Touch screen device

Abstract

A panel main body comprises a plurality of transmitting electrodes provided in parallel to one another and a plurality of receiving electrodes provided in parallel to one another, and the transmitting electrodes and the receiving electrodes being disposed in a grid shape. A transmitter applies pulse signals to the transmitting electrodes, and a receiver receives output signals from the receiving electrodes in response to the pulse signals applied to the transmitting electrodes and outputs level signals at electrode intersections of the transmitting electrodes and the receiving electrodes. A controller detects a touch position based on the level signals output from the receiver. The controller also controls a number of pulses of a pulse signal that the transmitter applies to each transmitting electrode while the receiver receives an output signal from each receiving electrode.
