Touch Sensor Integrated with Light Emitting Unit for Mobile Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional touch screen mobile phones require an additional FPC for the touch sensor unit, leading to increased costs and adhesion processes.
Innovation Solution
Integrating the touch sensor unit onto the light emitting unit, which is electrically connected to the control circuit, eliminating the need for an additional FPC to be adhered to the cover plate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the touch sensor unit is disposed on a separate FPC and adhered to the cover plate, then the touch sensing function can be achieved, but the manufacturing cost increases and the adhesion process is complicated
Solution Approach 1:
The patent merges the touch sensor unit with the light emitting unit by disposing the touch sensor unit directly on the light emitting unit. This integration eliminates the need for a separate FPC and adhesion process, thereby reducing manufacturing cost and process complexity while maintaining the touch sensing function.
2Ease of manufacture
If the touch sensor unit is disposed on the light emitting unit, then the manufacturing cost is reduced and adhesion process is eliminated, but the electrical connection to control circuit needs to be ensured
Solution Approach 1:
The patent combines the touch sensor unit and light emitting unit into a single integrated structure, where the touch sensor unit is disposed on the light emitting unit. The light emitting unit's FPC provides electrical connection to the control circuit, ensuring reliability while simplifying manufacturing.
