Patents by Inventor Sunqi Lou

Sunqi Lou has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20260044235
    Abstract: A driving method and a driving device for a touch panel, and a display apparatus are provided, featuring a low power wake-up gesture mode. In this mode, the touch panel includes a first stage for touch scanning and a subsequent second phase for pulling up the signal potential. The method involves responding to confirmation of the touch panel transitioning from the first stage to the second stage by controlling a reset signal and a low voltage signal to switch to first level signals, and controlling the start pulse signal, clock signal, and latch signal to switch to second level signals, where the voltage of the first level signal is higher than that of the second level signal. This configuration can reduce disturbances from high voltage signals to the touch scanning signal, improve issues related to failed wake-ups or accidental wake-ups, and enhance the product usage experience.
