Philips 56in. Quad Full HD LCD

Philips 56in. Quad Full HD LCD

Starting at the end of last year, Philips has been offering its 56in. glasses-free 3D display based on a 3840×2160 resolution LCD panel. Using its own WOWvx technology, the Philips 56in. Quad Full HD (QFHD) autostereoscopic LCD display creates 46 lenticular viewing zones, which provides one of the best 3D experiences without polarized or flicker lenses. If you want to really knock people's eyes for a loop, consider Philips' new 132in. 3D WOWzone videowall approach. The 132in. 3D WOWzone combines nine of Philips' earlier 42in. WOWvx 3D multiview autostereoscopic lenticular displays into an attention-grabbing multiscreen messaging tool that is designed for large indoor spaces and comes on a wheel-based frame for mobile installation. The central enabling technology for all of this is the flexible WOWvx 2D-plus-Depth format, which allows decoupling of content creation and content visualization. Philips' autostereoscopic 3D displays support the unique Declipse image format, which enables a true look-around effect along with the 3D visualization.

Built with a unique StereoMirror design, Planar System's SD2620W delivers full-resolution widescreen WUXGA (1920×1200) images to both eyes for superior stereo imaging with passive, polarizing glasses. In the StereoMirror design, this bioptic separation is achieved using the principle of conservation of polarization. Unlike other technologies, Planar claims that with its SD2620W, multiple users can be sitting or standing and see the same quality image because there is no sweet spot anywhere on the screen. In Planar's SD line of monitors (where “SD” stands for “stereo display,” not “standard definition”), the planes of polarization for light emitted from the two AMLCDs in a StereoMirror have the same orientation — for example, 45 degrees. As a result, the plane of polarization for the left-eye image seen in transmission from the lower monitor is unchanged in passing through the mirror. However, the polarization plane in the light path of the upper monitor (right-eye image) is effectively rotated 90 degrees upon reflection. Images with orthogonal polarization are extinguished, and the result is a single, fused stereoscopic image.

Samsung 2233RZ

Samsung 2233RZ

In January, Samsung announced its first professional 3D monitor; the 22in. 2233RZ. Samsung has long been known for its best-of-class consumer 3D displays, but its new 2233RZ is geared for professional applications because it is compatible with Nvidia's GeForce 3D Vision graphics card. With environmental concerns in mind, Samsung built an off-timer function into the display for energy-saving benefits, enabling the monitor to shut down at preset times. Unlike other widescreen monitors, the 1680×1050-resolution 2233RZ displays 5:4 and 4:3 images at accurate aspect ratios without enlargement or distortion. The display also monitor boasts a refined, streamlined, unique design. It will be available for purchase in April 2009.

If you want the highest-resolution digital 3D display available for corporate installation, Sony has released a 3D adapter designed to work specifically with its 4K projectors. The new single-projector-lens units, models LKRL-A002 (X1.1-1.9) and LKRL-A003 (X1.9-3.3), consist of an optical and mechanical assembly for each left-eye and right-eye image. Because the source projector puts out a total of 4K resolution, this means each eye is seeing 2K images. When used with Sony's integrated media block (LMT-200), the SRX-R220 4K projector is able to achieve 4:4:4 RGB signal path from the media block while avoiding the triple-flash artifacting claimed to plague some current 3D solutions. The 3D adapter attaches to the lens mount of the projector and is compatible with all Sony 4K projectors in the field.
