fPLASMA DISPLAY PANELS (PDP)
Display types
What is Plasma?Plasma is often called the "Fourth State of Matter", the other three being solid, liquid and gas. A plasma is a distinct state of matter containing a significant number of electrically charged particles, a number sufficient to affect its electrical properties and behavior. In addition to being important in many aspects of our daily lives, plasmas are estimated to constitute more than 99 percent of the visible universe.
Plasma display panels:PLASMA display panels (PDPs) are one of the leading candidates in the competition for : large-size, high-brightness ,flat panel displays
suitable for high-definition television (HDTV) monitorsTheir advantages are:Fast response
Wide viewing angle
Low weight
Simple manufacturing process
High resolutionWORKING PRINCIPLE OF PLASMA DISPLAY PANELS:Typical plasma displays consist of two glass plates, each with parallel electrodes deposited on their surfaces. The electrodes are covered with a dielectric film. The plates are sealed together with their electrodes at right angles, and the gap between the plates is filled with an inert gas mixture. A protective MgO layer is deposited above the dielectric film. The role of this layer is to decrease the breakdown voltage caused by the high secondary electron emission coefficient of MgO.
The discharge is initiatedby applying a voltage pulse to the electrodes. Xenon gas mixtures are used to efficiently generate UV photons. The UV photonsemitted by the discharge hit the phosphors deposited onthe walls of the PDP cell and are converted into visible photons. Each cell contains phosphor that emits one primary color—red,green, or blue.
