CPC G06F 3/04182 (2019.05) [G06F 3/0446 (2019.05); G06F 3/0447 (2019.05)] | 25 Claims |
1. An input sensing device, comprising:
first driving electrodes, second driving electrodes, and sensing electrodes; and
a sensing driver that transmits a first driving signal to the first driving electrodes at a first frequency, transmits a second driving signal to the second driving electrodes at a second frequency, and determines a touch or approach of an external object based on sensing signals received from the sensing electrodes,
wherein the sensing driver comprises analog front-end circuits that separate a sensing signal of the first frequency from a sensing signal of the second frequency that are received from the respective sensing electrodes, and generates digital sensing data based on a result of recombining the separated sensing signals.
