Adhesive Layer-Equipped Transparent Plate for Display Bonding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices face difficulties when bonded to glass surfaces, as the bonding process is cumbersome and can result in decreased display quality, and there is a need for improved workability and ease of restoration.
Innovation Solution
An adhesive layer-equipped transparent plate with a first adhesive layer on one surface and a second adhesive layer on the other, both with specific shear moduli and areas, is used to facilitate bonding to a transparent support, ensuring strong interfacial adhesion and easy installation of the display device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a transparent plate with adhesive layer is bonded to a display panel, then display surface protection is improved, but bonding operation becomes troublesome and display quality may decrease
Solution Approach 1:
The adhesive structure is segmented into two distinct adhesive layers: a first adhesive layer on the front surface of the transparent plate and a second adhesive layer on the rear surface. This segmentation allows each layer to perform specific functions - the first layer protects the display surface while the second layer enables bonding to the transparent support, thereby simplifying the overall bonding operation.
Solution Approach 2:
The first adhesive layer is pre-applied to the front surface of the transparent plate before bonding operations. This preliminary action ensures that the display surface is already protected and ready for bonding, eliminating the need for separate protective measures during the bonding process and simplifying operations.
2Strength
If adhesive material is disposed on both surfaces of the transparent plate, then bonding strength is improved, but operation complexity increases
Solution Approach 1:
The two adhesive layers are designed with different local qualities - the first adhesive layer on the front surface has properties optimized for display surface protection, while the second adhesive layer on the rear surface has properties optimized for bonding to the transparent support. This local differentiation allows strong bonding without increasing operational complexity, as each layer is tailored to its specific function.
3Adaptability or versatility
If the display device is bonded to glass wall, then utilization as billboard is improved, but ease of restoration decreases
Solution Approach 1:
The first adhesive layer on the front surface can be selectively removed or extracted without affecting the second adhesive layer that bonds the display device to the glass wall. This extraction capability allows the display device to be restored to its original state or replaced, maintaining ease of restoration while enabling billboard utilization.
