Example Embodiment

[0032] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present invention are shown in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0033] It should be noted that when an element is referred to as being "disposed on" another element, it may be directly on the other element or a central element may also exist. When an element is considered to be "connected" to another element, it can be directly connected to the other element or an intermediate element may be present at the same time. The terms "vertical", "horizontal", "left", "right", "top", "bottom", "bottom", "top" and similar expressions...

Abstract

The present invention relates to a display screen parameter setting method comprising: inputting a current 3-Gamma voltage distribution approach and a current white color coordinate; adjusting the current white color coordinate to obtain a target white color coordinate; selectively testing the brightness of at least three current grayscale frames corresponding to the target white color coordinate; calculating the brightness of a plurality of preset position grayscale frames based on the tested brightness of the at least three current grayscale frames; acquiring a gamma curve according to the brightness of the plurality of preset position grayscale frames; acquiring a new 3-Gamma voltage distribution approach according to the gamma curve and outputting the new 3-Gamma voltage distribution approach. The display screen parameter setting method can greatly shorten the time to test the grayscale frames so as to further shorten the burning time of the entire 3-Gamma and to improve production efficiency.

Description

technical field [0001] The invention relates to the field of display screen testing, in particular to a 3-gamma burning method. Background technique [0002] Due to the chromaticity deviation of the backlight of the display screen and the deviation of the glass, the display effect of different display screens will be different. For example, the white screen of the display screen will often appear bluish or yellowish, that is, it is actually composed of three colors: red, green and blue. The white color coordinates of the display are not standard white color coordinates, and therefore the transition of each grayscale picture corresponding to the actual white color coordinates is not smooth, thereby affecting the display effect of the display screen. At present, the target white color coordinates are obtained by adjusting the white color coordinates to the target white color coordinates, that is, re-adjusting the red, green, and blue; and at the same time, adjusting the gamma ...
