Display Panel Flattening Assembly With Corner Tension Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ultra-thin display panels face challenges in maintaining shape retention due to weak structural integrity, leading to potential deformation and visibility issues when using full-surface adhesive components, and partial-area adhesives struggle to maintain flatness effectively.
Innovation Solution
A panel flattening assembly is attached to the rear surface of the display panel, featuring fixing assemblies at corners with displacement adjusting members, such as screws and supporting members, to apply tension and maintain flatness while minimizing the area of attachment, thus reducing surface roughness impact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If full-surface adhesive components are used to maintain shape, then shape retention is improved, but surface roughness and visibility issues worsen
Solution Approach 1:
The adhesive application area is segmented from full-surface to corner-specific locations. The panel flattening assembly applies adhesive only at corner regions rather than across the entire panel back surface, thereby maintaining shape retention while minimizing surface roughness and visibility issues.
Solution Approach 2:
The flattening assembly provides localized shape support at critical corner regions rather than uniform support across the entire panel. This concentrates the stabilizing function where it is most needed (at corners which are prone to deformation) while leaving the central display area smooth and visible.
2Length of stationary object
If ultra-thin substrate is used to reduce thickness, then device thickness is reduced, but shape retaining force deteriorates
Solution Approach 1:
The panel flattening assembly is pre-configured with corner-specific adhesive application and tensioning mechanisms before panel assembly. This preliminary preparation ensures that shape retention is established at the most critical locations (corners) before the ultra-thin panel is installed, compensating for the inherent weakness of thin substrates.
Solution Approach 2:
The flattening assembly acts as a counterbalancing structure that provides opposing support force to counteract the deformation tendencies of the ultra-thin panel. By positioning support elements at corners and using tensioning members, the assembly creates stabilizing forces that compensate for the reduced shape retaining force of the thin substrate.
3Object-affected harmful factors
If partial-area adhesive is used to reduce surface roughness, then visibility is improved, but flatness maintenance deteriorates
Solution Approach 1:
The adhesive application is segmented to corner-specific locations rather than continuous or broad-area application. This segmentation maintains visibility by limiting adhesive exposure to minimal corner regions while preserving flatness through strategic placement at structurally critical corner positions.
Solution Approach 2:
The flattening assembly provides localized flatness control at corner regions where adhesive application has the maximum structural impact. This local quality approach ensures that visible central areas remain adhesive-free and smooth, while corner regions receive concentrated adhesive support to maintain overall panel flatness.
