Sharp new five-primary-color LCD for faithful color reproduction
Adding two colors to the standard RGB LCD color scheme Sharp achieves improved color reproducibility of LCDs rendering 99 percent of all real surface colors.
Hamburg 24 September 2009 – Sharp has prototyped a five-primary-color display that faithfully reproduces the real surface colors that humans are capable of perceiving. The pixel structure of the new type of panel is based on five-colors adding the colors C (cyan) and Y (yellow) to the three standard R (red), G (green), and B (blue) color set. This combination expands the color gamut that can be rendered within the color spectrum that humans can discern with the unaided eye, and enables the new display type to reproduce more than 99 percent of real surface colors. Nearly all real surface colors can be rendered faithfully, even those like the color of the sea (emerald blue), brass instruments (golden yellow), and roses (crimson red), that have been difficult to render using conventional RGB color scheme. For example: with a standard sRGB scheme for computer and monitor display devices only 35 to 60 percent of all real surface colors can be reproduced. The newly developed display type from Sharp with RGBCY color scheme also comprises “Multi-Primary-Color 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. At first prototype has been on display at the SID conference in the US this summer. However, when the new five-primary-color scheme will be seen in the first products is not yet determined.
