摘要： 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.

摘要： Touch positions can be detected with a high accuracy. A receiver receives a charge-discharge current signal of a receiving electrode in response to a drive (pulse) signal applied to a transmission electrode, and outputs a level signal of each electrode intersection. The receiver includes an IV converter that converts the charge-discharge current signal to a voltage signal. A conversion characteristic of the IV converter is set such that phases of amplitude of the voltage signal corresponding to a leading edge and a trailing edge of a pulse wave of the drive signal substantially match each other, and phases of amplitude of the voltage signal corresponding to the trailing edge of the pulse wave and a leading edge of a succeeding pulse wave substantially match each other.

摘要： In a touch panel device comprising a panel main body (4) including a grid array of transmission electrodes (2) and reception electrodes (3) and defining a touch surface (51), the transmission electrodes are connected to a transmission unit (5) for sequentially applying a drive signal to the transmission electrodes. A time constant element is connected to each transmission electrode via the corresponding lead wire to adjust an overall time constant of the transmission electrode, the time constant of each time constant element being selected to be greater as the length of the lead wire for the corresponding transmission electrode increases. Thereby, the induction noises induced in the reception electrodes owing to the drive signal conducted through the lead wires leading to the transmission electrodes can be minimized and homogenized among the different transmission electrodes, and the positional variations in the distribution of the sensitivity of touch position detection owing to the variations in the lengths of the lead wires leading to the transmission electrodes can be minimized.

摘要： A reception signal processor of a touch screen device receives a response signal output from receiving electrodes that have responded to a driving signal applied to transmitting electrodes and outputting detection data of each electrode intersection. The reception signal processor includes an integrator and a monitor. The integrator integrates a signal obtained by performing a predetermined process on an output signal from the receiving electrodes, and the monitor outputs a reset signal when an integrated value of the integrator reaches a predetermined threshold value. The integrator resets the integrated value to zero in response to the reset signal from the monitor. In particular, a smoother that smoothes a signal is provided before the integrator, and the integrator integrates the signal that has been smoothed by the smoother.
