When a touch position of an active pen on a screen of an electronic terminal is detected, and once a first touch position of the active pen on the screen of the electronic terminal is detected based on downlink signals collected by sensors under the screen of the electronic terminal, sensors outside a first preset region including the first touch position are disabled, where sensors in the first preset region are still in a working mode. In addition, a quantity of sensors in the first preset region is less than a quantity of sensors under the screen of the electronic terminal. In this way, when a second touch position of the active pen on the screen of the electronic terminal is subsequently determined, downlink signals sent by the active pen are collected only by using the sensors in the first preset region, instead of always by using all sensors under the screen of the electronic terminal, so that detection flexibility is improved.
