    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.

    Abstract: A method of fabricating a semiconductor memory device includes alternately and repeatedly stacking sacrificial layers and insulating layers on a substrate, forming an active pattern penetrating the sacrificial layers and the insulating layers, continuously patterning the insulating layers and the sacrificial layers to form a trench, removing the sacrificial layers exposed in the trench to form recess regions exposing a sidewall of the active pattern, forming an information storage layer on the substrate, forming a gate conductive layer on the information storage layer, such that the gate conductive layer fills the recess regions and defines an empty region in the trench, the empty region being surrounded by the gate conductive layer, and performing an isotropic etch process with respect to the gate conductive layer to form gate electrodes in the recess regions, such that the gate electrodes are separated from each other.

    Abstract: In a display apparatus, a display panel includes a pixel array of pixels, each pixel disposed on one of a plurality of row lines and including a plurality of inorganic LEDs, and a sub pixel circuit corresponding to each of the plurality of LEDs. Each sub pixel circuit includes a PMOSFET driving transistor, and drives a corresponding LED based on an applied image data voltage. A sensing part senses a current through the driving transistor of at least one sub pixel circuit based on a specified voltage applied to the sub pixel circuit, and outputs corresponding sensing data. A correcting part corrects an image data voltage applied to the sub pixel circuit based on the sensing data. In each LED, an anode electrode is coupled to a common node to which a driving voltage is applied, and a cathode electrode is coupled to a source terminal of the driving transistor.
