The LCD monitor 1G _〗 is based on 3, and the (4) material signal is transferred to 3 data lines through the solution. The control signals CKH, CKH2, and ckh3 control the solution. The control switches SWri_sw, sWgi_si, SWB1-SWBn of the king device, the data signals can be written into each pixel unit through a corresponding multiplexer according to a predetermined sequence. 凊 Referring to FIG. 2, the timing diagram of FIG. 2 is said. In the prior art, a method of driving a liquid crystal display using a Row-Inversion method is used. In FIG. 2, VGATE+ and VGATE_ represent outputs to a gate during a positive polarity and a negative polarity driving cycle, respectively. The gate signal of the line, CKHl-CKH3 represents the control signal applied to the control switch in sequence, the common voltage of the Vcomr meter liquid crystal display 10 (c〇mm〇nV〇itage), VpiXEL+(R), VPIXEL+(G) and VpiXEL+ (9) Representing the voltage levels of the pixel cells that are lightly connected to the red, green, and blue data lines during the positive polarity driving cycle, respectively, represented by the fine broken line, the bold broken line, and the dotted line in FIG.

The broken line, the bold broken line and the dotted line are shown. As shown in FIG. 2, the red, green and blue data lines and the source driving circuit 12 are electrically connected in sequence by sequentially applying the control signal CKHrCKH3. Therefore, the data is written in the order of red-green-blue. In the positive polarity driving period, when the gate signal Vg applied to a pole line of * 7 200826047 is high, the TFT _ in the image sim unit of m to the gate line will be measured, so that _ The electric valley connected to the pixel unit of the gate line can be electrically connected to the corresponding data line.

When the material signal generated by the source driving circuit 12 is transmitted to the blue data line through the multiplexer 2 (in the second picture, the +(9) will increase accordingly. When the pixel is as TFT_ After the turn-off (Tflrst in the figure), it is represented by the 'red, green, and blue pixel unit potentials and the long-range H-recorded liquid crystal LUG), and vlc+(b) in the positive polarity driving period. Similarly, during the negative polarity driving period, when the TFT switch in the pixel unit is turned off (T_d in FIG. 2), between the potential of the red t green and blue pixel units and the common dependence in the negative polarity driving period The difference is represented by liquid day and day pressures VLC_(R), vLC_(G), and vlc_(b), respectively. Regardless of the positive and negative polarity driving cycles, the intensity of the light 2 that can be controlled by the pixel unit and the liquid crystal. In the normal, crane cycle, when the TFT switch in the pixel unit is turned off (Fig. 2, ^ s , . , .. Η 丨~iflrst), the red, the supervisor, and the 4-color pixel unit correspond. The liquid crystal voltage relationship is as follows: Vlo^Vwg)〉^(9).

