Display Panel Auxiliary Lines for Signal Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing display panel designs face challenges in optimizing the screen ratio and user experience due to the large area occupied by functional components, which interrupts signal lines and reduces the display area, leading to insufficient space for displaying information and aesthetic issues.
Innovation Solution
The display panel incorporates a non-display area with different sized regions surrounding the display area, using auxiliary lines to connect interrupted signal lines within the display area, thereby reducing the non-display area and improving space utilization and aesthetics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If functional components are arranged in a large opening at the front-facing side, then user experience is improved, but the display area is reduced and signal lines are interrupted
Solution Approach 1:
The non-display area is divided into a first non-display area and a second non-display area with different areas. This segmentation allows for optimized arrangement of functional components while minimizing the impact on the display area and enabling differentiated signal line routing strategies for different regions.
Solution Approach 2:
Different regions of the non-display area are assigned different functions and characteristics. The first non-display area (larger) and second non-display area (smaller) have different signal line configurations, with type-A and type-B signal lines respectively, allowing each region to be optimized for its specific functional requirements.
2Device complexity
If signal lines are routed through the non-display area, then wiring is simplified, but the non-display area occupies more space
Solution Approach 1:
Signal lines are routed through the non-display area in the horizontal plane, utilizing the available space in this dimension. By configuring different types of signal lines (type-A and type-B) to pass through different non-display areas, the routing complexity is managed while minimizing the vertical space occupation.
Solution Approach 2:
The first non-display area and second non-display area are designed with asymmetric areas, where the first non-display area is larger than the second non-display area. This asymmetric configuration allows for optimized signal line routing, with type-A signal lines routed through the larger first non-display area and type-B signal lines through the smaller second non-display area, balancing wiring simplicity with space efficiency.

AI summary
The present disclosure provides a display panel and a display device. The display panel has a non-display area and a display area surrounding the non-display area, and the non-display area includes a first non-display area and a second non-display area having different areas. The display panel includes type-A signal lines interrupted by the first non-display area and the type-B signal lines interrupted by the second non-display area. A first auxiliary line electrically connects the first type-A signal sub-line and the second type-A signal sub-line disconnected, and a second auxiliary line electrically connects the first type-B signal sub-line and the second type-B signal sub-line disconnected. The first auxiliary line includes a first portion located in the display area, and the second auxiliary line includes a second portion located in the display area. The number of the first auxiliary lines is larger than that of the second auxiliary lines.
