Display apparatus and control method therefor

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.
