Abstract: Devices and techniques are provided in which an OLED panel is operated in two modes. The first mode operates in a standard way to display an image or video or otherwise illuminate sub-pixels of the panel. In the second mode, some pixels are operated at a lower brightness than in the first mode. The use of multiple modes allows for improved sub-pixel lifetime and reduced sub-pixel and image degradation.

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.
