Display screen uniformity test method, terminal, and computer readable storage medium

Abstract

The invention discloses a display screen uniformity test method, a terminal and a computer readable storage medium. The display screen uniformity test method comprises the steps of: acquiring a display state picture of a to-be-tested screen, acquiring an effective region of the display state picture, and regarding the effective region as a test picture corresponding to the to-be-tested screen; acquiring a preset sample picture, and calculating a sample mean value of pixel values corresponding to the sample picture; and acquiring test pixel values corresponding to the test picture, comparing the test pixel values with the sample mean value, and determining a test result of uniformity of the to-be-tested screen according to a comparison result. The test result of the display screen uniformity test method can precisely reflect the overall uniformity of the to-be-tested screen; meanwhile, the test can be completed without technical personnel performing related technical operations, therebyavoiding test deviation caused by human factors, improving the precision of the test result, being conductive to reducing the time spent on the test and improving the efficiency of the uniformity test.

Description

technical field [0001] The present invention relates to the technical field of display screen testing, in particular to a display screen uniformity testing method, 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 display screen is uniform, the image display effect is good; if it is not uniform, the display effect is poor, and the displayed image will appear various traces. [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 the uniformity of the display. Since 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 unifor...

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
