Display Panel Wire Layout for Narrow-Bezel Data Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices have wide borders due to the arrangement of wires connecting multiplexers and drive chips, which contradicts the trend towards narrower borders.
Innovation Solution
The display panel design includes a border area with a chip binding area where data pins are arranged, and multiplexers are placed along the curved edge of the active area, with data transfer wires passing through the active area to reduce the occupied space and narrow the border area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If wires connecting multiplexers and drive chip are arranged in the inactive area, then data signal transmission is achieved, but the border area becomes wide
Solution Approach 1:
The patent changes the routing dimension by having data transfer wires pass through the active area rather than being confined to the inactive area. This dimensional shift in wire arrangement allows the border area to be narrowed while still achieving the necessary data signal transmission between multiplexers and drive chip.
Solution Approach 2:
Instead of the conventional approach where wires are arranged in the inactive area, the patent inverts the arrangement by routing wires through the active area. This inversion resolves the contradiction by reducing border area width while maintaining functional connectivity.
2Device complexity
If multiplexers are arranged along the curved edge of the active area, then data signal routing is simplified, but more wire space is needed in the border area
Solution Approach 1:
The patent resolves this contradiction by routing data transfer wires through the active area (dimensional change) rather than confining them to the border area. This allows multiplexers to be arranged along the curved edge for simplified routing while the wires pass through the active area to reach data pins, preventing border area expansion.
3Area of stationary object
If data transfer wires pass through the active area, then the border area is narrowed, but the active area is occupied by additional wires
Solution Approach 1:
The patent inverts the conventional wire routing approach by passing data transfer wires through the active area instead of the inactive area. This inversion narrows the border area as the primary benefit, while the occupation of active area by wires is accepted as a necessary trade-off to achieve narrower borders.

AI summary
A display panel and a display device are provided. Data transfer wires electrically connected to first multiplexers pass through an active area and are electrically connected to data pins arranged in a chip binding area. Therefore, an area occupied by the data transfer wires in the border area is reduced, a space for wiring in the border area can be vacated and the border area can be narrowed. This follows the trend towards increasingly narrow borders of display devices.
