Problems solved by technology

In this way, in the liquid crystal display device of the time-division sequential driving method, one frame of data is composed of R subframe, G subframe and B subframe, and each frame has 1 / 3 time of the main frame, resulting in insufficient charging time of the sub-pixels, which affects The display effect of the display device; and due to the sequential driving of the RGB sub-pixels, at least 3 times the liquid crystal response speed is required, and due to the slow response speed of the current liquid crystal, there will also be problems of color mixing and color decomposition (ColorBreak Up) problems
