Display substrate and display apparatus

Abstract

The invention discloses a display substrate and a display apparatus. The display substrate includes a display area and a non-display area surrounding the display area, further includes a plurality of pads arranged on the non-display area, and an electrostatic protection circuit, wherein the pads and the pins of a display chip are correspondingly and electrically connected one by one, the electrostatic protection circuit is electrically connected with at least one pad for outputting the static electricity of the pad, the electrostatic protection circuit forms in the bonding area for bonding the display chip. According to the scheme, the at least one pad is electrically connected with the electrostatic protection circuit for outputting the static electricity of the pad, so that the short circuit caused by the static breakdown between the adjacent pads can be prevented, the electrostatic protection capability of the display substrate and the display device including the same is improved, and the manufacturing yield rate and the use reliability of the display substrate and the display device including the same are improved.

Description

Technical field [0001] The present disclosure generally relates to the field of display technology, and more particularly to a display substrate and a display device. Background technique [0002] Electro-Static Discharge (ESD, Electro-Static Discharge) is due to the large accumulation of static electricity during the process of display panel manufacturing. During the charge transfer process, it encounters thinner traces or intersecting lines, and the instantaneous current is too large. This kind of destruction phenomenon. [0003] With the increasing demand for PPI (Pixel per Inch), the size of the device is getting smaller and smaller, the line width of the metal and the distance between the metal and the metal are getting smaller and smaller. At the same time, the number of signal channels required by the display panel is also increasing, which also leads to an increase in the number of pins of integrated circuits that provide signals to the display panel. As a result, the num...

AI Technical Summary

Problems solved by technology

However, the bezel area of ​​the display panel is limited, so the spacing between adjacent pads will be reduced accordingly

Once a static charge is introduced on a certain pad, it will easily cause a short circuit between adjacent pads due to electrostatic breakdown, which will cause the subsequent integrated circuit to fail to provide signals to the display panel normally.
