Abstract
A display panel includes sub-pixels each including a light-emitting element and a pixel circuit including a first transistor and a second transistor; a timing control unit to generate bias data based on first characteristic information of the first transistor, and generate correction data based on second characteristic information of the second transistor; and a data sensing driving unit configured to receive the bias data and the correction data, and output a bias voltage and a grayscale voltage to the pixel circuit. The pixel circuit includes the first transistor to output a driving current to the light-emitting element; a first driving circuit to control a magnitude of the driving current based on the bias voltage; and a second driving circuit including the second transistor and configured to control a pulse width of the driving current based on the grayscale voltage.
