Display Device Dummy Line Pattern Reduces Dead Space
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices face challenges in reducing dead space and preventing pattern visibility in the peripheral areas, which affects the overall appearance and efficiency of the display.
Innovation Solution
The implementation of a display device design that includes a substrate with a display area and a peripheral area, featuring a data line, connection line, voltage line, and dummy line with alternating horizontal and vertical patterns, which are connected in a specific layered structure to minimize dead space and reduce visibility differences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If connection lines and dummy lines are arranged in the display area, then electrical signals can be transmitted and voltage can be supplied, but dead space increases and pattern visibility occurs
Solution Approach 1:
The patent moves connection lines and dummy lines from the display area to the peripheral area, utilizing the peripheral area as an additional dimension for routing. This resolves the contradiction by separating signal transmission functions from the display area, eliminating dead space and pattern visibility while maintaining electrical signal transmission capability through strategically positioned connection lines that extend from peripheral to display areas.
2Productivity
If connection lines are extended to cover the entire display area, then signal transmission is improved, but dead space and pattern visibility increase
Solution Approach 1:
The patent applies local quality by positioning connection lines and dummy lines specifically in the peripheral area rather than uniformly across the entire display area. This localized arrangement maintains signal transmission functionality where needed while minimizing dead space and pattern visibility in the display area, achieving optimal balance between coverage and aesthetic quality.
3Stability of the object's composition
If dummy lines are added to match connection line patterns, then visibility differences are reduced, but device complexity increases
Solution Approach 1:
The patent uses dummy lines that replicate the pattern and layout of connection lines in the peripheral area. This copying approach creates visual uniformity across the display surface, reducing visibility differences and improving aesthetic quality while maintaining a systematic and manageable line pattern structure that does not excessively increase device complexity.
