  • Publication number: 20220322511
    Abstract: A backlight control circuit is provided, which includes a driver circuit and a power conversion circuit. The driver circuit includes a feedback output terminal and at least one channel port. The channel port is coupled to a first terminal of a light string group. The driver circuit is configured to obtain a voltage of each channel port, and enable the feedback output terminal to provide a current feedback signal based on the voltage Vch. The power conversion circuit is coupled to the feedback output terminal and includes a voltage output terminal. The voltage output terminal is configured to provide a supply voltage for a second terminal of each light string group. The power conversion circuit is configured to perform voltage conversion on an input voltage, and increase or decrease the supply voltage based on the current feedback signal.

  • Patent number: 11308305
    Abstract: 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.
