Abstract
The present invention provides a display method for an LCD device with reduced color break-up, comprising the following steps: generating a control signal for each sub-frame, and displaying the sub-frames successively. The present invention generates, according to brightness of a screen to be displayed, second backlight control signals and second LC control signals for each display region in the each sub-frame and then, according to the second backlight control signals and the second LC control signals, displays a chromatic sub-frame and a plurality of monochromatic sub-frames successively so that the screen to be displayed can be viewed through human vision. The present invention can not only facilitate reducing color break-up (CBU) of the LCD device, but also can contributes to the LCD device advantaged by high contrast, high color saturation, low power consumption and low manufacturing costs.
