A method and a terminal device are provided for waking up an icon. Upon detection of a first wake event while a display screen of said terminal device is in a Screen-Off mode, the terminal device determines whether a second wake event is detected within a preset time threshold. The display screen is equipped with an under-screen fingerprint recognition circuitry in a fingerprint recognition area. Upon detection of said second wake event within said preset time threshold, the terminal device causes said display screen to switch into a Screen-On mode in which a preset icon is displayed in the fingerprint recognition area. When said second wake event is not detected within said preset time threshold, the said terminal device causes said display screen to switch into an Always on Display mode in which said preset icon is displayed in the fingerprint recognition area.
