US 2017/0287988 A1 · ORGANIC LIGHT EMITTING DISPLAY DEVICE

Abstract

Provided is an organic light emitting display device including a plurality of sub pixels. Areas of emission regions of green sub pixels of the plurality of sub pixels are the same as or larger than an area of an emission region of at least one non-green sub pixel of the plurality of sub pixels. Also the organic light emitting display device includes an area of an emission region of a green sub pixel having a low luminance lifetime being the same as or larger than areas of emission regions of non-green sub pixels. Accordingly, it is possible to make the luminance lifetime of the green sub pixel and the luminance lifetimes of the non-green sub pixels uniform. Further, it is possible to minimize a color change of the organic light emitting display device.

Dependent claims

An organic light emitting display device, comprising:

a plurality of sub pixels,
wherein areas of emission regions of green sub pixels of the plurality of sub pixels are the same as or larger than an area of an emission region of at least one non-green sub pixel of the plurality of sub pixels.

An organic light emitting display device, comprising:

a plurality of sub pixels,
wherein areas of emission regions of each of the plurality of sub pixels are adjusted based on a luminance lifetime per unit area of each of the plurality of sub pixels, and
wherein the luminance lifetime per unit area of the each of the plurality of sub pixels is a time to be taken until a luminance of each of the plurality of sub pixels reaches 95% of an initial luminance thereof, wherein a rate of variation in the luminance lifetime per unit area of the plurality of sub pixels is within 1%.

Dependencies are inferred from the claim text.
