Branched Display Connection Wires for Dead Zone Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display apparatuses have a significant dead zone due to the presence of connection wires, which affects the display area and visibility, as these wires are often visible and create distinct reflection characteristics that can be noticeable to the user.
Innovation Solution
The display apparatus incorporates connection wires with branches that diverge perpendicularly from the main wire body, covered by an insulating film with protrusions, and dummy wires arranged on the same layer, which reduces the visibility of the connection wires by creating similar reflection characteristics across the display area, thereby minimizing the dead zone.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If connection wires are used to transfer data signals from the pad area to the data lines, then data signal transmission is enabled, but the dead zone increases and visibility is affected due to visible wires with distinct reflection characteristics
Solution Approach 1:
The connection wires are divided into multiple branches that diverge from the main wire body. This segmentation allows the wires to be distributed across different locations, reducing their集中 visibility and minimizing the dead zone while maintaining signal transmission functionality.
Solution Approach 2:
An insulating film with protrusions is applied specifically at the gaps between adjacent branches rather than uniformly across the entire wire structure. This localized modification creates uniform reflection characteristics only where needed, reducing visibility without affecting the overall wire function.
2Productivity
If connection wires are arranged in parallel to transfer data signals, then signal transmission efficiency is improved, but the wires become more visible and the dead zone increases
Solution Approach 1:
The insulating film with protrusions is selectively positioned at the gaps between parallel branches, creating uniform reflection characteristics only at these specific locations. This localized approach reduces the visibility of the parallel wire arrangement without compromising signal transmission efficiency.
Solution Approach 2:
Dummy wires with the same U-shape configuration as the connection wires are arranged on the opposite side of the display area. These dummy wires create a symmetrical pattern that balances the visual appearance and reduces the noticeable dead zone while the connection wires perform their signal transmission function.
3Area of stationary object
If the display area is maximized by removing physical buttons, then the display area increases, but the dead zone becomes more noticeable due to visible connection wires
Solution Approach 1:
The insulating film with protrusions creates uniform reflection characteristics at specific locations (gaps between branches) rather than modifying the entire wire structure. This selective modification reduces the visual impact of connection wires in the maximized display area while maintaining their electrical function.
Solution Approach 2:
Dummy wires are created as copies of the connection wire pattern and placed symmetrically on the opposite side of the display area. This copying approach creates visual balance that minimizes the noticeable dead zone, allowing the display area to be maximized without sacrificing aesthetic quality.
