摘要： A method for transforming three color-input signals (R, G, B) corresponding to three gamut-defining color primaries of a display to four color-output signals (R′, G′, B′, W) corresponding to the gamut-defining color primaries and one additional primary of the display, where the additional primary has color that varies with drive level, comprising: a) determining a relationship between drive level of the additional primary and intensities of the three gamut-defining primaries which together produce equivalent color over a range of drive levels for the additional primary; and b) employing the three color-input signals R, G, B and the relationship defined in a) to determine a value for W of the four color-output signals, and modification values to be applied to one or more of the R, G, B components of the three color-input signals to form the R′, G′, B′ values of the four color-output signals.

摘要： A method for controlling and compensating aging in an LED device includes measuring a performance change in light output of the LED device. The LED device is controlled with a first compensation algorithm derived from the measured performance change, during a first period, to effect a luminance change over time in the light output of the LED device. Subsequently, a second compensation algorithm, derived from the measured performance change, and different from the first compensation algorithm, during a second period, effects a second luminance change over time in the LED device's light output. The second luminance change over time in the second period is different from the first luminance change over time in the first period. Furthermore, the first and second periods together are less than the lifetime of the LED device.
