Shielding Patterns Mask Gaps Between Connecting Wires and Dummy Patterns
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices face challenges in minimizing the size of non-display areas while maintaining display quality, particularly in achieving uniformity and preventing the visibility of gaps between components that can affect image clarity and aesthetics.
Innovation Solution
The implementation of a display device design that includes a combination of data wires, connecting wires, dummy patterns, and shielding patterns, where the dummy patterns are disposed in the same layer as the connecting wires, creating gaps between them, and the shielding patterns overlap with these gaps to prevent light reflection and smudges, thereby minimizing the non-display area and enhancing display quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the non-display area is minimized to enhance display coverage, then the display area ratio is improved, but gaps between connecting wires and dummy patterns become visible affecting display quality
Solution Approach 1:
A shielding pattern is introduced as an intermediary element positioned between the connecting wire and dummy pattern. This shielding pattern overlaps the gap region and prevents light from entering or reflecting off the gap, thereby eliminating the visual defect while allowing the non-display area to be minimized
Solution Approach 2:
The gap between connecting wires and dummy patterns, which initially represents a harmful visual defect, is converted into a beneficial feature by positioning the shielding pattern to overlap it. The shielding pattern transforms the harmful light reflection or visibility issue into an opportunity to enhance display uniformity by blocking the gap from view
2Manufacturing precision
If shielding patterns are added to block light reflections and improve display quality, then display quality is improved, but device complexity increases
Solution Approach 1:
The shielding pattern is merged with existing display structure layers, specifically positioned to overlap the gap between connecting wires and dummy patterns. By integrating the shielding function into the existing layer structure rather than adding completely separate components, the complexity increase is minimized while achieving the light-blocking function
Solution Approach 2:
The shielding pattern serves multiple functions simultaneously: it blocks light reflections, masks the gap between components, and maintains display uniformity. This multi-functionality reduces the need for additional separate components, thereby limiting the increase in device complexity

Function Achieved in This Case
This design effectively reduces the visible non-display areas, improves image clarity by blocking external light reflections, and maintains high display quality by ensuring that the gaps do not interfere with the display functionality or aesthetics.
Implementation Method 1
shielding patterns disposed on the connecting wires. First gaps are defined between the connecting wires and the dummy patterns, and the shielding patterns overlap with the first gaps
