Abstract: The present invention relates to OLED devices and stacks for OLED devices that include a symmetric emissive-layer architecture. In one embodiment, the present invention relates to an emissive stack having three layers, wherein the top and bottom layers emit light in the same or similar color region while the middle layer emits light in a different color region than the other two layers. In such an embodiment, the three layers are in contact with each other with no other layers in between. The symmetric emissive-layer architecture of the present invention can be used to improve the color stability of OLED devices.

Abstract: Organic light emitting devices (OLEDs) are provided that include two red emissive dopants. The two dopants may be disposed within a common organic emissive layer in an OLED, or each may be disposed in a separate layer. Configurations including multiple layers having multiple dopants are also provided, in which a first red dopant is disposed in a separate organic layer from a second red dopant, and a common dopant of another color, such as green, is disposed in each organic layer. Devices as disclosed herein are capable of providing an R9 value of at least 80, and of providing white light with a CRI of at least 80.

Abstract: Embodiments of the disclosed subject matter provide a device having a substrate, and a plurality of unit areas of an organic light emitting diode (OLED) display disposed on the substrate. The unit areas may be repeating, area-filling subdivisions of the substrate that each have an anode and a cathode. The organic film may be disposed over portions of the device other than the unit areas. The device may include at least one pixel having a plurality of sub-pixels disposed within each of the plurality of unit areas. The cathode of at least one pixel of each of the plurality of unit areas may be a common cathode.

Abstract: Arrangements of pixel components that allow for full-color devices, while using emissive devices that use blue color altering layers in conjunction with blue emissive regions, that emit at not more than two colors, and/or that use limited number of color altering layers, are provided. Devices disclosed herein also may be achieved using simplified fabrication techniques compared to conventional side-by-side arrangements, because fewer masking steps may be required.

Abstract: Arrangements of pixel components that allow driving three or less of four or more sub-pixels to emit an original color signal are disclosed. A first projection of the original color signal may be projected onto the two sub-pixel's color space. The first projection may then be projected onto a second projection corresponding to the color space of a third pixel. The third pixel may be driven based on the second projection only two of the remaining at least three sub-pixels may be driven based on the third pixel being driven.
