Flexible Display Buffer Structure for Deformation Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flexible displays with protrusions and recesses on their rear surface or between layers can lead to deformation of the display panel, resulting in quality deterioration and reduced resolution due to the deformation caused by these structural features.
Innovation Solution
A flexible display assembly is designed with a buffer layer that includes projections inserted into the valleys of the protrusions and recesses, and a support layer to absorb or relieve these deformations, preventing the transfer of deformation to the display panel and maintaining the display's quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If functional structures with protrusions and recesses are added to the flexible display assembly, then the functionality and structural support are improved, but the display quality and resolution deteriorate due to deformation transfer
Solution Approach 1:
A buffer layer is introduced as an intermediary component between the functional structures (with protrusions and recesses) and the display panel. This buffer layer absorbs and relieves the deformation caused by protrusions and recesses, preventing it from transferring to the display panel, thus maintaining display quality while allowing functional structures to be present
Solution Approach 2:
The buffer layer is positioned in advance between the functional structures and the display panel to cushion and absorb potential deformation before it can affect the display quality. This preventive measure ensures that the display panel remains unaffected by the structural irregularities of underlying layers
2Strength
If layers are pressed by protrusions and recesses to implement functional structures, then the structural support is improved, but the display panel deforms and surface pattern is distorted
Solution Approach 1:
The buffer layer serves as a mediator that absorbs the pressing force from protrusions and recesses, preventing this force from deforming the display panel and distorting its surface pattern, while still allowing the functional structures to maintain their structural support function
Solution Approach 2:
The buffer layer changes the mechanical parameters (such as pressure distribution and deformation characteristics) between the functional structures and the display panel, converting the concentrated pressing force into distributed stress that does not cause visible deformation on the display surface
