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 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.

Abstract: A display panel includes a driving circuit layer disposed on a glass that includes a first driving circuit and a second driving circuit, and an inorganic light emitting device mounted on the driving circuit layer to be electrically connected to the first driving circuit. The inorganic light emitting device includes a sub pixel of the display panel. The first driving circuit is located in an area where the inorganic light emitting device is mounted, while the second driving circuit is arranged in an area excluding an area in which the first driving circuit is arranged in the driving circuit layer. The second driving circuit generates a control signal for driving the first driving circuit and provide the generated control signal to the first driving circuit.

Abstract: A display panel includes a glass, an inorganic light emitting device included in a sub pixel of the display panel, and a driving circuit disposed between the glass and the inorganic light emitting device such that the inorganic light emitting device is mounted on and electrically connected to the driving circuit. The driving circuit is configured to control an amplitude and a pulse width of a driving current provided to the inorganic light emitting device. The amplitude and pulse width of the driving current may be corrected according to a deviation in the driving circuit.
