Embodiment Construction

[0017] The invention relates to a color display method of a color sequential liquid crystal display, which uses three colors of red (R), blue (G) and green (G) as backlight sources to form different color Fields, color images are displayed by additive color mixing of these color fields. Moreover, the present invention further improves the way of color display by combining the lighting technology with the green color field as the sequential interval and the overdrive technology.

[0018] The method of using the green color field as the lighting interval can be divided into at least two types, the RGBG driving method and the BGRG driving method. The RGBG driving method is in the order of R→G→B→G in a frame time Illumination is performed, and the BGRG driving method is to perform illumination in the order of B→G→R→G in a frame time. In both methods, the green backlight is turned on twice as often as the red or blue backlight is turned on, and in the preferred method, the brightn...

Abstract

The invention discloses a color display method of a color-sequence liquid crystal display. The problem of color separation is improved by lifting a frequency of opening a green backlight. A reference red pixel or a reference blue pixel is selected according to a color attribute of a target color in an over-drive mode, so as to determine an over-drive value corresponding to a green color field and take the over-drive value as a green signal value which is actually output to a screen of the display, thereby improving the problem of color deviation.

Description

technical field [0001] The present invention relates to a color display technology, in particular to a color display method of a field-sequential-color liquid crystal display (FSC-LCD). Background technique [0002] Traditional thin-film transistor liquid crystal displays (Thin-Film transistor Liquid Crystal Displays, TFT-LCD) use a white backlight and a color filter equipped with three filters: red (R), blue (G), and green (G). The substrates are matched with each other to achieve the effect of color display. The color sequential liquid crystal display does not need to use red, blue and green filters, but uses red, blue, and green color fields to illuminate sequentially within a frame (Frame) time, using human vision The persistence phenomenon makes the three-color backlight add color mixing to achieve the display effect of full-color images. [0003] The phenomenon of color breakup (Color Breakup) often occurs when traditional color sequential liquid crystal displays dis...
