At 21 millimeters measured diagonally, the E-HD LCOS imaging chip from MicroDisplay Corp. is a single-panel 1920x1080 LCOS microdisplay with a resolution of two million pixels. Aimed at the 40-inch and larger rear projection television market, the LCOS display chipset comes complete with a single chip controller IC and a full programming graphical user interface for fast evaluation and design. A custom designed color wheel ensures color convergence and increases the brightness of the image. The E-HD shows 1080 progressive lines on the screen, improving on the more common 720 lines of progressive scan in current HDTV systems. The E-HD reduces the cost of using LCOS by needing a single panel as opposed to the more common three-panel solutions. www.microdisplay.com.

Rockwell Collins' (Cedar Rapids, IA) SIM EYE SR100 display system is designed to mount to either the pilot's own helmet or the company's ProView headband. It features full color SXGA resolution, a 100 x 50 x 115 degree field of view and a lightweight display and optical module. It also features an advanced "Clip and Go" concept, allowing the aviator to mount the system to his flight helmet. This added versatility and ease of use provides more comfort and efficiency, yielding a more effective training experience, the company says. www.rockwellcollins.com.

Samsung Electronics (Seoul, Korea) has developed a 4-inch screen digital interface LCD with a 16:9 screen ratio exclusively for Portable Media Players (PMPs), which are next-generation multimedia players that can play video images downloaded from the Internet. Samsung's 4-inch widescreen LCD features a 16:9 ratio, compared to a 4:3 ratio found in a PMP's 3.5-inch panels. In addition, its 8-bit digital interface allows for 16.7 million color video images, and its 50 percent color gamut offers a clear and crisp image display. PMPs are used outdoors, and so the brightness has been enhanced from 150 nits, the general brightness of mobile handsets, to 180 nits. Moreover, visibility is enhanced through TMR (Transmissive with Micro Reflective) mode, which reduces the reflection of sunlight. www.samsung.com.

Shimadzu Corp. of Japan (Kyoto, Japan) introduces Dataglass 2/A, its latest version of Head-Mounted Displays. Dataglass 2/A, powered by a USB port, allows users to view computer displays and the outside world simultaneously. DG2's SVGA display (VGA mode also available) supports the user with a full-color resolution of 600x800 pixels to decipher the small on-screen details. It connects to the computer's monitor port (analog-RGB/sub-15 connector) with a color resolution of SVGA or VGA. www.shimadzu.com; www.spi-inc.com.

The TFS1216-010 from Three-Five Systems (Tempe, AZ) incorporates a 128x160 TFT primary display and a 96x64 secondary display, which shares a common white LED backlight. The TFS1216-010 model is designed for flip-phone applications, helping cell phone manufacturers to develop thinner, lighter phones. The primary display is a thin-film transistor a-Si display with transmissive display, a 128 RGB (H) x 160 (V) format, 262,000 colors, a contrast ratio of 150:1 and a brightness of 150 nits. The secondary display is a color STN with transflective display, a format of 96 RGB (H) x 64 (V), 4,000 colors, a 12:1 transmissive contrast ratio and a brightness of 30 nits. www.tfsc.com.
