![]() ![]() As they use the same or similar phosphors as are used in CRT displays, plasma's color reproduction is very similar to that of CRTs.Capable of producing deeper blacks than LCD allowing for a superior contrast ratio.Plasma display advantages and disadvantages įurther information: Comparison of CRT, LCD, Plasma, and OLED Advantages Though considered bulky and thick compared with their LCD counterparts, some sets such as Panasonic's Z1 and Samsung's B860 series are as slim as 2.5 cm (1 in) thick making them comparable to LCDs in this respect.Ĭompeting display technologies include cathode-ray tube (CRT), organic light-emitting diode (OLED), CRT projectors, AMLCD, Digital Light Processing DLP, SED-tv, LED display, field emission display (FED), and quantum dot display (QLED). ![]() With the trend toward large-screen television technology, the 32 inch screen size was rapidly disappearing by mid-2009. Although a few companies have been able to make plasma enhanced-definition televisions (EDTV) this small, even fewer have made 32 inch plasma HDTVs. Plasma display panels cannot be economically manufactured in screen sizes smaller than 82 centimetres (32 in). Plasma screens are made out of glass, which may result in glare on the screen from nearby light sources. This is the estimated time over which maximum picture brightness degrades to half the original value. The lifetime of the latest generation of plasma displays is estimated at 100,000 hours (11 years) of actual display time, or 27 years at 10 hours per day. Most screens are set to "vivid" mode by default in the factory (which maximizes the brightness and raises the contrast so the image on the screen looks good under the extremely bright lights that are common in big box stores), which draws at least twice the power (around 500–700 watts) of a "home" setting of less extreme brightness. Typical power consumption is 400 watts for a 127 cm (50 in) screen. The plasma that illuminates the screen can reach a temperature of at least 1,200 ☌ (2,190 ☏). Power consumption varies greatly with picture content, with bright scenes drawing significantly more power than darker ones – this is also true for CRTs as well as modern LCDs where LED backlight brightness is adjusted dynamically. The display panel itself is about 6 cm (2.4 in) thick, generally allowing the device's total thickness (including electronics) to be less than 10 cm (3.9 in). (As plasma panels are locally lit and do not require a back light, blacks are blacker on plasma and grayer on LCD's.) LED-backlit LCD televisions have been developed to reduce this distinction. They had a very low luminance "dark-room" black level compared with the lighter grey of the unilluminated parts of an LCD screen. Plasma displays are bright (1,000 lux or higher for the display module), have a wide color gamut, and can be produced in fairly large sizes-up to 3.8 metres (150 in) diagonally. Plasma displays are obsolete, having been superseded in most if not all aspects by OLED displays. Manufacturing of plasma displays for the United States retail market ended in 2014, and manufacturing for the Chinese market ended in 2016. By 2013, they had lost nearly all market share due to competition from low-cost LCDs and more expensive but high-contrast OLED flat-panel displays. Until about 2007, plasma displays were commonly used in large televisions. Panasonic plasma TV of the last generation. Plasma televisions were the first large (over 32 inches diagonal) flat panel displays to be released to the public. A plasma display panel ( PDP) is a type of flat panel display that uses small cells containing plasma ionized gas that responds to electric fields. ![]()
