Embodiment Construction

[0028] The technical content of the present invention will be described in detail below with reference to the drawings.

[0029] FIG. 1 is a schematic structural diagram of a color sequential liquid crystal display according to a preferred embodiment of the present invention. The color sequential liquid crystal display of the present invention includes a liquid crystal display (LCD) panel 10 , a backlight device 20 , an image data comparison unit 30 and an image data control device 40 . The liquid crystal display panel 10 has liquid crystals and a pixel array whose transmittance of the liquid crystals is controlled by applying a voltage. The liquid crystal display panel 10 applies different voltages according to the data signal to control the light quantity of the backlight passing through the liquid crystal to display different image pixels. The backlight device 20 provides the backlight required by the liquid crystal display panel 10 for displaying images. The backlight de...

Abstract

A color-order type liquid -crystal display and its drive method are disclosed. A pre-drive signal is inserted into two adjacent picture frames to change the grey-scale brightness ratio. The pre-drive signal can be regulated along with the grey-scale difference of two adjacent picture frames. The invention not only overcomes not good accuracy of panel color mixture resulted from liquid-crystal reaction time, but also solves the problem that the pixel display of liquid-crystal panel is not uniform resulted from the open time difference of different grid electrode series.

Description

technical field [0001] The invention relates to a color-sequential liquid crystal display and a driving method thereof, in particular to a color-sequential liquid crystal display and a driving method thereof that can effectively improve color mixing accuracy. Background technique [0002] A traditional thin film transistor liquid crystal display (TFT-LCD) uses a white backlight and utilizes three-color color filters of R, G, and B to achieve the effect of color display. The color sequential liquid crystal display does not use filters, but uses R, G, and B three-color light sources to emit light sequentially within a frame (frame), and uses the persistence of vision of the human eye to make the three colors Additive color mixing is done for color light to achieve the effect of color display. [0003] The liquid crystal display includes a liquid crystal panel, which is composed of a plurality of pixels in an array, and each pixel has upper and lower electrodes, and data signa...
