Abstract
A method of measuring a panel current in an active matrix organic electroluminescence display panel, wherein when a current flowing through a display panel when one or a plurality of pixels are caused to emit light is measured, a flow-in current flowing into the display panel from a side of a high voltage and a flow-out current flowing out from the display panel toward a side of a low voltage are simultaneously measured, and a value of a panel current is determined using both obtained measurement results.
