  • Patent number: 10839734
    Abstract: Techniques, devices, and systems are provided that allow for driving a device such as an OLED in various pulsed modes in which a momentary luminance greater than an apparent luminance at which the OLED is to be driven is used. The use of one or more pulsed modes allows for the lifetime of the OLED to be extended and reduces image sticking. Pulsed modes are also provided that allow for color tuning of the device by activating different portions of one or more emissive areas of the device.

  • Publication number: 20200357860
    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.

  • Patent number: 10700134
    Abstract: This disclosure relates to reduced power consumption OLED displays at reduced cost for reduced information content applications, such as wearable displays. Image quality for wearable displays can be different than for high information content smart phone displays and TVs, where the wearable display has an architecture that in includes, for example, an all phosphorescent device and/or material system that may be fabricated at reduced cost. The reduced power consumption can facilitate wireless and solar charging.

  • Publication number: 20200176701
    Abstract: 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.

  • Patent number: 10586486
    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.

  • Publication number: 20200027931
    Abstract: Embodiments of the disclosed subject matter provide a wearable device that includes an organic light emitting diode (OLED) light source to output light having one peak wavelength from a single OLED emissive layer, and a first barrier layer that is disposed over or between the single OLED emissive layer and one or more down-conversion layers. One or more regions of the single OLED emissive layer are independently switchable and controllable so that the wearable device is configurable to output a plurality of wavelengths of light. One of the plurality of wavelengths of light that is output is near infrared light.
