<p><P>PROBLEM TO BE SOLVED: To eliminate the duplication of components to reduce component costs in the signal processing circuit of an electrostatic capacity type touch panel. <P>SOLUTION: A touch panel 51 is formed on a glass substrate 200. Sensor circuits 50A and 50B are arranged along a Y direction in the periphery of the touch panel 51, and sensor circuits 50C and 50D are arranged along an X direction. The serial clock terminals SCL of the sensor circuits 50A to 50D are commonly connected to a serial clock line 53, and the serial data terminals SDA are commonly connected to a serial data line 54. A microcomputer 52 is installed on a PCB substrate outside the glass substrate 200. A gap between the microcomputer 56 and the sensor circuits 50A and 50D is configured so that data communication may be made attainable through the serial clock line 53 and the serial data line 54. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
