摘要： 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 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. The PAM data voltage is applied at once to the plurality of pixels included in the display panel. The driving circuit is configured to control a grayscale of a light emitted by the inorganic light emitting device by controlling a pulse width of a driving current having an amplitude corresponding to the applied PAM data voltage based on the applied PWM data voltage.
