A liquid-crystal-display television (LCD TV) is a television set that uses a liquid-crystal display to produce images. It is by far the most widely produced and sold type of television display. LCD TVs are thin and light, but have some disadvantages compared to other display types such as high power consumption, poorer contrast ratio, and ...
A liquid-crystal display ( LCD) is a flat-panel display or other electronically modulated optical device that uses the light-modulating properties of liquid crystals combined with polarizers. Liquid crystals do not emit light directly [1] but instead use a backlight or reflector to produce images in color or monochrome.
A flat-panel display ( FPD) is an electronic display used to display visual content such as text or images. It is present in consumer, medical, transportation, and industrial equipment. Flat-panel displays are thin, lightweight, provide better linearity and are capable of higher resolution than typical consumer-grade TVs from earlier eras.
Major technologies are CRT, LCD and its derivatives ( Quantum dot display, LED backlit LCD, WLCD, OLCD), Plasma, and OLED and its derivatives (Transparent OLED, PMOLED, AMOLED). An emerging technology is Micro LED and cancelled and now obsolete technologies are SED and FED .
Liquid-crystal-display televisions (LCD TV) are television sets that use liquid-crystal displays to produce images. LCD televisions are much thinner and lighter than cathode ray tube (CRTs) of similar display size and are available in much larger sizes (e.g., 90-inch diagonal).
A 140 cm (56 in) DLP rear-projection TV. Large-screen television technology (colloquially big-screen TV) developed rapidly in the late 1990s and 2000s. Prior to the development of thin-screen technologies, rear-projection television was standard for larger displays, and jumbotron, a non-projection video display technology, was used at stadiums ...
An LED-backlit LCD is a liquid-crystal display that uses LEDs for backlighting instead of traditional cold cathode fluorescent (CCFL) backlighting. LED-backlit displays use the same TFT LCD (thin-film-transistor liquid-crystal display) technologies as CCFL-backlit LCDs, but offer a variety of advantages over them.
As of 2017, the most common aspect ratio for TV broadcasts is 16:9, whereas movies are generally made in the wider 21:9 aspect ratio. Most modern TVs are 16:9, which causes letterboxing when viewing 21:9 content, and pillarboxing when viewing 4:3 content such as older films or TV broadcasts, unless the content is cropped or stretched to fill ...
1080p progressive scan HDTV, which uses a 16:9 ratio. Some commentators also use display resolution to indicate a range of input formats that the display's input electronics will accept and often include formats greater than the screen's native grid size even though they have to be down-scaled to match the screen's parameters (e.g. accepting a 1920 × 1080 input on a display with a native 1366 ...
The term has been used since at least 1933; [1] in more recent times, it refers to the generation following standard-definition television (SDTV). It is currently the standard video format used in most broadcasts: terrestrial broadcast television, cable television, satellite television .
