Sharp developed a LCD based on five primary colours which can display colours in nature just as we see with our eyes.

Colours that couldn't be reproduced on existing LCDs such as the colour of the sea (emerald blue), brass instruments (golden yellow) and roses (crimson red) can be rendered faithfully. Plus, the new display is energy-saving as well.

Read on for details.


Sharp Develops Five-Primary-Color LCD That Faithfully Reproduces Real Surface Colors | Press Releases:SHARP

According to this press release, Sharp started this project prompted by the growing demands of displays that can render colours of objects true to what they appear in flesh to the human eye, in fields such as industrial design, digital archiving, network-based remote medical care, and electronic commerce.

The display can render more than 99% of surface colour existing in the real world. They achieved this by "Multi-Primary-Color Technology" which features display panel based on five-colour filters that add C (cyan) and Y (yellow) to the usual RGB (Red, Green, Blue), with special image processing circuitry.

In addition to the faithful rendition of real surface colours, the technology also provide greater energy saving by efficient use of light energy produced by the backlight.

A prototype of this "Multi-Primary-Colour Display" will be exhibited at the international symposium of the Society for Information Display (SID) to be held in San Antonio, Texas, US from May 31 through June 5, 2009.

The prototype is in 60.5 inch Full-HighVision (1920*1080), with 450cd/m2 brightness, contrast ratio of 2000: 1, 6500K colour temperature and of course, the colour reproducibility of "Dreater than 99% of surface colour gamut".

"Sharp will be working to further improve the basic performance of this display and making efforts toward its practical application", they say.
