AI Technical Summary

Technical Problem

The trend towards thinner and lighter electronic devices has led to limited battery space. Existing ribbon circuit boards take up a lot of space, which affects battery capacity.

Method used

The ribbon cable circuit board is bonded to the encapsulation part that is bent to the back of the light-emitting surface of the display panel, and the ribbon cable circuit board is located between the two ends of the encapsulation part. A multi-layer circuit board structure is adopted, combined with flexible bonding circuit board and waterproof adhesive protection, to optimize the wiring and waterproof design.

Benefits of technology

It reduces the size occupied by the ribbon cable circuit board, increases battery capacity, increases wiring area, improves space utilization, and provides a variety of layout methods and waterproof solutions to enhance the reliability of electronic devices.
