Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
In this application, the terms "upper", "lower", "left", "right", "front", "rear", "top", "bottom", "inner", "outer", "middle", "vertical", "horizontal", "lateral", "longitudinal", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings.

Since the number of Data lines (Data lines) in the Tri-Gate (Tri-Gate) driving scheme is reduced to 1/3 of the Normal (Normal) driving scheme and the number of scan lines (Gate lines) is increased to 3 times of the Normal driving scheme, the width and charging time of each Gate pulse (Gate pulse) in the Tri-Gate driving scheme are reduced to 1/3 of the Normal driving scheme, respectively. When the second mixed color picture is displayed, the charging rate of the next pixel is higher, and the charging rate of the previous pixel is lower, which can cause the problem of color cast or uneven display of the picture caused by insufficient charging rate caused by progressive scanning. Especially for high-resolution display devices, such as 8K and 16K display devices, the problem of color cast is more obvious because of the shorter charging time and the larger RC loading (resistive loading in screen).
