Display Panel Reinforcement Adhesive for Pressure Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices face defects during the attachment process of the display panel and reinforcing member, which can lead to damage of the circuit elements due to applied pressure.
Innovation Solution
The use of an adhesive member that overlaps the entire non-bending area of the display panel to securely attach the reinforcing member, preventing movement and damage to the panel by distributing pressure evenly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a reinforcing member is attached to the display panel using an adhesive member, then the structural strength and support are improved, but pressure may be concentrated on specific areas causing damage to circuit elements
Solution Approach 1:
The reinforcing member is divided into a bending area portion and a non-bending area portion, with the adhesive member specifically applied to the non-bending area portion. This segmentation allows the adhesive to be positioned where it can effectively distribute pressure without damaging circuit elements in the bending area.
Solution Approach 2:
The adhesive member is applied selectively to the non-bending area portion of the reinforcing member, creating a local quality difference. This ensures that pressure distribution occurs only in the non-bending area, protecting the circuit elements located in the bending area from pressure concentration.
2Reliability
If the adhesive member covers the entire non-bending area, then pressure distribution and panel protection are improved, but the complexity of the attachment process increases
Solution Approach 1:
The attachment process is simplified by segmenting the reinforcing member into bending and non-bending areas, with the adhesive member applied only to the non-bending area. This clear segmentation provides a straightforward guideline for assembly, reducing process complexity while maintaining reliable panel protection.
3Stress or pressure
If the reinforcing member is made larger to increase support area, then the pressure distribution is improved, but the overall device size and weight increase
Solution Approach 1:
The reinforcing member is segmented into bending and non-bending area portions, with the adhesive member applied only to the non-bending area. This allows the reinforcing member to be optimized in size - large enough to provide adequate support area for pressure distribution, but not excessively large to add unnecessary weight.
Solution Approach 2:
The adhesive member is applied locally to the non-bending area portion, creating a focused pressure distribution zone. This local quality approach allows effective pressure distribution without requiring the entire reinforcing member to be oversized, thereby minimizing device weight.

AI summary
A display device includes a window member, a display panel, a first adhesive member, and a reinforcing member. The display panel is disposed below the window member. The first adhesive member is disposed between the window member and the display panel. The first adhesive member overlaps the display panel. The reinforcing member is disposed below the display panel such that the display panel is disposed between the window member and the reinforcing member. On a plane of the window member, a first minimum distance from an outermost portion of the window member to an outermost portion of the display panel is equal to a second minimum distance from the outermost portion of the window member to an outermost portion of the first adhesive member.
