Colours that are Sharp
07 December 2010
New five-primary-colour LCD ensures faithful colour reproduction.
Sharp has prototyped a five-primary-colour display that faithfully reproduces the real surface colours that the human eye is capable of perceiving.
The pixel structure of the new type of panel is based on five-colours, adding the colours C (cyan) and Y (yellow) to the three standard R (red), G (green), and B (blue) colour set. This combination expands the colour gamut that can be rendered within the colour spectrum that humans can discern with the unaided eye, and enables the new display type to reproduce more than 99% of real surface colours.
Nearly all real surface colours can be rendered faithfully, even those like the colour of the sea (emerald blue), brass instruments (golden yellow), and roses (crimson red), which have been difficult to render using conventional RGB colour schemes. For example, with a standard sRGB scheme for computer and monitor display devices, only 35% to 60% of all real surface colours can be reproduced.
The newly developed display type from Sharp with RGBCY colour scheme also comprises ‘Multi-Primary-Colour Technology’ that features special image processing circuitry.
As adoption of this technology will enable more efficient use of light energy produced by the backlight, this display technology will also provide greater energy savings.
In the future, Sharp will be working to further improve the basic performance of this display and making efforts toward its practical application. The company has not yet announced when the new five-primary-colour scheme will be seen in its products.
