Classification: CPC G | IPC G

Claim 14:
15. A method of controlling a display apparatus including a display panel, wherein the display panel comprises:
a pixel array, in which pixels composed of a plurality of inorganic light-emitting elements of different colors are arranged in a matrix form, and a pixel circuit that is provided for each of the plurality of inorganic light-emitting elements, and the pixel circuit controlling, based on an applied image data voltage, a duration and a magnitude of a driving current provided to the inorganic light-emitting elements,
wherein the method comprises:
sensing, based on a voltage applied to the pixel circuit, a current flowing through a driving transistor included in the pixel circuit;
correcting, based on sensing data corresponding to the sensed current, the image data voltage applied to the pixel circuit; and
controlling the magnitude of the driving current based on a constant current generator data voltage,
wherein the image data voltage comprises the constant current generator data voltage.
