ELECTRONIC DEVICE WITH TOUCH SCREEN FOR FINGERPRINT RECOGNITION

An electronic device includes a touch screen having a sensing array with a plurality of sensors, a display panel having a displaying area and a processor. The sensing area of the sensing array is smaller than or equal to the displaying area. The processor determines whether a user's finger touches an icon displayed on the display panel, and the icon corresponds to an application. When the processor determines that the user's finger touches the icon, the electronic device controls a first sensing area of the sensing array corresponding to a first displaying area of the icon to enter a fingerprint sensing mode to capture a fingerprint image of the user's finger for fingerprint recognition. When the processor determines that fingerprint recognition is approved, the processor activates the application corresponding to the icon.
