TOUCH SENSOR AND METHOD TO SENSE TOUCH OF USER HAVING TOUCH ELECTRODES - A simplified explanation of the abstract
This abstract first appeared for US patent application 18331639 titled 'TOUCH SENSOR AND METHOD TO SENSE TOUCH OF USER HAVING TOUCH ELECTRODES
Simplified Explanation
The touch sensor described in the abstract is a device that can detect touch input by generating touch data through mutual capacitances between first touch electrodes and second touch electrodes. The controller applies a scan signal to the first touch electrodes and receives sensing signals from the second touch electrodes to detect touch input accurately.
- First touch electrodes and second touch electrodes form mutual capacitances.
- Controller generates touch data by applying a scan signal to first touch electrodes and receiving sensing signals from second touch electrodes.
- Controller applies multiple pulses and a target pulse as the scan signal in different time periods to improve touch detection accuracy.
- Multiple pulses applied to adjacent scan lines have opposite phases to each other.
Potential Applications
The technology can be used in various touch-sensitive devices such as smartphones, tablets, touchscreens, and interactive displays.
Problems Solved
1. Improved touch detection accuracy. 2. Enhanced sensitivity to touch input. 3. Reduction of false touch detections.

The abstract does not mention the power consumption of the touch sensor and whether it is optimized for energy efficiency.
Original Abstract Submitted
A touch sensor includes first touch electrodes, second touch electrodes that form mutual capacitances with the first touch electrodes, and a controller that generates touch data by applying a scan signal to each of scan lines connected to the first touch electrodes during substantially a same time and that receives sensing signals from the second touch electrodes through sensing lines. The controller applies a plurality of multiple pulses and a target pulse as the scan signal to each of the scan lines in a plurality of time periods. Each of the plurality of multiple pulses includes a first pulse and a second pulse of phases opposite to each other. Multiple pulses applied to scan lines adjacent to each other among the scan lines have phases opposite to each other.
