Claim 0:
1. A display apparatus comprising:
a display panel including a pixel array, in which pixels that include 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 is configured to control, based on an applied image data voltage, a duration and a magnitude of a driving current provided to the inorganic light-emitting elements;
a sensor configured to sense, based on a voltage applied to the pixel circuit, a current flowing through a driving transistor included in the pixel circuit, and the sensor is configured to output sensing data corresponding to the sensed current; and
a corrector configured to correct, based on the sensing data, the image data voltage applied to the pixel circuit,
wherein the image data voltage comprises constant current generator data voltage, and
wherein the pixel circuit comprises:
a constant current generator circuit comprising a first driving transistor configured to control the magnitude of the driving current based on the constant current generator data voltage.
