Foldable Display Support Structure for Concealed Adhesive Layers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Adhesive layers used to adhere wing plates to support plates in flexible display devices can be visually noticeable, detracting from the aesthetic appeal and user experience.
Innovation Solution
The display device incorporates specific configurations of adhesive layers and support plates with varying widths and thicknesses to ensure that wing plates and sub-wing plates overlap only in certain areas when folded, thereby concealing these layers from view.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If adhesive layers are used to adhere wing plates to support plates, then the structural integrity and assembly are ensured, but the adhesive layers become visually noticeable and detract from aesthetic appeal
Solution Approach 1:
The patent applies dimensionality change by configuring the adhesive layers to have varying thicknesses in the vertical dimension. The first adhesive layer has a first thickness and the second adhesive layer has a second thickness that is greater than the first thickness. This dimensional variation allows the adhesive layers to be positioned at different depths, enabling them to overlap when the folding part is bent, thereby concealing them from visual detection and resolving the aesthetic appearance issue while maintaining assembly functionality.
2Adaptability or versatility
If the display device is made foldable with a folding part, then flexibility and portability are improved, but adhesive layers may become visible when folded
Solution Approach 1:
The patent utilizes dimensional variation in adhesive layer thickness to solve the visibility problem when the display device is folded. By configuring the second adhesive layer to have a greater thickness than the first adhesive layer, the adhesive layers are positioned at different vertical levels. When the folding part is bent, these layers overlap in the vertical dimension, concealing them from visual detection and maintaining aesthetic appearance while preserving folding adaptability.
Solution Approach 2:
The patent applies the nesting principle by having the first and second adhesive layers overlap when the folding part is bent. The varying thicknesses create a nested configuration where the thinner first adhesive layer is positioned within the vertical space occupied by the thicker second adhesive layer, causing them to overlap and mutually conceal each other from external view, thus resolving the visibility issue while maintaining folding functionality.

AI summary
A display device includes: a display module; a first support plate below the display module, and including a first non-folding part and a folding part along a first direction; a first flat plate below the first non-folding part; a first wing plate below the folding part, and adjacent to the first flat plate in the first direction; and a first sub-wing plate between the folding part and the first wing plate. The first wing plate has a width greater than that of the first sub-wing plate in the first direction.
