detect that the power button is pressed when the touch screen is in the lock screen state; and

display, via the touch screen, the fingerprint pattern in the target display area in response to detecting that the power button is pressed when the touch screen is in the lock screen state.

6. The mobile phone of claim 1 , wherein the instructions further cause the processor to be configured to power on the in-display fingerprint sensor when the fingerprint pattern is displayed.

7. The mobile phone of claim 1 , wherein the instructions further cause the processor to be configured to avoid activating the in-display fingerprint sensor in response to detecting the second tap on the touch screen when the touch screen is in the lock state, while the mobile phone is in a voice call state.

8. A non-transitory computer readable medium configured to store a computer program product comprising computer executable instructions that, when executed by a processor of a mobile device, cause the processor to:

display, via the touch screen, a fingerprint pattern in a target display area in response to detecting a first tap when the touch screen is in a lock screen state or detecting that the mobile phone is picked up when the touch screen is in the lock screen state, wherein the fingerprint pattern is used to prompt a user to enter a fingerprint;

receive a voice call when the touch screen is in the lock screen state while the fingerprint pattern is displayed in a target display area;

remove the fingerprint pattern from the target display area to stop the fingerprint pattern from being displayed in the target display area in response to receiving a voice call when the touch screen is in the lock screen state;

detect a second tap on the touch screen when the touch screen is in the lock screen state, while the mobile phone is in a voice call state; and

maintain display, via the touch screen, of the target display area, with the fingerprint pattern being excluded from the target display area, in response to detecting the second tap on the touch screen when the touch screen is in the lock screen state, while the mobile phone is in the voice call state.

9. The non-transitory computer readable medium of claim 8 , wherein the computer executable instructions further cause the processor to:

detect, using a proximity sensor of the mobile phone, that an object is within a first distance from an earpiece of the mobile phone, while the mobile phone is in the voice call state; and

avoid displaying the fingerprint pattern in the target display area to keep the touch screen in the lock screen state when the proximity sensor detects that the object is within the first distance from the earpiece.

10. The non-transitory computer readable medium of claim 8 , wherein to display the fingerprint pattern in the target display area, the computer executable instructions further cause the processor to:

light up the target display area with a first color; and

light up an edge of the target display area with a second color, wherein the first color is different than the second color.

11. The non-transitory computer readable medium of claim 8 , wherein the computer executable instructions further cause the processor to:

detect a floating gesture when the touch screen is in the lock screen state; and

display, via the touch screen, the fingerprint pattern in the target display area in response to detecting the floating gesture when the touch screen is in the lock screen state.

12. The non-transitory computer readable medium of claim 8 , wherein the computer executable instructions further cause the processor to be configured to avoid activating the in-display fingerprint sensor in response to detecting the second tap on the touch screen when the touch screen is in the lock state, while the mobile phone is in a voice call state.

13. The non-transitory computer readable medium of claim 8 , wherein the computer executable instructions further cause the processor to:

detect that a power button of the mobile phone is pressed when the touch screen is in the lock screen state; and

display, via the touch screen, the fingerprint pattern in the target display area in response to detecting that the power button is pressed when the touch screen is in the lock screen state.

14. The non-transitory computer readable medium of claim 8 , wherein computer executable instructions further cause the processor to power on an in-display fingerprint sensor when the fingerprint pattern is displayed.

15. An electronic device, comprising:

a touch screen with an in-display fingerprint sensor;

a processor coupled to the touch screen and the in-display fingerprint sensor; and

a non-transitory computer-readable medium storing instructions that, when executed by the processor, are configured to cause the electronic device to:

detect a first tap on the touch screen when the touch screen is in a lock screen state;

display, via the touch screen, a fingerprint pattern in the target display area in response to detecting the first tap when the touch screen is in the lock screen state, wherein the fingerprint pattern is used to prompt a user to enter a fingerprint;

detect that the electronic device is picked up when the touch screen is in the lock screen state;

display, via the touch screen, the fingerprint pattern in the target display area in response to detecting that the electronic device is picked up when the touch screen is in the lock screen state;

detect a second tap on the touch screen when the touch screen is in the lock state, while the mobile phone is in a voice call state; and

avoid activating the in-display fingerprint sensor in response to detecting the second tap on the touch screen when the touch screen is in the lock state, while the mobile phone is in a voice call state.

16. The electronic device of claim 15 , further comprising:

a proximity sensor; and

an earpiece,

wherein the instructions further cause the electronic device to:

detect, using the proximity sensor, that an object is within a first distance from the earpiece, while the electronic device is in a voice call state; and

avoid displaying the fingerprint pattern in the target display area to keep the touch screen in the lock screen state when the proximity sensor detects that the object is within the first distance from the earpiece.

17. The electronic device of claim 15 , wherein, to display the fingerprint pattern in the target display area, the instructions further cause the electronic device to:
