Brillian Announces Its BR1080 HC Gen II Liquid-Crystal-On-Silicon (LCoS) Microdisplay Ideally Suited For High-Performance 1080p Rear-Projection HDTV Applications

1-Sep-04

Brillian Corporation has announced the introduction of their BR1080HC microdisplay. The 0.72 inch diagonal, 1920 x 1200 panel features Brillianís proprietary Gen II liquid-crystal-on-silicon (LCoS) technology, which delivers industry-leading image quality and contrast ratios as high as 2000:1. Brillian recently demonstrated their new microdisplays in a three-panel, 65-inch, 1080p rear-projection HDTV prototype at the Society for Information Display (SID) conference in Seattle, Washington. In addition to the microdisplays, the prototype HDTV leverages a three-panel LCoS light engine, based on the JDS Uniphase LCOS light engine along with Brillian proprietary drive electronics. Each Brillian BR1080HC microdisplay contains more than 2.3 million pixels for rear-projection HDTV applications that demand the highest broadcast resolution available. With a 0.72-inch diagonal array and a mere 8.1 micron square pixel, this panel fulfills the LCOS promise: densely packed pixels in a tiny microdisplay that allows delivery of high-definition content in a slim profile, lightweight TV product.Even with the small pixel and panel size, the aperture ratio (fill factor) is still greater than 90-percent. Its reflectance is greater than 65-percent enabling the engine to deliver over 500 cd/m2 (nits) brightness and outstanding uniformity from edge to edge on the screen. In addition, although the interface to the system is fully digital, the gray scale and color rendition are analog. This ensures that the video performance can be optimized with great precision for the smoothest, highest-quality, artifact-free image. Robert Melcher, chief technology officer, Brillian, said ìWith its outstanding image quality and price/performance, the BR1080HC panel is an ideal component for the development of 1080p high-definition television products. Brillian plans to introduce these components in its own complete HDTV products. The components and/or light engines will also be made available to selected OEMs looking for the highest-performance and highest-quality panel and/or engine solution for their next-generation 1080p products.îBrillianís reflective, active-matrix-driven BR1080HC liquid crystal displays feature more than 2.3 million, 8.1 micron square pixels, each of which is capable of displaying more than 256 gray levels. As a result, HDTVs based on Brillianís technology will feature grayscale detail at all brightness levels, even in the darkest scenes -matching the visual response of the eye. The technology supports a high fill factor (greater than 90-percent) assuring a smooth, artifact-free image. Its three-panel optical architecture, along with fast response time (less than 10 milliseconds) enables exceptional video reproduction without color break-up or digital artifacts. Importantly, the Brillian Gen II LCoS architecture supports the ability to easily scale to ultra-high resolutions to meet the highest-definition broadcast and computing standards. Production of the BR1080HC is scheduled to begin in the fourth quarter of 2004. Complete products will be introduced in the first quarter of 2005.
