Abstract
The high-resolution image display device emits multicolored light from a monolithically integrated array. The monolithically integrated array has a transparent or at least translucent substrate. One side of the substrate carries semiconductor light emitting diodes or semiconductor laser diode devices emitting in the UV wavelength range. Many luminescence converting elements with luminescent substances of a predetermined color are applied to the substrate. The elements are optically separated from one another and associated with the semiconductor light emitting diode or semiconductor laser diode device. The elements receive the light emitted in the UV wavelength range by the semiconductor light emitting diode or semiconductor laser diode device, convert it into visible light, and emit the light in the visible spectrum.
