1. A display system having a first operational mode for high circadian stimulation (CS), and a second operational mode for low CS, said display comprising:
an array of pixels, each pixel comprising emissive subpixels, said emissive subpixels comprising a green subpixel, a high CS-blue subpixel, a low-CS-blue subpixel, and a green subpixel, said high CS-blue subpixel emitting a light having a peak wavelength greater than 470 nm and no greater than 510 nm, said low CS-blue subpixel emitting light having wavelength between about 400 nm and about 430 nm; and
a controller for controlling said pixels in at least said first and second operational modes, wherein in said first operational mode, said red subpixel, said high CS-blue subpixel, and said green subpixel are powered, and, in said second operational mode, said red subpixel, said low-CS-blue subpixel, and said green subpixel are powered.
