Display Panel Data and Power Link Layout for Bezel Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge of reducing the bezel area in display panels is hindered by the presence of link lines for data signals in the non-display area, which complicates the minimization of the non-active area.
Innovation Solution
A display apparatus with a data link structure that includes vertical and horizontal data link lines in the display area, along with a power line structure that improves common driving voltage transmission and reduces the bezel area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If link lines for data signals are disposed in the non-display area, then data signal transmission is enabled, but the bezel area cannot be reduced
Solution Approach 1:
The patent introduces horizontal data link lines extending in the second direction (horizontal) in addition to vertical data link lines extending in the first direction (vertical). This two-dimensional data link structure allows data signals to reach data lines in the display area without requiring extensive non-display area, thereby reducing bezel area while maintaining functionality
Solution Approach 2:
The data link structure is segmented into vertical data link lines and horizontal data link lines that operate in different directions. This segmentation allows the data signal transmission path to be distributed across different spatial dimensions, reducing the concentration of required space in the non-display area and enabling bezel reduction
2Reliability
If power lines are extended into the display area, then common driving voltage transmission performance is improved, but device complexity increases
Solution Approach 1:
The patent extends power distribution lines from the non-display area into the display area along the second direction (horizontal), creating a two-dimensional power distribution network. This allows common driving voltage to be delivered more effectively to data lines throughout the display area while distributing the power line structure across multiple spatial dimensions
Solution Approach 2:
The power distribution lines serve multiple functions: they transmit common driving voltage to data lines, work in conjunction with the two-dimensional data link structure, and are integrated with both vertical and horizontal link lines. This multi-functionality improves voltage transmission performance without proportionally increasing complexity
