摘要： Provided is a touch screen system that includes a transmitter, a plurality of electronic pens, and a controller. The transmitter applies to transmitting electrodes a pen-synchronization pulse signal for synchronizing transmission and reception of a pen identification signal between the electronic pens and a receiver. The electronic pens transmit, to receiving electrodes, a pen identification signal in accordance with detection of the pen-synchronization pulse signal of the transmitting electrodes at the time of a touch operation. The controller determines the electronic pen that has performed a touch operation based on the pen identification signal that is received by the receiver via the receiving electrodes.

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： A capacitive touch panel of the present invention is characterized by including a plurality of detection period setting section 18 to 20 and electrode range setting section 21. Detection is performed by setting a detection period for electrodes 3 and 4, which are situated in a range previously determined with reference to the electrodes 3 and 4 where a touch input is detected, so as to become larger than a detection period achieved before detection of the touch input.

摘要： A touch screen device is provided that includes a receiving signal processor, an odd number line FIFO, an even number line FIFO, and a first selector. The receiving signal processor processes output signals from receiving electrodes and outputs detection data. The odd number line FIFO and the even number line FIFO respectively store the detection data output from the receiving signal processor on a line basis. The first selector alternately selects outputs of the odd number line FIFO and the even number line FIFO. While one of the odd number line FIFO and the even number line FIFO performs writing of the detection data, the other performs reading.
