Plasma display
Plasma display panel (PDP) is a type of flat panel display common to large TV Plasma display 30 inches (76 cm) or larger. They are called “Plasma display because the technology utilizes small cells containing electrically charged ionized gases, or what are in essence chambers more commonly known as fluorescent lamps.
Plasma display are bright (1,000 lux or higher for the module), have a wide color gamut, and can be produced in fairly large sizes—up to 150 inches (3.8 m) diagonally. They have a very low-luminance “dark-room” black level compared to the lighter grey of the unilluminated parts of an LCD screen (i.e. the blacks are blacker on plasmas and greyer on LCDs).[1] LED-backlit LCD televisions have been developed to reduce this distinction.
Plasma display
The display panel itself is about 6 cm (2.5 inches) thick, generally allowing the device’s total thickness (including electronics) to be less than 10 cm (4 inches). Plasma displays use as much power per square meter as a CRT or an AMLCD television.[citation needed] Power consumption varies greatly with picture content, with bright scenes drawing significantly more power than darker ones – this is also true of CRTs. Typical power consumption is 400 watts for a 50-inch (127 cm) screen. 200 to 310 watts for a 50-inch (127 cm) display when set to cinema mode. Most screens are set to ‘shop’ mode by default, which draws at least twice the power (around 500–700 watts) of a ‘home’ setting of less extreme brightness.[2]
Plasma display
Panasonic has greatly reduced power consumption (“1/3 of 2007 models”) [3][4] Panasonic states that PDPs will consume only half the power of their previous series of plasma sets to achieve the same overall brightness for a given display size. 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.[5]
Plasma display screens are made from glass, which reflects more light than the material used to make an LCD screen.[citation needed] This causes glare from reflected objects in the viewing area. Companies such as Panasonic coat their newer plasma screens with an anti-glare filter material.[citation needed] Currently, plasma panels cannot be economically manufactured in screen sizes smaller than 32 inches. Although a few companies have been able to make plasma Enhanced-definition televisions (EDTV) this small, even fewer have made 32in plasma HDTVs. With the trend toward large-screen television technology, the 32in screen size is rapidly disappearing. Though considered bulky and thick compared to their LCD counter parts, some sets such as Panasonic’s Z1 and Samsung’s B860 series are as slim as one inch thick making them comparable to LCDs in this respect.
