Abstract
In a display apparatus, a display panel includes a pixel array of pixels, each pixel disposed on one of a plurality of row lines and including a plurality of inorganic LEDs, and a sub pixel circuit corresponding to each of the plurality of LEDs. Each sub pixel circuit includes a PMOSFET driving transistor, and drives a corresponding LED based on an applied image data voltage. A sensing part senses a current through the driving transistor of at least one sub pixel circuit based on a specified voltage applied to the sub pixel circuit, and outputs corresponding sensing data. A correcting part corrects an image data voltage applied to the sub pixel circuit based on the sensing data. In each LED, an anode electrode is coupled to a common node to which a driving voltage is applied, and a cathode electrode is coupled to a source terminal of the driving transistor.
