摘要： The present invention provides a terminal antenna and a terminal. The terminal antenna includes a mainboard, a feedpoint disposed on the mainboard, a metal housing, an adjustable apparatus, and at least two adjustable ground points. The mainboard is located on an inner side of the metal housing, the metal housing is electrically connected to the mainboard, and a slot is disposed in the metal housing. The feedpoint and the at least two adjustable ground points each are disposed on a part of the mainboard facing the slot. The at least two adjustable ground points each are electrically connected to the mainboard by using the adjustable apparatus, and the adjustable apparatus is configured to control whether each adjustable ground point is grounded. In embodiments of the present invention, the adjustable apparatus controls whether each adjustable ground point is grounded, so that signals with a same frequency can be radiated from a first end and a second end of the slot of the terminal antenna. This avoids a prior-art problem of low efficiency of a terminal antenna caused because a low-frequency signal or a high-frequency signal radiated by the terminal antenna is rapidly attenuated when a slot in a metal housing is covered by a hand.

摘要： This application relates to a face image displaying method, a readable storage medium, a program product, and an electronic device. The method includes: A first electronic device obtains a first face image acquired by a first camera at a first moment, where a face in the first face image is at a first position. A second electronic device displays a second face image, where the second face image is an image obtained by converting the first face image based on an imaging mapping relationship between the first camera and the second camera, and a position of the face in the second face image is the same as a position of the face in an image acquired by the second camera at the first moment. The method provided in this application is applied, so that a position of the face in a preview image displayed by the second electronic device may be consistent with a position of the face in the face image that is shot by the second camera and that is used as a face for facial recognition. In this way, the position of the face in the preview image can accurately reflect the position of the face in the face image shot by the second camera, thereby improving efficiency and accuracy of face registration.

摘要： An electro-optic modulator, an optical chip, and an integrated chip are provided. The electro-optic modulator is disposed on a surface of a substrate (01). The electro-optic modulator includes: an optical waveguide layer (002) disposed on the substrate (01), a modulation electrode (003) disposed on the optical waveguide layer (002), and a metal electrode (004) disposed on the modulation electrode (003) and electrically connected to the modulation electrode (003). A first end of the metal electrode (004) is coupled to a radio frequency driver, and receives a modulation signal input by the radio frequency driver. The modulation electrode (003) is configured to perform electro-optic modulation on the optical waveguide layer (002) based on the modulation signal. A second end of the metal electrode (004) is coupled to a direct-current voltage end, and the direct-current voltage end is configured to input a voltage signal and provide a bias voltage for the radio frequency driver by using the metal electrode (004). The electro-optic modulator multiplexes the metal electrode (004), and a complex peripheral circuit does not need to be disposed. This reduces costs and a size of the electro-optic modulator, and is conducive to device miniaturization.
