AI Technical Summary

Technical Problem

Existing flexible LED displays are prone to problems during the rolling and folding process, where the rigid reinforcing sheet can cut through the circuit board, leading to short circuits and affecting the normal use and display of the product.

Method used

A flexible LED display screen is designed, comprising a substrate layer, a conductive layer, a light-emitting layer, and an AB glue encapsulation layer. The substrate layer is made of PI material, and the light-emitting layer is connected to the conductive layer by soldering. A long strip-shaped substrate support strip is attached to the substrate layer. The support strip is made of PI material or steel sheet structure and is located near the outer edge of the substrate layer. It includes an IC module, a main control circuit board, positive and negative electrode charging copper strips, and is covered by an insulating layer to meet the requirements of large-angle bending.

Benefits of technology

This effectively avoids the problem of the wires being cut when bent, improves safety performance, and ensures the normal use and display effect of the display screen.
