High-Dynamic-Range Display
This high-dynamic-range (HDR) display uses active light-emitting diodes behind a high-resolution color liquid-crystal display and offers 4,000 Nits (or cd/m2) to 0.05 Nits (or cd/m2) luminance range at video rate with an extended color gamut and 16-bit depth per color.

Life Enhancement
This HDR display achieves unrivaled brightness, contrast, and color accuracy, which are required in many applications: film editing, medical imaging, satellite imagery, etc.

Vision
This system offers a competitive solution with 300 times higher contrast, 10-30 times higher brightness, 10-30 times lower "darkness," and 38 percent better coverage of the NTSC color gamut due to the use of RGB LED. It is a very strong challenge to conventional display technology. We believe that the HDR display can become the TV display solution of the future.

Goals
Development of a commercially competitive display system that can show images that are visually indistinguishable from the outside world (at the right viewing distance).

Innovations
Combination of a locally dynamic backlight and LCD

Low-resolution backlight with compensation in high-resolution LCD

Psycho-physics theory to support compensation

Real-time driver software

Various applications for HDR displays (volume renderers, image browsers, editing tools, etc.)
