Embodiment Construction

[0037] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

[0038] A kind of liquid crystal display of the present invention, as image 3 As shown, the liquid crystal display of the present invention is provided with a display panel 10 , a timing controller 20 , and a plurality of source drivers (Source ICs) 30 . The timing controller 20 includes a timing annunciator 21 and a timing control chip (T-con IC) 22 connected to the timing annunciator 21, wherein the timing signal driver 21 sequentially generates the R signal, the G signal, and the B signal through timing control. The chip (T-con) 22 tran...

Abstract

The invention provides a color cast control method for a liquid crystal display. The liquid crystal display is provided with a display panel and a timing control chip. Color compensation tables are arranged in the timing control chip. The display panel of the liquid crystal display is divided into a plurality of regions. Each region corresponds to a color compensation table in the timing control chip. Regional color compensation or overall color compensation is carried out on the display panel according to whether a viewer is at the middle position of the display panel or not. According to the method provided by the invention, regional color compensation and overall color compensation are combined to realize different color compensation methods in the cases of envisaging and squinting; different color compensation parameters are used in different regions in the case of squinting; the problem of color cast of a large viewing angle is improved; an intelligent sensing module is used to realize automatic color compensation selection.

Description

technical field [0001] The invention belongs to the field of liquid crystal displays, in particular to a color shift control method of a liquid crystal display. Background technique [0002] A liquid crystal display (LCD) has gradually become one of the fastest-growing flat panel displays due to its lightness and thinness. With the development of technology, the size of TV panels is getting bigger and bigger, and the resolution is getting bigger and bigger. As the size increases, some problems inevitably arise. [0003] As we all know, when customers look at the center of the LCD monitor, the color of the picture is normal, but when they squint, they will find that the LCD monitor has a color washout problem; When the size of the LCD monitor is larger, the color shift phenomenon is more serious. [0004] Most of the existing liquid crystal displays use light-emitting diodes (LEDs) as backlight sources. Since the characteristic wavelengths of red light, green light, and b...
