Abstract

An electronic device is provided. The electronic device includes a display for outputting a screen and a processor operatively connected to the display. The processor is configured to receive a user input associated with movement of a screen output on the display, detect a screen movement speed corresponding to the user input associated with the screen movement, determine an amount of screen tilt compensation corresponding to the screen movement based on the screen movement speed, when the screen movement speed is included in a first interval, and keep the amount of screen tilt compensation based on the screen movement speed constant, when the screen movement speed is included in a second interval faster than the first interval.

First claim

What is claimed is:

1. An electronic device, comprising:
a display; and
at least one processor operatively connected to the display,
wherein the at least one processor is configured to:
receive a user input associated with movement of a screen, the screen output on the display, and
detect a screen movement speed corresponding to the user input associated with the screen movement,

wherein the at least one processor is further configured to:
apply an amount of screen tilt compensation to the screen, the amount of screen tilt compensation determined according to an amount of change of the screen movement speed during a first range of the screen movement speed,
maintain the amount of screen tilt compensation independent of a change of the screen movement speed during a second range of the screen movement speed, and
output the screen without applying the screen tilt compensation during a third range of the screen movement speed,

wherein a screen movement speed of the third range is faster than a screen movement speed of the second range, and
wherein the screen movement speed of the second range is faster than a screen movement speed of the first range.

2. The electronic device of claim 1 , wherein the amount of screen tilt compensation comprises 0, when the amount of screen tilt compensation is maintained.

3. The electronic device of claim 1 , wherein the amount of screen tilt compensation includes a specific value other than 0, when the amount of screen tilt compensation is maintained.

4. The electronic device of claim 1 , wherein a change in the amount of screen tilt compensation corresponding to the screen movement speed is a linear change, when determining the amount of screen tilt compensation corresponding to the screen movement based on the screen movement speed in the first range.

5. The electronic device of claim 1 , wherein a change in the amount of screen tilt compensation corresponding to the screen movement speed is a non-linear change, when determining the amount of screen tilt compensation corresponding to the screen movement based on the screen movement speed in the first range.

6. The electronic device of claim 1 , wherein the at least one processor is further configured to:
determine a number to equally divide a current screen frame, of the screen, into screen regions according to the amount of screen tilt compensation,
divide each of the equally divided screen regions into a central region, a data copy region, and a data truncation region in the current screen frame, and
perform an operation of adding a certain amount of data to, and displaying the certain amount of data in, the data copy region, and removing the certain amount of data from the data truncation region while moving the central region in a direction opposite to the movement of the screen.

7. The electronic device of claim 6 , wherein the at least one processor differently assigns sizes of the data copy region and the data truncation region according to the amount of screen tilt compensation.

8. The electronic device of claim 6 ,
wherein the data copy region is a region disposed in a first direction of the display, when the screen movement direction is from the first direction to a second direction,
wherein the data truncation region is a region disposed in the second direction of the display, when the screen movement direction is from the first direction to the second direction,
wherein the data copy region is a region disposed in the second direction of the display, when the screen movement direction is from the second direction to the first direction, and
wherein the data truncation region is a region disposed in the first direction of the display, when the screen movement direction is from the second direction to the first direction.

9. The electronic device of claim 8 , wherein the region disposed in the first direction and the region disposed in the second direction vary in size with respect to a location of an equally divided screen region of the equally divided screen regions.

10. The electronic device of claim 9 , wherein the at least one processor is further configured to assign a data copy region of screen regions being updated earlier by a gate driver to be larger or smaller than a data copy region of screen regions being updated later by the gate driver.

11. The electronic device of claim 9 , wherein the at least one processor is further configured to assign a data truncation region of screen regions being updated earlier by a gate driver to be smaller or greater than a data truncation region of screen regions being updated later by the gate driver.

12. The electronic device of claim 6 ,
wherein the at least one processor divides a plurality of pixel lines included in the data copy region into a plurality of groups and generates data to be added through interpolation of pixel lines in each of the plurality of groups, and
wherein the certain amount of the data to be added is differently determined with respect to a location of an equally divided screen region of the equally divided screen regions.

13. The electronic device of claim 6 ,
wherein the at least one processor divides a plurality of pixel lines included in the data truncation region into a plurality of groups and determines the certain amount of the data to be removed, using data on respective pixel lines included in the plurality of groups, and
wherein the certain amount of the data to be removed is differently determined with respect to a location of an equally divided screen region of the equally divided screen regions.

14. The electronic device of claim 6 , wherein the at least one processor is further configured to assign a larger number to equally divide the current screen frame as the amount of screen tilt compensation increases.

15. The electronic device of claim 6 , wherein the at least one processor is further configured to:
extract a region of interest (ROI) from the screen displayed on the display; and
add and remove the certain amount of data within the ROI.

16. The electronic device of claim 6 , wherein the at least one processor is further configured to detect the screen movement speed based on a change in pixel information on a segment connecting a first point of the display with a second point of the display.

17. The electronic device of claim 16 , wherein the segment includes a diagonal connecting a right part of the display with a left part of the display.

18. The electronic device of claim 1 , wherein the at least one processor is further configured to:
determine whether a screen movement direction corresponding to the user input is identical to a gate scan direction, and
detect the screen movement speed corresponding to the user input associated with the screen movement as the user input is received, when the screen movement direction is not identical to the gate scan direction.

19. A method of compensating for screen movement of a display of an electronic device, the method comprising:
receiving a user input associated with movement of a screen, the screen output on the display;
detecting a screen movement speed corresponding to the user input associated with the screen movement;
applying an amount of screen tilt compensation to the screen, the amount of screen tilt compensation determined according to an amount of change of the screen movement speed during a first range of the screen movement speed;
maintaining the amount of screen tilt compensation independent of a change of the screen movement speed during a second range of t
