Although I think it's out-of-scope for what the class is teaching right now, I think the design choices companies make are usually quite interesting. Is there any reason behind the particular pixel layout in both phones? I believe red, blue, and green are used as pixel colors because they're the primary colors of light, but what determines the shade of color used for a pixel? In this image, it seems Apple uses a darker shade of red compared to Samsung's brighter shade; I wonder if there's an actual reason for it. Most phones also use OLED instead of LCD screens these days. Is there any difference in the pixel layout of an OLED that ends up being an advantage in displaying colors?
