Abstract

An electronic device includes a display including a plurality of regions, a display driver integrated circuit configured to drive a first region of the display at a first driving frequency and drive a second region of the display at a second driving frequency according to a configuration of the display, and a processor configured to provide display data to the display driver integrated circuit. The processor identifies a driving frequency of a first screen to be output on the display in response to reception of a first input; and controls the display to output at least a portion of the first screen on a region, of the plurality of regions, driven at a driving frequency corresponding to the driving frequency of the first screen. The display optimizes driving frequency, thus reducing heating problems and resource waste in the electronic device.

First claim

What is claimed is:

1. An electronic device, comprising:
a display comprising a plurality of regions;
a display driver integrated circuit configured to drive a first region of the plurality of regions at a first driving frequency and drive a second region of the plurality of regions at a second driving frequency according to a configuration of the display; and
a processor configured to provide display data to the display driver integrated circuit,
wherein the processor is configured to:
identify a driving frequency of a first screen to be output on the display in response to reception of a first input,
control the display to output at least one portion of the first screen on the first region driven at a driving frequency corresponding to the driving frequency of the first screen, and
drive the second region at a driving frequency corresponding to a second screen, while overlaying and outputting the second screen over at least another portion of the first screen on the second region, in response to reception of a second input.

2. The electronic device of claim 1 , wherein the processor is further configured to:
identify an application to be executed in response to the first input, and
output the first screen on the first region based on execution of the application when the application is configured to operate at the first driving frequency.

3. The electronic device of claim 1 , wherein the processor is further configured to:
identify an application to be executed in response to the first input, and
output the at least other portion of the first screen on the second region based on execution of the application when the application is configured to operate at the second driving frequency.

4. The electronic device of claim 1 , wherein the processor is further configured to:
identify a size of the first screen to be output on the display,
select a region of the plurality of regions corresponding to the size of the first screen, when a size of the region driven at the driving frequency corresponding to the driving frequency of the first screen is different from the size of the first screen, and
change a driving frequency of the selected region based on the driving frequency of the first screen.

5. The electronic device of claim 1 , wherein the processor is further configured to:
identify a size of the first screen to be output on the display, and
output the first screen over the first region and the second region, when the size of the first screen is greater than a size of each of the first region and the second region, and output the first screen at a driving frequency greater than the driving frequency of each of the first region and the second region.

6. The electronic device of claim 1 , wherein the processor is further configured to:
identify a size of the first screen to be output on the display,
output the first screen over the first region and the second region, when the size of the first screen is greater than a size of each of the first region and the second region, and
change driving frequencies of the first region and the second region over which the first screen is output, based on the driving frequency of the first screen.

7. The electronic device of claim 1 , wherein the processor is further configured to:
execute a first application in response to the first input,
output the first screen on the first region based on the execution of the first application,
execute a second application in response to the second input, when the second input is received, and
drive the second region at the second driving frequency while outputting at least a portion of the second screen on the second region, based on the execution of the second application.

8. The electronic device of claim 1 , wherein the processor is further configured to:
execute a first application in response to the first input,
output the first screen over the first region and the second region based on the execution of the first application,
execute a second application in response to the second input, when the second input is received, and
drive the second region at the second driving frequency, while overlaying and outputting the second screen over the at least other portion of the first screen on the second region, based on the execution of the second application.

9. The electronic device of claim 8 , wherein the processor is further configured to:
drive the first region at the first driving frequency, while adjusting a size of the first screen and outputting the first screen on the first region.

10. The electronic device of claim 1 , further comprising:
a first housing in which a first part of the display is located;
a second housing in which a second part of the display is located; and
a hinge structure connecting the first housing with the second housing,
wherein the first region of the display corresponds to at least the first part of the display, and
wherein the second region of the display corresponds to at least the second part of the display.

11. An electronic device, comprising:
a display comprising a plurality of regions;
a display driver integrated circuit configured to drive a first region of the plurality of regions at a first driving frequency and drive a second region of the plurality of regions at a second driving frequency according to a configuration of the display; and
a processor configured to provide display data to the display driver integrated circuit,
wherein the processor is configured to:
identify a driving frequency of a first screen to be output on the display in response to reception of a first input,
control the display to output at least one portion of the first screen on the first region driven at a driving frequency corresponding to the driving frequency of the first screen, and
drive the first region at the first driving frequency, while overlaying and outputting the second screen over at least another portion of the first screen on the first region, in response to reception of a second input.

12. The electronic device of claim 11 , wherein the processor is further configured to:
execute a first application in response to the first input,
output the first screen on the first region based on the execution of the first application,
execute a second application in response to the second input, when the second input is received, and
drive the first region at the first driving frequency, while overlaying and outputting the second screen over the at least other portion of the first screen on the first region, based on the execution of the second application.

13. The electronic device of claim 11 , wherein the processor is further configured to:
execute a first application in response to the first input, and
output the first screen over the first region and the second region based on the execution of the first application.
