Display Bezel Adhesive Structure for Less Visible Bonded Edges
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices have noticeable bonded portions where the bezel and front plate are joined with an adhesive, affecting the aesthetic harmony when the display is off.
Innovation Solution
The display device incorporates an adhesive member with a first adhesive layer partially contacting the front plate, featuring spaces or recessed portions, and optionally a second adhesive layer on the bezel side, to minimize visibility of the bonded area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If an adhesive member is used to bond the bezel and front plate, then the structural connection is achieved, but the bonded portion becomes noticeable and affects aesthetic harmony
Solution Approach 1:
The adhesive member is designed with non-uniform thickness, featuring a thinned portion at the bonding interface and a thicker portion at the bezel side. This local variation in thickness creates different optical properties at different locations, allowing the adhesive layer to be less visible from the front while maintaining adequate bonding strength.
Solution Approach 2:
The adhesive member's thickness parameter is varied across different regions. By controlling the thickness to be smaller at the front plate interface and larger at the bezel interface, the design optimizes both aesthetic appearance (reducing visibility of the adhesive) and structural performance (maintaining bonding strength).
2Strength
If the adhesive layer fully contacts the front plate, then bonding strength is maximized, but the visible area of the bonded portion increases
Solution Approach 1:
The adhesive member is segmented into functionally distinct portions: a thinned portion at the front plate interface that minimizes visibility, and a thicker portion at the bezel interface that provides structural support and bonding strength. This segmentation allows each region to optimize its specific function without compromising the other.
