AI Technical Summary

Problems solved by technology

However, since the dielectric layer between the common electrode and the pixel electrode will be broken down during laser cutting, it may cause a short circuit between the common electrode and the pixel electrode, resulting in abnormal bright spots in the display device, which will cause the display device to be scrapped

Abstract

The invention provides a display device and a repair method thereof. The display device includes a substrate with a display area and a peripheral area adjacently arranged; a plurality of pixel units are arranged on the substrate and located in the display area, wherein the pixel units respectively include: a thin film transistor with A source, a drain, and a gate; a pixel electrode, electrically connected to the source of the thin film transistor; a common electrode, electrically connected to a common voltage; and a data line, respectively electrically connected to the drain of the thin film transistor; a particle disposed on the at least one pixel unit and located between the data line and the common electrode; a first cutting structure formed on the common electrode ; a second cutting structure formed on the pixel electrode; wherein, the first cutting structure is a closed shape, so that the first cutting structure surrounds the particles.

Description

technical field [0001] The present invention relates to a display device, and in particular to a display device capable of being repaired during production and a repairing method thereof. Background technique [0002] With the development of technology, display devices are widely used in many electronic products, such as mobile phones, tablet computers, watches and so on. In order to improve display quality, large-size, high-resolution, and high-brightness display devices emerge as the times require. However, it is inevitable that defective products will be produced during the production process, and it is necessary to repair the produced defective products to save production costs. [0003] Generally, in the process of manufacturing the active element array substrate of the display device, inspection procedures are performed to detect defects, and laser repair processing is performed on the defects. For the display device designed with the AHVA structure, during the produ...
