Abstract: An electroluminescent display and a method of driving the same are disclosed. The electroluminescent display includes a driving transistor configured to generate a driving current depending on a gate-source voltage, a storage capacitor configured to store a data voltage and provide the stored data voltage to a gate electrode of the driving transistor, a first switching transistor configured to control a gate potential of the driving transistor, a second switching transistor configured to control a source potential of the driving transistor, a light emitting diode configured to emit light in response to the driving current generated from the driving transistor, and a third switching transistor configured to electrically float a source electrode of the driving transistor and an anode electrode of the light emitting diode when one of the first and second switching transistors is turned off

Abstract: The present disclosure relates to a large area ultra high density flat panel display having a high aperture ratio. The present disclosure provides a flat panel display including a driving current line and a sensing line disposed in a first direction on a substrate; a scan line and a sensing gate line disposed in a second direction on the substrate; a horizontal current line disposed at upper side of the scan line in the second direction and connected to the driving current line; a horizontal sensing line disposed at lower side of the sensing gate line in the second direction and connected to the sensing line; a common current line branched from the horizontal current line and crossing the scan line; and a first pixel area and a second pixel area disposed between the driving current line and the sensing line as having a bi-symmetric shape with each other based on the common current line.

Abstract: The present disclosure relates to an ultra high density transparent flat panel display. The present disclosure provides a transparent flat panel display including: a driving current line, a data line and a sensing line running in a vertical direction on a substrate; a scan line and a horizontal sensing line running in a horizontal direction on the substrate; an emission area disposed between the driving current line and the data line; and a transparent area disposed between the data line and the sensing line.
