2. The electronic device of claim 1 ,

wherein the first cover includes an outer cover configured to protect the display module against an external impact, and

wherein, in the case of using an electronic pen, the second cover includes an inner cover configured to improve handwriting feelings.

3. The electronic device of claim 1 ,

wherein the second cover is transparently implemented and constructed from at least one material of thermos plastic polyurethane (TPU), polycarbonate (PC), and silicone.

4. The electronic device of claim 3 ,

wherein the second cover is implemented by injection and constructed from a material that causes a surface of the second cover to have a paper texture.

5. The electronic device of claim 1 , wherein the at least one sensor module further comprises,

a first hall sensor and a second hall sensor,

wherein the processor is configured to:

identify the sensing information on the first cover by using the first hall sensor, and

identify the sensing information on the second cover by using the second hall sensor.

6. The electronic device of claim 5 ,

wherein a first magnetic member is disposed on the first cover corresponding to the first hall sensor, and a second magnetic member is disposed on the second cover corresponding to the second hall sensor.

7. The electronic device of claim 1 , wherein additional magnetic members are disposed at locations corresponding to the first cover and the second cover so that the first cover and the second cover are magnetically attachable to each other.

8. The electronic device of claim 1 , wherein the configuration information on the display module includes at least one of color, brightness, contrast, balance, saturation, and sharpness of the display module.

9. The electronic device of claim 1 , wherein the processor is configured to:

in the case that the first cover is in the open state and the second cover is in the closed state, execute at least one application stored in the memory related to usage of an electronic pen, and

obtain a handwriting input of the electronic pen through the second cover.

10. The electronic device of claim 9 , wherein the processor is configured to:

store the obtained handwriting input in the memory in the case that the first cover is changed to the closed state in a state in which the first cover is in the open state and the second cover is in the closed state.

11. The electronic device of claim 9 ,

store the obtained handwriting input in the memory, and display a lock screen through the display module in the case that the second cover is changed to the open state in a state in which the first cover is in the open state and the second cover is in the closed state.

12. The electronic device of claim 1 , wherein the accessory cover further comprises a short-range communication antenna, and

wherein the processor is configured to:

identify the short-range communication antenna through the communication module, and

detect that the short-range communication antenna has been mounted on the accessory cover.

13. A method comprising:

detecting equipment for an accessory cover using a communication module;

identifying sensing information on a first cover and a second cover included in the accessory cover by using at least one sensor module; and

changing configuration information on a display module in the case that the first cover is in an open state and the second cover is in a closed state based on the identified sensing information.

14. The method of claim 13 ,

wherein the first cover includes an outer cover configured to protect the display module against an external impact, and

wherein the second cover includes an inner cover configured to improve handwriting feelings in the case of using an electronic pen.

15. The method of claim 13 , wherein the second cover is transparently implemented and is constructed from at least one of thermos plastic polyurethane (TPU), polycarbonate (PC), and silicone, and is implemented by injection and is constructed from a material to cause a surface of the second cover to have a paper texture.

16. The method of claim 13 ,

wherein the at least one sensor module includes a first hall sensor and a second hall sensor,

wherein identifying the sensing information includes:

identifying the sensing information on the first cover by using the first hall sensor; and

identifying the sensing information on the second cover by using the second hall sensor.

17. The electronic device of claim 16 ,

wherein a first magnetic member is disposed on the first cover corresponding to the first hall sensor, and a second magnetic member is disposed on the second cover corresponding to the second hall sensor.

18. The electronic device of claim 13 , wherein the configuration information on the display module includes at least one of color, brightness, contrast, balance, saturation, and sharpness of the display module.

19. The method of claim 13 , further comprising:

executing at least one application stored in a memory and related to usage of an electronic pen in the case that the first cover is in the open state and the second cover is in the closed state; and

obtaining a handwriting input of the electronic pen through the second cover.

20. The method of claim 19 , further comprising:

storing the obtained handwriting input in the memory in the case that the first cover is changed to the closed state in a state in which the first cover is in the open state and the second cover is in the closed state; and

storing the obtained handwriting input in the memory, and displaying a lock screen through the display module in the case that the second cover is changed to the open state in a state in which the first cover is in the open state and the second cover is in the closed state.
