Embodiment Construction

[0052] Please refer to figure 1 , which shows a schematic diagram of a liquid crystal display device according to a first embodiment of the present invention. The liquid crystal display device 100 applied to the driving method of this embodiment can use the color sequential method to form a color image without using a color filter (Color Filter, CF), so as to reduce the cost of the color filter and improve The light transmittance of the liquid crystal display device 100 . The liquid crystal display device 100 includes a liquid crystal display panel 110 , a backlight module 120 and a timing control circuit (Timing Controller, TCON) 130 .

[0053] Please refer to figure 1 and figure 2 , figure 2 A schematic diagram showing a light source of the backlight module according to the first embodiment of the present invention. The backlight module 120 of this embodiment is provided with a plurality of different color light sources (not shown) to provide different color lights, w...

Abstract

The invention provides a driving method of a liquid crystal display. The driving method includes the following steps of in the first picture frame time, starting a first light source and supplying gray scale data of a first picture frame to a liquid crystal display panel, in the second picture frame time, starting a second light source and supplying gray scale data of a second picture frame to the liquid crystal display panel, in the third picture frame time, starting the first light source, the second light source and a third light source and supplying gray scale data of a third picture frame to a liquid crystal display panel. By means of the driving method of the liquid crystal display, a color separation phenomenon of a color sequence type liquid crystal display.

Description

technical field [0001] The invention relates to a driving method of a liquid crystal display device, in particular to a driving method of a color sequential (Field Color Sequential) liquid crystal display. Background technique [0002] Existing liquid crystal displays (Liquid Crystal Displays, LCDs) use white backlights and need to cooperate with color filters of different colors such as R, G, and B to achieve the effect of color display. In contrast, the Color Sequential liquid crystal display does not need to use a filter, but uses three-color light sources of R, G, and B to emit light sequentially within a frame time, which utilizes the vision of the human eye. In order to achieve the effect of color display, the three kinds of color lights are mixed to achieve the effect of color display. [0003] However, the color sequential liquid crystal display is prone to color breakup (CBU), which seriously affects the display quality of the display. At present, one of the metho...
