Test method, terminal, and computer-readable storage medium for uniformity of display screen

Abstract

The invention discloses a method for testing the uniformity of a display screen, a terminal and a computer-readable storage medium. By obtaining a display state picture of the screen to be tested, and obtaining the effective area of ​​the display state picture, it is used as the corresponding display area of ​​the screen to be tested. the test picture; obtain the preset sample picture, calculate the sample mean value of the pixel value corresponding to the sample picture; obtain the test pixel value corresponding to the test picture, compare the test pixel value and the sample mean value, and according to The test result of the uniformity of the screen to be tested is determined by comparing the results. The test results of the present invention can accurately reflect the overall uniformity of the screen to be tested; at the same time, the test of the present invention can be completed without technical personnel performing related technical operations, avoiding test deviations caused by human factors, and improving the accuracy of test results , which is also beneficial to reduce the time consumed by the test and improve the efficiency of the uniformity test.

Description

technical field [0001] The invention relates to the technical field of display screen testing, in particular to a test method for display screen uniformity, a terminal and a computer-readable storage medium. Background technique [0002] The brightness uniformity of the display screen reflects the quality of the display screen. If the screen is uniform, the image display effect is better; if it is not uniform, the display effect is poor, and various traces will appear on the displayed image. [0003] The traditional test method for the uniformity of the display screen is to use the combination of human vision and a luminance meter to judge whether the uniformity is good or bad. Because this method utilizes people's subjective feeling, it is easy to affect the evaluation result due to the difference of subjective feeling. Another common test method is the nine-point test method, that is, according to the brightness of the surrounding 8 pixels and the center pixel, the result...

Problems solved by technology

However, when using the nine-point test method, the selection of different pixel positions will affect the subsequent calculation results, and the inaccurate test results will be caused when the selected point position is inappropriate.

Moreover, the current TV sets are all curved TV sets, and the current test method is aimed at regular-shaped rectangular TV sets. The measurement method for curved TV sets also uses the measurement method for regular-shaped rectangular TV sets, which will also affect the uniformity of the results. Evaluate
