Display Panel Terminal Layout for Narrow-Bezel UHD Screens
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High-resolution display panels require more connection terminals, leading to a wider border and reduced screen-to-body ratio, which complicates manufacturing and affects industrial design.
Innovation Solution
The connection terminals on display panels and chip-on-film are arranged in nonparallel rows, reducing space occupation and improving the borderless effect and screen-to-body ratio by orienting long edges at acute or obtuse angles, allowing for higher resolution without increasing the border width.

Engineering Contradiction Analysis
1Quantity of substance
If more connection terminals are arranged in parallel rows to achieve higher resolution, then the number of connection terminals increases, but the border width increases and screen-to-body ratio decreases
Solution Approach 1:
The patent transitions from arranging all connection terminals in parallel rows (one-dimensional arrangement) to arranging terminals in multiple rows with different orientations (two-dimensional arrangement). Specifically, the first connection terminals are arranged in a first row along a first direction, while the second connection terminals are arranged in a second row along a second direction that does not parallel the first direction. This dimensional change allows terminals to be packed more efficiently within the same border area, increasing the number of terminals without proportionally increasing the border width.
Solution Approach 2:
The patent introduces asymmetry in the arrangement of connection terminals by using two different directions for the two rows of terminals. The first row of connection terminals is oriented along a first direction, while the second row is oriented along a second direction that does not parallel the first direction. This asymmetric arrangement optimizes space utilization and reduces the overall border area compared to symmetric parallel arrangements.
2Area of stationary object
If connection terminals are arranged in nonparallel rows to reduce border area, then screen-to-body ratio improves, but manufacturing complexity may increase
Solution Approach 1:
The patent divides the connection terminals into two distinct groups: first connection terminals arranged in a first row along a first direction, and second connection terminals arranged in a second row along a second direction. This segmentation allows each group to be optimized independently for its specific function and orientation, simplifying the overall manufacturing process by breaking down the complex nonparallel arrangement into two manageable, organized rows.
