Cathode potential controller, self light emission display device, electronic apparatus, and cathode potential controlling method

摘要

A cathode potential controller for controlling a common cathode potential applied to a self light emission type display panel in which an emission state of each of pixels is driven and controlled in accordance with an active matrix drive system, the cathode potential controller including: a self light emitting element; a constant current source; an electrode-to-electrode voltage measuring portion; a cathode potential determining portion; and a cathode potential applying portion.