The pixel units are sequentially written in order. During the positive driving period, when the gate signal Vgate+ applied to a gate line is high, the 2TFT switch in the pixel unit coupled to the gate line is turned on, so that the pixel unit coupled to the gate line is turned on. The capacitor inside can be electrically connected to the corresponding data line. Referring to FIG. 4, when the control signal CKHrCKH is sequentially applied, the first embodiment of the present invention sequentially turns on the control switches corresponding to the blue, green, and red data lines in each of the demultiplexers, so that the source is The data signal b generated by the driving circuit 32 is written into the corresponding pixel unit in the order of blue_green_red through the open control switch. As mentioned earlier, due to the parasitic capacitance between the data lines, when the potential of a data line changes, the adjacent data line potential is also affected. Assume that in the 4th ®, the multiplexer DUX2 is also explained. The v_ and VgatE-departure tables are between the positive polarity and the 贞 polarity _ occupational output to the _ line g. The extreme signal 'V_+(8) stands for The positive polarity of the nano-cell unit & voltage level ' and VPIXEL- (8) represents the voltage level of the pixel unit core during the negative polarity driving period. During the positive polarity driving period, the voltage level of the pixel unit ymEL+(8) will rise three times when the control signal CKHrCKHi has a high potential: the first time is because the data signal generated by the source driving circuit 32 is multiplexed. • When DUX2 is transmitted to the blue data line (T1 in Figure 4); the second time is due to 13 200826047. The data signal generated by the source driver circuit 32 is transmitted to the adjacent blue data line b2. When the green poor material line G2 (the light power generated by the parasitic capacitance between the data lines in Fig. 4 is caused; the third time is because the data signal generated by the source driving circuit 32 is transmitted to the adjacent In the case of the blue data line & red data line & (Fig. 4, D3), the surface generated by the parasitic capacitance between the material and the wire is caused by the electric charge. In the negative polarity driving cycle, Recording the electric fresh bit νΡ·_(8) will (4) drop three times when the control signal CKHrCKH has a high potential: the first time because the source drive circuit 3 ^ kg generated the data signal it over solved the multi-master book & When the blue data line is 氐 (τ4 in Figure 4), the second time is due to the source drive. The data signal generated by the circuit % is transmitted to the green chip adjacent to the blue data line & 5), and the parasitic capacitance between the data lines is generated due to the information generated by the source drive road 32. Adjacent to the red data line & of the blue data line Β2 (% in Figure 4, the coupling voltage generated by the parasitic capacitance between the data lines. Similarly, Figure 5 illustrates the parasitic thunder饴u A Wang Baogu's influence on the voltage level of the pixel early 2' and the 6th figure shows the effect of the parasitic capacitance on the voltage level of the Pm. In the process of writing the poor material signal to the data line, the power supply line V! potential V _ μ Ο and the power source line % potential VC2 are all in the figure. Fixed, for example, the potential Vci and the potential VC2 respectively maintain the C2 knife at a low potential and a high potential. After the data signal is written to the last data line, the data green 4 stomach material 、,, 士一-贝枓线Stained, and after the corresponding gate line is closed, the embodiment of the present invention can change the power line % and % Potential, 14 200826047 For example, turn the power line V $ two / ^ private Vci from low to high, and turn the power line 2Vc2 from low to low. Thus, the potential conversion of the power line will be:: The coupling port causes a pressure difference, and then provides a coupling voltage to the corresponding pixel unit to compensate for different degrees of color shift. 凊Chang tea test 4, assuming that the user wants to adjust the large blue pixel liquid crystal voltage VLC+ ( B) and the absolute value of VLC_(B), it is necessary to increase the value of the pixel potential VpIXEL+(B) at Tflrst during the positive polarity driving period, and decrease the pixel potential VPIXEL_(B^Tsec()nd during the negative polarity driving period. The value. At this time, in the positive polarity driving period, after the data signal is written into the last data line, the data line is floated, and before the corresponding gate line is turned off, the first embodiment of the present invention can connect the power line V] The potential is changed from a low potential to a south potential to provide a corresponding coupling capacitance-pressure difference ^^, and then a corresponding blue data line-coupling voltage ΔVcu is selected, so that VP1XEL+(8) can be simultaneously increased at I>irst The value and the absolute value of the blue pixel liquid crystal voltage vLc+(9). Similarly, in the negative polarity driving period, after the data signal is written to the last data line, and before the corresponding gate line is turned off, the first embodiment of the present invention can set the potential of the power line VC VC1 from high. The potential is turned to a low potential to provide a corresponding surface-to-electricity difference Δν〗 and to provide a corresponding blue data line with a handle voltage Δ VC1 - Β, thus reducing the value of Vpixel_(b) at Ts_d And increase the absolute value of the blue pixel liquid crystal voltage VLC_(B). In Fig. 4, the value of VpiXEL+(B) and Vpix]£L-(B) after 3 weeks of this day is represented by a fine broken line. Assume that the user wants to reduce the absolute value of the liquid crystal voltage VlC+(B) and Vl〇〇B) of the color-adjusting pixel. 2008. The temperature of the pixel potential is reduced by u during the driving cycle of the pole, and is increased during the driving period of the negative polarity. The pixel potential ν Ρ · (9) is at the value of ^: this day spreads the positive polarity driving week _, the first embodiment of the present invention can be used before the data signal is written to the last data, after the JL is closed at the corresponding gate line Will: the source line V2 ^ bit ve2 from high potential to low potential to provide the coupled coupling valley - pressure Α Δν2 ' and then provide the corresponding blue data line _ coupling voltage ^ Vc2 - Β so can keep the same VpKEL + (8) The absolute value of the value at the time of the fineness and the blue pixel liquid crystal voltage KB). Similarly, in the negative polarity driving period, after the data signal is written into the last-bar line, and before the corresponding gate line is turned off, the first pass of the present invention can lower the potential U of the power line. The potential is turned to a high potential to provide a corresponding capacitance - ^ Δν2, thereby providing a blue data line for the subtraction - the age of the core VG2 - Β, the field can increase the value of Vpl__ Ts_d, and reduce the liquid crystal voltage of the color pixel L) is absolutely noisy. In the 4th SJ, the value of Vp_(9) and (8) of this _ is represented by a bold broken line. In Fig. 4, the value of VP_(B) and vPiXEL_(B) adjusted by the power supply line % and the corresponding coupling capacitance is represented by a thin broken line, and the bold broken line represents the transmission power V2. And the value of Vpixel-(B) after the response of the capacitor to the capacitor. The values of the coupling voltages Δνα - Β and B are related to the capacitance values of the corresponding coupling capacitors and the magnitudes of the differential pressures Δν!, Δ%. Therefore, the first embodiment of the present invention can elastically adjust the blue pixel liquid crystal voltage V^+(B) by applying different voltage differences Δ%, AV2 to the power supply lines V!, V2, or using coupling capacitances of different capacitance values. And the absolute value of VLC_(B). As shown in Fig. 4, taking the positive polarity driving cycle as an example, the absolute value of the liquid crystal voltage VLC_up(B) after adjusting the voltage of 16200826047 can be greater than the value of the original liquid crystal voltage vlc+(b), or the value of 邑, or The absolute value of the adjusted liquid crystal voltage VLCJX) wn(b) may be smaller than the absolute value of the original liquid crystal voltage Vlo(B). Therefore, the present invention can elastically correct the color shift of the blue pixel unit. Tong Liming again refers to Figure 5 and Figure 。. In Fig. 5, the fine broken line represents the value of the adjusted VPIxeUG) when the user wants to adjust the liquid crystal voltage of the green pixel, and the bold broken line represents the adjusted when the user wants to lower the green pixel liquid crystal voltage.

