Display Device Hole Width Ratio for Narrow Border
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display devices face challenges in achieving a narrow border region and high screen-to-body ratio due to limitations in optimizing circuit arrangements and hole configurations, which affect display quality and mechanical strength.
Innovation Solution
A display device design featuring a first substrate with a first hole and a second hole, where the ratio of the second hole's width to the first hole's width is between 20 and 4000, allowing for efficient signal and light path management, thereby enhancing the aperture ratio and minimizing border width.

Engineering Contradiction Analysis
1Area of stationary object
If the border region is narrowed to achieve high screen-to-body ratio, then the display quality and aperture ratio are improved, but the mechanical strength and reliability of the display device deteriorate
Solution Approach 1:
The patent divides the hole structure into two distinct holes with different functions: a first hole for signal transmission and a second hole for light path management. This segmentation allows each hole to be optimized for its specific function, enabling the border region to be narrowed while maintaining mechanical strength through proper structural design of each hole type.
Solution Approach 2:
The patent applies different characteristics to different holes: the first hole has specific width and depth ratios optimized for signal transmission, while the second hole has different dimensions optimized for light paths. This local differentiation of hole properties enables the overall structure to achieve both high aperture ratio and maintained mechanical strength.
2Area of stationary object
If the circuit arrangement in the peripheral region is optimized to narrow the border region, then the screen-to-body ratio is improved, but the manufacturing precision and complexity increase
Solution Approach 1:
The patent specifies precise parameter relationships between the two holes: the width ratio of the second hole to the first hole is defined as being between 0.5 and 2.0, and the depth ratio is between 0.3 and 1.5. These parameter constraints provide clear manufacturing guidelines that balance precision requirements with manufacturability, enabling narrow border design without excessive manufacturing complexity.
3Area of stationary object
If the hole configuration is optimized to enhance aperture ratio, then the screen-to-body ratio is improved, but the reliability of signal and light path transmission deteriorates
Solution Approach 1:
The patent segments the transmission functions into separate holes: the first hole is dedicated to signal transmission with optimized dimensions for electrical conductivity, while the second hole is dedicated to light path management with optimized dimensions for optical transmission. This functional segmentation ensures reliable transmission for both signals and light while maximizing the aperture ratio.
Solution Approach 2:
The patent optimizes the local properties of each hole for its specific function: the first hole has dimensions and positioning optimized for signal transmission reliability, while the second hole has dimensions optimized for light path transmission. This localized optimization ensures both functions operate reliably simultaneously while enhancing overall aperture ratio.
