Sony develops high-contrast HD display technology

Sony Electronics has developed a new technology that delivers full high-definition resolution (1920 x 1080) on a display panel with a contrast ratio of more than 3000 to one. Called Silicon Crystal [X-tal] Reflective Display (SXRD), the new monitoring technology provides smooth, film-like picture quality unavailable in previous fixed pixel displays.

The picture quality is generated by an SXRD technology. SXRD has high picture density — with more than two million pixels contained in each image area. By reducing both the size of each individual pixel, as well as the space between the pixels, SXRD more than doubles the pixel density and achieves a 10-fold inter-pixel spacing in comparison to high temperature Poly-Silicon liquid crystal display (H-LCD) devices.

An SXRD display device with the smallest inter-pixel spacing enables full HD (1920 x 1080, 16:9 widescreen aspect ratio) resolution within an image area measuring only 0.78-inches diagonally. In addition, each SXRD liquid crystal cell gap measures less than two micrometers—far thinner than conventional H-LCD or Liquid Crystal on Silicon (LCoS) devices.

SXRD technology will be introduced in new HD monitoring products later this year. Its features and capabilities allow for possible future use in both front projectors and rear projection television devices.
