A projection method and a terminal device, including responding, by a transmit end, to a screen projection instruction, obtaining a real-time interface of an application program on which screen projection is to be performed and device information of one or more receive ends, obtaining a user experience score of each receive end of the one or more receive ends by scoring a visual effect, sound effect, and interaction complexity of each receive end based on the device information, obtaining, based on the user experience score, first data on which screen projection is to be performed and that is at least one of a video stream, an audio stream, or a user interface control, obtaining a control layout file of the user interface control in response to the first data having the user interface control, and sending, to a corresponding receive end, the first data and the control layout file.

This application provides a fingerprint collection apparatus. According to the fingerprint collection method and the related apparatus that are provided in this application, a sensor array is divided into a plurality of areas in terms of a column based on a quantity of input ports of an analog front end component and a quantity of columns of the sensor array, and sensor units in different areas multiplex input channels of the analog front end component by using switches. In this way, when scanning row scanning lines in the sensor array, a row scanning circuit may control the switches to output, to the analog front end component in a time division manner, original fingerprint data collected by the sensor units in the different areas, so that fewer input channels of the analog front end component can be required, and a size of a fingerprint collection apparatus can be reduced.
