  • Patent number: 10706808
    Abstract: Provided is a video signal line driver circuit capable of displaying a video with a high viewing quality even when gradation voltages of the same value are simultaneously selected as analog video signals. A voltage ladder 87 of a source driver 50 has formed therein gradation voltage supplement lines 91 extending to the outside of the source driver 50 from output terminals for outputting generated gradation voltages. The gradation voltage supplement lines 91 are grounded outside the source driver 50 via voltage supplement capacitors 90. Accordingly, even when gradation voltages of the same value are simultaneously selected as analog video signals, the voltage supplement capacitors 90 provide necessary current supplement to the voltage ladder 87, thereby inhibiting potential drop across the output terminals for outputting gradation voltages.

  • Patent number: 10656722
    Abstract: This document describes a system for animating a two-dimensional object in real-time with gestural data collected by a gestural sensor of the system. A gestural sensor collects gestural data. An image extraction engine extracts image data that renders a two-dimensional object on a display device of the system. An overlay engine generates a mesh overlay for the two-dimensional object. Based on a detected gesture represented in the gestural data collected, an animation engine modifies portions of the two-dimensional object from a first image frame to a second image frame based on the collected gestural data. An image frame generator generates the first and second image frames that animate the two-dimensional object in accordance with the gestural data collected.
