AI Technical Summary

Technical Problem

Existing display devices cannot simultaneously accommodate the low impedance of fan-out traces and the narrow bezels of the display device.

Method used

By designing fan-out traces in the fan-out area of ​​the display panel, increasing the width of the outer fan-out traces, and bending part of the second fan-out traces away from the display area, the space occupied on the left and right sides is reduced, thereby reducing the bezel width and lowering the impedance.

Benefits of technology

It achieves a balance between low impedance of the fan-out routing and narrow bezel of the display panel, improving display uniformity and light transmittance.

Abstract

This application provides a display panel and a display device; the display panel reduces the impedance of the outer fan-out trace by increasing the width of the outer fan-out trace, and at the same time, by bending the second part of the second fan-out trace away from the display area, it only occupies the extra space on the left and right sides, thereby reducing the width of the bottom bezel occupied by the second fan-out trace, thus reducing the width of the fan-out area, and taking into account both the low impedance of the fan-out trace and the narrow bezel of the display panel.
