Display Panel Wire Routing for Narrow Bezel Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge is to increase the screen-to-body ratio of display products while maintaining high pixel density, which requires narrowing the bezels and accommodating wires efficiently without compromising display quality.
Innovation Solution
The display panel design includes a first wire in the display area, a second wire extending from the display area to non-display areas, a connection wire in the first non-display area coupling the first and second wires, and a binding pin in the binding area coupled to the second wire, allowing for efficient wire management and narrow bezels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If wires are extended directly from the display area to the binding area, then the bezel width increases, but the wire routing becomes simpler
Solution Approach 1:
The wire routing path is segmented into multiple sections: first wire in display area, second wire in non-display area, and connection wire bridging them. This segmentation allows the wire to be routed through the non-display area to reduce bezel width while maintaining electrical connectivity through structured segments.
Solution Approach 2:
The wire routing transitions from a two-dimensional planar path to a three-dimensional structured path by extending wires into the non-display area and using connection wires with via holes to bridge different layers and regions, effectively utilizing vertical and lateral dimensions to optimize bezel width.
2Area of stationary object
If the non-display area is reduced to achieve narrow bezels, then the screen-to-body ratio increases, but the space for wire routing and pixel arrangement becomes insufficient
Solution Approach 1:
The wire routing function is extracted from the display area and relocated to the non-display area. By taking out the wire routing requirements from the display region and placing them in the non-display region, the invention enables narrow bezels while preserving sufficient space for wire management and pixel density.
3Device complexity
If connection wires are disposed in the display area, then the electrical connection is simpler, but the display quality is affected
Solution Approach 1:
The non-display area serves as an intermediary region that mediates between the display area and the binding area. Connection wires are routed through this intermediary non-display region, eliminating the need for complex in-display routing while preserving display quality by keeping connection structures outside the visible display region.

AI summary
The present disclosure relates to a display panel with a display area, a first non-display area and a second non-display area are correspondingly disposed on opposite sides of the display area in a first direction, and a binding area is disposed on a side of the second non-display area away from the display area. The display panel includes: a first wire, disposed in the display area and extending along the first direction, wherein the first wire is electrically coupled to a plurality of pixels arranged along the first direction; a second wire, extending along the first direction and extending from the display area to the first non-display area, the second non-display area and the binding area; a connection wire, disposed in the first non-display area and coupled between the first wire and the second wire; and a binding pin, disposed in the binding area and coupled to the second wire.
