How do plasma displays work to produce light

WebWhen current flows, the gas in the cell ionises to a plasma state, and as a result of this, UV light is emitted. The phosphor coating the walls of the cell absorbs this UV light and is stimulated to emit visible light, either red, green or blue. How many pixels a plasma display has depends on the resolution of the display. WebPlasma displays use millions of small cells that contain electrically charged ionized gases.

WebA plasma display is also composed of pixels. Instead of electrons coming from a beam and striking the screen, you excite part of the gas mixture in each pixel to emit a UV (ultraviolet) photon (i.e., radiation, but you can't see it), which in turn excites the phosphor pixel and causes to emit light in the visible (where our eyes can see).
