Curved Display Assembly via Flat Substrate Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The difficulty in achieving uniformity and ease of assembly during the attachment process of curved-surface display screens, particularly due to challenges in controlling the flexible display panel during the curved-surface attaching process.
Innovation Solution
A method involving the attachment of a flexible display panel to flexible glass to form an integral body, which is then mounted into a frame with a perimeter less than that of the integral body, using a laminating or rolling conveying attaching manner, and incorporating an annular groove in the frame for secure embedding, replacing the need for preformed bent glass and curved-surface attaching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If curved-surface attaching process is used to assemble curved-surface display screen, then the display screen can achieve curved surface shape, but the uniformity of flexible display panel attachment cannot be controlled and the attaching process becomes highly difficult
Solution Approach 1:
The patent applies preliminary action by first attaching the flexible display panel to a flat rigid substrate to form an integral body before mounting it into the frame. This preliminary attachment on a flat surface ensures uniformity and ease of assembly, avoiding the difficulties of curved-surface attaching. The curved surface shape is then achieved by the frame constraint rather than during the attachment process itself.
2Shape
If curved-surface attaching process is used, then curved surface shape can be achieved, but the attaching process becomes highly difficult requiring specialized equipment
Solution Approach 1:
The patent performs the attachment operation preliminarily on a flat rigid substrate before final assembly into the frame. This approach converts a difficult curved-surface attaching operation into a simple flat-surface attachment, dramatically improving ease of manufacture and eliminating the need for specialized curved-surface attaching equipment.
Solution Approach 2:
Instead of attaching the flexible display panel directly to the curved frame surface (the conventional difficult approach), the patent inverts the sequence by first attaching it to a flat substrate and then mounting the entire assembly into the frame. This inversion transforms an intractable curved-surface attaching problem into a simple flat-surface attachment followed by straightforward frame installation.
3Shape
If flexible display panel is attached during curved-surface attaching process, then curved display can be formed, but uniformity control becomes difficult
Solution Approach 1:
The patent performs the attachment of the flexible display panel to a flat rigid substrate as a preliminary step before final frame assembly. This preliminary action on a stable flat surface ensures uniform attachment and stable composition, while the curved display shape is subsequently achieved through the frame constraint rather than during the attachment process.

AI summary
A method for assembling a curved-surface display screen includes: attaching a flexible display panel to a flexible glass to form an integral body; and mounting the integral body into a frame. The frame surrounds a periphery of the integral body, and a perimeter of the frame is less than that of the integral body.
