Non-quadrangular Display Data Line Routing for Load Balancing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Circular display devices experience load differences due to variations in the number of pixels connected to data lines at the center and outer sides of the panel, leading to deviations in data charge and image consistency.
Innovation Solution
Connecting data lines at the outer and center portions of a circular display panel to form a single data line, ensuring each data line carries a consistent load by extending through non-display areas and connecting pixel columns across the panel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If data lines are arranged in a conventional circular display panel, then the display device can be formed in a circular shape, but a load difference is generated due to a difference in the number of pixels connected to data lines at the center and outer sides
Solution Approach 1:
The data lines are segmented into different types: first data lines extending from the center along the reference line, and second data lines extending from the center along lines spaced apart from the reference line. This segmentation allows different data line configurations to be applied to different regions, balancing the pixel connection loads across the circular display panel.
Solution Approach 2:
The patent introduces asymmetric data line routing where second data lines are spaced at specific angles (e.g., 45 degrees or 60 degrees) from the reference line, creating an asymmetric pattern that distributes pixel connections more evenly across the circular panel, preventing load concentration at the center.
2Ease of operation
If data lines extend along the center of the circular display panel, then pixels at the center can be connected, but a deviation or variation is generated due to a difference in data charge between these data lines
Solution Approach 1:
Different data line configurations are applied to different local regions: first data lines along the reference line and second data lines along spaced lines. This local differentiation ensures that each region's data lines connect to an appropriate number of pixels, maintaining consistent data charge characteristics across the entire circular display panel.
