Display Device Layer Integration for Bending-Region Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices face challenges with dead space and require complex manufacturing processes, particularly in flexible or foldable designs where additional components and structures complicate the production and functionality.
Innovation Solution
A display device design incorporating a display panel with a first and second region, a bending region, an anti-reflection layer, and a shock absorbing layer with a thickness of 50-80 μm, along with a cover layer and protective patterns, to minimize dead space and simplify manufacturing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a shock absorbing layer is added to protect the bending region, then the reliability is improved, but the device complexity increases
Solution Approach 1:
The patent combines the shock absorbing layer with the anti-reflection layer into a single integrated structure. The anti-reflection layer serves dual purposes: reducing light reflection and providing shock absorption protection to the bending region, thereby eliminating the need for a separate shock absorbing layer and reducing device complexity
Solution Approach 2:
The anti-reflection layer is designed to perform multiple functions simultaneously: optical function (reducing reflection) and mechanical protection function (absorbing shock in the bending region). This multi-functionality reduces the total number of components while improving reliability
2Reliability
If the shock absorbing layer overlaps the first region and bending region, then the reliability is improved, but the area of the display device increases
Solution Approach 1:
The patent applies different properties to different regions: the anti-reflection layer has shock-absorbing properties specifically in the bending region while maintaining its optical properties in the first region. This localized functionality provides protection where needed without expanding the overall device area
Solution Approach 2:
By merging the shock absorbing function into the existing anti-reflection layer, the patent avoids adding extra layers that would increase dead space, while still providing comprehensive protection to both the first region and bending region

AI summary
A display device includes a display panel having a first region, a second region, and a bending region which is between the first region and the second region and at which the display panel is bendable, an anti-reflection layer on the display panel and including a color filter, and a shock absorbing layer facing the display panel with the anti-reflection layer therebetween. The shock absorbing layer extends from the first region of the display panel and into the bending region thereof.
