Asymmetric Display Data-Line Routing to Reduce Signal Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display apparatuses experience a reduction in image quality due to signal interference between adjacent lines, which affects the performance and clarity of the displayed images.
Innovation Solution
The display apparatus is designed with a specific arrangement of pixel groups and data lines, including a first pixel group with red-based and blue-based pixels, a second pixel group with green-based pixels, and a data distributor that alternately transfers data signals to data lines, with varying lengths and orientations of horizontal lines to minimize signal interference.

Engineering Contradiction Analysis
1Productivity
If data lines are arranged adjacent to each other to transfer data signals to pixel groups, then data signal transfer efficiency is improved, but signal interference between adjacent lines increases causing image quality degradation
Solution Approach 1:
The patent applies asymmetry by making the first horizontal line (adjacent to blue-based pixels) longer than the second and third horizontal lines (adjacent to green-based pixels). This asymmetric length configuration creates unequal signal path lengths that reduce constructive interference between adjacent data lines, thereby mitigating signal interference while maintaining efficient data transfer to all pixel groups
Solution Approach 2:
The patent applies local quality by differentiating the characteristics of data lines based on their adjacent pixel groups. Specifically, the first horizontal line has a different length than the second and third horizontal lines, creating localized variations in signal transmission properties. This allows each data line to be optimized for its specific position and reduces interference effects that would uniformly affect all lines
2Object-affected harmful factors
If the first horizontal line is made longer than the second and third horizontal lines to reduce signal interference, then image quality is improved, but device complexity increases
Solution Approach 1:
The patent applies parameter changes by modifying the length parameter of the first horizontal line relative to the second and third horizontal lines. This single parameter change (length differentiation) provides a simple yet effective means to reduce signal interference between adjacent data lines without requiring complex routing or additional components, thus achieving interference reduction with minimal increase in device complexity
