Display panel and method for driving the display panel

A method for driving a display panel comprising a plurality of pixels respectively including a plurality of sub pixels arranged in a matrix form on a glass, wherein each of the plurality of sub pixels comprises:

• a driving circuit formed on the glass and configured to receive a pulse amplitude modulation (PAM) data voltage and a pulse width modulation (PWM) data voltage;
• and
• an inorganic light emitting device mounted on the driving circuit and configured to be electrically connected to the driving circuit, and to emit a light based on a driving current provided from the driving circuit,
• wherein the driving circuit comprises:
• a PAM driving circuit including a first driving transistor and configured to control an amplitude of the driving current based on the applied PAM data voltage;
• and
• a PWM driving circuit including a second driving transistor and configured to control a pulse width of the driving current based on the applied PWM data voltage,
• wherein the method comprises:
• based on the PAM data voltage being applied to the PAM driving circuit, compensating the applied PAM data voltage to the threshold voltage of the first driving transistor, and based on the PWM data voltage being applied to the PWM driving circuit, compensating the applied PWM data voltage to the threshold voltage of the second driving transistor;
• and
• based on the compensated PWM data voltage and the compensated PAM data voltage, providing, to the inorganic light emitting device, a driving current having an amplitude corresponding to the applied PAM data voltage and a pulse width corresponding to the applied PWM data voltage,
• wherein the PAM data voltage is applied at once to the plurality of pixels included in the display panel.
