The lifetime of the latest generation of plasma displays is estimated at 100 000 hours of actual display time, or 27 years at 10 hours per day. This is the estimated time over which maximum picture brightness degrades to half the original value, not catastrophic failure. [4]
Plasma displays also have their drawbacks. They are often criticized for reflecting more ambient light than LCD displays. The screen is made from glass, which reflects more light than the material used to make an LCD screen, which creates a glare. Companies such as Panasonic coat their newer plasma screens with an anti-glare filter. Plasma panels currently cannot be made in screen sizes smaller than 32″. Although few companies have been able to make plasma EDTVs this small, even fewer have made 32″ plasma HDTVs. The 32″ screen size is also “going extinct”. Plasma displays are also considered bulky and thick (usually six inches in depth) compared to their LCD conterparts, although 2009 high-end displays, such as Panasonic’s Z1 and Samsung’s B860 series can as slim as one inch thick. Plasma displays also tend to consume more electricity than LCD displays. Panasonic aims to solve this dilemma by using Neo-PDP screens for their 2009 series of Viera plasma HDTVs. Panasonic states that the PDPs will consume half the power of the previous series to achive the same overall brightness.
Competing displays include the CRT, OLED, AMLCD, DLP, SED-tv, LED, and field emission flat panel displays. Advantages of plasma display technology are that a large, very thin screen can be produced, and that the image is very bright and has a wide viewing angle. The viewing angle characteristics of plasma displays and flat-face CRTs are essentially the same, topping all LCD displays, which have a reduced viewing angle in at least one direction. Plasma TVs also do not exhibit an image blur common in many LCD TVs. televisions
