Display Device Wiring Holes for Bezel Minimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display devices require significant space in the non-display area for indicating line numbers, which limits the minimization of the bezel width and maximization of wiring width, especially in high-resolution displays like UHD where precise identification and repair of defects are necessary.
Innovation Solution
Incorporating holes with edge shapes representing numbers, symbols, and patterns on gate and data wirings in the non-display area, allowing for identification and repair of lines without additional space, thus minimizing the non-display area and maximizing wiring width.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If line numbers are indicated in the non-display area using conventional methods, then line identification is achieved, but the non-display area width increases and bezel width cannot be minimized
Solution Approach 1:
The patent merges the line identification function with the existing gate and data wirings by forming holes directly in these wirings. The holes contain molten material that solidifies to form shapes representing line numbers, symbols, or patterns. This integration eliminates the need for separate identification structures in the non-display area, thereby reducing the required width while maintaining identification capability.
Solution Approach 2:
The patent utilizes optical property changes through molten material filling the holes. The molten material has different optical properties (refractive index, transparency) compared to the surrounding wiring material, creating visible contrast that enables identification of line numbers, symbols, or patterns when light passes through or reflects off the structured wirings.
2Area of stationary object
If the non-display area is minimized, then bezel width is reduced, but space for indicating line numbers and performing repairs is insufficient
Solution Approach 1:
The patent combines multiple functions (line identification, defect marking, repair guidance) into the single structure of the gate and data wirings with integrated holes. The same holes that identify line numbers also serve as markers for defect locations and repair pathways, eliminating the need for separate repair area space.
Solution Approach 2:
The structured wirings with holes serve multiple purposes: identifying gate and data line numbers, marking defect locations, guiding repair processes, and maintaining electrical connectivity. This multi-functionality allows the non-display area to be minimized while preserving all necessary capabilities for identification and repair.
3Reliability
If wiring width is maximized, then signal transmission is improved, but the non-display area width increases
Solution Approach 1:
The patent merges the identification function into the wiring structure itself by creating holes within the gate and data wirings. This integration allows the wirings to maintain their full width for optimal signal transmission while the holes provide identification information, eliminating the need for additional space that would be required if identification and signal transmission were implemented as separate structures.
