Abstract

The invention provides an array substrate, a display panel and a display device, and belongs to the technical field of display. The array substrate comprises a display area and further comprises a through hole, an anti-cracking dam, a metal lead and a first data line, wherein the through hole is formed in the display area, the anti-cracking dam surrounds the through hole, the metal lead surrounds the anti-cracking dam, the first data line is divided into a first section and a second section by the through hole, the first section of the first data line is connected with one end of the metal lead, and the second section of the first data line is connected with the other end of the metal lead. Cracks at the edge of the through hole can be effectively detected through the array substrate.

Description

Technical field [0001] The present disclosure relates to the field of display technology, and in particular to an array substrate, a display panel and a display device. Background technique [0002] On-screen aperture technology can effectively increase the screen-to-body ratio of the display device and improve user experience. However, the edge of the opening is very prone to micro-cracks, resulting in poor display and reduced life of the display device. The prior art cannot effectively detect the hole edge cracks of the aperture screen, which seriously affects the quality control of the aperture screen. [0003] The above-mentioned information disclosed in the background section is only used to enhance the understanding of the background of the present disclosure, so it may include information that does not constitute the prior art known to those of ordinary skill in the art. Summary of the invention [0004] The purpose of the present disclosure is to provide an array substrate...
