1. A touch screen device, comprising:

  • a panel body, on which a plurality of transmission electrodes extending parallel to each other and a plurality of receiving electrodes extending parallel to each other are arranged in a grid pattern, to provide a plurality of electrode intersections between the plurality of transmission electrodes and the plurality of receiving electrodes;

    a transmitter that applies a drive signal to each of the plurality of transmission electrodes;

    a receiver that receives an output signal from each of the plurality of receiving electrodes in response to the drive signal applied to each of the plurality of transmission electrodes, and outputs detection data of each of the plurality of electrode intersections; and

    a system controller that detects a touch position based on the detection data output from the receiver,the receiver comprising;

    a receiving signal processor that processes the output signal from each of the plurality of receiving electrodes, and outputs the detection data;

    two data storages that respectively store the detection data output from the receiving signal processor on a transmission electrode basis; and

    a first selector that alternately selects outputs of the two data storages such that one of the two data storages performs writing of the detection data while the other of the two storages performs reading of the detection data.
