When the electronic device 10 according to the comparative example outputs image data (eg, image data in which an area beyond a specified range is white and/or image data in which an edge area is white) through the display 13, the display 13 A boundary line having a specific color may be output between the bezels 12t and 12b or the edge portion of the display 13 . For example, red subpixels and blue subpixels may be disposed in one or more pixel lines of the display 13 adjacent to the upper bezel 12t. Therefore, when image data with white edges and/or image data with white edges are to be output, the red sub-pixels and the blue sub-pixels may be turned on. Since the edge is composed of only red subpixels and blue subpixels, the boundary line 15a of a specific color (eg, purple) may be viewed along the upper bezel 12t.

As another example, green sub-pixels may be disposed in one or more pixel lines of the display 13 adjacent to the lower bezel 12b. Accordingly, the green sub-pixels may be turned on to output image data having a white area and/or image data having a white edge over a specified range. Since the edge is formed of only green sub-pixels, a green boundary line 15b may be output along the lower bezel 12b. The purple boundary line 15a and the green boundary line 15b may distort image quality of the display 13 and reduce visibility of the display 13 . In this document, the purple boundary line 15a and the green boundary line 15b are exemplary, and other color boundary lines may be viewed along the bezels 12t and 12b of the display 13 .

The OPR value may mean an average value of grayscales of pixels (or sub-pixels) in an on state among pixels disposed on the display panel 131 . For example, if the OPR value is high, since the number of pixels in the on state is large, bright image data can be output. Conversely, if the OPR value is low, dark image data may be output because the number of on-state pixels is small.

In operation 403, the electronic device 100 may compare the OPR value calculated in operation 401 with a designated value (eg, 10%). If the OPR value calculated in operation 401 is equal to or greater than the specified value, operation 405 may be performed, and if the OPR value calculated in operation 401 is less than the specified value, operation 407 may be performed.

In operation 407 , the electronic device 100 may maintain the brightness of subpixels disposed adjacent to the edge of the display panel 131 . Alternatively, in operation 407 , the electronic device 100 may not reduce the brightness of subpixels disposed adjacent to the edge of the display panel 131 . For example, when an image in which most of the area is black and the edge area is white is output (or when the OPR value is less than a specified value), the electronic device 100 displays sub-pixels disposed adjacent to the edge of the display panel 131. brightness can be maintained. According to an embodiment of the present invention, the display 130 maintains the brightness of sub-pixels disposed adjacent to the edge of the display panel 131 even when an image in which most of the area is black and the edge area is white is output. It is possible to prevent the image quality from being distorted.

According to an embodiment, the electronic device 100 may reduce the brightness of subpixels disposed adjacent to the edge of the display panel 131 based on eye tracking. For example, a purple boundary line 15a or a green boundary line 15b may be viewed according to an angle at which the user gazes at the edge of the display panel 131 . The electronic device 100 displays a first line 310-1, an m-th line 320m, an i-th line 330, and/or a ii-th line based on the angle at which the user gazes at the edge of the display panel 131. The brightness of the red sub-pixels R, the blue sub-pixels B, and the green sub-pixels G disposed on the line 340 may be reduced.

According to an embodiment, when an image having a white edge is output, the electronic device 100 may reduce the brightness of subpixels corresponding to the white edge. For example, when an image having a white edge is output in the central area of the display panel 131, the electronic device 100 may reduce the brightness of subpixels corresponding to the white edge.

5 illustrates image data according to an exemplary embodiment. FIG. 5 is a diagram for explaining operation 407 shown in FIG. 4 in detail.

The image data 500 illustrated in FIG. 5 may include a first area 511 and a second area 512 surrounding the first area 511 . The first area 511 may have a black or dark color, and the second area 512 may have a white or bright color. Since the area of the first region 511 is relatively larger than that of the second region 512 , the OPR value (eg, less than 1%) of the image data 500 may be low.

According to an embodiment, the electronic device 100 does not maintain or reduce the brightness of sub-pixels disposed adjacent to the edge of the display panel 131 when image data 500 as shown in FIG. 5 is output. may not be According to an embodiment of the present invention, even when image data 500 as in the example shown in FIG. 5 is output, by maintaining or not reducing the brightness of subpixels disposed adjacent to the edge of the display panel 131, It is possible to prevent the image quality of the display 130 from being distorted.
