Abstract: Embodiments of the disclosed subject matter provide a device including an organic light emitting device (OLED) display having at least one pixel having a plurality of sub-pixels, where at least one color sub-pixel of the plurality of sub-pixels may be configured to output red light, green light, and/or blue light. The device may include at least one sub-pixel that is configured to have a Lambertian emission, and at least one sub-pixel having a microcavity configured for direct emission such that a first ratio of light from the direct emission sub-pixel in a cone having an angle of 0-20° in a normal direction relative to an overall light emission from the direct emission sub-pixel having at least 10%, at least 20%, and/or at least 30% higher than a second ratio of light from the Lambertian emission sub-pixel.

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.
