Optical emission properties of a novel flat-panel fluorescent display are investigated by the Monte Carlo simulation. In the display device, phosphor films are excited by gallium nitride (GaN)-based micro-ultraviolet-(UV)-light-emitting diodes (LEDs). The GaN micro-UV-LEDs are adhered to the front surface of the phosphor films in this simulation. Fluorescent light emitted from the front surface of the film concentrates within a small area and the intensity is greater than that of the fluorescent light emitted from the back surface. Dependences of the emission intensities on other parameters are also evaluated. GaN micro-UV-LEDs which are transparent or have small areas comparable with the phosphor diameters are preferable for obtaining high resolution and high brightness.
