8. Color trailing effect of phosphors
8.1 Phosphor response time
The principle behind color plasma screens is based on the use of three chemical compounds called phosphors or luminophores, which are excited by ultraviolet radiation from the gas discharge. Each phosphor, by virtue of its chemical composition, then emits a specific wavelength. The three wavelengths chosen to render colored images are blue, red and green.
Currently, one of the main problems with plasma screens is their lifespan, expressed in terms of luminous marking. Indeed, if a certain image is repeatedly projected onto the screen (e.g. DVD menu), certain phosphors will deteriorate more rapidly, losing their luminous yield more quickly than others. As a result, the screen will no longer be...
