Abstract: An electroluminescent display device includes a display panel including a plurality of pixels each having a light emitting element and a driving thin film transistor for controlling a driving current flowing through the light emitting element and connected to a data line and a gate line, a panel driver connected to the data line and the gate line, and a timing controller configured to control an operation of the panel driver such that the operation is divided into an emission period in which the light emitting element emits light and a non-emission period in which light emission is stopped and to perform control such that a data voltage is input through the data line during the non-emission period and light emitting elements to which the data voltage is applied simultaneously emit light during the emission period.

Abstract: A white light emitting device, or more particularly an inverted white light emitting device, includes a plurality of stacks configured to emit white light, and an optical compensation layer provided at an outer surface of an electrode through which light is emitted to the outside. The configuration reduces the thickness of an electron transport layer adjacent to a cathode in the stack and therefore reduces the driving voltage and improves the viewing angle characteristics and as well as the efficiency.

Abstract: The present disclosure provides a light emitting display device including a low-level voltage power line configured to transmit a low-level voltage, a data line configured to transmit a data voltage, a gate line configured to transmit a gate signal, and a subpixel connected to the low-level voltage power line, the data line and the gate line. The subpixel includes a capacitor overlapping with the low-level voltage power line.
