Display Panel Wiring Segmentation for Size Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display panel manufacturing methods face challenges when adapting to varying panel sizes, as original masks may not be usable, leading to potential wiring disruptions and impaired display functionality.
Innovation Solution
A display panel design featuring a pixel array, first and second wirings, a conductive line, and an insulation layer, where the conductive line is electrically connected to the second wirings to ensure continuous signal transmission, allowing for flexible panel size adjustments by cutting the original panel structure while maintaining display functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display panel size is reduced by cutting the original panel structure, then the manufacturing cost is reduced and manufacturing flexibility is improved, but the wirings may be cut off and the display panel cannot function normally
Solution Approach 1:
The panel structure is divided into functional segments: a first region containing complete first wirings connected to first pixels, and a second region containing second wirings connected to second pixels. This segmentation allows the panel to be cut at specific locations without disrupting the functionality of either region, resolving the contradiction between size adaptability and wiring continuity.
Solution Approach 2:
An insulation layer is introduced as an intermediary element between the first wirings and the second wirings. This insulation layer enables the panel structure to accommodate cuts while maintaining electrical isolation and preventing short circuits, thus preserving reliability while allowing size adaptation through cutting.
2Manufacturing precision
If new masks are generated for each panel size variation, then the manufacturing precision can be maintained, but the manufacturing cost and time increase
Solution Approach 1:
The panel structure is designed with universal features that allow a single mask set to be used across multiple panel sizes. The first region with complete first wirings and the second region with second wirings can accommodate different cutting positions while maintaining consistent manufacturing processes and mask usage, thereby preserving precision while improving productivity.
Solution Approach 2:
The panel structure is pre-configured with regions designed to accommodate future cutting operations. The first wirings are deliberately positioned to remain complete in the first region, and second wirings are positioned in the second region, allowing cuts to be made without requiring new masks or repositioning components, thus maintaining precision while enabling efficient size variation.
3Ease of manufacture
If the display panel is cut to reduce size, then the manufacturing cost decreases, but the display functionality may be impaired due to wiring disruption
Solution Approach 1:
Different regions of the panel are assigned different functional qualities: the first region is designed with complete first wirings for full functionality, while the second region contains second wirings that can accommodate cuts. This local differentiation allows the panel to be cut for cost reduction while preserving display functionality in the first region and maintaining operational capability through the insulated second region.

AI summary
A display panel includes a pixel array, a plurality of first wirings, a plurality of second wirings, a conductive line and an insulation layer. The pixel array includes a plurality of first pixels and a plurality of second pixels. The first wirings are electrically connected to the first pixels, respectively. The second wirings are electrically connected to the second pixels, respectively. The conductive line extends to partially overlap the second wirings and is electrically connected to the second wirings, in which the conductive line is configured to provide a same-color signal to the second pixels. The insulation layer is disposed between the first wirings and the conductive line.
