Problems solved by technology

Under this condition, the color liquid crystal display device driven by this field sequence can only display 8 colors of red, green, blue, yellow, cyan, purple, white and black. The color tone is relatively monotonous
If two colors of yellow and blue are used as the backlight, in the time displayed by each frame of image, the time occupied by yellow is 2 / 3, and the time occupied by blue is 1 / 3. This kind of field sequentially driven color liquid crystal The color of the display device is more dull

Embodiment Construction

[0019] The core of the driving method of the field sequentially driven color liquid crystal display device is: without changing the driving frequency of the backlight source of the field sequentially driven color liquid crystal display device, in each color region of monochrome display, change the frequency of the liquid crystal display element The driving frequency is to change the switching times of the liquid crystal display element so that it switches twice or more in a single-color display color zone.

[0020] See figure 1 , figure 1 It is a schematic diagram of driving a backlight source for two groups of colors in the present invention. As shown in the figure, when the backlight is two groups of colors, the figure shows a group of red (R) and a group of green (G) (LED lights of corresponding colors can be used), by changing the on or off of the liquid crystal display element The number of times off can achieve the purpose of rich colors, such as figure 1 In the fi...

Abstract

The invention relates to a driving method for driving a color liquid crystal display device by a field order. The color liquid crystal display device driven by the field order is provided with a backlight source formed by two or more than two different color groups, the backlight source respectively displays one time within the time of the color liquid crystal display device displaying one frame image, and the displaying time of a liquid crystal display element within a same color zone is more than or equal to two times. The color liquid crystal display device driven by the field order is greatly enhanced in colorful degree.

Description

technical field [0001] The invention relates to a driving method of a field sequential driving color liquid crystal display device. Background technique [0002] The existing field sequentially driven color liquid crystal display device, its structure is as attached Figure 6 As shown, it includes a field sequential drive liquid crystal display element 1 and a backlight 3, and a diffusion plate 2 is arranged between the field sequential drive liquid crystal display element 1 and the backlight 3, and the backlight 3 includes three groups of R (red), G (green), B (blue) evenly arranged LED lights 4. The backlight divides R (red), G (green), and B (blue) into three screens (fields) sequentially in time, and drives the liquid crystal display element 1 on or off in accordance with the field sequence to display a color image. attached Figure 7 It is divided into three screens (fields) by R (red), G (green), and B (blue), and with the opening or closing of the liquid crystal dis...
