Abstract: Embodiments of the disclosed subject matter provide a device that may include an emissive surface having a plurality of pixels. Each pixel of the plurality of pixels may have three or more sub-pixels. At least one sub-pixel of the three or more sub-pixels may be disposed over at least one other sub-pixel of the three or more sub-pixels. Each pixel of the plurality of pixels may be configured to render a color gamut of at least 85% of a color space.

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).

Abstract: Embodiments of the disclosed subject matter provide a device having a full-color organic light emitting device (OLED) display having a plurality of pixels, with each pixel having a plurality of sub-pixels and where no individual sub-pixel of the plurality of sub-pixels emits white light. The OLED display may be configured to operate with a luminance of at least 1,000 cd/m2 at the D65 or higher white point, and using not more than a 0.5 mA/cm2 drive current for a blue sub-pixel of the plurality of sub-pixels based on an overall active area of the full-color OLED display.

Abstract: A hybrid pixel arrangement for a full-color display is provided, which includes an inorganic LED in at least one sub-pixel, and an organic emissive stack in at least one other sub-pixel. In an embodiment, a first sub-pixel is configured to emit a first color, and includes an inorganic LED, a second sub-pixel is configured to emit a second color, and includes a first organic emissive stack configured to emit an initial color different from the first color. A third sub-pixel is configured to emit a third color different from the initial color.

Abstract: Embodiments of the disclosed subject matter provide a device having an organic light emitting device (OLED) display comprising a plurality of metapixels. Each metapixel of the plurality of metapixels may have two or more sets of emissive regions that are configured to: (i) emit blue light that is a combination of light from the two or more sets of emissive regions that are configured to emit the blue light for that metapixel, and/or (ii) that are addressable by the same drive circuit. The metapixel may include more than one independently addressable sub-pixel configured to emit green light and more than one independently addressable sub-pixel configured to emit red light.
