TOUCH CONTROLLER, TOUCH SENSING DEVICE, AND TOUCH SENSING METHOD |
| 摘要 |
A touch controller includes a driving signal transmitter and a sensing signal receiver. The driving signal transmitter is configured to generate a driving signal by spreading a frequency of an input signal to a first frequency and a second frequency. The first frequency is higher than a preset carrier frequency and the second frequency is less than the carrier frequency. The driving signal transmitter inputs the driving signal to a touch panel. The sensing signal receiver is configured to receive a sensing signal generated in the touch panel based on the driving signal and generate touch data based on the sensing signal. |
