Embodiment Construction

[0035] In order to better illustrate the technical characteristics and structure of the present invention, the following is a detailed description in conjunction with preferred embodiments of the present invention and accompanying drawings.

[0036] refer to figure 1 , a flow chart of a white balance adjustment method provided in this embodiment, including steps:

[0037] S1: Input the white balance value of the standard sample into the display panel;

[0038] S2: controlling the display panel to display a test image with different grayscales, and obtaining full grayscale data of the display panel;

[0039] S3: Determine whether the acquired data is within the specification range, if so, enter the next process; if not, enter step S4;

[0040] S4: Recalculate the white balance value according to the difference between the obtained full gray scale data and the full gray scale data of the standard sample, input the calculated white balance value into the display panel, and retu...

Abstract

The invention provides a white balance adjusting method which comprises the steps that S1, the white balance value of a standard sample is input to a display panel; S2, the display panel is controlled to display a testing picture with different gray levels, and the full-gray-scale data of the display panel is acquired; S3, whether the acquired data are within a specification range is judged, if yes, the next manufacture procedure is executed, and if not, the step S4 is executed; S4, the white balance value is calculated again according to the difference value of the acquired full-gray-scale data and the full-gray-scale data of the standard sample, the calculated white balance value is input to the display panel, and the step S2 is executed again. According to the white balance adjusting method, white balance can be quickly and accurately adjusted, different modules are made to have the same visual performance, and yield loss caused by overspecification of gamma and chromaticity is reduced.

Description

technical field [0001] The invention relates to the technical field of display panel production, in particular to a white balance adjustment method and system, and a liquid crystal display manufacturing method. Background technique [0002] A liquid crystal display (LCD, Liquid Crystal Display) has many advantages such as a thin body, power saving, and no radiation, and thus has been widely used. Most of the liquid crystal display devices currently on the market are backlight liquid crystal display devices, which include a liquid crystal display panel and a backlight module. The working principle of the liquid crystal display panel is to place liquid crystal molecules between two parallel glass substrates, and control the liquid crystal molecules to change direction through the voltage applied to the glass substrates, and refract the light from the backlight module to produce a picture. [0003] Presently existing display devices, such as liquid crystal display devices, pla...
