AI Technical Summary

Technical Problem

Existing display devices have shortcomings in terms of external light reflection, line load, transistor optical reliability and thermal stability. In particular, in organic light-emitting display devices, external light reflection is more obvious, which affects the display effect and component life.

Method used

A transmission reduction layer is introduced into the display device. This layer is disposed between the metal layer and the substrate and has a black uneven shape on the surface to reduce the reflection of external light. At the same time, the transmission reduction layer is placed in the area where the line load increases to reduce resistance and improve the optical reliability and thermal stability of the transistor.

Benefits of technology

It effectively reduces external light reflection, lowers line load, improves the optical reliability and thermal stability of transistors, and enhances the overall performance of the display device.
