Embodiment Construction

[0013] The specific implementation manners of the present invention will be described in further detail below with reference to the accompanying drawings.

[0014] In the prior art, in order to solve the color separation phenomenon produced by the FSC-LCD, a stencil algorithm is proposed. As far as the traditional field color gamut liquid crystal display is concerned, when there is a relative speed between the human eye and the image, it will be seen that the three color fields of red (R), green (G) and blue (B) are staggered on the retina to form a For this reason, the main focus of the Stencil algorithm is to try to reduce the light intensity of the R, G, and B three color fields, so as to reduce the intensity of the color bands pulled out due to staggering on the retina, so as to suppress color separation. At the same time, in order to maintain the original image, another color field is inserted to display the main intensity and rough color of the overall image. The origina...

Abstract

The invention provides a field color gamut liquid crystal display, comprising a backlight. The backlight consists of three light emitting diodes sequentially emitting red light, green light and blue light, and when a red sub-screen, a green sub-screen and a blue sub-screen are displayed, the brightness of the backlight is determined by lookup table of a current liquid crystal signal and the liquid crystal signal of a former picture. By adopting the field color gamut liquid crystal display, table lookup is carried out on the current liquid crystal signal and the liquid crystal signal of the former picture, and a product of the original backlight signal and the current liquid crystal signal is divided by the result of the lookup table to obtain a corrected backlight signal. Therefore, the phenomenon of color error or color offset caused by low response speed of liquid crystal is eliminated through changing the brightness of the backlight.

Description

technical field [0001] The invention relates to a driving technology of a liquid crystal display, in particular to a brightness compensation technology of a backlight source in a field color gamut liquid crystal display. Background technique [0002] Field Sequential Color Liquid Crystal Display (FSC-LCD) is an ultra-thin liquid crystal display with high resolution and high color saturation. The screen, through the persistence of vision of the human eye, uses the time-mixing method to accumulate the three primary colors on the retina to synthesize and present a color image. Because the display does not need to use color filters, it greatly improves the light transmittance, reduces power consumption and manufacturing costs. In addition, the field color gamut liquid crystal display greatly increases the pixel aperture ratio to improve the resolution and color of the displayed image. saturation. [0003] On the other hand, although the field color gamut liquid crystal display...
