Abstract: A display panel is provided. In the display panel, a plurality of pixels respectively including a plurality of sub pixels are arranged in a matrix form on a glass. Each of the plurality of sub pixels includes a driving circuit disposed on the glass and configured to receive a PAM data voltage and a PWM data voltage, and an inorganic light emitting device configured to emit a light based on a driving current provided from the driving circuit. The PAM data voltage is applied at once to the plurality of pixels included in the display panel. The driving circuit compensates a deviation between driving circuits included in each of the plurality of sub pixels based on a driving voltage of the driving circuit, and controls a pulse width of a driving current having an amplitude corresponding to the applied PAM data voltage based on the applied PWM data voltage.
