Abstract: An optoelectronic device includes a driving transistor, a correction transistor, and a control circuit. The driving transistor adjusts a first current from a power supply based on a voltage stored in a first capacitor. The driving transistor supplies the adjusted first current to the light-emitting element. The correction transistor is electrically connected on a path of a second current flowing from the power supply to the first capacitor, and adjusts the second current based on a voltage stored in a second capacitor. The control circuit controls the second capacitor to store a gray scale voltage while the first current flows, and controls flow of the second current to update the voltage stored in the first capacitor while the first current is blocked.
