Tiled Display Panel Layout With Back-Folded Circuit Areas
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing large-size display technologies lack flexibility in accommodating various size requirements for public information displays, as they are limited by rigid structures and inefficient methods for tiling smaller display panels.
Innovation Solution
A tiled display system comprising a transparent rigid mother substrate with a flexible display panel, where the pixel and external circuit areas are strategically located and back-folded through cutting edges, and the edges are passivated to prevent damage, allowing adjacent panels to be tiled securely with an adhesive and optionally framed for stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If rigid display panels are tiled together to form large-size displays, then the structural stability is improved, but the flexibility in accommodating various size requirements deteriorates
Solution Approach 1:
The display system is segmented into multiple smaller display panels that can be tiled together. Each panel maintains structural stability through its rigid construction, while the overall system achieves versatility by allowing flexible arrangement and combination of these segments to create displays of various sizes and configurations.
2Ease of manufacture
If external circuit areas are located outside the transparent rigid mother substrate, then the manufacturing process is simplified, but the circuit areas become vulnerable to damage during folding
Solution Approach 1:
The external circuit areas are positioned outside the transparent rigid mother substrate before the folding process, allowing them to be pre-assembled and protected. The folding action then brings these circuit areas into a protected position where they are secured against the rear surface of the mother substrate, cushioning them from potential damage during subsequent handling and assembly operations.
3Productivity
If cutting edges are used to fold the flexible display panel, then the assembly efficiency is improved, but the cutting edges may cause damage to the circuit areas
Solution Approach 1:
The cutting edges serve as an intermediary element in the folding process. By designing the cutting edges with specific geometric features and positioning them strategically, they enable efficient folding of the flexible display panel while the transparent rigid mother substrate acts as a protective mediator that guides and protects the circuit areas during the folding operation, preventing direct contact between the cutting edges and vulnerable circuit components.
