Curved Edge Shift Register Orientation for Narrow Bezel Array Substrates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Special-shaped display panels with curved edges face challenges in minimizing the bezel width due to conventional shift register unit arrangements, which occupy a larger area and complicate manufacturing.
Innovation Solution
The array substrate design features shift register units in the peripheral area with edges parallel or consistent with the curved edge of the display area, allowing for a narrower bezel by optimizing the arrangement based on the curvature, reducing the peripheral area and simplifying manufacturing.

1Area of stationary object
If shift register units are arranged in a conventional manner in the peripheral area, then the arrangement is simple and easy to manufacture, but the area occupied by shift register units is increased, resulting in a wider bezel
Solution Approach 1:
The patent applies local quality by making the arrangement of shift register units adapt to different regions of the peripheral area. Specifically, the extending direction of the first edge of each shift register unit is adjusted based on its position: at positions corresponding to the curved edge, the extending direction is parallel to the outer tangent line of the curved edge, while in other positions, conventional arrangement is used. This localized adaptation reduces the area occupied by shift register units in the curved region without complicating the overall manufacturing process.
Solution Approach 2:
The patent applies curvature by aligning the first edge of shift register units with the curved edge of the display area. The extending direction of the first edge is made parallel to the outer tangent line of the curved edge at corresponding positions, creating a curved arrangement that follows the contour of the display area. This curved arrangement optimizes space utilization and reduces the bezel width while maintaining manufacturing feasibility.
2Length of stationary object
If shift register units are arranged to reduce the occupied area for narrow bezel, then the bezel width is reduced, but the arrangement becomes more complex
Solution Approach 1:
The patent implements local quality by applying the curved arrangement only at positions corresponding to the curved edge of the display area, while maintaining conventional arrangement in other positions. This localized approach reduces the bezel width in the critical curved region without making the entire arrangement complex, thus achieving narrow bezel with controlled complexity.
Solution Approach 2:
The patent applies segmentation by dividing the peripheral area into different regions: positions corresponding to the curved edge and other positions. Different arrangement strategies are applied to different segments - curved arrangement for the curved edge region and conventional arrangement for other regions. This segmentation allows the system to achieve narrow bezel where needed while maintaining overall simplicity.
