Display Device Lateral Wire Segmentation for Bezel Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices have a significant bezel area that is not utilized for image display, which can reduce the overall efficiency and aesthetics of the device.
Innovation Solution
The display device incorporates a design where first and second lateral wires are strategically positioned on the lateral sides of the substrates, allowing for the reduction of bezel areas by efficiently arranging signal lines and touch signal lines in separate regions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If signal lines and touch signal lines are arranged in the same bezel area, then the connection structure is simpler, but the bezel area becomes larger
Solution Approach 1:
The patent divides the lateral wire arrangement into separate first and second regions on opposite sides of the display panel. First lateral wires connect to first signal lines in the first region, while second lateral wires connect to second signal lines in the second region. This segmentation allows independent optimization of each region, reducing the overall bezel area while maintaining manageable complexity through modular organization.
Solution Approach 2:
The patent utilizes the lateral dimension of the display panel by positioning first and second lateral wires on opposite lateral sides rather than concentrating all connections in a single bezel area. This dimensional distribution spreads out the connection points, reducing the required bezel width while organizing wires into distinct spatial groups that are easier to manage.
2Area of stationary object
If lateral wires are concentrated in a single region, then the connection structure is simpler, but the bezel area increases
Solution Approach 1:
The manufacturing process is segmented into separate steps for connecting first lateral wires to first signal lines and second lateral wires to second signal lines. This segmentation allows specialized manufacturing techniques to be applied to each region independently, reducing bezel area while maintaining manufacturing ease through standardized repetitive processes in each region.
Solution Approach 2:
The patent implements separate connection structures for first and second lateral wires, which may appear excessive compared to a single unified connection. However, this partial separation in different lateral regions actually simplifies the manufacturing of each individual connection zone while reducing the overall bezel area, as each region can be optimized for its specific wiring requirements.

AI summary
A display device includes: a first substrate; a second substrate; first signal lines on the first substrate; second signal lines on the second substrate; first lateral wires on a lateral side of a first edge of the first substrate, and connected to end portions of the first signal lines; and second lateral wires on a lateral side of a second edge of the second substrate, and connected to end portions of the second signal lines. The first and second lateral wires are located in at least one first region and at least one second region, the at least one first region and the at least one second region being spaced from each other on the lateral sides of the first substrate and the second substrate. The at least one first region includes the first lateral wires, and the at least one second region includes the second lateral wires.
