LCoS

There is a lot of talk about LCOS technology presently. What is LCOS television technology? We can consider it as a hybrid between LCD and DLP technology. LCOS is reflective technology which uses liquid crystals that modulate the light to create the picture. In all three technologies, that is LCD, DLP and LCOS technology, lamps are used. The LCOS lamp longevity is approximately up to 6000 hours. Of course, this would depend on the number of hours of TV viewing. But you can get replacement lamps that will restore your LCOS TV to its original condition.

Among popular LCOS TV makes, Syntax LCOS TV is the most well known. Toshiba has launched a new model with LCOS 1:1 pixel mapping, which is as perfect as it can get. LCOS technology is also used in projectors. The Canon LCOS projector review cites it as one of the best suited for home theater system and the seamless pictures produced by it.

Sony LCOS televisions produce 1080p resolution, which is high definition at its best. The Sony LCOS systems are currently quite expensive compared to other brands. While comparing LCOS vs. LCD, the LCOS blacks are not as efficient as LCD or DLP. But the new Sony LCOS television is supposed to deliver excellent black levels with minimized video noise and various other features. Prices are also expected to come down.

With plasma versus LCOS, apart from being priced more reasonably, a plasma TV is much thinner and comes in many screen sizes. It is not surprising that consumers prefer to buy plasma or LCD compared to the traditional bulky TV or the relatively new LCOS technology TV.

Next comes the DILA LCOS from JVC. JVC has been making LCOS technology front projectors for several years now. But what is DILA LCOS? It is called Direct-drive Image light amplifier and also comes as HDILA. These are said to be comparable in terms of price with DLP and LCD TV and produce clear pictures. JVC also has 1080p HDILA TVs. Consumers had assumed that LCOS was phased out, but surprisingly it has come back with the advent of Sony LCOS TVs and JVC’s DILA. Another thing is the LCOS liquid crystal thickness that is about 4-5 micrometers. Sony has come up with LCOS systems that are as thin as 2 micrometers! It's not hard to see why LCOS technology is making a comeback rapidly.
