The commonelectrode driving signal 60 may discharge the voltage of the darker luminance region to be displayed through the TFT element T2, so that the darker voltage region is closer to the voltage of the common electrode signal line Vst, decreasing the luminance of the darker luminance region.

Continuing with fig. 1 and 4, the charge driving TFT element T1 mainly used in the higher voltage bright area is designed as a Flip-pixel, and thedata line 10 outputs the data driving signal, which is shown in fig. 1 and Vd_mThe data driving line sequentially turns on the driving scanning sub-pixel Vd from top to bottom according to the scanning driving signals VGn, VGn +1, VGn +2 …_n-m、Vd_n+1-m、Vd_n+2-m… high Voltage Bright region Vp1a for data write, Vd_mIs sequentially written into the sub-pixels Vd_n-m、Vd_n+1-m、Vd_n+2-m… high voltage bright region Vp1a same polarity driving voltage, as shown in FIG. 1, Vd_mThe data driving signal of (1) is positive in polarity. Similarly, Vd_m+1Is sequentially written into the sub-pixels Vd_n-m+1、Vd_n+1-m+1、Vd_n+2-m+1… high voltage bright area Vp1a has the same polarity driving voltage, as shown in FIG. 1, the data driving signal of Vdm +1 has negative polarity, as shown in FIG. 1, the same time Vd_n-m、Vd_n+1-m、Vd_n+2-m… the high voltage bright area Vp1a and the low voltage dark area Vp1b are charged with the same polarity signals by the TFT device T1 for the high voltage bright area Vp1a and the low voltage dark area Vp1 b. To realize Vd_n-m、Vd_n+1-m、Vd_n+2-m… Low Voltage dark space Vp1b, another TFT element T2 is designed from the next level, for example VG_n+1Is VG_nThe lower scanning driving line of (1) is connected to a common electrode signal line Vst, which is lower than the positive polarity driving signal and higher than the negative polarity driving signal.

In one embodiment, when the firstsub-pixel region 50 is driven with negative polarity, thesecond sub-pixel region 60 is driven with positive polarity.

In this embodiment, it is ensured that the first sub-pixel realizes high voltage and the second sub-pixel realizes low voltage during negative polarity driving, and the high-low voltage alternation of the adjacent sub-pixels is realized, so as to achieve the purpose of improving color shift, since the first sub-pixel has a negative polarity and the second sub-pixel has a positive polarity, when the firstsub-pixel region 50 is driven with a negative polarity, thesecond sub-pixel region 60 is also negative in polarity, except that thesecond sub-pixel region 60 is discharged due to the secondactive switch 80, so that the voltage of the negative polarity of the firstsub-pixel region 50 is smaller than the voltage of the negative polarity of thesecond sub-pixel region 60, the driving voltage of the pixel is viewed as a voltage difference of the voltage of the negative polarity with respect to the voltage of the common electrode, therefore, the pixel voltage generated by the firstsub-pixel region 50 relative to the common electrode voltage is still larger than that of thesecond sub-pixel region 60, and the alternation of high and low voltages in the same sub-pixel is realized, thereby achieving the purpose of improving color cast.
