Israel-based Genoa Color Technologies has taken the television color gamut, traditionally consisting of red, green, and blue (RGB), and expanded it to reflect a wider range of colors without compromising brightness.

Genoa Color Technologies’ Keshet chip is placed after a television’s standard interface and before the display controller in order to broaden the color gamut from traditional TV (Top Figure) to simulate the color gamut of film (Bottom Figure). The non-linear conversion is mapped from incoming color space to a larger color space on the display and is said to provide richer, brighter colors.

Genoa’s product, the Keshet™ family of multi-primary conversion ICs, when combined with electro-optical changes in the display, reportedly expand the coverage of the visible color gamut from 55 to 95 percent, allowing color televisions to fully display a spectrum of colors. The end result is said to simulate the look of film media.

According to Simon Lewis, vice president of Marketing & Business Development, the selection of color is a function of the display’s color gamut, brightness level, and the achievement of a balanced white, in addition to the technology being employed (CRT, LCD, etc.). “In LCD TVs, color comes from dividing each white pixel into smaller sub-pixels, one per primary,” he explains. “To make a multi-primary LCD panel, you need to subdivide the white pixel into a larger number of smaller sub-pixels.”

The Keshet chip relies on transformation algorithms that enable the conversion of video inputs into a multi-primary display domain. By placing the chip after the standard interface and before the display controller, the standard RGB signal is translated by a non-linear conversion to display four to six primary colors.

In addition, the technology is said to not compromise the brightness level of the display when expanding the level of color, as it does traditionally. “A TV with a standard color gamut would have a brightness index of 1,” Mr. Lewis tells APPLIANCE. “Extending this gamut toward the gamut of film would usually result in the a loss of around 50-percent of the brightness.” Genoa, he says, has moved the curve upwards so that a TV can retain a brightness level of 1 and still offer the full gamut of film. Now, instead of delivering a lower brightness level for a higher level of color, both can be delivered without the expense of each other.
