Flexible Double-Sided Display Assembly Without Rigid Support Plates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional double-sided display screens are thick and lack flexibility, making them unsuitable for modern thinness and flexibility trends.
Innovation Solution
A manufacturing method for a flexible double-sided display screen involves attaching two display devices with support plates, stripping off the first support plates to expose flexible substrates, and then removing the second support plates, allowing the flexible substrates to be attached together, resulting in a flexible structure without the need for rigid support plates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If two display screens are attached together to form a double-sided display screen, then double-sided display function is achieved, but the thickness increases and flexibility is lost
Solution Approach 1:
The patent uses flexible substrates as the core component to replace traditional rigid support structures. The flexible substrate allows the display screen to be bent and folded while maintaining structural integrity, thereby achieving both double-sided display functionality and flexibility/thinness requirements simultaneously.
2Adaptability or versatility
If two display screens are attached together to form a double-sided display screen, then double-sided display function is achieved, but the manufacturing cost increases
Solution Approach 1:
The patent merges the support function and the flexible substrate function into a single integrated flexible substrate structure. This eliminates the need for separate rigid support plates that would need to be attached and detached during manufacturing, thereby simplifying the manufacturing process and reducing costs while achieving double-sided display.
3Stability of the object's composition
If rigid support plates are used during manufacturing, then structural stability is improved, but flexibility of the final product is reduced
Solution Approach 1:
The patent employs temporary support plates during the manufacturing process to provide structural stability for precise assembly operations. After the flexible substrate is properly attached and positioned, the temporary support plates are removed, allowing the final product to achieve its flexible form without rigid supports.
Solution Approach 2:
The temporary support plates serve as intermediary elements during manufacturing only. They facilitate the attachment process by providing a stable base, but are deliberately designed to be removable so they do not become part of the final product, thus mediating between manufacturing stability requirements and final product flexibility.

AI summary
A flexible double-sided display screen and a manufacturing method thereof are provided. The flexible double-sided display screen can be manufactured by the manufacturing method of the flexible double-sided display screen: by attaching two second support plates onto encapsulation layers of two display devices, respectively, then stripping off first support plates of the two display devices to expose flexible substrates thereof, thereby rigid second support plates being able to support the two display devices to conveniently attach the flexible substrates of the two display devices together, and at last, stripping off the two second support plates of the two display devices. The flexible double-sided display screen does not have the first support plates and second support plates, thereby having flexibility, and a thickness and costs of the flexible double-sided display screen can be reduced.
