1. A device comprising:
a full-color organic display panel comprising a plurality of pixels, at least one of the plurality of pixels comprising:
a red sub-pixel having 1931 CIE coordinates (Rx, Ry);
a green sub-pixel having 1931 CIE coordinates (Gx, Gy); and
a blue sub-pixel;
wherein the product
(0.75−Rx)(Ry−0.25)(Gy−0.5)(0.4−Gx)(104)
is at least 1.50; and
wherein the color gamut enabled by the RGB colors emitted by the at least one pixel is at least equal to 100% of the area of the DCI-P3 color gamut based on 1931 CIE coordinates.
