Flexible Display Cover Plate With Layered Impact Absorption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current flexible display cover plates made of thin films or ultra-thin glass provide inadequate protection against external forces due to low thickness and fragility, leading to insufficient buffer effect and poor rigidness, which can result in damage to the display substrate.
Innovation Solution
A flexible display cover plate design incorporating a first cover-plate layer and at least one auxiliary protective layer, including a bonding layer with a modulus of 0.2 MPa, which absorbs and diffuses impact, and may include ultra-thin glass or flexible thin films with protective coatings, to enhance protection and rigidity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the thickness of the transparent thin film or ultra-thin glass is reduced to enable flexibility and foldability, then the deformable and foldable properties are improved, but the buffer effect and protection effect against external force deteriorate
Solution Approach 1:
The cover plate is divided into multiple layers: a first cover-plate layer (transparent thin film or ultra-thin glass) that provides flexibility and foldability, and a second cover-plate layer (rigid plate) that provides strength and protection. This segmentation allows each layer to perform its specific function optimally without compromising the other.
Solution Approach 2:
The invention uses a composite structure combining flexible materials (transparent thin film or ultra-thin glass) with rigid materials (rigid plate). This composite material approach enables the cover plate to simultaneously achieve both flexibility for folding and rigidity for protection against external forces.
2Adaptability or versatility
If the thickness of the transparent thin film is reduced to less than 0.1 mm to maintain flexibility, then the foldability is improved, but the buffer effect when receiving external force deteriorates
Solution Approach 1:
The cover plate is divided into multiple layers: a first cover-plate layer (transparent thin film or ultra-thin glass) that provides flexibility and foldability, and a second cover-plate layer (rigid plate) that provides strength and protection. This segmentation allows each layer to perform its specific function optimally without the other.
Solution Approach 2:
The invention uses a composite structure combining flexible materials (transparent thin film or ultra-thin glass) with rigid materials (rigid plate). This composite material approach enables the cover plate to simultaneously achieve both flexibility for folding and rigidity for protection against external forces.
3Adaptability or versatility
If the thickness of the ultra-thin glass is reduced to less than 0.1 mm to maintain flexibility, then the foldability is improved, but the fragility increases making it prone to damage
Solution Approach 1:
The cover plate is divided into multiple layers: a first cover-plate layer (transparent thin film or ultra-thin glass) that provides flexibility and foldability, and a second cover-plate layer (rigid plate) that provides strength and protection. This segmentation allows each layer to perform its specific function optimally without the other.
Solution Approach 2:
The invention uses a composite structure combining flexible materials (transparent thin film or ultra-thin glass) with rigid materials (rigid plate). This composite material approach enables the cover plate to simultaneously achieve both flexibility for folding and rigidity for protection against external forces.

AI summary
This application relates to a flexible display cover plate, a display panel, and a display apparatus, and relates to a field of display technologies. The flexible display cover plate includes a first cover-plate layer and at least one auxiliary protective layer that is disposed on a face of the first cover-plate layer. The auxiliary protective layer includes a bonding layer and a second cover-plate layer that are superimposed along a direction away from the first cover-plate layer. The bonding layer is a deformable film layer, and a face that is of an outermost second cover-plate layer in the at least one auxiliary protective layer and that is away from the bonding layer is used to attach to a display substrate. When the flexible display cover plate receives external force, both the first cover-plate layer and the auxiliary protective layer can absorb and diffuse impact of the external force, so that the external force received by the display substrate is reduced, and damage caused by the external force to the display substrate is reduced, thereby improving a protection effect provided for the display substrate. This application is used to improve the protection effect provided for the display substrate.
