Drive circuit, optoelectronic device, electronic device, and drive method

摘要

A device includes pixel circuits arranged in columns and rows, n data lines (n being an integer of 2 or more) for each column, gate lines supplied with scan signals, and light-emitting control lines supplied with light-emitting control signals. The pixel circuits are divided into n groups of rows, each group of rows being exclusively connected to a corresponding data line. Each pixel circuit includes a write control transistor to control writing a data voltage in response to a scan signal, a driving transistor to control the amount of current to be supplied to a current light-emitting element, a light-emitting control transistor to control supply of a current to the light-emitting element in response to a light-emitting control signal, a capacitor to retain a voltage corresponding to a write data voltage, and a reset transistor to set the gate electrode of the driving transistor with the initial voltage.
