Touch Panel Antenna Integration via Decoration Layer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional touch panels expose insulation layers and sensing wires, making them aesthetically unpleasing, and integrating antennas in electronic devices leads to signal attenuation and increased volume due to external placement.
Innovation Solution
A touch panel design integrating an antenna component within the peripheral area, hidden by a decoration layer, along with sensing units and wires, allowing for a single transparent plate configuration and improved antenna placement for reduced volume and enhanced aesthetics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the antenna is placed externally or attached to mechanical components, then the antenna can be configured for wireless functionality, but the antenna is affected by mechanical components causing signal attenuation and the device volume cannot be reduced
Solution Approach 1:
The patent merges the antenna with the touch panel by integrating the antenna into the peripheral area of the touch panel structure. The antenna is positioned between the first plate and second plate, utilizing the existing structural space rather than adding external components. This combining approach eliminates the need for separate antenna mounting while improving signal transmission by removing interference from mechanical components.
2Volume of stationary object
If the antenna is integrated within the touch panel, then the device volume is reduced, but the antenna may be visually exposed affecting appearance
Solution Approach 1:
The antenna is nested within the multi-layer structure of the touch panel, specifically positioned between the first plate and second plate in the peripheral area. This nesting allows the antenna to be concealed within the existing structural layers, maintaining a clean external appearance while achieving compact integration. The touch panel structure itself serves as the housing for the antenna.
Solution Approach 2:
The antenna is strategically positioned in the peripheral area of the touch panel, which is a local region that does not interfere with the touch input area. This localized placement allows the antenna to be integrated without affecting the visual quality of the main display area, as the peripheral region is less critical for aesthetic purposes.
3Shape
If additional borders or non-transparent materials are added to hide the insulation layer and sensing wires, then the appearance is improved, but the device complexity and volume increase
Solution Approach 1:
The peripheral area of the touch panel serves multiple functions: it provides structural support, contains the antenna integration, and conceals the sensing wires and insulation layers. By making this region multi-functional, the design eliminates the need for separate aesthetic cover elements, reducing overall device complexity while maintaining appearance quality.

AI summary
A touch panel includes a first plate, an antenna component and a decoration layer. A touch input area and a peripheral area aside to the input area are defined on the first plate. The antenna component is located at the peripheral area. The decoration layer is located at the peripheral area and hides the antenna component from view.
