AI Technical Summary

Technical Problem

The lack of heat dissipation design in existing foldable phones leads to high screen temperatures that accelerate adhesive aging, uneven distribution of folding stress causes screen delamination, adhesive overflow pollution affects assembly yield, and electromagnetic shielding relies on additional thickened coatings, limiting the device's thinness and durability.

Method used

The screen uses a graphene conductive barrier to dissipate heat, integrates a pressure-sensitive sensor network to monitor stress distribution, and employs a glue-free design consisting of a transparent double-layer double anti-silicone protective film and a filler layer to achieve bonding of conductive double-sided adhesive, electromagnetic shielding, and circuit conduction, avoiding adhesive contamination.

Benefits of technology

It effectively solves the problems of high-temperature aging and uneven stress distribution of the screen, improves the assembly yield, and realizes the heat dissipation reliability, structural durability and mass production economy of the equipment, thus eliminating the drawbacks of thickening the coating.