In the first embodiment of the present invention shown in Figs. 4 to 6, the data is written in the order of blue _. and red, but the present invention is also applicable to other data writing sequences. Referring to FIG. 7 to FIG. 9 , the timing charts of FIGS. 7 to 9 illustrate a method of inventing the second embodiment of the emitter-driven display 3G. In the second embodiment of the present invention, the control signals CKHi_CKH3 are sequentially applied to sequentially connect the color, green and blue data lines and the source driving circuit 32, so that the data is sequentially arranged in the order of red capping. Write to the pixel unit. ▲ As in the second embodiment of the present invention, in the second embodiment of the present invention, the potential V of the power supply line Vi during the writing of the data signal to the data line. And the power cord ^ electricity 200826047 C21 white is Q疋. The second embodiment of the present invention can change the potential of the sum V2 before the data signal is written to the last data, and the line corresponding to the line is _. In this way, the potential conversion of the power line will provide a secret voltage to the depletion pixel unit in the corresponding turn (4) "f" to "compensate" to compensate for the same degree of color shift. Similarly, the value of the combined voltage is related to the valley value and the private Δ% and Δ%. Therefore, the second embodiment of the present invention can also elastically adjust the absolute value of the pixel liquid crystal voltage by applying different differential pressures ΔΥι, Δ% to the power supply lines V, V2, or using different capacitances of different capacitance values. As shown in FIG. 7, the positive polarity driving cycle in the second embodiment of the present invention is taken as an example. The absolute value of the liquid crystal voltage VLC_up (6) after adjustment may be greater than the absolute value of the original liquid crystal voltage 'vLC+(8)' or the liquid crystal after the collision. The absolute value of the voltage Vu: -d_(8) may be smaller than the absolute value of the original liquid crystal voltage VLC+(B). As shown in Fig. 8, taking the positive polarity driving period in the first example of the present invention as an example, the absolute value of the adjusted liquid crystal voltage v[c(10)(9) may be greater than the absolute value of the original liquid crystal voltage VLC+(G), or adjusted. The absolute value of the subsequent liquid crystal voltage VLC_D0WN(G) may be smaller than the absolute value of the original liquid crystal voltage Vlc+(g). As shown in FIG. 9, taking the positive polarity driving period in the second embodiment of the present invention as an example, the absolute value of the adjusted liquid crystal voltage VLC_UP(R) may be greater than the absolute value of the original liquid crystal voltage VLC+(R), or The absolute value of the adjusted liquid crystal voltage Vlc_d〇wn(r) may be smaller than the absolute value of the original liquid crystal voltage VLC+(R). Therefore, the second embodiment of the present invention can elastically correct the color shift of each pixel unit in the red-green-blue writing order. Please refer to FIG. 10, which illustrates a flow chart of the driving method of the present invention applied to an active TFT liquid crystal display having an 18 200826047 multiplexed structure, which includes the steps of: j Step 102. _ in the pixel unit of the idle line to receive the data signal transmitted through the corresponding data line; Step 'HH.

After generating the combined voltage, the switch that closes the handle to the pixel unit of the gate line is closed. . The first and second embodiments of the present invention shown in FIGS. 4 to 9 can be applied to a liquid crystal display having a structure of 1 to 3, and can also be applied to a liquid crystal display using other structures. For example, the present invention can also be applied to a liquid crystal display without a multiplexer.
