupled to the data lines D(2), D(4), ... (36) to input the pixel voltage corresponding to the first picture F1 into the pixel array 602' And maintain a face-to-face time. Then, in the second time T2, since the thin film φ transistor, for example, the thin film transistor 20 depicted in FIG. 1 is cut off, each halogen P can no longer receive the pixel voltage on the data line D. . At this time, the data driving circuit 604 outputs the first voltage V1 to the data lines D(1), D(3)··D(35), and outputs the first power C V2 to the data lines d(2), D(4)...D. (36) and maintain the second time T2. In this embodiment, the voltages V1 and V2 are maintained for the second time T2 such that the equivalent voltage rms values on each of the data lines D are closer to each other within one picture time. Please refer to Figures 9A and 9B at the same time. Figures 9A and 9B show the voltage changes over time on each data line during a picture time.

First look at the data line 叩), the data driving circuit 604 on the investigation ^ (3), continue to turn out the positive pixel voltage ^ volts to connect with it, the prime P' indicates that the data line D3 continues to output with the time axis In volts until the second T1. Similarly, the fourth line indicates the data line D(4), which continues from time το : 2.0 volts to time T1. Next, the voltage across all data lines D during the second time T2 is maintained at 9 volts. Please refer to Figure 10A and 1GB, which are the voltages that vary with time on each data line during the time. As shown in the display condition of Fig. 9, the liquid crystal display 600 displays the first picture? After 1 , the second picture F2° after the polarity inversion is displayed as the value of the 3rd line listed in the above 1G chart, indicating that the data line D(3)IU has the time axis T continuously outputting 2 volts to the time T1. . Similarly, line 4 represents data line D(4), with the output axis continuing to output 6 6 volts to interval T1. Then, using the voltage changes on each data line on the 9th and 10th graphs, calculate the equivalent voltage ms value of each of the data lines D1 to D36 corresponding to each pixel p during the maintenance of the pixel voltage, and Each pixel p is perceived as the equivalent electric |rms value on the corresponding data line D in the nth mesh. Please refer to 帛u diagram: It lists the equivalent voltage rms value of the voltage change of the pixel on the data line D. And comparing the values in the 11th and 4th figures, you can see that the 昼-昼素? During the period of maintaining the pixel voltage, the equivalent voltage rms value of the pixel voltage change on the corresponding data line D is compared with the equivalent voltage of the same column but different rows of pixels ρ. The traditional approach is very close, so that the adjacent two columns of pixels are subjected to horizontal electricity.

TW1948PA 13 1291150% of the effects, the resulting average light leakage phenomenon is closer to each other. Further, the effect of the present invention will be described, and FIG. 6 is made by taking four elements of P (1, 3), P (1, 4), P (2 ' 3) and p (2, 4) as an example. Further explanation, and another structural diagram of the four halogens p is shown in Fig. 12. Please refer to FIG. 12, which is a schematic structural diagram of a partial pixel array 602. As can be seen from Fig. 12, in the first picture F1, the pixel electrode of the pixel p(1,3) has a pixel voltage of 6.6 volts, and the equivalent voltage rms value of the pixel is obtained from the first picture. It is 7. 9 volts, so its transverse electric field E1 is proportional to the voltage difference between the pixel electrode of pixel p(1,3) and data line D3. This voltage difference is 7 9_6 6=ι 3 volts. Similarly, the transverse electric field E2 of Alizarin P(1,4) is proportional to the voltage difference of 4.6 volts, and the transverse electric field of the prime Ρ(2,3) is proportional to the voltage difference of 5.9 volts. The transverse electric field Ε4 of the prime (2, 4) is proportional to the voltage difference of Q1 volts. As mentioned above, the adjacent two transverse electric fields E1, and E2 affect the average light leakage brightness of the two pixels P(1,3) and ρ(ι,4) in the i-th column, which is proportional to the two voltage differences (1.3V+ The average of 4.6V) is 2.95ν. The electric field E3, E4, the average light leakage brightness of the two elements P (2, 3) and P (2, 4) affected by the second column is proportional to the other two voltage differences (5·9ν+0·1ν) The average is 3V. Therefore, it can be seen that the second column of Lu Su is affected by the electric fields E1, E2, and E3, and E4, and the degree of light leakage is very close. This also represents the difference between each column of pixels affected by cross talk. Will be closer, close to the human eye has been able to distinguish the bright and dark staggered small thin stripes, so that the quality of the displayed picture is improved. However, those skilled in the art can adjust the length of the second time T2 according to the voltages νι >, V2 input in the second time T2, for example, the voltage vi and the time is T2', so the voltages V1 and V2 are larger. The second time required is shorter. In the present embodiment, the magnitude of the voltage of the voltage νι W W and the length of the second time T2 are not particularly limited. ’,

However, those skilled in the art can adjust the length of the second time T2 according to the voltage of the person V2 at the second time T2 (10). For example, the voltage ~V2 is inversely proportional to the time. Further, the first voltage V1 can be the data driving circuit 604. The maximum voltage value under the positive polarity drive, and the second voltage V2 is the maximum voltage value of the data drive circuit under the negative polarity drive. Alternatively, the first voltage νι and the second voltage V2 are both the voltage level of the common electrode voltage or the pixel voltage driven by the positive and negative polarity of the common voltage, and the voltage is the data driving circuit driven by the positive polarity. The minimum voltage that can be output, and the second voltage is the negative

The source, as long as it can be input to the data line in the second time, the first voltage VI and the second voltage V2 can also be generated by other circuits. Therefore, the larger the electric MV1, V2, the shorter the second time τ2 is required. In the present embodiment, the lengths of the voltages of the voltages V1 and Vk and the second time are not particularly limited. As long as the per-line pixels are subjected to crosstalk (the difference between (10) μ仏(4) is more averaged, the display screen is displayed. There is no obvious bright and fine lines. In addition, the first voltage V1 and the second voltage v2 are not particularly limited in this embodiment, although the present invention has been disclosed in a preferred embodiment as above. However, it is not intended to limit the invention, and any person skilled in the art can make various changes and retouchings without departing from the scope of the invention. Therefore, the scope of protection of the present invention is attached to the application. The scope defined by the patent scope shall prevail.
