Abstract: A passive radio frequency identification (RFID) tag, including: a carrier; metal antennas, respectively disposed in mirror symmetry on a first surface and a second surface of the carrier opposite to each other, wherein a part of the metal antenna on the first surface and another part of the metal antenna on the second surface are open-circuited at one end of the carrier and short-circuited at another end of the carrier; and a RF chip, embedded in the metal antenna for transmitting and receiving a radio signal in a UHF frequency band through the metal antenna, wherein the RF chip is bonded to a PCB module. The solution of the disclosure overcomes phenomenon of deterioration and peeling of a conductive medium forming a radio frequency radiation structure, and significantly improves reliability of the passive RFID tag used in exposure to a high temperature environment for a long time.

Abstract: A radio frequency identification tag component includes a metal plate with an upper surface and a lower surface; a radiation element comprising a tag housing, the tag housing is arranged along a side of the upper surface of the metal plate, the tag housing contain therein an IC chip, an antenna and a circuit board electrically connecting the IC chip with the antenna, wherein, the antenna is made of metal, and the antenna has a first segment and a second segment parallel to the upper surface of the metal plate, there is a first spacing between the first segment and the upper surface of the metal plate, and there is a second spacing between the first segment and the second segment, and the upper surface of the metal plate is at an angle to the plane in which the antenna is located.

Abstract: A video playback method is provided, including: displaying a video playback interface, and playing a current video on the video playback interface; and in accordance with a determination that the current video is a video clip corresponding to a portion of a the target video and a video playback switching condition is satisfied: playing the target video on the video playback interface starting from a playback start time of the target video.

Abstract: A method for driving a display panel, a display panel, and a display device are provided, where in a first operating mode, a gate driver circuit is controlled for each image frame to output a scan signal to N rows of gate lines on the display panel sequentially in a preset scan direction to thereby display throughout a screen; and in a second operating mode, the gate driver circuit is controlled for each image frame to output a scan signal to m adjacent rows of gate lines on the display panel sequentially in the preset scan direction to thereby display only in an area corresponding to the m adjacent rows of gate lines without scanning the gate lines in an area in which no image may be displayed, so as to lower power consumption of the display panel operating in the second operating mode.
