Touchscreen FM Antenna Integration via Separation Layer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile terminals with FM antennas require earphones for FM broadcast reception, limiting flexibility due to the need for unfolding or stretching, which compromises user experience.
Innovation Solution
A touchscreen terminal design incorporating a frequency modulation FM antenna layer between conductive and touch layers, separated by a separation layer, allowing for direct FM broadcast reception without earphones.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an FM antenna is implemented using earphones, then FM broadcast reception is enabled, but flexibility is reduced due to the need to carry and unfold earphones
Solution Approach 1:
The patent merges the FM antenna function with the existing touchscreen structure by integrating the antenna layer into the touchscreen's multi-layer construction. The antenna layer is incorporated between the basal layer and conductive layers, combining the display function and FM reception function into a single integrated component, eliminating the need for separate earphone-based antenna systems
Solution Approach 2:
The touchscreen structure is designed to serve multiple functions simultaneously: the basal layer provides both structural support and houses the FM antenna, while the conductive layers serve both touch sensing and antenna functions. This multi-functionality allows the terminal to receive FM broadcasts directly without requiring dedicated earphone accessories
2Adaptability or versatility
If the FM antenna is integrated into the touchscreen structure, then flexibility and convenience are improved, but interference between the antenna and conductive layers must be managed
Solution Approach 1:
The patent introduces a separation layer as an intermediary between the antenna layer and the conductive layers. This separation layer acts as a mediator that prevents harmful electromagnetic interference between the FM antenna and the touch sensor conductive layers, while still allowing the antenna to function effectively within the integrated touchscreen structure
Solution Approach 2:
The touchscreen is segmented into distinct functional layers including the antenna layer, separation layer, and conductive layers. This segmentation allows each layer to perform its specific function independently - the antenna layer for FM reception, the separation layer for interference isolation, and the conductive layers for touch sensing - thereby resolving the interference issue while maintaining integration
