Display Panel Electrode Routing for Narrow-Bezel Uniformity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display panels in the related art suffer from larger bezels due to the necessity of routing first electrode power lines around the active area, which increases the bezel size.
Innovation Solution
The display panel design includes a first isolation structure with isolation openings and a connection portion in the bezel area, allowing the first electrode voltage to be transmitted through the isolation structure in the active area, reducing the need for additional connection portions in other bezel areas and minimizing bezel size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If first electrode power lines are routed around the active area in all bezel areas, then electrical connection is ensured, but bezel size increases
Solution Approach 1:
The patent applies local quality by providing connection portions only in specific bezel areas (first bezel area with bonding area) rather than uniformly in all bezel areas. The first electrode voltage is transmitted through the isolation structure in the active area to the connection portion in the first bezel area, which then extends to the bonding area. This localized approach ensures electrical connection while minimizing bezel size in other areas.
2Reliability
If connection portions are provided in all bezel areas, then electrical connection is ensured, but device complexity increases
Solution Approach 1:
The patent extracts the connection function from the traditional routing approach by utilizing the isolation structure in the active area as a voltage transmission path. Instead of providing separate connection portions in all bezel areas, the solution extracts only the necessary connection portion in the first bezel area with bonding area, simplifying the overall structure while maintaining electrical connection reliability.
