Thanks for the info. I'm really surprised at that, given that IBM had indicated that the 2k chip was just an exploratory effort, and that seemed too be confirmed in all the publicity releases and photos I saw. Plus there was this article: -JimA IBM JAPAN PRODUCES LCD PROJECTOR ENGINES November 12, 1997 (TOKYO) -- IBM Japan Ltd. started producing microchip-based engines for two types of liquid crystal display (LCD)projectors. The engines are for the UXGA standard (or 1600 x 1280 pixels) and the SXGA standard (or 1280 x 1024 pixels). IBM Japan will sell the engines to projector producers, and the price is not yet set. However, IBM Japan said that such engines typically account for a third of the cost of an entire projector, because the engine is a key component. IBM Japan's engine comprises a small silicon chip-based LCD light-valve and an optical system. It developed the system in collaboration with Nikon Corp. The silicon chip-based LCD is a new projection device featuring semiconductor and LCD technologies. The company has displayed test versions of a UXGA rear-type projector and an SXGA front-type projector. The luminance of the engine is 600ANSI lumen when using a 250W metal-halide lamp. Its ANSI contrast ratio is 100:1. The 1.3-inch silicon chip-based LCD light-valve for the UXGA projector has a pixel pitch of 15.5 micron, and its aperture ratio is 90 percent. For the SXGA projector, the 1.3-inch silicon chip-based LCD light-valve has a pixel pitch of 20 micron, and its aperture ratio is 92 percent. The silicon microchips are produced using the 0.8-micron rule process. Advanced Peripherals Technologies Inc., a joint venture of IBM Japan and TEC Corp. specializing in PC peripherals, plans to commercialize an LCD projector featuring this projection engine in late November. The company will sell the projector for 2.48 million yen (US$20,000). Electrohome Ltd. of Canada plans to introduce a similar projector in December.
