Embodiment Construction

[0042] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0043] In the prior art solution, when producing each screen, it is necessary to verify whether the white point of the screen is within an allowable threshold range. If it is, it is determined that the display screen is qualified; otherwise, it is determined that the display screen is not. qualified.

[0044]However, the same batch of display screens of the same model that have only passed the white point verification may not have the same d...

Abstract

The embodiment of the present invention discloses a screen calibration method and equipment, wherein the method includes: measuring the chromaticity value of each color block picture in the L color block pictures of the target picture displayed on the target screen, and obtaining the L color block pictures The measured chromaticity value of each color block picture in the color block picture, the target picture includes N color block pictures, N is greater than L, and L is a positive integer; Measure the chromaticity value, determine the estimated chromaticity value of each color block picture in the N-L color block pictures except the described L color block pictures in the target picture; The measured chromaticity values ​​of the color patch pictures are corrected to corresponding expected chromaticity values, and the estimated chromaticity values ​​of each of the N-L color patch pictures are corrected to corresponding expected chromaticity values. This solution effectively shortens the time spent on screen calibration, and improves the efficiency of screen calibration to a large extent.

Description

technical field [0001] The present invention relates to the technical field of display screen correction for unlocking a mobile terminal, and in particular, to a screen correction method and device. Background technique [0002] In the prior art solution, the screen manufacturer needs to verify whether the white point of each screen is within an allowable threshold range when producing the screen, and if it is within the threshold range, the screen is considered qualified. However, there are also large differences in the off-center orientation of the screens from different batches, which leads to inconsistencies between screens of the same model, so further correction of the screen color is required. The traditional screen correction method needs to measure the chromaticity value of each color block on the display screen one by one. If the measured chromaticity value of a color block does not meet the requirements, the chromaticity value of the color block can be corrected t...
