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 20240134477 titled 'TOUCH SENSOR AND METHOD TO SENSE TOUCH OF USER HAVING TOUCH ELECTRODES

Simplified Explanation

A touch sensor described in the patent application includes first touch electrodes and second touch electrodes that form mutual capacitances with the first touch electrodes. A controller generates touch data by applying a scan signal to each of the scan lines connected to the first touch electrodes and receives sensing signals from the second touch electrodes through sensing lines. The controller applies multiple pulses and a target pulse as the scan signal to each of the scan lines in different time periods. The multiple pulses include a first pulse and a second pulse of opposite phases, and pulses applied to adjacent scan lines have opposite phases.

• Touch sensor with first and second touch electrodes forming mutual capacitances
• Controller generates touch data by applying scan signals and receiving sensing signals
• Multiple pulses with opposite phases applied to scan lines in different time periods

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.
