  • Patent number: 10784470
    Abstract: An ink printing process employs per-nozzle droplet volume measurement and processing software that plans droplet combinations to reach specific aggregate ink fills per target region, guaranteeing compliance with minimum and maximum ink fills set by specification. In various embodiments, different droplet combinations are produced through different printhead/substrate scan offsets, offsets between printheads, the use of different nozzle drive waveforms, and/or other techniques. These combinations can be based on repeated, rapid droplet measurements that develop understandings for each nozzle of means and spreads for expected droplet volume, velocity and trajectory, with combinations of droplets being planned based on these statistical parameters. Optionally, random fill variation can be introduced so as to mitigate Mura effects in a finished display device. The disclosed techniques have many possible applications.

  • Patent number: 10512931
    Abstract: Apparatus and techniques for use in manufacturing a light emitting device, such as an organic light emitting diode (OLED) device can include using one or more modules having a controlled environment. The controlled environment can be maintained at a pressure at about atmospheric pressure or above atmospheric pressure. The modules can be arranged to provide various processing regions and to facilitate printing or otherwise depositing one or more patterned organic layers of an OLED device, such as an organic encapsulation layer (OEL) of an OLED device. In an example, uniform support for a substrate can be provided at least in part using a gas cushion, such as during one or more of a printing, holding, or curing operation comprising an OEL fabrication process. In another example, uniform support for the substrate can be provided using a distributed vacuum region, such as provided by a porous medium.

  • Patent number: 10380402
    Abstract: A system and method are disclosed for conserving power during navigation, e.g., user device pointer/cursor navigation, using a fingerprint image sensor, that may comprise processing, via a computing device, fingerprint image sensor data indicative of finger position and movement with respect to a fingerprint image sensor surface in a finger navigation mode to determine if the finger is in a first finger navigation mode; processing, via the computing device, fingerprint image sensor data indicative of finger position and movement with respect to a fingerprint image sensor surface in a finger navigation mode to determine if the finger is in a second finger navigation mode; and transitioning, via the computing device, the fingerprint image sensor from a first power consumption mode to a second power consumption mode, based on detecting a transition from the first finger navigation mode to the second finger navigation mode.

  • Patent number: 10137635
    Abstract: Functionally graded materials can be prepared through additive manufacturing by determining the path that a head of 3D printer can follow while extruding a material mix of a required composition at required points of a layer of an FGM. Each point within the layer is evaluated regarding the directions within which the printing head can move into from that point while extruding the material mix of a required composition. Based on the evaluation, a multitude of polygons are defined within the polygonal shape that are guaranteed to be printable. A path can be designed for the printing head to follow to print all of the defined polygons, and consequently, to print the entire polygonal layer. Material extrusion commands are generated for the printing head.
