Display apparatus and control method thereof

1. A display apparatus, comprising:

a display panel configured to drive a frame of a first resolution at a first frame rate, the display panel comprising gate lines each connected to pixels in a row of the display panel and data lines each connected to pixels in a column of the display panel;

a communication interface comprising circuitry configured to receive content; and

a processor configured to:

identify a frame rate of the received content,

identify, based on additional information of the received content or image analysis of the received content, whether the received content is upscaled content upscaled from an original resolution to an upscaled resolution, and

based on the frame rate of the received content being greater than the first frame rate and the received content being identified as upscaled content, control the display panel to display the received content at a second resolution, lower than the first resolution, and at a second frame rate, greater than the first frame rate, by reducing a resolution of the received content to the second resolution,

wherein the processor is configured to control the display panel to display the content of the second resolution by concurrently driving two or more gate lines of the plurality of gate lines for displaying one pixel line in a frame of the content of the second resolution.

2. The display apparatus of claim 1 , wherein the processor is configured to repeatedly display one pixel line of the content of the second resolution by driving two or more adjacent gate lines of the plurality of gate lines.

3. The display apparatus of claim 1 , wherein the display panel is configured to display one frame for a first time period corresponding to the first frame rate, and

wherein the processor is configured to control the display panel to display one frame of content of the second resolution for a second time period, the second time period being less than the first time period and corresponding to the second frame rate.

4. The display apparatus of claim 1 , wherein the processor is configured to adjust the received content to the second resolution based on an equal value of a vertical resolution of the display panel.

5. The display apparatus of claim 4 , wherein the processor is configured to adjust a horizontal resolution of the received content based on a horizontal resolution of the display panel, and to adjust a vertical resolution of the received content based on the equal value of the vertical resolution of the display panel.

6. The display apparatus of claim 4 , wherein the processor is configured to identify the equal value of the vertical resolution of the display panel based on a frame rate of the received content and the first frame rate.

7. The display apparatus of claim 4 , wherein the first frame rate is a maximum frame rate which the display panel is capable of outputting, and

wherein the vertical resolution of the display panel is a number of pixels arranged in a vertical direction of a plurality of pixels of the display panel.

8. The display apparatus of claim 1 , wherein the processor is configured to:

based on the received content being a first type, adjust resolution of the received content to the second resolution, and

based on the received content being a second type, control the display panel to display the received content at the first frame rate without adjusting resolution of the received content.

9. The display apparatus of claim 1 , wherein the processor is configured to:

based on a frame rate of the received content being identical to the first frame rate, increase the frame rate of the received content by performing frame interpolation on the received content, and

reduce resolution of the frame-rate increased received content to the second resolution.

10. The display apparatus of claim 1 , wherein the processor is configured to, based on receiving a command to increase a frame rate being input, reduce resolution of the received content to the second resolution.

11. A method of controlling a display panel configured to drive a frame of a first resolution at a first frame rate and comprising gate lines each connected to pixels in a row of the display panel and data lines each connected to pixels in a column of the display panel, the method comprising:

receiving content;

identify a frame rate of the received content;

identify, based on additional information of the received content or image analysis of the received content, whether the received content is upscaled content upscaled from an original resolution to an upscaled resolution, and

based on the frame rate of the received content being greater than the first frame rate and the received content being identified as upscaled content displaying the received content at a second resolution, lower than the first resolution, and at a second frame rate, greater than the first frame rate, by reducing a resolution of the received content to the second resolution,

wherein the displaying of the content of the second resolution comprises concurrently driving two or more gate lines of the plurality of gate lines for displaying one pixel line in a frame of the content of the second resolution.

12. The method of claim 11 , wherein the displaying comprises repeatedly displaying one pixel line of a content of the second resolution by driving two or more adjacent gate lines of the plurality of gate lines.

13. The method of claim 11 , wherein the display panel is configured to display a one frame for a first time period corresponding to the first frame rate, and

wherein the displaying comprises displaying one frame of content of the second resolution for a second time period, the second time period being less than the first time period and corresponding to the second frame rate.

14. The method of claim 11 , wherein the adjusting comprises adjusting the received content to the second resolution based on an equal value of a vertical resolution of the display panel.

15. The method of claim 14 , wherein the adjusting comprises adjusting a horizontal resolution of the received content based on a horizontal resolution of the display panel, and adjusting a vertical resolution of the received content based on the equal value of the vertical resolution of the display panel.

16. The method of claim 14 , further comprising:

identifying the equal value of the vertical resolution of the display panel based on a frame rate of the received content and the first frame rate.

17. The method of claim 14 , wherein the first frame rate is a maximum frame rate, which the display panel is capable of outputting, and

wherein a vertical resolution of the display panel is a number of pixels arranged in a vertical direction of a plurality of pixels of the display panel.

18. The method of claim 11 , further comprising:

based on the received content being a first type, adjusting resolution of the received content to the second resolution and displaying at the second frame rate, and

based on the received being a second type, displaying the received content at the first frame rate without adjusting resolution of the received content.
