Foldable Display Cover Window with Curved Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing miniaturization of display components in mobile electronic devices leads to a higher occupancy rate, and existing solutions fail to effectively manage the curvature and flexibility of display panels while maintaining protection and usability.
Innovation Solution
A display apparatus with a foldable case, a display panel featuring a substrate with a thin film encapsulation layer, and a cover window system that includes a hard-coated window film and transparent cover windows, which are fixed to the case to cover the curved portions, providing protection and allowing for flexibility and portability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display panel is made curved to enable folding and flexibility, then the device achieves portability and compactness, but the protection and durability of the display panel deteriorates
Solution Approach 1:
The patent applies a flexible display panel with curved surfaces that can be folded while maintaining structural integrity. The thin film encapsulation layer and flexible substrate enable the display to bend and fold without breaking, resolving the contradiction between foldability and protection.
Solution Approach 2:
The display panel is designed with curved surfaces instead of flat surfaces, allowing it to be folded into compact forms. The curvature enables the display to conform to the case shape while maintaining its protective encapsulation layer, achieving both portability and durability.
2Volume of moving object
If the display components are miniaturized to increase occupancy, then the device becomes more compact, but the protection and usability of the display panel deteriorates
Solution Approach 1:
The flexible display panel with thin film encapsulation provides protection despite miniaturization. The flexible structure maintains usability while the thin film layer protects the internal components, resolving the contradiction between compactness and reliability.
3Reliability
If a rigid cover is used to protect the display panel, then the protection improves, but the flexibility and portability deteriorates
Solution Approach 1:
The patent uses a flexible cover window made of transparent material that can bend with the display panel. This flexible cover provides protection while maintaining flexibility, resolving the contradiction between protection and adaptability.
Solution Approach 2:
The cover window is designed to be dynamic rather than static, allowing it to flex and conform to the display panel's shape changes. This dynamic design enables the cover to provide protection during folding and use while maintaining the device's flexibility.

AI summary
A display apparatus includes a case having a foldable portion; a display panel including a first portion on a first side of the case, and a curved portion on a side surface of the case and a second side of the case that is different from the first side; a window film on the first portion of the display panel; and a cover window on the display panel and fixed to the case so as to cover the side surface of the case.
