AI Technical Summary

Technical Problem

As foldable display products become thinner and lighter, insufficient battery compartment space leads to battery life failing to meet user needs, and multi-layer flexible circuit boards are costly and have low mechanical strength.

Method used

The flexible circuit board is designed with a projected area of ​​more than 60% of the display area, and the device area is located at the edge of the circuit board. A single-layer or few-layer flexible circuit board is used, combined with a support plate and a buffer layer to increase the battery installation space and improve mechanical strength.

Benefits of technology

By reducing the number of flexible circuit board layers, costs are reduced, battery installation space is increased, battery life is improved, and the mechanical strength of the display module is enhanced.
