and displaying according to the target gray-scale value g2 of the pixel p to be processed so as to eliminate the phenomenon that the display device 200 appears jaggy at the arc-shaped boundary 201 when displaying an image, and improve the display quality of the display device 200.
Specifically, the first perpendicular line 2011, the second perpendicular line 2012 and the second curve 2031 enclose to form a first pixel region to be processed; the first perpendicular line 2011, the second perpendicular line 2012, the first curve 2021 and the second curve 2031 enclose to form a second pixel region to be processed; the first curve 2021, the first tangent line 201c, and the second tangent line 201d enclose to form a third to-be-processed pixel region. And judging the area where the pixel p to be processed is positioned by utilizing the position of the pixel p to be processed, thereby obtaining the gray scale coefficient ra of the pixel p to be processed corresponding to different areas.
Specifically, the position of the pixel p to be processed is determined by ellipse definition (the major axis of an ellipse in the ellipse is equal to the sum of the distances from a point on the ellipse to two focuses), that is, the pixel p to be processed is located on a certain ellipse with the focus F of the first ellipse 202 as the focus; the focus F of the first ellipse 202 comprises a first focus F1 and a second focus F2, the gray scale of the pixel p to be processed being determined according to the distance d of the pixel p to be processed from the focus F, the distance d of the pixel p to be processed from the focus F being equal to half of the sum of the distances of the pixel p to be processed to the first focus F1 and the second focus F2;
namely:

namely: if it is
Then: ra is 1; g 2-g 1;
if the half of the sum of the distances from the pixel p to be processed to the first focus F1 and the second focus F2 is greater than the length a2 of the major axis of the second ellipse 203 and less than or equal to the length a1 of the major axis of the first ellipse 202, the pixel p to be processed is located in the second pixel area to be processed, and the gamma ra of the pixel p to be processed is the ratio of the distance from the pixel p to be processed to the second ellipse 203 to the distance from the first ellipse 202 to the second ellipse 202; specifically, the gamma factor ra of the pixel p to be processed is equal to the difference between the length a2 of the major axis of the second ellipse 203 and the distance d of the pixel p to be processed from the focus, compared with the difference between the length a1 of the major axis of the first ellipse 202 and the length a2 of the major axis of the second ellipse 203;
namely: if it is
Then:
g2＝ra×g1。
if half of the sum of the distances from the pixel p to be processed to the first focus F1 and the second focus F2 is greater than the length a1 of the major axis of the first ellipse 202, the pixel p to be processed is located in the third pixel area to be processed, the gamma of the pixel p to be processed is 0, and the pixel p to be processed does not participate in the display;
