Method to improve display performance at edges of circular display screen

A method for improving display performance at edges of a circular display screen, comprising:

• determining an edge area and a central area of the circular display screen, the edge area surrouding the central area;
• along a direction from a geometric center of the circular display screen to the edge area of the circular display screen, dividing the edge area into n display regions each having a different luminance-level, where n is 15;
• and
• according to luminance of pixels in the central area and the luminance-level of each of the n display regions, adjusting luminance of pixels in each of the n display regions to corresponding target luminance,
• wherein the pixels in each of the n display regions have different corresponding target luminance,
• the pixels in a same display region have same corresponding target luminance,
• along the direction from the geometric center to the edge area of the circular display screen, the corresponding target luminance of the pixels in the n display regions sequentially decreases, and
• along the direction from the geometric center of the circular display screen to the edge area of the circular display screen, ratios between the corresponding target luminance of the pixels in the n display regions and the luminance of the pixels in the central area is sequentially configured to be approximately 0.9, 0.8, 0.6, 0.5, 0.4, 0.3, 0.2, 0.1, 0.08, 0.06, 0.04, 0.03, 0.02, and 0.01.
