摘要： Devices, arrangements, and techniques are provided to improve the color saturation of displays such as OLED displays while avoiding or substantially reducing any increase in power consumption that typically would be associated with such increase in saturation. A three-subpixel per pixel red/green/blue (RGB) architecture is provided as well as a four sub-pixel approach which uses two red sub-pixels for each pixel (red/red/green/blue, or R1R2GB).

摘要： A hybrid pixel arrangement for a full-color display is provided, which includes an inorganic LED in at least one sub-pixel, and an organic emissive stack in at least one other sub-pixel. In an embodiment, a first sub-pixel is configured to emit a first color, and includes an inorganic LED, a second sub-pixel is configured to emit a second color, and includes a first organic emissive stack configured to emit an initial color different from the first color. A third sub-pixel is configured to emit a third color different from the initial color.

摘要： Embodiments of the disclosed subject matter provide a device having a reflective electrode, and a first organic light emitting device (OLED), where the reflective electrode may be disposed over the first OLED. The device may include a partially reflective electrode, where the first OLED may be disposed over the partially reflective electrode. The device may include a second OLED, where the partially reflective electrode may be disposed over the second OLED. The device may include a first transparent electrode, where the second OLED may be disposed over the transparent electrode, and a substrate, where the transparent electrode may be disposed over the substrate. At least one of the partially reflective electrode and the first transparent electrode may be configured to be independently addressable, and the first OLED may be configured to be separately driven from the second OLED.
