Abstract
An optoelectronic device includes a first transistor, a second transistor, and a control circuit. The first transistor is electrically connected between a power supply and a light-emitting element, has a gate to receive a gray scale voltage, and supplies the light-emitting element with a driving current corresponding to the gray scale voltage. The second transistor has a gate electrically connected to an electrode of the light-emitting element and a source or drain electrically connected to a circuit including a voltmeter. The control circuit reads a measurement value of the voltmeter when the gate of the first transistor receives the gray scale voltage, and corrects a next gray scale voltage applied to the gate of the first transistor based on the measurement value.
