Solution Overview
Problem
Foldable display devices face challenges in effectively discharging static electricity, which can lead to defects in thin film transistors and display failures such as green non-uniformity.

The display device incorporates mold frames and brackets made of electrically conductive materials, which are electrically connected to each other, providing a discharge path for static electricity applied to the device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If foldable display devices are designed with compact structures, then the form factor is reduced, but static electricity discharge capability deteriorates
Solution Approach 1:
The patent combines the mold frame and bracket into a single integrated structure made of electrically conductive material. This merging of components creates a continuous conductive path that provides both structural support and static electricity discharge capability, resolving the contradiction between compact form factor and ESD capability
Solution Approach 2:
The mold frame and bracket serve multiple functions: they provide mechanical support for the display panel, enable the folding mechanism, and simultaneously act as conductive pathways for static electricity discharge. This multi-functionality allows the compact structure to maintain both small form factor and reliable ESD capability
2Reliability
If conductive materials are added to provide discharge path, then static electricity discharge capability is improved, but device complexity increases
Solution Approach 1:
By merging the conductive discharge path into the existing mold frame and bracket structure, the patent avoids adding separate conductive components. This integration maintains structural simplicity while providing the required ESD capability
Solution Approach 2:
The mold frame and bracket perform both mechanical functions (support and folding) and electrical functions (static discharge) simultaneously. This multi-functionality eliminates the need for additional dedicated conductive components, thereby reducing overall device complexity
