Flexible Display Divided Wiring Pattern for Transparency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flexible displays face challenges with components directly formed on the base substrate with display pixels, which are fragile due to mechanical and environmental stresses, and require precise design to avoid defects that can lead to complete panel failure under bending stresses.
Innovation Solution
The flexible display incorporates a grid-like strain-reducing trace design with elongated recessed channels and diamond-chain traces to reduce viscid drag and enhance micro-coating layer spread, allowing for increased bending radius and reliability.

Engineering Contradiction Analysis
1Illumination intensity
If a transparent substrate is used to achieve a transparent display device, then transparency is improved, but wiring patterns become visible and deteriorate the transparent state
Solution Approach 1:
The wiring pattern is divided into multiple segments arranged in a matrix configuration. Multiple transparent electrodes are divided into several groups, with each group containing multiple transparent electrode segments. This segmentation allows the wiring to be distributed across the display area, reducing the visibility of individual wiring patterns while maintaining electrical functionality.
Solution Approach 2:
Different regions of the display device have different properties: the pixel region maintains high transparency for display purposes, while the wiring region uses transparent conductive materials with optimized patterns to minimize visibility. The transparent electrode segments are strategically positioned and sized to provide necessary electrical connection while being less visually prominent in the transparent state.
2Illumination intensity
If transparent electrodes are used to maintain transparency, then transparency is improved, but electrical connection between substrates deteriorates
Solution Approach 1:
The transparent electrode is divided into multiple segments arranged in a matrix pattern. Multiple transparent electrodes are segmented into several groups, with each group containing multiple transparent electrode segments. This segmentation creates multiple parallel electrical pathways between substrates, improving overall electrical connection reliability while maintaining transparency through the use of transparent conductive materials.
