Liquid Crystal on Silicon (LCoS) Technology

By admin | January 18, 2010

A liquid crystal on silicon (LCOS) technology is a hybrid technology, which is typically used in projection televisions today, is a form of micro-projection or micro-display in hyper-luminous display, which translates into time LCD. The problem with CRT that most of us know that is a clear image to be displayed in so far as to obtain a clear signal, even if their performance is limited by the size of the screen. This works well only up to 40 inches afterSeveral other new technologies such as digital light processing (DLP), liquid crystal display (LCD) and liquid crystal on silicon (LCOS) to take over.

Very similar to conventional DLP projectors, LCOS is basically a reflective technology, but the liquid crystals used instead of individual mirrors. When analyzed relative, LCD projectors use transmissive LCD chips, which can be easy to move out of liquid crystals to give. In LCOS, a silicon chip, originallycovered with a layer of aluminum with some types of passive film, which is highly reflective in nature, used in conjugation with liquid crystals.

Traditionally, a liquid crystal sandwiched between two sheets of glass of a unit of LCD. Almost all liquid crystal displays sold in the same way. They are also placed between crossed polarizer for direct vision.

Even so, the production is a problem when high resolution is neededthe fastest computers as thin film transistor (TFT) technology, commonly used in the manufacture of high-resolution screen, as a ground layer of the stack of material on a piece of glass, along with thousands of transistors, which had to be very costly means the end , making the technique impractical for commercial production.

And 'here LCOS technology comes into play, as an alternative method for high-resolution images using liquid crystals' impliesA liquid crystal on silicon technology. LCOS uses a single glass substrate, which is polished with silicon on the back of the screen. Silicon technology has advanced to a point, the inclusion and modeling of millions of pixels is done on a very small area, say two or three centimeters. Then a layer of reflective layer of aluminum applied to the pixel with polyimide alignment layer. Therefore, the liquid crystal on silicon technology (LCOS), a high resolution monitor micro economicfor commercial production, and also easy to produce for manufacturers around the world.

Now it is known that the LCOS technology is generally higher resolution images and higher contrast than traditional LCD and plasma screens which is more convenient for the implementation of such devices as televisions plastic.

In 2004, during a major technology event in the United Kingdom, many rolled silicon chip giant plans for largemass production of good LCOS chips used in flat-screen TV-viewing experience of an ordinary man on a revolution much lower price.

And now, compared to DLP and LCD systems in terms of price and performance LCOS technology is not only beautiful but very strong, sometimes also useful that the excellent color reproduction, stunning contrast ratio, high resolution, "brings screen "power, and no screen burn-in problems compared to the LCD. PixelLCOS displays can be made much smaller than what is possible with most other micro-projection technology without compromising the image quality and maneuverability. LCOS displays can be a very high resolution like 1920×1080 and 1600×1200 and more reduced, without increasing the size and price of flat panel display units.
