Abstract

The invention provides a screen correction method, device and system and a logic board, and the method comprises the steps: receiving a test image, collected by a camera, displayed on an LCD spliced screen, and reading pre-generated reference data; determining test brightness according to the test image, and adjusting the test brightness according to the reference data so as to complete brightnessadjustment of the LCD spliced screen; and based on the adjusted test brightness, performing gray scale adjustment on the test images of different gray scales by utilizing the reference data so as torealize gray scale adjustment of the LCD spliced screen. According to the invention, correction is carried out by taking pre-generated reference data as a reference; the problem of different optical parameters of different batches is avoided, the brightness of the backlight light bar of the LCD spliced screen is adjusted according to the table and the test image, and then gray scale adjustment isperformed, so that the problems of non-uniform brightness and non-uniform display effect, namely gray scale inconsistency, caused by backlight brightness are solved.

Description

technical field [0001] The present application relates to the technical field of screen calibration, in particular to a screen calibration method, a screen calibration device, a screen calibration system and a logic board. Background technique [0002] There will be display problems in the display device. In related technologies, the display area of ​​the display is divided into multiple areas and points, and then the mapping relationship data of each area and point in the source color space and the target color space are collected in real time. To support subsequent corrections, the theoretical value of the color components of each area or point in the target color space is obtained and output according to the mapping relationship data, and then the actual color component data of each area or point of the display in the target color space is collected again, and compared Obtain the color uniformity error of each area or point, and judge whether the color uniformity error is...
