Provided are an electroluminescenct (EL) device and an EL keypad employing the EL device, and more particularly, to an EL device and an EL keypad employing the EL device, which remove a process of manufacturing a separate EL device to prevent light leakage from occurring on the keypad of which the conventional EL device is used in cellular phones of the same kind due to numbers and characters variously changing according to manufacturers or countries where the cellular phones are put on the market, and form a printing layer on a transparent insulating substrate where an EL device portion is formed. In addition, an EL device and an EL keypad employing the same are provided, which remove a process of forming a printing layer and a plurality of keys on a separate insulating substrate and adhering the printing layer to the EL device, and form the printing layer and the plurality of keys on one transparent insulating substrate where the EL device portion is formed. The EL device includes: an insulating substrate; a printing layer formed on the insulating substrate; a transparent electrode layer formed on the printing layer; and an emitting layer, an insulating layer, a bottom electrode layer, and a protection layer sequentially formed on the transparent electrode layer. The EL keypad includes: an insulating substrate; a printing layer formed on one surface of the insulating substrate; a transparent electrode layer formed on the printing layer; an EL device including an emitting layer, an insulating layer, a bottom electrode layer, and a protection layer sequentially formed on the transparent electrode layer; a silicon layer formed on the protection layer; and a plurality of keys formed on the other surface of the insulating substrate.
Abstract:
A panel display using gold as a conductive element (30) and a matrix of carbon fibers (40) as emitters is presented. The invention provides a novel defined pixel width of three emitter fibers per cell wherein each cell is positioned within three emulsion layers of suspended nano-crystals stack positioned vertically atop one-another. Each of these respective layers is excited by a single carbon fiber. In the preferred embodiment, fiber length ends from each cell are positioned at the mid-point of each respective polymer layer thickness and produce one of red, green, or blue colors required to complete the image formation.

Abstract:
A thin-film phosphor layer can be formed by an improved deposition method involving: (1) forming a phosphor powder layer that is substantially uniformly deposited on a substrate surface; and (2) forming a polymer binder layer to fill gaps among loosely packed phosphor particles, thereby forming a substantially continuous layer of thin film.
Abstract:
Solution derived nanocomposite (SDN) precursor solutions are disclosed that comprise one or more metal precursors that are dissolved in a liquid comprising polar protic and polar aprotic solvents. The precursor solutions are characterized by the formation of a gel after a shear force is applied to the precursor solution or to a thin layer of precursor solution. Also disclosed are methods using such precursor solutions to make thin films, thin films made using the precursor solutions, thin films having a minimum surface area and devices containing thin films as disclosed herein.
