Abstract: The present disclosure provides a worktable for testing a liquid crystal panel. In one embodiment, the worktable for testing the liquid crystal panel includes: a table body, an upper surface of which being formed with a mounting groove in order to form a light-transmittance region; wherein, the table body is further formed with a slot that has an opening in a side surface of the table body and that is configured to mount a lower polarizer therein so that the lower polarizer at least covers the light-transmittance region. The present disclosure also provides a test apparatus including the mentioned worktable.

Abstract: A phase calibration method for a phased array antenna is provided. The method includes: sequentially calibrating M×N antenna units based on a pre-obtained test voltage set including first test voltages; sequentially loading the first test voltages to the antenna unit in the ith row and the jth column, and acquiring phase and amplitude information of a microwave signal radiated by the antenna unit every time one first test voltage is loaded; acquiring first array vectors through analysis based on the phase and amplitude information of the acquired microwave signals of the antenna unit under different first test voltages; obtaining a calibration response vector of the antenna unit under each first test voltage in the test voltage set through a first preset algorithm based on the first array vector, and determining a target voltage-phase curve corresponding to the antenna unit in the ith row and the jth column.

Abstract: Disclosed are an information processing method, an information processing system, an electronic device and a storage medium. The information processing method includes: receiving a plurality of pieces of item information sent by a client, each piece of item information including an occurrence time period of an item and a corresponding timing task, before the current timing task to be triggered is triggered, determining a trigger time point interval between the current timing task to be triggered and the next timing task to be triggered; and based on the trigger time point interval and the sequence of the occurrence time periods, determining a target timing task from the current timing task to be triggered and the next timing task to be triggered, and updating, at a trigger time point of the target timing task, the item list displayed on the terminal.
