Display Device Structure for Protecting Slimming Areas From Impact
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices face damage during the slimming process due to physical impact, particularly in the areas where thickness reduction occurs.
Innovation Solution
A display device design with specific non-slimming and slimming portions on both substrates, along with a glass adhesive and reinforcing member, to protect vulnerable areas from physical impact during the slimming process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the display device is made thin and then curved to create a curved display, then the immersive experience is improved, but the slimming areas become vulnerable to physical impact damage
Solution Approach 1:
A protruding portion is formed on the substrate before curving the display panel. This protruding portion acts as a cushioning structure that absorbs and distributes physical impact forces during the slimming process, protecting the thin slimming areas from direct impact damage while allowing the display to maintain its curved shape for immersive viewing experience
2Length of moving object
If etching or polishing processes are performed to reduce thickness before curving, then the display device can be made thin, but the slimming areas are damaged by physical impact during the process
Solution Approach 1:
The protruding portion is formed on the substrate before performing the etching or polishing slimming processes. This preliminary structural preparation creates a protective cushioning element that prevents physical impact damage to the areas being thinned, enabling the thickness reduction process to proceed safely without damaging the vulnerable slimming regions
3Manufacturing precision
If masking members are disposed to prevent damage to conductive patterns during etching, then the circuit portions are protected, but the slimming areas still suffer from physical impact
Solution Approach 1:
The protective function is segmented into two distinct structures: masking members that protect the conductive patterns and circuit portions during etching, and a protruding portion that specifically protects the slimming areas from physical impact. This segmentation allows each structure to perform its specialized protective function without interfering with the other, addressing both types of vulnerability independently
