Field sequential color display and color sequence control method thereof

Abstract

The invention is applicable to the technical field of display and provides a field sequential color display and a color sequence control method thereof, wherein the field sequential color display comprises a display panel and a back light module, the back light module provides a back light source to the display panel, wherein the back light source comprises red back light, blue back light and green back light. The color sequence control method of the field sequential color display comprises the steps of sequentially dividing a picture frame cycle of the display panel to a first sub-picture frame period, a second sub-picture frame period and a third sub-picture frame period; sequentially providing blue green back light and the red back light in a first back light period of the first sub-picture frame period; sequentially providing magenta back light and the green backlight in a second back light period of the second sub-picture frame period; and sequentially providing yellow back light and the blue backlight in a third back light period of the third sub-picture frame period, thereby eliminating the color separation phenomenon and compensating the reduced overall brightness and the reduced image color brilliance caused by reduced light open time of a main color axis.

Description

technical field [0001] The invention belongs to the field of display technology, in particular to a field color sequential display and a color sequence control method thereof. Background technique [0002] With the evolution of optoelectronics and semiconductor technology, it has also led to the vigorous development of flat panel displays. Among many flat panel displays, liquid crystal displays (LCD for short) have high space utilization efficiency and low power consumption. , no radiation and low electromagnetic interference and other superior characteristics, has become the mainstream of the market. [0003] A liquid crystal display generally includes a liquid crystal display panel (Liquid Crystal Panel) and a backlight module (Black Light Module, BL for short). Since the liquid crystal display panel itself does not have the characteristic of self-illumination, the backlight module must be arranged under the liquid crystal display panel to provide the surface light source...
