    • Methods for displaying an image on a color display having a target display white point luminance and chromaticity, and including three gamut-defining emitters defining a display gamut and two or more additional emitters which emit light within the display gamut; the method including receiving a three-component input image signal; transforming the three-component input image signal to a five-or-more component drive signal; and providing the drive signal to display an image corresponding to the input image signal. One method provides a reproduced luminance value higher than the sum of the respective luminance values of the three components of the input signal when reproduced with the gamut-defining emitters. Another method provides reduced power in an OLED display including a white-emitting layer with three color filters for gamut-defining emitters and two or more additional color filters for three additional within-gamut emitters.
    • 用于在具有目标显示白点亮度和色度的彩色显示器上显示图像的方法,并且包括限定显示色域的三个色域定义发射器和在显示区域内发光的两个或更多个附加发射器; 所述方法包括接收三分量输入图像信号; 将三分量输入图像信号转换成五分之一或更多分量驱动信号; 以及提供所述驱动信号以显示与所述输入图像信号相对应的图像。 一种方法提供当用色域定义的发射器再现时,高于输入信号的三个分量的各个亮度值之和的再现亮度值。 另一种方法在OLED显示器中提供降低的功率,包括具有用于色域定义发射器的三个滤色器的白色发光层和用于三个额外的色域内发射器的两个或更多个附加滤色器。
