Abstract
Devices, arrangements, and techniques are provided to improve the color saturation of displays such as OLED displays while avoiding or substantially reducing any increase in power consumption that typically would be associated with such increase in saturation. A three-subpixel per pixel red/green/blue (RGB) architecture is provided as well as a four sub-pixel approach which uses two red sub-pixels for each pixel (red/red/green/blue, or R1R2GB).
Claims12
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);
- and
- a green sub-pixel having 1931 CIE coordinates (Gx, Gy);
- wherein the product (0.75−Rx)(Ry−0.25)(Gy−0.5)(0.4−Gx) is at least 1.5.
