Sharp Five-Color LCD over 99% of visible colors

Sharp have apparently developed a new five-color LCD that’s capable of displaying more than 99-percent of real surface colors.  That means that the display is able to show almost all of the colors the unaided human eye can see, including hitherto tricky or impossible shades such as the color of the sea (emerald blue), brass instruments (golden yellow), and roses (crimson red).

The new panel adds cyan and yellow to the traditional red, green and blue color filters, requiring a new pixel structure, together with introducing new image processing circuitry.  As well as offering broader support of the color gamut, the new technology also allows for more efficient backlighting, meaning the Sharp displays actually require less energy than a traditional three-color LCD.

The prototype panel, on show at the SID symposium in Texas from the end of May, measures 60.5-inches and runs at 1,920 x 1,080 high-definition resolution.  It has a contrast ratio of 2,000:1 and 450 cd/m2 brightness.  Sharp expect the technology to find a place in remote medical care, digital archiving and industrial design.  They’re yet to release photos of the panel.
