AI Technical Summary

⚠Technical Problem

Existing display devices have poor electrostatic protection capabilities, and the key pins and related circuits of the driver chip are easily damaged, affecting display or touch performance. At the same time, there are idle terminals on the screen, resulting in wasted resources.

⚗Method used

In the display module, the pins of the driver chip are connected to the bonding terminals of the screen. Different electrostatic discharge (ESD) protection circuits are used to share the ESD load. When the screen is working, the bonding terminals are disconnected from the display area circuit structure to share the ESD load of the pins. At the same time, the idle bonding terminals are used to improve the ESD protection capability.

🎯Benefits of technology

This improves the electrostatic discharge protection capability of the display module, reduces the risk of damage to the driver chip pins and related circuits, ensures the reliability of display and touch performance, and reduces resource waste.

Abstract

Embodiments of the present application disclose a display module and a display device. A driving chip is configured to generate a screen driving signal according to a signal transmitted by a first pin. A non-display area of the screen includes a plurality of first bonding terminals. The first bonding terminals are not connected to or not connected with circuit structures in a display area of the screen when the screen works according to the screen driving signal. By connecting the first pin and the first bonding terminal, the electrostatic protection circuit connected to the first pin and the electrostatic protection circuit connected to the first bonding terminal jointly bear the invading electrostatic load, the risk of the first pin and the related lines connected to the first pin being damaged is reduced, the electrostatic protection capability of the display module is improved, and the display performance and the touch performance of the display module are ensured. In addition, the technical solution of the present application can connect the idle first bonding terminal in the display module with the first pin of the driving chip, improve the electrostatic protection capability of the display module, and reduce the waste of resources.
