Embodiment Construction

[0112] In order to make the purpose, technical solution and advantages of the present application clearer, the implementation manners of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0113] Fault detection of the display panel is usually performed by a fault detection system. The fault detection system includes: a fault detection device, a drive module and an image acquisition module, and the fault detection device is electrically connected to the drive module and the image acquisition module. When performing fault detection on a display panel based on the fault detection method in the related art, the current image acquisition module cannot support fault detection on a display panel with a higher resolution.

[0114] For example, assuming that the field of view of the image acquisition module is consistent with the effective display area of ​​the display panel, the resolution of the image acquisition module ...

Abstract

The invention discloses a display panel fault detection method and device system and a storage medium, and belongs to the technical field of display. The method comprises the following steps: drivinga plurality of sub-pixel groups of the display panel to emit light in sequence; when each sub-pixel group emits light, acquiring a bright image of a target area in the display panel through an image acquisition module; taking the brightness of the pixel to which each sub-pixel in each sub-pixel group belongs as the brightness of each sub-pixel in the bright-state image of the target area; and determining whether the sub-pixels of the display panel comprise brightness abnormal points according to the brightness of the sub-pixels of the display panel, wherein the brightness abnormal points comprise at least one of bright points and dark points. The problem that an existing image acquisition module cannot support fault detection of a high-resolution display panel is solved, fault detection can be conducted on the high-resolution display panel based on the fault detection method, and the fault detection method is used for fault detection of the display panel.

Description

technical field [0001] The present application relates to the field of display technology, and in particular to a fault detection method, device system and storage medium of a display panel. Background technique [0002] With the development of science and technology, more and more display panels are used in people's production and life. After the display panel is manufactured, it is usually necessary to perform fault detection on the display panel to determine whether the sub-pixels of the display panel include bright and dark spots. Wherein, both the bright spot and the dark spot are faulty sub-pixels, and the brightness of the light emitted by the bright spot is much higher than the brightness of the surrounding sub-pixels, and the brightness of the light emitted by the dark point is much smaller than the brightness of the surrounding sub-pixels. [0003] In the related art, a fault detection system is used to detect the fault of the display panel. The fault detection s...
