DISPLAY DEVICE WITH TOUCH PANEL FUNCTION
First Claim
Patent Images
1. A display device with a touch panel function, comprising:
- a first sensor for detecting presence/absence of pressurization on an input screen;
a second sensor for detecting a contact position on said input screen, whose power consumption for waiting in a detectable state is higher than power consumption of said first sensor; and
a control unit for switching said second sensor into the detectable state when presence of pressurization is detected by said first sensor, whereinsaid input screen also serves as a display screen.

Abstract
A display device with a touch panel function includes a pressure sensor as a first sensor for detecting presence/absence of pressurization on an input screen, an electrostatic capacitance touch panel as a second sensor for detecting a contact position on the input screen, whose power consumption for waiting in a detectable state is higher than power consumption of the first sensor, and a control unit for switching the second sensor into the detectable state when presence of pressurization is detected by the first sensor. The input screen also serves as a display screen.
