Abstract: 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.

Abstract: Embodiments of the disclosed subject matter provide a full-color pixel arrangement for a device, the full-color pixel arrangement including a plurality of sub-pixels, each having an emissive region of a first color, where the full-color pixel arrangement comprises emissive regions having exactly one emissive color that is a red-shifted color of a deep blue sub-pixel of the plurality of sub-pixels. Embodiments of the disclosed subject matter may also provide a full-color pixel arrangement for a device, the full-color pixel arrangement including a plurality of sub-pixels, each having an emissive region of a first color, where the full-color pixel arrangement comprises emissive regions having exactly one emissive color, and where the plurality of sub-pixels comprise a light blue sub-pixel, a deep blue sub-pixel, a red sub-pixel, and a green sub-pixel.

Abstract: Light emitting devices including sub-pixels having different numbers of emissive layers are provided. At least one sub-pixel of a first color may include a single emissive layer, and at least one sub-pixel of a second color may include multiple emissive layers disposed in a vertical stack. Light emitting devices in which different voltages are applied to each sub-pixel or group of sub-pixels are also provided. In some configurations, the voltage to be applied to a sub-pixel may be selected based upon the number of emissive layers in the sub-pixel.

Abstract: OLEDs containing a stacked hybrid architecture including a phosphorescent organic emissive unit and two fluorescent organic emissive units are disclosed. The stacked hybrid architecture includes a plurality of electrodes and a hybrid emissive stacked disposed between at least two of the electrodes. The stack contains at least three emissive units and at least two charge generation layers. At least one of the three emissive units is a phosphorescent organic emissive unit and at least two of the three emissive units are fluorescent organic emissive units. More specifically, the two fluorescent organic emissive units may be blue organic emissive units that emit light from the same or different color regions.

Abstract: Methods of operation and devices are provided in which the operation of a full-color display is modified based upon historical luminance data that indicates an intensity at which at least one sub-pixel of the device is driven over a period of time. An expected degradation level of one or more pixel elements in the device is calculated based upon the luminance data, and video signals received by the device are modified based upon the expected degradation level to reduce image sticking and/or other undesirable effects in the device.
Abstract translation: 提供了操作方法和装置，其中基于指示在一段时间内驱动装置的至少一个子像素的强度的历史亮度数据来修改全色显示器的操作。 基于亮度数据计算设备中的一个或多个像素元素的期望的劣化水平，并且基于预期的劣化水平修改由设备接收的视频信号，以减少设备中的图像残留和/或其他不期望的影响。

Abstract: Embodiments of the disclosed subject matter provide a device having a substrate, at least one organic light-emitting layer disposed over the substrate, and at least one down-conversion layer. The at least one down-conversion layer may generate the NIR emission by absorbing at least a portion of the light emitted by the at least one organic light emitting layer, and re-emitting light at a longer NIR wavelength or range of wavelengths having a peak NIR emission that may be greater than 700 nm, greater than 750 nm, or greater than 800 nm. An out-of-plane optical density of the at least one down-conversion layer may be less than 0.1 for all wavelengths of light in a range from 400 nm to 600 nm.
