Embodiment Construction

[0025] figure 2 It is a timing diagram of the driving method of the color sequential display according to the first embodiment of the present invention. Please refer to figure 2 , this embodiment takes the application of the liquid crystal display panel of the color sequential method as an example. first here figure 2 It divides one picture period into 3 sub-picture periods, and each sub-picture period processes red (R), green (G) and blue (B) data and backlight respectively. Depend on figure 2 It can be seen that each sub-frame period 21 - 23 is divided into data writing periods 211 , 221 , 231 and backlight lighting periods 212 , 222 , 232 . During the data writing period 211 of the first sub-frame period 21 , the source driver first sends red data to each pixel. In the backlight lighting period 212 of the first sub-picture period 21 , the red, green and blue lights are all turned on for a preset period of time, and then only the red backlight remains, and the green...

Abstract

The invention discloses a method for driving a color sequence type display, which is suitable for reducing the color separation phenomenon of the color sequence type display. The method comprises the following steps: dividing each sub picture period into a data writing period and a backlight lightening period; transmitting data of first color in the data writing period; lightening the backlight of the first color in the first time in the back light lightening period; and lightening the backlight of at least one color in the second time in the backlight lightening period.

Description

technical field [0001] The present invention relates to a color sequential display technology, and in particular to a color sequential display driving method suitable for reducing color separation. Background technique [0002] With the development of optoelectronics and semiconductor technology, the vigorous development of flat-panel displays has been driven. Among many flat-panel displays, liquid crystal displays have become the market leader due to their superior characteristics such as high space utilization efficiency, low power consumption, no radiation, and low electromagnetic interference. mainstream. Wherein, the liquid crystal display includes a liquid crystal display panel and a backlight module. Since the liquid crystal display panel itself does not have the function of emitting light, a backlight module is configured to provide the surface light source required by the liquid crystal display panel, so that the liquid crystal display panel can achieve the display...
