- the data driving time of the positive polarity sub-pixels VGd_1, VGd_3, and VGd_5 is longer, and the data driving time of the negative polarity sub-pixels VGd_2, VGd_4, and VGd_6 is shorter, so that the negative polarity sub-pixels VGd_2,
- the drop in the equivalent charging voltages of VGd_4 and VGd_6 forms a so-called low-voltage sub-pixel, so that the equivalent charging voltages of the positive-polarity sub-pixels VGd_1, VGd_3, and VGd_5 maintain the original charging signal to form a so-called high-voltage sub-pixel.

The charging time will be different, and the charging ability will be different, forming a high-voltage pixel unit and a low-voltage pixel unit. Arranged to improve the color cast. Therefore, it can be considered that this embodiment successfully improves the color shift phenomenon without affecting the transmittance of the panel.
