Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing demand for high touch precision in electronic devices leads to a need for high-performance control chips, resulting in higher costs and larger volumes, making existing touch devices costly and bulky.
Innovation Solution
A method where the touch sensor generates a touch sensing signal and transfers it to the operating system, which converts it to a touch signal and returns it to the device for coding, reducing the performance requirements of the control chip, allowing for the use of lower-performance chips and thus lowering costs and volumes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a high-performance control chip is adopted to enhance signal processing ability, then touch precision is improved, but cost and volume of the touch device increase
Solution Approach 1:
The patent segments the signal processing function into two parts: the control chip performs only basic signal acquisition and transmission, while the operating system performs the complex signal conversion and processing. This division allows the control chip to be simplified and reduced in size while maintaining overall system performance.
Solution Approach 2:
The patent introduces the operating system as an intermediary component that handles the complex signal processing tasks. The control chip transmits raw sensing signals to the operating system, which then converts them into usable touch signals, thereby relieving the control chip of heavy processing burdens.

AI summary
The present invention provides a method, a system, and an apparatus for processing a touch sensing signal, and an electronic device. The method is applied to an operating system and includes: receiving a touch sensing signal generated by a touch sensor of a touch device; converting the touch sensing signal to a touch signal, where the touch signal at least comprises a touch position signal; sending the touch signal to the touch device; receiving the touch signal coded by the touch device and transferring to a touch driver. In implementing the embodiments of the present invention, the touch sensing signal generated by the touch sensor is converted to the touch signal by the operating system followed and returned back to the touch device, and therefore the touch device do not need to perform conversion processing, which can reduce the performance requirement on its chip and lower the cost and volume of the touch device.
