Problems solved by technology

In an ideal state, it is hoped that the chromaticity of the display panels produced in the same batch can be completely consistent, but in the actual production process, although the production process is the same, there will still be certain differences in the chromaticity of the same batch of products, resulting in the chromaticity of the product. Inconsistent degree indicators

Embodiment Construction

[0057] In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0058] In the embodiment of the present invention, the display panel may be a display panel in a liquid crystal display device, such as figure 1 As shown, the liquid crystal display device may include a backlight module 100 and a display panel 200 located on the light emitting side of the backlight module; The liquid crystal layer 203 between the film substrates. In practical applications, the color filter substrate includes color filt...

Abstract

The invention discloses a chroma adjustment method and device of display panels. Present white point color coordinate values of the different display panels are measured, and a target white point color coordinate value is determined according to the measured white point color coordinate values of the different display panels; and according to the present white point color coordinate values of different display panels and the target white point color coordinate value, initial data voltages of different color sub-pixels of the display panels are adjusted successively, so that the difference between each adjusted white point color coordinate value of the display panel and the target white point color coordinate value is lower than a preset value, and the data voltage after adjustment serves as a standard data voltage of the color sub-pixels of the display panels. The data voltages of the different color sub-pixels of the display panels are adjusted, so that the chroma of the display panels after adjustment basically equals the target white point color coordinate value, and the chroma of the display panels is more consistent.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a method and device for adjusting chromaticity of a display panel. Background technique [0002] In the field of display technology, a liquid crystal display panel (Liquid Crystal Display, LCD for short) has replaced a cathode ray tube (Cathode Ray Tube, CRT for short) display device. The liquid crystal display panel has many advantages such as thin body, low power consumption, and no radiation, and is widely used in the display field. [0003] The chromaticity of the liquid crystal display panel is an important index to measure the display performance, and the backlight and color film of the display device become the main factors determining the chromaticity. In an ideal state, it is hoped that the chromaticity of the display panels produced in the same batch can be completely consistent, but in the actual production process, although the production process is the same, there ...
