Metal Mesh Breakpoint Compensation for Lower Display Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The visibility of metal meshes in electronic devices is enhanced by breakpoints, which decreases the viewing quality due to differences in opening rates, making it difficult to reduce their visibility effectively.
Innovation Solution
Incorporating a compensating line segment adjacent to breakpoints in the metal mesh, which is electrically insulated and does not completely overlap the breakpoints, to reduce the visual impact of these discontinuities while being part of the same conductive layer, thereby minimizing costs.

Engineering Contradiction Analysis
1Reliability
If breakpoints are introduced to separate electrodes in the metal mesh, then the sensing function is enabled, but the visibility of the metal mesh is enhanced and viewing quality decreases
Solution Approach 1:
A compensating line segment is introduced as an intermediary element between the metal line segments at the breakpoint. This compensating line segment is electrically insulated from the metal lines but positioned adjacent to the breakpoint, serving as a visual compensator that masks the discontinuity caused by the breakpoint while allowing the sensing function to operate through the electrically conductive metal lines.
Solution Approach 2:
The compensating line segment is designed with visual properties (such as color, transparency, or pattern matching) that allow it to blend with the surrounding metal mesh structure. By matching the visual characteristics of the metal lines, the compensating line segment effectively camouflages the breakpoint, reducing the enhanced visibility caused by the discontinuity.
2Object-affected harmful factors
If compensating line segment is added to reduce breakpoint visibility, then viewing quality is improved, but device complexity increases
Solution Approach 1:
The compensating line segment is integrated into the same conductive layer as the metal lines, rather than being placed in a separate layer. This merging approach allows the compensating element to be manufactured together with the metal mesh structure in a single fabrication process, reducing overall device complexity despite the added visual compensation function.
Solution Approach 2:
The compensating line segment, while primarily serving as a visual compensator, is designed to coexist within the same conductive layer structure as the functional metal lines. This multi-functional design allows a single layer to serve both sensing purposes (through metal lines) and visual compensation purposes (through compensating line segments), thereby reducing the need for additional separate structures.

AI summary
An electronic device includes a first conductive layer including a first metal mesh including a first metal line segment, a second metal line segment and a first compensating line segment. The first metal line segment extends along a first direction and has a first end, and the second metal line segment extends along the first direction and has a second end, wherein a first breakpoint exists between the first end and the second end. The first compensating line segment is separated from and electrically insulated from the first metal line segment and the second metal line segment, the first compensating line segment does not completely overlap the first breakpoint, and a minimum distance between the first breakpoint and each first segment end of the first compensating line segment is less than or equal to 50 μm.
