Display Device Diagonal Connection Wires with Protrusion Patterns
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices have inefficiencies in the non-display areas, where signal and connection wires are disposed, leading to dead space and potential issues with light reflection and visibility of spots.
Innovation Solution
The display device incorporates signal wires and connection wires disposed in the display area, with protrusion patterns that overlap touch electrodes, reducing dead space and preventing light reflection and spot visibility.

Engineering Contradiction Analysis
1Area of stationary object
If signal wires and connection wires are disposed in the non-display area, then the display area can be maximized, but dead space is created and light reflection and spot visibility issues occur
Solution Approach 1:
The connection wires are configured to extend in a diagonal direction rather than following conventional horizontal or vertical routing. This diagonal arrangement allows the wires to pass through the display area more efficiently, reducing the dead space created by traditional wire layouts while maintaining electrical connectivity between signal wires and non-display area components.
Solution Approach 2:
Protrusion patterns are added at specific locations along the connection wires where they intersect with touch electrode regions. These localized protrusions block light reflection and spot visibility issues only in the critical areas where touch electrodes are present, while leaving other portions of the display area unaffected and maintaining optimal wire routing elsewhere.
2Ease of manufacture
If connection wires use conventional routing, then manufacturing is simpler, but dead space increases and display quality deteriorates
Solution Approach 1:
The connection wires transition from conventional horizontal/vertical routing to a diagonal configuration. This dimensional change optimizes the use of available space by routing wires through the display area at 45-degree angles, reducing the overall footprint of wire infrastructure and increasing effective display area without significantly complicating the manufacturing process.
3Object-affected harmful factors
If protrusion patterns are added to connection wires, then light reflection and spot visibility are prevented, but device complexity increases
Solution Approach 1:
Rather than modifying the entire connection wire structure, protrusion patterns are applied only at specific locations where touch electrodes are positioned. This localized approach blocks light reflection and spot visibility issues precisely where they occur, while keeping the rest of the wire structure simple and easy to manufacture.
Solution Approach 2:
The connection wire is segmented into distinct portions: diagonal extension sections and protrusion pattern sections. This segmentation allows each portion to be optimized independently - the diagonal sections for space efficiency and the protrusion sections for light reflection prevention - while maintaining overall structural simplicity through modular construction.

AI summary
A display device includes a display panel having a display area and a non-display area, signal wires disposed in the display area, connection wires disposed in the display area and electrically connected to the signal wires, and touch electrodes disposed on the connection wires. The connection wires include diagonal portions extending in a diagonal direction, and first protrusion patterns protruding from the diagonal portions of the connection wires. Parts of the first protrusion patterns overlap the touch electrodes.
