AI Technical Summary

Technical Problem

In existing display devices, the organic optical layer and encapsulation layer are susceptible to moisture penetration and foreign matter, which can lead to performance degradation of the light-emitting elements and driving transistors, affecting the stability and lifespan of the device.

Method used

Dam and barrier patterns are set in the non-display area of ​​the display device. Through the electrical connection between multiple lines and the barrier patterns, voltage stability is improved and electromagnetic interference is suppressed, moisture penetration is blocked, and internal components are protected.

Benefits of technology

It effectively blocks moisture penetration, improves the durability of the display device and the uniformity of electrical signals, maintains the performance of the driving circuit and light-emitting elements, optimizes power consumption and reduces electromagnetic interference.
