patentTecThe patented emissive projection display (EPD) has 2 major modules: A projector module that projects “latent” images of selective optical wavebands; and a novel transparent fluorescent screen module that converts the projected “latent” images to corresponding highly visible emissive images.

EPD combines the best of both conventional projection and emissive displays. Like projection, the screen has no pixel structures and can be produced roll-to-roll; it is scalable, portable, and adaptable to various display requirements. Like emissive displays (e.g. plasma), it has superior image quality and large viewing angles with the fluorescent screen.
