Array Substrate Signal Line Concentration for Screen-to-Body Ratio
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display technologies face challenges in maximizing the screen-to-body ratio of display panels and devices, as structural limitations hinder the full coverage of the display area with the screen.
Innovation Solution
The design of an array substrate with a display area surrounded by non-display areas, where signal lines are configured to form concentrated regions in the non-display areas, allowing for efficient wiring and reducing the space occupied by these regions, thereby increasing the screen-to-body ratio.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If signal lines are extended to the non-display area for wiring around the assembly setting area, then the wiring can be completed, but the non-display area increases, reducing the screen-to-body ratio
Solution Approach 1:
The patent applies dimensionality change by routing signal lines from the single-plane display area into the non-display area, utilizing the third dimension (depth/layering) to wrap lines around the assembly setting area. This allows wiring to be completed while minimizing the footprint of the non-display area, as lines can pass through rather than occupy extensive lateral space.
Solution Approach 2:
The patent segments the signal line routing into distinct regions: display area, non-display area, and assembly setting area. By dividing the wiring path into these segments and routing lines through the non-display area rather than expanding it, the patent reduces the overall non-display area while still achieving complete wiring connectivity.
2Area of stationary object
If the non-display area is reduced to increase screen-to-body ratio, then the display area coverage increases, but the wiring space for signal lines becomes insufficient
Solution Approach 1:
The patent implements nesting by routing signal lines through the non-display area and wrapping them around the assembly setting area. The lines are nested within the boundary defined by the display area, utilizing the non-display area efficiently for wiring without expanding the overall device footprint. This allows adequate wiring space while maintaining high display area coverage.
3Ease of manufacture
If signal lines are concentrated in the non-display area, then the wiring is organized efficiently, but the non-display area structure becomes more complex
Solution Approach 1:
The patent extracts the wiring function from the display area and concentrates it in the non-display area. By taking out all signal line routing from the display area and consolidating it in the non-display area around the assembly setting area, the patent achieves efficient wiring organization. The complexity is localized to a specific region rather than being distributed throughout the entire device structure.
