What is a light valve?
The light valve is a device that either reflects light or allows you to pass through the shutter. The light valves have a wide range of uses from television files to top secret military applications. The light valve can be either a liquid crystal (LC) or a nanomechanical device. Nanomechanical devices include digital micromirror devices (DMD) and grid light valve (GLV). LCS remained a little more than the novelty until 1969, when important steps to commercially viable material were carried out. The LC feature that allows them to function as light valves is their ability to polarize light. LCs are used with a polarizer that either allows you to pass or reflect it, according to its polarity. The electric current applied to the device is determined by the polarity. And some of his postgraduate students. One of the students of Bloom, Raj Apte, outlined the potential commercial viability of this technology in his doctoral thesis of 1994. Bloom founded a start company in STEyear to commercialize this technology. GLV devices are mechanical grids that module the amount of diffraction light when they meet them. These devices are located in TV files and are also used in military, technologies and industrial applications.
DMD was created by Texas Instruments in 1987 under the leadership of Larry Hornbeck. The original concepts were aimed at detecting military objects such as tanks and armored personnel carriers during supervision. DMD is a light valve consisting of fields of up to 1.3 million microscopic mirrors mounted on the hinge. Each chip corresponds to one pixel on the screen and everyone can either be turned off or on, light transmission or ReflexeG IT. Many applications such as TV, domestic cinema systems and business videos projectors use one chip system combined with color bikes and speed and duration of time PThere are every color, coordinated by the color to be displayed.
The very high image quality requires three DMD units chip. One chip is used for each primary color, with the same effect as the One Chip system. These very top units are used in film theaters, in some TVs and some military environments, where a very high resolution is needed. DMDs have a much faster response time than LCS, but are measurably slower than GLV.
