These images show the screen of a Microsoft Surface Duo smartphone. Unlike many other designs, this screen uses an asymmetric distribution of color. Clearly, green appears much more frequently than blue and red in a repeating unit. This is a deliberate arrangement. The human eye is slightly more sensitive to green. By repeating this color more often, a screen can appear brighter. This higher apparent brightness allows a lower actual brightness for the screen, saving precious battery life. While green is placed as rectangles in the pattern, blue and red appear as dots. However, a closer inspection of these dots shows that they are, in fact, octagons. This may be related to a simplification of the micro-scale manufacturing processes involved.
