The present disclosure provides a request identification method and apparatus, a device, and a storage medium. The method includes: obtaining a to-be-identified access request and a frequent item set for identifying an abnormal request, the frequent item set including a target client feature obtained based on mining of historical request data, a quantity of historical request data corresponding to the target client feature being greater than a predetermined frequent threshold, and the frequent item set being an item set that passes a request timestamp distribution abnormality detection; matching client information carried in the to-be-identified access request with the target client feature included in the frequent item set to obtain a matching result; and determining, when the matching result indicates a successful match, the to-be-identified access request as an abnormal request. The abnormal request is identified based on the pre-generated frequent item set for identifying the abnormal request.

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.
