PROBLEM TO BE SOLVED: To reduce power consumption.SOLUTION: An input circuit includes: a selection signal output circuit for outputting a selection signal; a reset signal output circuit for outputting a reset signal; and a light detection circuit which receives the input of the selection signal and reset signal, is brought in to a reset state in accordance with the inputted reset signal, and after incidence of light, generates a voltage with a value corresponding to the illuminance of the incident light, and outputs the generated voltage as a data signal in accordance with the inputted selection signal. In a first period, the reset signal output circuit outputs the reset signal, the selection signal output circuit outputs the selection signal, and thereby the light detection circuit outputs the data signal. In a second period, the output of the reset signal from the reset signal output circuit and the output of the selection signal from the selection signal output circuit are stopped. |
