Display Panel Resin Layer for Pressure-Protected Bonding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices face damage due to pressure applied when components are attached to the display panel during the manufacturing process, which can lead to defects and moisture penetration.
Innovation Solution
A display device design that includes a resin layer and cushion layer to protect the display panel, using optical or thermo-curing resins with optional metallic materials, covering the bonding targets to absorb pressure and prevent damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If adhesive layer is used to attach components to display panel with pressurizing process, then components are securely attached, but display panel is damaged due to applied pressure
Solution Approach 1:
The patent introduces a resin layer as an intermediary substance between the bonding target and the display panel. This resin layer absorbs and distributes the pressing force, preventing direct transmission of high pressure to the display panel while maintaining secure attachment through adhesive bonding.
Solution Approach 2:
The resin layer is applied in advance before the bonding target is attached to the display panel. It acts as a cushioning layer that pre-absorbs the pressing force during the attachment process, protecting the display panel from damage before the actual bonding occurs.
2Object-affected harmful factors
If resin layer is applied to cover bonding target, then pressure damage is prevented, but manufacturing process becomes more complex
Solution Approach 1:
The resin layer is applied to cover the entire bonding target uniformly, creating a homogeneous protective layer. This uniform application simplifies the manufacturing process by eliminating the need for complex selective masking or positioning, while still providing comprehensive protection against pressure damage.
3Object-affected harmful factors
If resin layer covers lateral surface of bonding target, then moisture ingress is prevented, but material consumption increases
Solution Approach 1:
The resin layer is applied to cover specific critical areas of the bonding target, particularly the lateral surfaces that are prone to moisture ingress. The application is localized to where protection is most needed, rather than uniformly covering the entire bonding target, thus reducing unnecessary material consumption while maintaining effective moisture protection.

AI summary
A display device includes a display panel including one surface, on which a screen is defined, and an opposing surface located opposite to the one surface, a first bonding target located in a first area of the opposing surface, and a first resin layer located between the first bonding target and the opposing surface and covering at least a portion of a lateral surface of the first bonding target.
