AI Technical Summary
Technical Problem
The existing manufacturing process for flexible display substrates is complex, involving multiple patterning steps, resulting in high manufacturing time and costs.
Method used
The signal traces are separated into a first trace area and a second trace area, and are electrically connected through signal connection lines in the bend area. The signal connection lines are located on different layers and are formed using the first metal layer and/or the second metal layer, which reduces the number of patterning processes.
Benefits of technology
This reduces the manufacturing time and cost of flexible display substrates while maintaining the reliability of electrical connections and the narrow bezel design of flexible display devices.
