  • Patent number: 12272292
    Abstract: A method for controlling voltage output is disclosed. The method is used to control a power supply module to provide a required operating voltage to a display panel, and a display frame of the display panel comprises a plurality of sequential row driving periods, each row driving period comprising a charging period and a non-charging period, wherein during the charging period, a connection between a data line and a corresponding row of sub-pixels is enabled so that data voltages are written into the corresponding sub-pixels. The method comprises controlling the power supply module to output an operating voltage at a preset first operating frequency during a display of a picture to be displayed, wherein a time period during which the power supply module outputs the operating voltage to the display panel does not overlap with the charging period of each row driving period.

  • Patent number: 11829276
    Abstract: Embodiments include herein are directed towards a system and method for monitoring compliance patterns. Embodiments may include a re-timer device-under-test configured to transmit a truncated compliance pattern associated with a PCIe compliance mode. Embodiments may further include a BFM monitor configured to receive the truncated compliance pattern and to identify a communication signal associated with the truncated compliance pattern. The BFM monitor may be further configured to discard at least one unexpected symbol on at least one lane associated with the communication signal and to collect compliance patterns on all lanes of the communication signal. The BFM monitor may be further configured to align one or more lane FIFOs based upon skew and to enable one or more compliance pattern checkers.
