The invention relates to a method and device for testing the brightness uniformity of a display panel. The method for testing brightness uniformity of a display panel includes: acquiring brightness data of a first display area at a preset position to obtain a first brightness data set; rotating the display panel at a preset angle and acquiring the second display area at a preset position The luminance data of the first luminance data set is obtained, and the second luminance data set is obtained; the luminance uniform value of the display panel is calculated according to the lowest value and the highest value of the luminance data in the first luminance data set and the second luminance data set. The method for testing the brightness uniformity of the display panel takes into account the bending angle of the curved display device, so that the calculated brightness uniform value can be closer to the brightness uniform value that the user feels when using the curved display device, thereby facilitating the display of the curved surface. The device is tested for brightness uniformity.
Description
technical field [0001] The present invention relates to the field of display technology, in particular to a method and device for testing the luminance uniformity of a display panel. Background technique [0002] With the development of display technology, there have been more and more curved display devices, such as curved mobile phones and curved wristbands. A curved display device usually includes a cover plate with a curvature and a flexible display panel attached to the cover plate. [0003] In the conventional technology, the brightness uniformity detection is usually performed when the display panel is flat. [0004] During the process of realizing the conventional technology, the applicant found that the conventional luminance uniformity detection method cannot be applied to the luminance uniformity detection of the curved display device. SUMMARY OF THE INVENTION [0005] Based on this, it is necessary to provide a method and device for testing the luminance unif...
