Display Panel Data-Link Routing for Narrower Bezels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices face challenges in minimizing the bezel width while maintaining high image quality, particularly in organic light-emitting display devices where the width of the bezel area increases due to varying lengths of data link lines.
Innovation Solution
The display device and panel implement a structure where data lines in a first area are connected to a first data link line group with a linear structure and data lines in a second area outside the first area are connected to a second data link line group with a bending structure, ensuring all data link lines have the same length.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If data link lines are extended to connect data lines in the second area, then the display area can be expanded, but the bezel width increases due to varying lengths of data link lines
Solution Approach 1:
The patent applies local quality by making different parts of the data link line structure have different characteristics. Specifically, data link lines in the first area have different lengths while data link lines in the second area all have the same length. This localized uniformity in the second area prevents variation-induced bezel width increase, allowing display area expansion without proportional bezel widening.
Solution Approach 2:
The patent segments the data link lines into two distinct groups: first data link lines connecting to data lines in the first area, and second data link lines connecting to data lines in the second area. This segmentation allows independent optimization of each group's characteristics, enabling the second area's data link lines to maintain uniform length while the first area's data link lines can vary in length, thus resolving the bezel width issue.
2Length of stationary object
If the bezel width is minimized, then the overall device size and weight are reduced, but data link line length variation causes image quality degradation
Solution Approach 1:
The patent applies local quality by making different parts of the data link line structure have different characteristics. Specifically, data link lines in the first area have different lengths while data link lines in the second area all have the same length. This localized uniformity in the second area prevents variation-induced bezel width increase, allowing display area expansion without proportional bezel widening.

This segmentation allows independent optimization of each group's characteristics, enabling the second area's data link lines to maintain uniform length while the first area's data link lines can vary in length, thus resolving the bezel width issue.
3Adaptability or versatility
If data link lines of different lengths are used to accommodate various data line positions, then connectivity is improved, but image quality uniformity deteriorates
Solution Approach 1:
The patent segments the data link lines into two distinct groups: first data link lines connecting to data lines in the first area, and second data link lines connecting to data lines in the second area. This segmentation allows independent optimization of each group's characteristics, enabling the second area's data link lines to maintain uniform length while the first area's data link lines can vary in length, thus resolving the bezel width issue.
Solution Approach 2:
The patent applies equipotentiality by ensuring all second data link lines have the same length, creating electrical equivalence among these connection paths. This uniform length ensures that signals traveling through different second data link lines experience equal transmission characteristics, preventing image quality variations and maintaining uniformity across the display.
