Touch panel(1) senses the data inputted on screen to display, and analog/digital converting part(2) converts the analog signal of touch panel(1) to digital signal. Digitizer control part(3) computes the output of analog/digital converting part(2) to discriminate input data, and then it outputs a control signal. Serial communication part(4) transfers data to a main system through the control of digitizer control part(3), and power switching part(5) turn on/off the power supplied to touch panel(1) by the control of digitizer control part(3). |
