NOVEL OLED DISPLAY ARCHITECTURE

摘要

A device that may be used as a multi-color pixel is provided. The device has a first organic light emitting device, a second organic light emitting device, a third organic light emitting device, and a fourth organic light emitting device. The device may be a pixel of a display having four sub-pixels. The first device may emit red light, the second device may emit green light, the third device may emit light blue light and the fourth device may emit deep blue light. The device includes a first device plane and a second device plane. The first device plane comprises a plurality of the first organic light emitting device and a plurality of the second organic light emitting device. The second device plane comprises a plurality of at least one of the third organic light emitting device and the fourth organic light emitting device. The planes of the first and second device planes are parallel. The second device plane is transposed from the first device plane in a direction perpendicular to the planes of the first and second device planes. The first and second device planes are superposed.
