Array Substrate Corner Wiring for Narrower Display Borders
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display panel technologies face challenges in increasing the screen occupancy ratio, particularly with abnormal-shaped displays where the non-rectangular design leads to inefficient wiring arrangements, resulting in wider borders and reduced screen real estate.
Innovation Solution
The array substrate design optimizes wiring in non-display areas by allowing only once wiring of signal lines at corners, reducing space occupation and enabling narrower borders, which enhances the screen occupancy ratio. This is achieved by strategically placing data end circuits and shift registers in non-display areas adjacent to the display area, allowing direct connections without bypassing shift registers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If signal lines are routed through corner non-display areas in conventional display panels, then the display panel can be manufactured with standard wiring patterns, but the border width increases and screen occupancy ratio decreases
Solution Approach 1:
The patent applies dimensionality change by routing signal lines through the corner non-display area instead of along the edges. This spatial reconfiguration allows the signal transmission function to be achieved while minimizing the occupied area, thereby increasing the screen occupancy ratio without compromising manufacturability.
Solution Approach 2:
The patent implements preliminary action by pre-placing the data end circuit and shift register in the corner non-display area before final signal line routing. This advance preparation enables optimized signal line paths that minimize border width and maximize display area.
2Area of stationary object
If data end circuits and shift registers are placed in corner non-display areas, then screen occupancy ratio increases, but wiring complexity increases
Solution Approach 1:
The patent merges the data end circuit and shift register into the corner non-display area, combining multiple functional components into a single optimized location. This consolidation reduces the overall wiring complexity by minimizing the number of signal line connections required while maintaining all necessary functions.
3Area of stationary object
If border area is reduced to increase screen occupancy, then screen real estate increases, but space for signal lines and circuits becomes limited
Solution Approach 1:
The patent applies local quality by concentrating all signal lines and circuits specifically in the corner non-display area rather than distributing them along the borders. This localized arrangement preserves the adaptability and versatility of signal routing while maximizing the screen real estate, as the corner area serves as a dedicated zone for electrical components.

AI summary
The present disclosure provides an array substrate and a display panel. The array substrate includes a display area and a non-display area surrounding the display area. The display area includes a first corner, and data lines extending along a first direction and gate lines extending along a second direction are provided on the display area. The first direction intersects the second direction. The non-display area includes a first non-display area, a second non-display area and a first corner non-display area. The first corner non-display area is adjacent to the first and second non-display areas. The first corner non-display area is adjacent to the first corner. A data end circuit, a first signal line section and a first shift register are located in the first corner non-display area. The data end circuit is disposed at a side of the first shift register close to the display area.
