Flexible Display Slim Bezel via Substrate Hole Wiring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional flexible display apparatuses are limited in maximizing display area due to the space occupied by the bezel around the perimeter, which restricts the implementation of a larger display area.
Innovation Solution
A flexible display apparatus design featuring a slim bezel is achieved by incorporating a flexible substrate with distinct areas, where the first and second areas have holes for wiring that penetrate the substrate, and the third area is bent to facilitate electrical connection between these wirings without occupying additional space, allowing for a slimmer bezel and increased display area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If a conventional flexible display apparatus uses a bezel around the periphery of the display area, then the structural integrity and wiring routing are maintained, but the display area cannot be maximized due to the space occupied by the bezel
Solution Approach 1:
The patent extracts the function of the bezel from the display structure by routing wirings through holes in the flexible substrate instead of through a separate bezel structure. This eliminates the need for a traditional bezel while maintaining wiring functionality, thereby maximizing the display area.
Solution Approach 2:
The patent transitions the wiring routing from a planar arrangement (requiring bezel space) to a three-dimensional arrangement by passing wirings through holes that penetrate the flexible substrate. This allows wirings to be positioned in the thickness direction rather than occupying peripheral display area.
2Area of moving object
If the flexible substrate is bent in the third area to connect first and second areas, then electrical connectivity is achieved with reduced bezel space, but manufacturing precision becomes more difficult due to the bending process
Solution Approach 1:
The patent forms holes in the flexible substrate at predetermined positions before the bending process. This preliminary action ensures that when the substrate is bent, the holes in the first and second areas align properly to establish electrical connectivity, thereby maintaining manufacturing precision despite the subsequent bending operation.
3Area of moving object
If wirings are routed through holes in the flexible substrate, then bezel space is eliminated and display area is maximized, but the complexity of wiring embedding and connection increases
Solution Approach 1:
The patent embeds wirings inside holes of the flexible substrate, nesting the wiring structure within the substrate thickness rather than placing it on the surface. This nesting approach eliminates the need for additional bezel space while integrating the wiring structure into the substrate itself, simplifying the overall manufacturing process.
