Abstract
A TFT element for ambient light detection and a TFT element for temperature detection are connected in series. In a first period, a first switch element is off, and a second switch element is at a hi side, so that a threshold voltage of the TFT element for temperature detection is detected. In a second period, a first switch element is on, and a second switch element is at a low side, so that temperature is detected. In a third period, a first switch element is on, and a second switch element is at a hi side, so that ambient light is detected. An input voltage and a control voltage to each of the TFT elements are set by a voltage controller provided in a drive circuit based on the threshold voltage.
