Frank look at this below:
“Liquid crystal on silicon, or LCoS, technology, is a technology that’s pretty simple to describe, and the concept has been known for quite a while. The concept is a combination of the liquid crystal display, very similar to that which you have in your laptop computer, and a complex integrated circuit similar in transistor count to the Pentium IV microprocessor. It’s a combination of those two technologies together that creates this LCoS device, and I’ll try to describe how that actually works. This device is about a half-inch on its side, so it’s a relatively small device. In that device are over one million individual picture elements. Each one of those picture elements is represented by an individual transistor on this integrated circuit. If you think about a little integrated circuit about a half-inch square with lots and lots of individual transistors sitting on the surface of it, on top of that, we put a mirror, an aluminum mirror, and on top of that we put some liquid crystal, which, for all intents and purposes, looks like water. We capture that and put a cover plate over it. When one of those transistors is energized, it changes the state of the liquid crystal. When it’s projected through the rest of the optical system, it tenuates the light with that particular little picture element according to how much energy we put in the transistor. We have the capability then by controlling each individual transistor to control the amount of light coming from each little pixel element in this device. The result is when you put all those transistors together, you have the ability to create a picture with an electronic signal in it, very much like an image on your laptop computer, except obviously much smaller and with much higher resolution. When we get done with this, what we have is a little device a half-inch on the side that creates this very high resolution picture in black-and-white — but that’s not particularly useful. So what we need to do is to put that in the equivalent of a slide projector or something that will optically project that image up onto a large screen. And we do that, using three of those little devices, one for each TV color — red, green and blue — through what is the equivalent of a slide projector for this little electronic slide that we’ve created. In this fashion, we are able to create very high resolution images on a large-scale. The initial market that we see for this product is in rear-projection television sets. For example, we’re looking at 52-inch rear projection television sets using this light engine to project that image. Using this technology, SpatiaLight now has the potential of creating an image of very high quality, capable of meeting the High Definition Television, or HDTV, signal requirements, with a truly outstanding picture. If you had a chance to see this, you would readily recognize the dramatic improvement in picture quality.”
The above information would make what you previously said appear to be correct, but now read this.
Most microdisplays use a silicon chip as the substrate material. The chip also houses the addressing electronics (at least an active matrix with integrated drivers), usually implemented in standard CMOS technology. This mature technology generates very reliable and stable circuits (better than TFT technology) and allows very small pixel pitches (down to 10 µm or even somewhat smaller) and high display resolutions.
Microdisplays can be used in projectors or in "near to the eye" (NTE) applications, such as in head-mounted displays and camera view-finders.
Several electro-optical effects can be used to generate the image: Electroluminescence (EL), OLED, vacuum fluorescence (VF), reflective Liquid Crystal effects and tilting or deforming of micro-mirrors (requires micro-machining). The most popular combinations today are Liquid Crystal On Silicon (LCOS), OLED on silicon and tilted mirrors (DMD).
It appears that Ah is correct. There is more to this than it being another form of projection. Also read this clip below. Sounds like a better idea than iFire in many aspects.
The new SpatiaLight ImagEngine 1280BC has 1280 columns by 1024 rows (1,310,720 pixels), a higher resolution than the previous generation LCOS microdisplays (1024 x 768 resolution), commonly available from other manufacturers. The SpatiaLight ImagEngine 1280BC provides the display capability to put bright, high-contrast images on both front and rear projection screens at a reasonable price. Chuck McLaughlin, President, McLaughlin Consulting Group, which tracks markets, products and technology for microdisplays and projectors, said, "Driven by the sustained growth of the PC market, we expect to see the worldwide monitor and display market continue to grow in excess of 15% a year from its current size of 125 million units valued at more than $50 billion to in excess of 300 million units and $85 billion in 2005. Growth in television sales will also be strong at about 5% annually from the current market base of 130 million units valued at $60 billion.''
Any thoughts are welcome?
