Currently there are three technologies being used to create high-definition flat panel displays. These displays contain two mechanisms, one that generates light, and one that manipulates light to create images. In a PDP display, visible light generation and manipulation occur through the stimulation of phosphors by ultraviolet light. Essentially, when ultraviolet light strikes the phosphorus they produce visible light. Full-color operation will be discussed later, for now let us focus on creating grayscale images.
