  • Publication number: 20230084423
    Abstract: Embodiments presented herein relate to reducing visual artifacts on an electronic display caused by an intra-frame pause. To do so, the intra-frame pause may be divided into smaller intra-frame pause segments. The intra-frame pause segments may be applied to the display during different image frames and/or at different locations on the electronic display. For example, each intra-frame pause segment may be applied to a different location on the electronic display. In some embodiments, multiple intra-frame pause segments may be applied during a single image frame. In some embodiments, the intra-frame pause segments may be applied to various image frames and at various location on the electronic display according to a pattern. To reduce band flickering that may be caused by the different locations of the intra-frame pause segments, an emission duty of one or more rows of pixels of the display may be adjusted.

  • Publication number: 20230079326
    Abstract: Aspects of the disclosure relate to identifying legitimate websites and removing false positives from domain discovery analysis. Based on a list of known legitimate domains, a computing platform may generate a baseline dataset of feature vectors corresponding to the known legitimate domains. Subsequently, the computing platform may receive information identifying a first domain for analysis and may execute one or more machine learning algorithms to compare the first domain to the baseline dataset. Based on execution of the one or more machine learning algorithms, the computing platform may generate first domain classification information indicating that the first domain is a legitimate domain. In response to determining that the first domain is a legitimate domain, the computing platform may send one or more commands directing a domain identification system to remove the first domain from a list of indeterminate domains maintained by the domain identification system.
