  • Patent number: 9889533
    Abstract: The invention provides a cloth taking-up device including: a platform, on which glue/cloth to be taken-up are disposed; and a clamp part movable with respect to the platform, which can clamp a roller and roll the glue/cloth to be taken-up successively onto the roller. An outside surface of the platform has an included angle of 0°-180° with respect to the horizontal plane, on which the glue/cloth to be taken-up are disposed, and the clamp part can keep the roller in parallel with the outside surface.

  • Publication number: 20180005562
    Abstract: Systems, methods, and devices are provided to reduce noise present in sensing circuits used for calibrating light emitting diodes (e.g., organic light emitting diodes) in electronic display devices. Such a system may include a display that renders image data using self-emissive pixels. Values on the pixels may be sensed using a current source that outputs a current and a comparator that receives the current. The comparator changes states when a voltage signal output by the capacitor crosses a first threshold voltage or a second threshold voltage. A controller receives a first time when the comparator component changes states based on the voltage signal, receives a second time when the comparator component changes states based on the voltage signal, determines a current value based on the first time and the second time, and calibrates a pixel based on the current value.
