    Abstract: Embodiments of the present disclosure provide a method of driving display, and a display device. The method of driving display includes: scanning, progressively or rows by rows, a plurality of sub-pixels arranged in an N×M array, to turn on each row of sub-pixels scanned, so that a duration in which two adjacent rows of sub-pixels are simultaneously in an ON state is greater than or equal to two times a unit scanning time, wherein the unit scanning time is a time required for scanning a row of sub-pixels, N is an integer greater than 1, and M is an integer greater than 1; and applying data signals to at least two rows of sub-pixels simultaneously in the ON state, so that a duration of applying the data signals to each row of sub-pixels is greater than the unit scanning time.

    Abstract: The present disclosure provides a phase shifter and antenna. The phase shifter includes a first substrate, a second substrate and a first dielectric layer between the first substrate and the second substrate. The first substrate includes: a first base substrate and a transmission line on a side of the first base substrate proximal to the first dielectric layer. The second substrate includes: a second base substrate and a reference electrode on a side of the second substrate proximal to the first dielectric layer. An orthographic projection of the reference electrode on the first base substrate at least partially overlaps an orthographic projection of the transmission line on the first base substrate. The reference electrode is provided with a first opening therein, and a length of the first opening along the first direction is not less than a line width of the transmission line.

    Abstract: A phase shifter includes a base substrate; a signal electrode, first and second reference electrodes all on the base substrate, and the first and second reference electrodes being respectively on two sides of a length direction of the signal electrode; an interlayer insulating layer on a side of the signal electrode away from the base substrate; and a phase control unit including a film bridge on a side of the interlayer insulating layer away from the base substrate. The signal electrode is in space enclosed by the base substrate and the film bridge, and two ends of the film bridge respectively overlap with the first and second reference electrodes in a direction perpendicular to the base substrate. The film bridge includes first and second anchor point areas and a functional area between the first and second anchor point areas, and has a hollow pattern in the functional area.
