Display Panel Bezel Wiring Layout for Narrow 8K Sealant Curing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
8K display products face challenges with narrow bezels and high requirements for aperture ratio and conductivity, leading to incomplete sealant curing and uneven brightness due to conventional gate drive circuit wiring designs that are not suitable for small-sized products with limited space and high via hole requirements.
Innovation Solution
The display panel design includes a bezel region with first and second wires arranged side by side, connected via first and second via holes, and a transparent conductive block, allowing for efficient space utilization in the second direction, reducing space in the first direction, and ensuring adequate aperture ratios for complete sealant curing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If sealant is placed directly on buslines of gate drive circuits to save space, then the bezel width is reduced, but the aperture ratio becomes insufficient causing incomplete sealant curing and mura
Solution Approach 1:
The patent changes the wiring arrangement from conventional horizontal layout to a layout that充分利用 the second direction (vertical direction in bezel region). First wires and second wires are arranged side by side along the second direction, with via holes distributed in both first and second directions. This dimensional optimization allows adequate aperture ratio while maintaining narrow bezel width.
2Manufacturing precision
If conventional wiring design with sufficient vertical space is used, then the aperture ratio is adequate for sealant curing, but the space in horizontal direction is wasted and it is not suitable for 8K products with small sizes
Solution Approach 1:
The patent optimizes the wiring layout to fully utilize the second direction (vertical direction) by arranging first wires and second wires side by side, and distributing via holes in both first and second directions. This allows adequate aperture ratio while minimizing horizontal space occupation, making it suitable for narrow bezel 8K displays.
Solution Approach 2:
The patent changes the arrangement parameters of wires and via holes. First wires extend along first direction and are arranged side by side along second direction. Second wires similarly extend along first direction and are arranged side by side along second direction. Via holes are distributed in both directions to ensure adequate aperture ratio and conductivity.
3Reliability
If the number of via holes is reduced to simplify manufacturing, then the conductivity requirement is not met, but increasing via holes complicates the structure
Solution Approach 1:
The patent segments the connection path into multiple via holes distributed in both first and second directions. First via holes connect first wires to transparent conductive block, and second via holes connect second wires to transparent conductive block. This segmentation ensures adequate conductivity while maintaining manageable structural complexity.

AI summary
A display panel is provided. At least two first wires in a second direction are electrically connected to each other and at least two second wires in the second direction are electrically connected to each other. The space in the second direction is fully used to arrange the first wires and the second wires to ensure the number of first via holes disposed corresponding to the first wires and the number of second via holes disposed corresponding to the second wire, thereby ensuring the connectivity of a transparent conductive block that bridges the first wires and the second wires through the first via holes and the second via holes.
