Abstract

The invention discloses a repair detection method and device of a display module, equipment and a storage medium. The repair detection method comprises the steps of obtaining a first anode current of a light-emitting element in a bad sub-pixel, and calculating first compensation data according to the first anode current; acquiring a second anode current corresponding to light-emitting elements in at least two pixel groups except the bad sub-pixel, and calculating second compensation data corresponding to the pixel group according to the second anode current corresponding to the pixel group; determining the maximum difference value in the difference values of the second compensation data and the first compensation data; judging whether the maximum difference value is greater than or equal to a preset threshold value or not; if so, prompting that the bad sub-pixel is successfully repaired; and if not, prompting that the repair of the bad sub-pixel fails. The repair detection method is used for detecting whether the display module is successfully repaired or not, the detection mode is more intelligent, and the accuracy of the detection result can be improved.

Description

technical field [0001] The present invention relates to the technical field of display module restoration, in particular to a repair detection method, device, equipment and storage medium of a display module. Background technique [0002] In the module packaging stage after the display panel is manufactured, it is usually necessary to conduct an electrical test on the display module to determine whether there are defective sub-pixels. Since the human eye is sensitive to bright light, it is especially necessary to detect whether there is a bright spot defect (the sub-pixel is always in a light-emitting state and cannot be turned off). [0003] figure 1 It is a structural schematic diagram of an existing display module, such as figure 1 As shown, the display module 10 includes a plurality of sub-pixels 101. The sub-pixels mainly include light-emitting elements and pixel circuits (not shown) for driving the light-emitting elements to emit light. After testing, the plurality o...
