Intel divulges digital silicon plans for HDTVs

Intel President and COO Paul Otellini presented details on the latest Intel silicon technology that is expected to bring about high-definition, large-screen TVs with clearer pictures than current systems for less than $2,000.

The new Intel technology, code-named Cayley, is based on a technique called Liquid Crystal on Silicon (LCOS), which is used to create small chips called microdisplays that produce images that are displayed on large-screen, rear projection TVs.

LCOS technology sandwiches a layer of liquid crystal between a cover glass and a highly reflective, mirror-like surface patterned with pixels that sits on top of a silicon chip. These layers form a microdisplay that can be used in projection displays such as large-screen, rear-projection TVs. Intel's Cayley LCOS technology uses Intel's advanced silicon manufacturing processes to produce a high-quality surface for reflecting light which creates an extremely bright display.

Another key aspect of the LCOS technology is that it enables the creation of multiple microdisplays with increasing levels of resolution without changing size of the microdisplay. The consistent and compatible display area of microdisplays based on Intel's LCOS technology will enable OEMs to reuse light engine designs for a wide array of products in various screen sizes and resolutions, thus reducing their development costs.

Intel plans to deliver microdisplays based on Cayley in the second half of this year. A number of leading OEMs and HDTV component manufacturers, including InFocus Corp. of the U.S., TCL and Skyworth of mainland China and Primax PDC of Taiwan are currently developing products based on prototype microdisplays from Intel.
