Abstract

Disclosed in various embodiments of the present invention are a method and a device, the device comprising a touch sensing module, a memory and a processor, wherein the processor is configured to detect a touch input while a low-power display mode is driven, store, in the memory, touch data corresponding to the detected touch input, change the low-power display mode to another designated mode, reset a touch baseline of the touch sensing module in response to the mode change, and compensate for the touch strength of the stored touch data at least on the basis of the designated mode. Various embodiments are possible.

First claim

The invention claimed is:

1. An electronic device comprising:
a touch sensing module;
a memory; and
a processor,
wherein the processor is configured to:
detect a touch input while driving a low-power display mode,
store, in the memory, touch data corresponding to the detected touch input,
change the low-power display mode to a predetermined mode different from the low-power display mode,
reset a touch baseline of the touch sensing module corresponding to the mode change,
compensate for a touch strength of the stored touch data at least based on the predetermined mode, and
change a capacitor value in the low-power display mode to a value in a range corresponding to a capacitor value in the predetermined mode based on the touch data.

2. The electronic device of claim 1 ,
wherein the predetermined mode comprises a normal display mode, and
wherein the processor is configured to switch the low-power display mode to the normal display mode after storing the touch data.

3. The electronic device of claim 1 , wherein the processor is configured to perform a function based on a touch gesture being input after the touch strength is compensated for.

4. The electronic device of claim 1 , wherein the processor is configured to switch the low-power display mode to the predetermined mode in case that the detected touch input is released.

5. The electronic device of claim 1 , wherein the processor is configured to:
delay the touch baseline reset when the touch input is detected; and
reset the touch baseline when the detected touch input is released.

6. The electronic device of claim 1 , wherein the processor is configured to:
switch the low-power display mode to the predetermined mode when the touch input is detected; and
perform a function based on the released position when the detected touch input is released.

7. The electronic device of claim 1 , further comprising a sensor,
wherein the processor is configured to:
detect sensor data using the sensor while driving the low-power display mode,
switch the low-power display mode to a normal display mode, and
perform a function based on the sensor data.

8. The electronic device of claim 7 , wherein the processor is configured to:
detect the touch input after switching to the normal display mode; and
process the touch input as an effective gesture based on whether the touch input is within a predetermined distance from the sensor data.

9. The electronic device of claim 8 , wherein the processor is configured to:
process the touch input as the effective gesture in case that the touch input is within the predetermined distance from the sensor data; and
perform a function corresponding to the effective gesture.

10. The electronic device of claim 7 , wherein the processor is configured to:
detect the touch input after switching to the normal display mode; and
process the touch input as an effective gesture based on whether the sensor data is detected.

11. A method for operating an electronic device, the method comprising:
driving a low-power display mode;
detecting a touch input;
storing touch data corresponding to the detected touch input;
changing the low-power display mode to a predetermined mode different from the low-power display mode;
resetting a touch baseline corresponding to the mode change; and
compensating for a touch strength of the stored touch data at least based on the predetermined mode,
wherein compensating comprises changing a capacitor value in the low-power display mode to a value in a range corresponding to a capacitor value in the predetermined mode based on the touch data.

12. The method of claim 11 ,
wherein the predetermined mode includes a normal display mode, and
wherein the method further comprises switching the low-power display mode to the normal display mode after storing the touch data.

13. The method of claim 11 , further comprising performing a function based on a touch gesture being input after the touch strength is compensated for.
