Abstract: The present disclosure discloses an information processing method and an electronic device. The method comprises obtaining display parameters of the display unit; determining a refresh rate of the display unit based on the display parameters; setting a first period and a second period in the refresh cycle; and generating a first control instruction to control the electronic device to refresh the touch detection unit while stopping refreshing the display unit during the first period of each refresh cycle, so as to enable the touch detection unit to detect a touch operation, and control the electronic device to refresh the display unit during the second period of each refresh cycle.

Abstract: A method for displaying an icon is provided. The method for displaying an icon includes: detecting a trigger condition for displaying a target icon on a display screen; and in response to detecting the trigger condition, determining a target icon pattern from a plurality of icon patterns corresponding to the target icon. An icon display area of the display screen displays one or more of the plurality of icon patterns, and patterns of the plurality of icons are at least partially non-overlapping.

Abstract: A method and an electronic device of performing fingerprint recognition are provided. The method of performing the fingerprint recognition comprises: receiving a trigger instruction to call a fingerprint-recognition element of an electronic device; and in response to receiving the trigger instruction, activating one or more pixel units of a display screen of the electronic device to provide light at a fingerprint detection area of the display screen; detecting a fingerprint of a user of the electronic device at the fingerprint-detection area of the display screen; and determining whether or not the user is an authorized user of the electronic device from the fingerprint of the user as detected.

Abstract: Method, electronic device, and display panel for fingerprint detection are provided. A control instruction for collecting a fingerprint is obtained. The control instruction is executed to control at least one display pixel cell of a display panel to be under a fingerprint identification mode. The at least one display pixel cell of the display panel corresponds to a fingerprint collection region. The fingerprint collection region includes a partial region of the display panel. The fingerprint information in the fingerprint collection region is obtained by the at least one display pixel cell under the fingerprint identification mode.
