A plasma display (or PDP) is made up of small cells containing electrically charged ionized gases. Plasma televisions are generally large and are capable of producing deeper blacks giving a better, more accurate picture.
Plasma television screens have a wider viewing angle than LCD television screens allowing for more people to watch the television from wider angles. Plasma screens also have less visible motion blur than most television screens that were sold when plasma televisions were popular. This is due to a superior refresh rate and a faster response time than the other types of televisions on the market.
Plasma television sets are notorious for their weight. This is because Plasma screens used glass panels whereas LCD screens generally used plastic panels. Because of the glass panel, plasma televisions were more likely to break when being transported or moved. Some glass panels were 1/4 of an inch which added to the weight of the television greatly. Plasma televisions also ran hotter than LCD televisions of the time, causing damage to components later on in the televisions life time.
