Solution Overview
Problem
When a touch sensor is applied to a display panel, display unevenness due to the touch sensor can be visually recognized.
Innovation Solution
A touch sensor design featuring a first conductor with a net-like wiring line and a second conductor adjacent to it, both with disconnection points where the disconnection edge intersects a specific direction in a plan view, reducing directivity in light reflectivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a metal mesh structure is used in the touch sensor, then the touch sensor can be manufactured with conventional processes, but display unevenness occurs due to light reflectivity directivity
Solution Approach 1:
The continuous metal mesh wiring lines are segmented by introducing discontinuities that divide the mesh into multiple sections. This segmentation disrupts the directivity of light reflection while maintaining the electrical conductivity and touch sensing functionality, thereby reducing display unevenness without compromising manufacturability
Solution Approach 2:
The discontinuities are strategically positioned at specific locations within the metal mesh structure, creating local variations in the mesh pattern. This local modification approach allows the touch sensor to maintain uniform electrical properties while selectively addressing the light reflection directivity issue in specific areas, thus reducing display unevenness
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design reduces display unevenness by equalizing light reflectivity in different directions, thereby improving the display quality of the display panel.
Implementation Method 1
the net-like wiring line of the first conductor includes a plurality of disconnection points in which a disconnection edge intersects the first direction in a plan view

AI summary
A touch sensor includes: a first conductor including a net-like wiring line; and a second conductor adjacent to the first conductor and including a net-like wiring line. At least a part of a boundary portion between the first conductor and the second conductor extends in a first direction, and the net-like wiring line of the first conductor includes a plurality of disconnection points formed such that a disconnection edge intersects the first direction in a plan view.
