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...

Embodiment Construction

[0044] It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0045] The main idea of ​​the solution in the embodiment of the present invention is to obtain a picture of the display state of the screen to be tested, and obtain an effective area of ​​the picture of the display state as a test picture corresponding to the screen to be tested; to obtain a preset sample picture, and to calculate the Obtain 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 with the sample mean value, and determine the test result of the uniformity of the screen to be tested according to the comparison result .

[0046] The method for testing the uniformity of the display screen according to the embodiment of the present invention is mainly applied to a terminal for testing the...

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...
