Abstract
An electro-optical device including at least one of an optical sensor and a temperature sensor, a pixel circuit and a control circuit is provided. The pixel circuit includes an OLED that emits light at brightness corresponding to a current flowing from an anode to a cathode, and a transistor that causes a current corresponding to a voltage between a gate node and a source node to flow through the OLED. The control circuit executes a reset operation or a non-reset operation in accordance with information that is a detection result of an optical sensor and information that is a detection result of a temperature sensor. The reset operation is an operation of supplying a predetermined potential to the anode via a data line. The non-reset operation is an operation of distributing an electric charge accumulated in the data line to the anode.
