Display Panel Hollow Area Data Line Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge is to enhance the screen-to-body ratio of display panels while minimizing the impact of non-display holes on data line transmission, which currently requires winding data lines around the holes, increasing the non-display area and reducing the screen-to-body ratio.
Innovation Solution
The display panel incorporates a hollow area with switch units that connect data lines across the hollow area, allowing for efficient data signal transmission without winding, thereby reducing the border width and maintaining a high screen-to-body ratio.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data lines are wound around the periphery of the non-display hole to ensure normal data signal transmission, then data signal transmission is ensured, but the area of the non-display area increases, which reduces the screen-to-body ratio
Solution Approach 1:
The display area is segmented into three separate display areas (first, second, and third display areas) by the hollow area. Data lines are separately arranged in each display area, with first data lines in the first display area, second data lines in the second display area, and third data lines in the third display area. This segmentation eliminates the need to wind data lines around the hollow area, reducing the non-display area while ensuring data signal transmission to each segment.
Solution Approach 2:
Switch units are introduced as intermediary components to connect data lines across the hollow area. The switch units enable the first data lines to connect to the second data lines, and the second data lines to connect to the third data lines, facilitating data signal transmission without requiring data lines to physically wind around the hollow area perimeter.
2Area of stationary object
If the display area is divided into multiple separate areas by a hollow area, then the screen-to-body ratio is increased, but data line routing becomes more complex requiring switch units
Solution Approach 1:
Switch units are used to dynamically control data line connections between different display areas. The switch units can be selectively activated to connect or disconnect data line pathways, enabling flexible data routing adaptation based on display requirements while maintaining a simplified physical layout compared to winding data lines around the hollow area.
3Area of stationary object
If a hollow area is introduced in the display area to increase screen-to-body ratio, then the visual effect is improved, but data lines are cut off requiring complex wiring solutions
Solution Approach 1:
The display area is divided into three independent display areas with separately arranged data lines. This segmentation allows data lines to be directly routed to each display area without needing to wrap around the hollow area, significantly simplifying the manufacturing process and data line wiring compared to conventional approaches.
Solution Approach 2:
Switch units serve as intermediary components that simplify data line connections across the hollow area. Rather than requiring complex winding routing, the switch units provide straightforward connection points that ease the manufacturing process while maintaining functional integrity.

AI summary
A display panel has a display area and a non-display area surrounding the display area. The display area has a first side and a second side opposite to the first side, and includes: a hollow area having first and second edges; and first to third display areas. The display panel includes: a driving chip arranged in the non-display area closer to the first side than to the second side; first data lines arranged in the first display area; second data lines arranged in the second display area; and third data lines arranged in the third display area. The first edge is closer to the driving chip than the second edge. At least one or more of the first data lines is connected to corresponding one or more of the second data lines through a switch unit.
