Miracast is utilised in many devices and is used or branded under various names by different manufacturers, including Smart View (by Samsung), [3] [4] SmartShare (by LG), screen mirroring (by Sony), Cast (in Windows 11) and Connect (in Windows 10), wireless display and screen casting.
An LCD projector is a type of video projector for displaying video, images or computer data on a screen or other flat surface. It is a modern equivalent of the slide projector or overhead projector .
Active displays Passive displays present visual information by emitting light present visual information by modulating light Principle Liquid crystal display (LCD) + backlight (this combination is considered an active display) LCD Example LCD TV screen, LCD computer monitor LCD watch (reflective) see LCD classification Principle Cathodoluminescence
The diagram shows the mirror system and the synchronized engine that displays light from the high speed video projector. Spinning mirror systems are used to build interactive 3D graphics and autostereoscopic visuals visible to multiple simultaneous viewers, since a different view can be perceived by each viewer depending on the angle of vision.
In 2003 Keigo Iizuka discovered an inexpensive implementation of this principle on laptop computer displays using cellophane sheets. [6] One can construct a low-cost polarized projection system by using a computer with two projectors and an aluminium foil screen. The dull side of aluminium foil is brighter than most silver screens.
Some older LCD projectors have a more noticeable screen-door effect than first generation DLP projectors. [2] Newer DLP chip designs promise closer spacing of the mirror elements which would reduce this effect; [citation needed] however, some space is still required along one edge of the mirror to provide a control circuit pathway. Use of ...
The technology goes back to 1973 with Harvey C. Nathanson's (inventor of MEMS c. 1965) use of millions of microscopically small moving mirrors to create a video display of the type now found in digital projectors. [1] The project at Texas Instrument's began as the deformable mirror device in 1977 using micromechanical analog light modulators.
A speaker giving a presentation with an RF pointer in his left hand. Using a wireless clicker, helps the presenter to move freely, instead of being obliged to stay next to the computer, can get closer and keep in touch with the audience, watching the presentation together with them, being able to use the built-in laser pointer, in order to emphasize specific points in the dialogue with the ...
