Abstract: A piezoelectric thin film suspended above a carrier substrate is adapted to propagate an acoustic wave in a Lamb mode excited by a component of an electric field that is oriented in a longitudinal direction along a length of the piezoelectric thin film. A first signal electrode is located on the piezoelectric thin film and oriented in a transverse direction perpendicular to the longitudinal direction. A first ground electrode is located on the piezoelectric thin film and oriented in the transverse direction. The first ground electrode is separated from the first signal electrode by a gap in which the acoustic wave resonates. A first release window and a second release window are located at a first end and a second end of the piezoelectric thin film, respectively. Intermittent release windows are located beyond distal ends of the first signal electrode and the first ground electrode.

Abstract: A photographing processing method and apparatus, an electronic device, and a readable storage medium, and pertains to the field of photographing technologies. The photographing processing method includes: performing automatic focus on a first preview image displayed on a photographing preview interface, to obtain first focusing information, and updating the first preview image to a second preview image corresponding to the first focusing information; receiving a first input; in response to the first input, adjusting the first focusing information to obtain second focusing information, and updating the second preview image to a third preview image corresponding to the second focusing information; and performing photographing on the third preview image according to the second focusing information.

Abstract: A display control method and a terminal are provided. The method includes: receiving a first input of a user on a first screen; switching a first program interface of a first program from being displayed on a second screen to being displayed on the first screen in response to the first input; and displaying a first floating window on the second screen. A first display content in the first floating window is updated synchronously with a second display content of the first program interface.
