Abstract

The embodiment of the invention discloses a display panel detection method and device. The method comprises the steps of obtaining detection information after multiple display panels are detected under different detection conditions, wherein the detection information comprises multiple pieces of display panel information, different detection conditions and corresponding detection results; according to the detection information, obtaining respective optimal detection conditions corresponding to at least one defect of each display panel from different detection conditions; adjusting detection parameters according to the respective optimal detection conditions corresponding to the defects, and detecting the display panel defects to be detected according to the detection parameters. By means of the embodiment, under the respective optimal detection conditions corresponding to the defects, the detection of the display panel defects is completed, and the accuracy and efficiency of defect detection are improved.

Description

technical field [0001] The invention relates to the field of display panels, in particular to a detection method and device for a display panel. Background technique [0002] In recent years, with the rapid development of optoelectronic technology and semiconductor manufacturing technology, the vigorous development of flat panel display technology has been driven. Among them, liquid crystal display devices are widely used in various information and communication due to their advantages of small size, light weight and high image quality. and consumer electronics. [0003] With the development of LCD panel production technology, it has entered the era of large-scale automated production. After the liquid crystal panel is manufactured, the liquid crystal panel may have defects, so how to accurately and quickly detect the defects of the liquid crystal panel is particularly important. Existing inspection methods can check defects by heating the liquid crystal panel to a certain...
