TOUCH SCREEN SYSTEM
First Claim
1. A touch screen system, comprising:
- a plurality of electronic pens;
a panel main body comprising a touch surface, on which a touch operation is performed with the electronic pens, a plurality of transmitting electrodes extending in parallel to one another, and a plurality of receiving electrodes extending in parallel to one another, the transmitting and receiving electrodes being arranged in a grid pattern, to provide a plurality of electrode intersections between the plurality of transmitting electrodes and the plurality of receiving electrodes;
a transmitter that applies a driving signal to the transmitting electrodes;
a receiver that receives a response signal output from the receiving electrodes that have responded to the driving signal applied to the transmitting electrodes, and outputs detection data of each electrode intersection; and
a controller that detects a touch position based on the detection data output from the receiver,wherein each of the plurality of electronic pens transmits a pen identification signal including pen identification information to the receiving electrodes at the time of the touch operation; and
the controller determines an electronic pen that performs the touch operation based on the pen identification signal received by the receiver through the receiving electrodes.

Abstract
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.
