  • Patent number: 12256626
    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 print head/substrate scan offsets, offsets between print heads, the use of different nozzle drive waveforms, and/or other techniques. Optionally, patterns of fill variation can be introduced so as to mitigate observable line effects in a finished display device. The disclosed techniques have many other possible applications.

  • Publication number: 20250016491
    Abstract: An stylus includes a housing that defines a force input surface opposite a touch input surface. A spring member in the housing includes a first arm that biases a touch sensor toward the touch input surface. The spring member also includes a second arm that biases a first force electrode toward the housing and allows the first force electrode to move toward a second force electrode when a force is applied to the force input surface. A non-binary amount of the force is determinable using a change in a mutual capacitance between the first force electrode and the second force electrode. The mutual capacitance between the first force electrode and the second force electrode may be measured upon detecting a touch using the touch sensor.

  • Patent number: 12103182
    Abstract: A wearable device may include an article configured to be worn by a user and a sensor array coupled with the article. The sensor array may be configured to obtain force data, among other data. A system can receive information generated by the wearable device utilized to perform a task. The information may include motion data indicating a motion of the wearable device and the force data indicating a force applied to the wearable device. The force data may be obtained from the sensor array generating digital outputs. The system can control a robotic device to perform a robotic motion based on the motion data and apply a robotic force based on the force data to repeat the task. The robotic device may include a sensor array to determine a force applied to the robotic device for controlling the robotic force. Other aspects are also described and claimed.

  • Publication number: 20230234087
    Abstract: A repeatable manufacturing process uses a printer to deposits liquid for each product carried by a substrate to form respective thin films. The liquid is dried, cured or otherwise processed to form from the liquid a permanent layer of each respective product. To perform printing, each newly-introduced substrate is roughly mechanically aligned, with an optical system detecting sub-millimeter misalignment, and with software correcting for misalignment. Rendering of adjusted data is performed such that nozzles are variously assigned dependent on misalignment to deposit droplets in a regulated manner, to ensure precise deposition of liquid for each given area of the substrate. For example, applied to the manufacture of flat panel displays, software ensures that exactly the right amount of liquid is deposited for each “pixel” of the display, to minimize likelihood of visible discrepancies in the resultant display.

  • Publication number: 20230147887
    Abstract: An ink jet process is used to deposit a material layer to a desired thickness. Layout data is converted to per-cell grayscale values, each representing ink volume to be locally delivered. The grayscale values are used to generate a halftone pattern to deliver variable ink volume (and thickness) to the substrate. The halftoning provides for a relatively continuous layer (e.g., without unintended gaps or holes) while providing for variable volume and, thus, contributes to variable ink/material buildup to achieve desired thickness. The ink is jetted as liquid or aerosol that suspends material used to form the material layer, for example, an organic material used to form an encapsulation layer for a flat panel device. The deposited layer is then cured or otherwise finished to complete the process.
