Apparatus and method for providing memo function
An electronic device is provided. The electronic device includes a display, an electronic pen, a slot in which the electronic pen can be inserted in or detached from, a pen sensing module configured to sense an insertion/detachment of the electronic pen, a pen input module configured to receive an input using the electronic pen, and a processor configured to activate the pen input module while the display maintains an OFF-state when the detachment of the electronic pen is sensed within the OFF-state of the display.
1. An electronic device comprising:
a display;
a pen;
a slot in which the pen can be inserted or detached;
a pen sensor;
a pen input interface; and
at least one processor electrically connected to the display, the pen sensor, and the pen input interface,
wherein the at least one processor is configured to:
while the display is in an OFF-state, sense via the pen sensor, at least a partial detachment of the pen from the slot,
in response to the at least the partial detachment of the pen during the OFF-state of the display being sensed, activate the pen input interface and display a memo screen with a black color background,
sense an insertion of the pen into the slot while the memo screen with the black color background is displayed, and
in response to the insertion of the pen into the slot being sensed, display a first screen when the electronic device is in a locked state and display a second screen different from the first screen when the electronic device is not in the locked state.
2. The electronic device of claim 1 , wherein, in response to the insertion of the pen being sensed, the at least one processor is further configured to store the memo screen.
3. The electronic device of claim 2 , wherein the at least one processor is further configured to display the stored memo screen in response to a memo application being executed.
4. The electronic device of claim 1 , wherein the first screen comprises a lock screen.
5. The electronic device of claim 1 , wherein the second screen comprises a screen that was displayed before the display entered the OFF-state.
6. The electronic device of claim 5 , wherein the screen that was displayed before the display entered the OFF-state comprises a home screen.
7. The electronic device of claim 1 ,
wherein, in response to the at least the partial detachment of the pen during the OFF-state of the display being sensed, the at least one processor is further configured to display the memo screen including a first area receiving a stroke input and a second area including at least one control menu with respect to the stroke input, and
wherein the at least one control menu comprises a save menu with respect to a memo input to the first area.
8. The electronic device of claim 1 , wherein the at least one processor is further configured to:
sense, via the pen input interface, a pen stroke input on the memo screen, and
display the pen stroke input in a white color over the black color background of the memo screen.
9. The electronic device of claim 1 , wherein the display is implemented by an active matrix organic light-emitting diode (AMOLED).
10. A method of providing a memo function of an electronic device, the method comprising:
while a display of the electronic device is in an OFF-state, sensing, via a pen sensor of the electronic device, at least a partial detachment of a pen from a slot of the electronic device;
in response to the sensing of the at least the partial detachment of the pen during the OFF-state of the display, activating an input interface of the pen and displaying a memo screen with a black color background;
sensing an insertion of the pen into the slot while the memo screen with the black color background is displayed; and
in response to the sensing of the insertion of the pen into the slot, displaying a first screen when the electronic device is in a locked state or displaying a second screen when the electronic device is not in the locked state.
11. The method of claim 10 , further comprising:
in response to the sensing of the insertion of the pen into the slot, storing the memo screen.
12. The method of claim 11 , further comprising:
displaying the stored memo screen on a memo application in response to the memo application being executed.
13. The method of claim 10 , wherein the first screen comprises a lock screen.
14. The method of claim 10 , wherein a screen that was displayed before the display entered the OFF-state comprises a home screen.
