Intel delays LCOS chip

US chip-maker Intel has postponed release of its high-definition television (HDTV) display technology, intended as a cheaper alternative to those made by rivals such as Texas Instruments (TI), because its liquid crystal on silicon (LCOS) system needs refining.

Intel unveiled its research and development effort into LCOS last January at the US Consumer Electronics Show, and demonstrated its capabilities at the Intel Developer Forum a month later - but the chips now look unlikely to be available in the second half of this year as originally intended.

The system works by placing thousands of tiny liquid crystal display (LCD) cells on a silicon wafer, so that light hitting the surface is reflected - or not, as the case may be - according to the state of each cell. Then the light is magnified and projected on a screen.

In contrast, Texas Instruments' Digital Light Processing (DLP) system uses computer-controlled mirrors to reflect the light and is expensive to produce. Intel said it is holding back the LCOS chip to make improvements.
