Organic electroluminescent devices

A device comprising:

• an organic light emitting device (OLED) display comprising at least one pixel having a plurality of sub-pixels,
• wherein at least one color sub-pixel of the plurality of sub-pixels is configured to output red light,
• wherein at least one color sub-pixel of the plurality of sub-pixels is configured to output green light,
• wherein at least one color sub-pixel of the plurality of sub-pixels is configured to output blue light,
• wherein at least two of the group consisting of:
• the at least one color sub-pixel configured to output red light, the at least one color sub-pixel configured to output green light, and the at least one color sub-pixel configured to output blue light have 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 is selected from the group consisting of:
• at least 10%, at least 20%, at least 30% higher than a second ratio of light from the Lambertian emission sub-pixel in a cone having an angle of 0-20° in a normal direction relative to an overall light emission from the Lambertian sub-pixel, and
• wherein the at least one sub-pixel that has the Lambertian emission and the at least one sub-pixel having the microcavity configured for direct emission have the same emitters with the same chemical composition.
