Abstract
A touch panel device includes a touch panel including sensing electrodes, a selector circuitry; a sensing circuitry configured to generate sensed signals having signal levels depending on self-capacitances of connected ones of the sensing electrodes, and a processor configured to perform touch sensing of the touch panel, based on the sensed signals. When the touch panel device is placed in a first state, the selector circuitry electrically connects first sensing electrodes to the sensing circuitry in each operation cycle. When the touch panel device is placed in a second state, the selector circuitry electrically connects second sensing electrodes to the sensing circuitry in each operation cycle. The number of the second sensing electrodes connected to the sensing circuitry in each operation cycle for the second state is less than the number of the first sensing electrodes connected to the sensing circuitry in each operation cycle for the first state.
