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.
scrcpy (short for "screen copy") is a free and open-source screen mirroring application that allows control of an Android device from a desktop computer. [2] The software is developed by Genymobile SAS, a company which develops Android emulator Genymotion. [3] The application primarily uses the Android Debug Bridge (ADB) via a USB connection to ...
It is also not possible to display multiple inputs at the same time. [18] Software-based PC & video-card controllers is a computer running an operating system (e.g., Windows, Linux, Mac) in a PC or server equipped with special multiple-output graphic cards and optionally with video capture input cards. These video wall controllers are often ...
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.
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.
Digital Micromirror Devices (DMD) were invented by Texas Instruments in 1987 and are the core of the DLP technology used for video projection. The mirrors are arranged in a matrix and have two states, "on" or "off" (digital). In the on state, light from the projector bulb is reflected into the lens making the pixel appear bright on the screen.

Also, the collisions of the laser photons with the phosphor screen do not produce x-rays as a side effect, whereas electrons colliding with a screen in a vacuum do produce x-rays, requiring radiation shielding in a CRT (said shielding taking the form of leaded glass in most CRTs produced since the early 1980s) but not in a LPD.
