How do Plasma Display Panels (PDP) work?
In a plasma display panel (PDP), a discharge space consisting of a phosphor layer sealed between two glass plates is filled with gas. When voltage is applied, it induces a plasma discharge, generating ultraviolet light. When the ultraviolet light strikes the three primary color RGB (red, green and blue) phosphors, the phosphors emit light in the three colors. In other words, a PDP displays images by making many tiny arrays of light-emitting “fluorescent lamps” flash at high speed in different colors (RGB). The gas is sealed in the discharge space between two glass plates and induces a plasma discharge towards the display electrodes, thus causing the arrays of phosphorous pixels in the discharge space to emit light. In a PDP, each pixel is made up of red, green and blue discharge tubes. The light emitted from each discharge tube due to the discharge plasma phenomenon is controlled to form an image on the screen.
