Array Substrate With Segmented Gate Lines For Borderless Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current flexible display devices with edge bending techniques cannot achieve a completely borderless design due to the need for large bezel areas around openings for components like cameras and earpieces, as the edge bending technique cannot effectively handle these openings.
Innovation Solution
An array substrate design with a display area and peripheral area, featuring interconnected data lines and disconnected gate lines, allowing for an opening to accommodate functional components, and a driving method that provides scan signals and data signals row-by-row to different areas of the substrate to enable borderless display.

1Area of moving object
If edge bending technique is used to achieve narrow bezel, then the display area can be expanded, but openings for functional components cannot be effectively handled requiring large bezel area
Solution Approach 1:
The gate lines are segmented into multiple independent groups (first gate lines, second gate lines, third gate lines) that can be independently controlled. This segmentation allows different regions of the display to be activated independently, enabling the display area to extend around functional component openings while maintaining narrow bezel design.
Solution Approach 2:
The patent implements dynamic control of gate lines where different gate line groups are activated at different times or in different sequences. This dynamic activation pattern allows the display to adaptively handle openings for functional components while maintaining the appearance of a continuous narrow bezel border.
2Adaptability or versatility
If gate lines are disconnected in different display areas, then independence and flexibility are improved, but wiring complexity and manufacturing difficulty increase
Solution Approach 1:
The gate lines are divided into distinct segments (first, second, and third gate lines) with clear segmentation points. Each segment can be independently connected to drive circuits, providing the necessary independence for different display areas while maintaining manageable wiring through systematic segmentation rather than arbitrary disconnections.
Solution Approach 2:
Different regions of the display have different gate line configurations tailored to their specific needs. The first, second, and third gate lines serve different functional zones, allowing each area to have optimized wiring and control characteristics while reducing overall complexity through localized optimization.

AI summary
An array substrate, a driving method thereof, and a display device are provided. The array substrate comprises a display area and a peripheral area. The display area includes a plurality of gate lines extending in a first direction and a plurality of data lines extending in a second direction. The peripheral area includes a source driver on a side of the peripheral area along the second direction. The display area includes an opening, a first display area on a side of the opening away from the source driver, and a second display area adjacent to the first display area along the first direction. Data lines in the first display area are connected in one-to-one correspondence with data lines in the second display area, and gate lines in the first display area and gate lines in the second display area are disconnected from each other.
