Pixel Array Bridge Point Distribution for Slim Border Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing pixel array designs for slim border displays suffer from non-continuous distribution of bridge points, leading to differences in charging time for neighboring pixels, resulting in band mura and compromised display quality due to the limitations of wire design.
Innovation Solution
A pixel array design where the second signal lines intersect with a connection line between bridge points of neighboring first signal lines, ensuring only one intersection per pair of first signal lines, reducing the distance between bridge points and enhancing the continuity of signal distribution, thereby reducing charging time differences and improving display quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If selection lines are configured besides scan lines and data lines with bridge points to transmit scan signals, then the width of the non-display region is narrowed, but the distribution of bridge points becomes non-continuous resulting in band mura
Solution Approach 1:
The pixel array is divided into multiple pixel rows and pixel columns, with bridge points strategically distributed at intersections of selection lines and first signal lines. This segmentation allows continuous RC distribution across multiple discrete bridge points, solving the band mura issue while maintaining slim border design.
Solution Approach 2:
Selection lines are introduced as an additional dimensional element intersecting with first signal lines to create bridge points. This adds a new routing dimension that enables continuous RC distribution without increasing the non-display region width, resolving the contradiction between slim border and display quality.
2Device complexity
If bridge points are distributed non-continuously due to wire design limitations, then the structure is simpler, but charging time for neighboring pixels differs resulting in band mura
Solution Approach 1:
The invention ensures continuous RC distribution by strategically placing bridge points at intersections of selection lines and first signal lines across adjacent pixel rows. This continuity equalizes charging times for neighboring pixels, eliminating band mura while maintaining manageable wire design complexity.
3Ease of manufacture
If the distance between bridge points is large, then the wire routing is simpler, but charging time differences between neighboring pixels increase causing band mura
Solution Approach 1:
The invention dynamically adjusts the distribution density of bridge points based on pixel row positioning. Adjacent pixel rows share selection lines with multiple bridge points, creating a dynamic routing pattern that reduces distances between bridge points for critical neighboring pixels while maintaining overall routing simplicity.

AI summary
A pixel array including first signal lines, second signal lines, active elements, pixel electrodes and selection lines is provided. The second signal lines and the selection lines are intersected with the first signal lines respectively. Each first signal line has a bridge point at an intersection with the one of the selection lines. At least one of the selection lines is disposed between two neighboring second signal lines. Amounts of the first signal lines and the selection lines are larger than an amount of the second signal lines respectively, and an amount of second signal lines intersected with a connection line between the bridge point of the ith first signal line and the bridge point of the (i+1)th first signal line is one, i=1 to N, and N is the amount of the first signal lines.
