front-projection (with reflective screen) e.g. video projector: reflective mode of operation rear-projection (with transmissive screen) e.g. rear projection television screen: transflective mode of operation (e.g. transflective LCD) retinal projection (with or without combiner) e.g. head mounted display
Electrically operated display devices have developed from electromechanical systems for display of text, up to all-electronic devices capable of full-motion 3D color graphic displays. Electromagnetic devices, using a solenoid coil to control a visible flag or flap, were the earliest type, and were used for text displays such as stock market ...
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 and concerts.
The 2.1-inch Epson ET-10 [18] Epson Elf was the first color LCD pocket TV, released in 1984. [19] In 1988, a Sharp research team led by engineer T. Nagayasu demonstrated a 14-inch full-color LCD, [12] [20] which convinced the electronics industry that LCD would eventually replace CRTs as the standard television display technology. [12]
A thin-film-transistor liquid-crystal display (TFT LCD) is a type of liquid-crystal display that uses thin-film-transistor technology to improve image qualities such as addressability and contrast. [1]
In 2008, LCD TV shipments were up 33 percent year-on-year compared to 2007 to 105 million units. [10] In 2009, LCD TV shipments raised to 146 million units (69% from the total of 211 million TV shipments). [11] In 2010, LCD TV shipments reached 187.9 million units (from an estimated total of 247 million TV shipments). [12] [13]
With the trend toward large-screen television technology, the 32-inch (81-cm) screen size was rapidly disappearing by mid-2009. 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.
Electronic paper displays which can be rolled up have been developed by E Ink. At CES 2006, Philips showed a rollable display prototype, with a screen capable of retaining an image for several months without electricity. In 2007, Philips launched a 5-inch, 320 x 240-pixel rollable display based on E Ink’s electrophoretic technology.
