What is LCoS Projector Technology?

LCOS stands for 'Liquid Crystal on Silicon' and is a typed digital image processing Chip that is able to produce Projector images that are superior to both LCD and DLP images. The problem is that LCoS Projectors are more expensive than either LCD or DLP projectors. The best LCoS Projectors are made by JVC and Sony. JVC produces LCoS projectors are branded 'D-ILA' which stands for 'Direct Drive Image Light Amplifier' and Sony LCoS brand 'SXRD' stands for 'Silicon X-tal Reflective Display'.

JVC and Sony are the leaders in LCoS Projector technology today and make the best projectors available for home theater use. JVC produced their first LCoS Projector way back in 1998 and Sony was not far behind. Both JVC and Sony make some beautiful 4K LCoS Projectors under the JVC D-ILA and Sony SXRD labels, and these beautiful projectors have become much more affordable today than they were just last year. Have a look at the range of LCoS Projectors on Amazon.Com USA website to compare prices.

Difference between LCos and LCD chips in Projectors

LCoS Chips are very similar to LCD chips. LCoS also uses LCDs to process the light signals, but reflects the processed light rather than letting light pass through the chip as in an LCD chip.

Because of this some call LCoS a 'Reflective LCD'. The DLP chip also uses a reflective technology. So LCoS can be considered as a combination of the two technologies: LCD and DLP.

LCoS Projectors work exactly like the 3LCD projectors but LCoS projectors use LCoS chips instead of LCD chips. LCoS projectors are considered to be the best home theater projectors and is the choice of many videophiles.

The picture projected by LCoS projectors are more like the movies shown in high class theaters and are very smooth with not even any hint of 'Screen Door' effect which some LCD projectors suffer from.

The chips in LCoS projectors are very difficult to manufacture. In fact Intel tried to develop a LCoS chip but gave up their efforts in the mid 2000s. LCoS chips are complicated because all the LCD control transistors and its circuitry are right under each LCD pixel of the LCoS Chip.

Since LCoS reflects the processed light signals, the control transistors do not come in the path of the light signals. Thus the pixels in an LCoS Chip are tightly packed together, to give a very smooth picture with no chance of ever having problems like the Screen Door effect.

LCD chips cannot avoid the controlling transistor circuitry coming in the way of the light path, because the light has to pass through each LCD pixel in an LCD Chip. So there are minute spaces between each pixel for the control circuitry and this is the cause of the screen door effect in LCD projectors.
