quality.
1-3. STRUCTURE AND PRINCIPLE OPERATION OF PLASMA DISPLAY
In a Plasma Display TV, Row and Column electrodes are placed between two glass substrates. A rare gas is then filled between each substrate. When a
high voltage is applied to these electrodes, the gas is activated resulting in the radiation of ultraviolet light, similar to the operation in fluorescent lamps.
These ultraviolet rays then activate phosphor that has been coated on the inside of the glass substrate, and visible light is emitted from the panel.
