==TOUCH CONTROLLER, OPERATING METHOD OF THE SAME, AND TOUCH SENSING DEVICE INCLUDING TOUCH CONTROLLER - A simplified explanation of the abstract==


This abstract first appeared for US patent application 17978705 titled 'TOUCH CONTROLLER, OPERATING METHOD OF THE SAME, AND TOUCH SENSING DEVICE INCLUDING TOUCH CONTROLLER

==Simplified Explanation==

The abstract describes a touch controller that includes a noise detection circuit, a driving signal generation circuit, and a receiving circuit. 

* The touch controller has a noise detection circuit that detects display noise on sensing electrodes.
* The noise detection circuit provides different reference voltages to different electrodes.
* A driving signal generation circuit generates driving signals based on the reference voltages and selects them alternately.
* A receiving circuit receives the driving signals and generates a sensing voltage based on touch sensing signals.

==Potential Applications==
This technology can be applied in various touch-sensitive devices, such as smartphones, tablets, touchscreens, and touch panels used in automotive displays, medical devices, and industrial equipment.

==Problems Solved==
1. Display noise detection: The touch controller addresses the issue of display noise interfering with touch sensing by providing separate reference voltages to different electrodes.
2. Touch sensing accuracy: By generating driving signals based on the reference voltages and selecting them alternately, the touch controller improves the accuracy of touch sensing signals.

==Benefits==
1. Improved touch sensitivity: The touch controller's noise detection circuit and driving signal generation circuit enhance the sensitivity and accuracy of touch sensing.
2. Reduced interference: By detecting and mitigating display noise, the touch controller minimizes interference and improves the overall performance of touch-sensitive devices.


==Original Abstract Submitted==

A touch controller includes a noise detection circuit that respectively provides a first reference voltage and a second reference voltage for detecting display noise to a first electrode and a second electrode arranged on lines except a line on which touch sensing is performed, among sensing electrodes, the second reference voltage being different from the first reference voltage, a driving signal generation circuit that receive a first noise voltage and a second noise voltage generated based on the first reference voltage and the second reference voltage and alternately selects the first noise voltage and the second noise voltage as a driving signal, and a receiving circuit that receives the driving signal, a touch sensing signal generated based on the driving signal from a third electrode arranged on the line on which touch sensing is performed, among the sensing electrodes, and generates a sensing voltage based on the touch sensing signal.
