Virtual touch screen technology can also be applied to turn non-touch displays into interactive, touch-capable surfaces using a Kinect sensor in combination with a projector. [14] This type of application allows virtual touch technology to enhance personal display usage as well as better communication and presentation of data to be used in ...
Laser-powered phosphor display (LPD) is a large-format display technology similar to the cathode-ray tube (CRT).Prysm, Inc., a video wall designer and manufacturer in Silicon Valley, California, invented and patented [1] the LPD technology.
A touchscreen (or touch screen) is a type of display that can detect touch input from a user. It consists of both an input device (a touch panel) and an output device (a visual display). The touch panel is typically layered on the top of the electronic visual display of a device.
OmniTouch is a wearable computer, depth-sensing camera and projection system that enables interactive multitouch interfaces on everyday surface. Beyond the shoulder-worn system, there is no instrumentation of the user or the environment.
The shadow mask is installed to the screen using metal pieces [350] or a rail or frame [351] [352] [353] that is fused to the funnel or the screen glass respectively, [258] holding the shadow mask in tension to minimize warping (if the mask is flat, used in flat-screen CRT computer monitors) and allowing for higher image brightness and contrast.
A video projector is an image projector that receives a video signal and projects the corresponding image onto a projection screen using a lens system. Video projectors use a very bright ultra-high-performance lamp (a special mercury arc lamp ), Xenon arc lamp , metal halide lamp , LED or solid state blue, RB, RGB or fiber-optic lasers to ...
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.
An overhead projector projecting onto a pull-down screen. Pull-down screens (also known as manual wall screens) are often used in spaces where a permanently installed screen would require too much space. These commonly use painted fabric that is rolled in the screen case when not used, making them less obtrusive when the screen is not in use.
