Abstract(in English) Optical emission properties of the novel full-color flat-panel-display using a GaN micro UV-LED array are investigated by the Monte Carlo simulation, and device structures of the display that realize high resolution and high brightness are discussed. Phosphor particles having their diameters from 4 to 6μm are randomly arranged to form a phosphor film, and a GaN micro UV-LED as an excitation source is adhered to the front-side of the film. Transparent GaN UV-LEDs enable to utilize fluorescent light emitted from the front-side of the phosphor film of which intensity is about two times larger than that emitted from the backside. In addition, the front-side light concentrates in a small area whereas the backside light is widely dispersed. Dependencies of the properties on other parameters such as film thickness and LED areas are also discussed.
