Display Panel Overlapping Data-Line Bypass for Lower Coupling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display panels face challenges in integrating additional functions while maintaining a large display area, requiring efficient data line management to minimize the non-display area and prevent image quality degradation due to data line coupling.
Innovation Solution
The display panel design includes a substrate with a display area, an intermediate area, and a first area, featuring data lines that bypass the edges of the first area, with overlapping bypass portions in the intermediate area, and strategically arranged pixel circuits to reduce the intermediate area's size and minimize data line coupling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data lines are routed through the first area to connect display area components, then electrical connectivity is achieved, but the non-display area increases and image quality degrades due to data line coupling
Solution Approach 1:
The data lines are routed through the intermediate area in a direction substantially perpendicular to the scan line direction, utilizing the third dimension (depth/layering) and alternative spatial dimension to bypass the first area. This dimensional routing change allows data lines to connect display area components without occupying additional non-display area and without causing coupling interference.
2Reliability
If data lines are routed through the first area, then electrical connectivity is achieved, but image quality degrades due to data line coupling
Solution Approach 1:
The data lines are extracted from the conventional routing path through the first area and relocated to the intermediate area. This extraction removes the data lines from the harmful coupling environment near the display area edges, eliminating the interference while maintaining necessary electrical connectivity through the alternative intermediate area path.
3Adaptability or versatility
If the intermediate area is enlarged to accommodate additional functions, then functional integration is improved, but the display area proportion decreases
Solution Approach 1:
Additional functional components are arranged in the intermediate area utilizing spatial dimension optimization and layering strategies. This allows multiple functions to be integrated within the existing intermediate area boundaries without requiring expansion, thereby maintaining the display area proportion while achieving functional versatility.
