==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

== Potential Applications ==
The technology can be used in various touch-sensitive devices such as smartphones, tablets, laptops, and touchscreens in cars.

== Problems Solved ==
The touch sensor helps in accurately detecting touch inputs and gestures, improving the user experience and responsiveness of touch-enabled devices.

== Benefits ==
- Enhanced touch sensitivity and accuracy
- Improved user interaction with touchscreens
- Faster response time to touch inputs

== Potential Commercial Applications ==
"Touch Sensor Technology for Enhanced User Experience in Smart Devices"

== Possible Prior Art ==
Prior touch sensor technologies may have used similar principles of applying scan signals and receiving sensing signals to detect touch inputs, but the specific method of applying multiple pulses with opposite phases to adjacent scan lines may be a novel aspect of this technology.

==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.
