  • OLED color tuning by driving mode variation
    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.

  • NON-BLOCKED PHOSPHORESCENT OLEDS
    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.

    Abstract: The present invention relates to OLED devices and stacks for OLED devices that include a symmetric emissive-layer architecture. In one embodiment, the present invention relates to an emissive stack having three layers, wherein the top and bottom layers emit light in the same or similar color region while the middle layer emits light in a different color region than the other two layers. In such an embodiment, the three layers are in contact with each other with no other layers in between. The symmetric emissive-layer architecture of the present invention can be used to improve the color stability of OLED devices.
