摘要： A full-color display and techniques for fabrication thereof are provided. The display includes first and second continuous independently addressable organic emissive layers disposed over a single substrate or between two substrates or portions of a flexible substrate. The use of continuous emissive layers of a limited number of colors allows for a relatively high resolution display to be achieved without the use of fine metal masks or similar components.

摘要： Full-color pixel arrangements for use in displays and other devices, and devices including the same, are provided. The pixel arrangement includes a patterned electrode layer including multiple electrodes, a patterned emissive layer disposed over the electrode layer, a blanket organic emissive layer disposed over the patterned emissive layer, a second electrode layer disposed between the organic emissive layers, and a third electrode layer disposed over the second blanket organic emissive layer. Electrodes within each of the electrode layers are individually addressable.

摘要： 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.

摘要： 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.

摘要： An organic light emitting diode (OLED) architecture in which efficient operation is achieved without requiring a blocking layer by locating the recombination zone close to the hole transport side of the emissive layer. Aryl-based hosts and Ir-based dopants with suitable concentrations result in an efficient phosphorescent OLED structure. Previously, blocking layer utilization in phosphorescent OLED architectures was considered essential to avoid exciton and hole leakage from the emissive layer, and thus keep the recombination zone inside the emissive layer to provide high device efficiency and a pure emission spectrum.
