Abstract:
1. An electro-optic device comprising: a temperature sensor that includes a plurality of dummy pixel electrodes electrically interconnected to each other on an outside of a display region for displaying an image; a measurement unit that measures a temperature by applying, at a set time interval, a signal for actuating the temperature sensor to the temperature sensor through a wiring; a first setting unit that sets the set time interval as a second time interval which is longer than a first time interval, if a difference between a latest temperature measured by the measurement unit and a previous temperature measured by the measurement unit at a time period preceding the latest temperature is less than a first predetermined threshold value as determined by a control unit, when the measurement unit measures the temperature at the first time interval; and a second setting unit that sets the set time interval as the first time interval, if an amount of incident light from a light source is changed when the measurement unit measures the temperature at the second time interval.
