Touch Sensor Line Piece Data Transmission for Noise Filtering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing touch detection systems transmit excessive information from all sensing electrodes, wasting resources and requiring extensive analysis to identify corresponding proximity events, as they must transmit and process data from the entire screen.
Innovation Solution
The method involves transmitting and detecting sensing information from specific line pieces of electrodes, rather than the entire screen, allowing for efficient transmission and processing of only relevant data, thereby reducing resource usage and improving analysis efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sensing information from all sensing electrodes is transmitted, then complete touch detection coverage is achieved, but transmission resources are wasted and excessive information is transmitted
Solution Approach 1:
The patent divides the sensing electrode array into multiple line pieces (first line piece, second line piece, third line piece, etc.) along the first direction. Instead of transmitting data from all electrodes, only selected line pieces are transmitted based on detection results, thereby segmenting the transmission workload and reducing overall data transmission volume.
Solution Approach 2:
The patent extracts and transmits only the sensing information from specific line pieces that are most likely to contain touch events, rather than transmitting information from all sensing electrodes. This extraction approach removes unnecessary data transmission while maintaining effective touch detection coverage.
2Reliability
If sensing information from all sensing electrodes is transmitted, then complete touch detection coverage is achieved, but the receiver requires extensive analysis to identify proximity events
Solution Approach 1:
The transmitting processor segments the sensing electrode data into multiple line pieces and selectively transmits only relevant line pieces to the receiving processor. This segmentation reduces the total data volume that the receiver must analyze, thereby simplifying the analysis complexity while maintaining comprehensive touch detection coverage through coordinated transmission of multiple line pieces.
Solution Approach 2:
The transmitting processor extracts and identifies specific line pieces containing touch event information before transmission. By pre-filtering and extracting only the relevant line pieces that contain proximity or touch events, the system significantly reduces the analysis burden on the receiving processor while ensuring that all necessary touch detection information is conveyed.
3Loss of information
If sensing information from all sensing electrodes is transmitted, then comprehensive data is available, but transmission time and processing time increase
Solution Approach 1:
The patent segments the sensing electrode array into multiple line pieces and transmits them in an optimized sequence (first line piece, second line piece, third line piece, etc.). This segmentation allows the system to transmit comprehensive sensing information across all necessary line pieces while reducing the total transmission time compared to transmitting all electrode data at once, as only relevant line pieces are selected and transmitted.
Solution Approach 2:
The transmitting processor extracts and identifies line pieces containing touch or proximity events before transmission. By pre-processing the data to extract only the relevant line pieces that contain meaningful touch information, the system maintains sensing information completeness for touch detection while significantly reducing both transmission time and processing time at the receiver.
