  • Publication number: 20240081135
    Abstract: A direct patterning deposition mask for OLED deposition is provided where the mask includes a sapphire substrate; and a Silicon Nitride (SiN) membrane. The sapphire substrate thickness may be between 0.7 and 2 mm. The sapphire substrate may have a diameter in the range of 200 mm diameter to 300 mm diameter. Warpage of the substrate is preferably less than <10 um.

  • Publication number: 20240081136
    Abstract: Systems and methods for performing direct patterning of a material on a substrate with high fidelity to a desired pattern are presented. A pattern of apertures of a shadow mask is compensated to accommodate a range of propagation angles in a vapor plume used to deposit material onto the substrate through the shadow mask. A shadow mask in accordance with the present disclosure includes an aperture pattern in which aperture position is shifted inward toward the center of the shadow mask by an amount based on the distance of the aperture from the center of the shadow mask. As a result, vaporized material passing through an aperture at a non-normal angle deposits onto the substrate at its proper desired location.

  • Patent number: 10091283
    Abstract: A distributed scheduling system is provided for scheduling tasks of providing content items in a digital magazine and verifying completion of tasks performed in a dynamic and scalable way. The distributed scheduling system includes multiple execution devices for executing tasks for generating and presenting the digital magazine, and multiple task service devices for verifying completion of tasks performed by the execution devices. Each of the execution devices and task service devices generates a heartbeat indicating the operation status of the device for executing a corresponding task. A heartbeat is an electric representation generated by the device to indicate the operation status of the device (e.g., operable/functional or inoperable/down). Each task may be associated with a corresponding one of the task service devices, and each task service device may verify completion of its associated tasks.
