Infrared radiation spectrum of alternating current plasma display panels

To optimize cell structure and driving voltage of alternating current plasma display panel (AC PDP), the effects of electrode structure parameters, new-type cell configuration with floating electrodes, and sustained voltage pulse parameters on infrared-radiation spectrum from Ne-Xe mixture gas discharge were experimentally studied by using a spectrum measuring system and a macroscopic AC plasma display panel cell. The results show that as the sustaining electrode width increases, the 828 nm infrared radiation from a macroscopic cell is enhanced, while its radiation efficiency almost keeps constant. As the sustaining electrode gap increases or a floating electrode with appropriate width is inserted between two sustaining electrodes, both the intensity and efficiency of 828 nm radiation are improved. Increasing the frequency or amplitude of sustained voltage can enhance 828 nm radiation, but its radiation efficiency will drop.
