A plasma display is a type of flat panel display common to large TV displays 30 inches (76 cm) or larger. They are called "plasma" displays because they use small cells containing electrically charged ionized gases, which are plasmas.
Capable of producing deeper blacks allowing for superior contrast ratio. Wider viewing angles than those of LCD images do not suffer from degradation at less than straight ahead angles like LCDs.
Less visible motion blur, thanks in large part to very high refresh rates and a faster response time, contributing to superior performance when displaying content with significant amounts of rapid motion.
Less expensive for the buyer per square inch than LCD, particularly when equivalent performance is considered.
