Abstract

The embodiment of the invention discloses a display-panel detection method, device and system. The display-panel detection method includes the steps that the power voltage is put into a plurality of display panels in a mother substrate; preset driving signals are transmitted to the multiple display panels to drive the display panels to display preset test frames; frame images when the display panels display the preset test frames are collected; the frame images are detected according to the preset defect detection rule to complete frame detection of the multiple display panels in the mother substrate. By means of the display-panel detection method, frame detection of the display panels can be rapidly completed, and meanwhile it can be avoided that the mass abnormal conditions of the defected display panels appear.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel detection method, device and system. Background technique [0002] Currently, liquid crystal display panels are widely used in electronic devices such as mobile phones, tablet computers, and computer monitors. In the liquid crystal display panel manufacturing process, the lighting test process is an important process in the liquid crystal display panel. The lighting test ensures the quality of the display panel, for example, it is used to detect whether the display panel has defective pixels or other defects. The traditional lighting test of the liquid crystal display panel is to cut the display panel from the mother substrate into individual display panels, and then conduct a lighting test on the individual display panels to check out defective products. Therefore, this single board detection method consumes a lot of equipment and manpower. This single...
