Array Substrate Compensation Layout for Uniform Wiring Near Hole Areas
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional electronic devices with notches or holes in the display screen for components like front cameras reduce the screen-to-body ratio due to the need for extensive wiring, leading to issues such as uneven display and reduced space efficiency.
Innovation Solution
An array substrate design with first and second category signal lines, first connection signal lines, and first compensation signal lines that extend in different directions, along with second signal lines, to maintain consistent wiring density and reduce the need for additional connection lines at the edge of the hole area, thereby increasing the screen-to-body ratio and improving display uniformity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If signal lines are arranged in one-to-one correspondence around the notch or hole area, then connection reliability is improved, but wiring space increases reducing screen-to-body ratio
Solution Approach 1:
The patent introduces a third dimension (film layers) to arrange signal lines. Connection signal lines are positioned in different film layers from pixel circuits, allowing vertical stacking of wiring. This multi-layer approach enables signal transmission without occupying additional planar space around the hole area, thus maintaining connection reliability while preserving screen-to-body ratio.
Solution Approach 2:
The patent segments the wiring path into multiple sections across different film layers. Instead of a single continuous wiring path in one layer, the signal transmission is divided into segments that can be connected through vertical transitions between layers, reducing the horizontal space required for wiring around the hole.
2Reliability
If wiring density is increased around the hole area to maintain signal connections, then connection stability is improved, but display uniformity deteriorates due to mura effects
Solution Approach 1:
By moving connection signal lines to different film layers, the patent eliminates the need to increase wiring density in the planar display area. The additional wiring capacity is achieved vertically rather than horizontally, preventing local density variations that cause mura effects while maintaining stable signal connections.
3Adaptability or versatility
If additional connection signal lines are added around the hole area edge, then signal transmission capability is improved, but device complexity increases
Solution Approach 1:
The patent designs connection signal lines that serve multiple functions: they transmit signals between pixel circuits and external components, and their arrangement in different film layers automatically provides routing flexibility. This multi-functional design eliminates the need for additional dedicated connection lines, reducing overall wiring complexity while maintaining signal transmission capability.
