The P array of AMOLED: the struggle between display effects and lifespan. When it comes to the downsides of AMOLED, the first thing that comes to mind is the P array, namely the Pentile array. Samsung was the first company to massively produce OLED panels and to use P array. The Galaxy S4 first use the P array called Diamond Pixel, which head down a different path with the standard RGB alignment.
Simply speaking, RGB type equally arranges the sub-pixels of the three original color of red, green and blue, while the sub-pixels of RGB will not be equally arranged in P array, and it shares the pixels, so the actual pixel density of P array is lower than that of RGB. Which leads to the fact that even with the same resolution, P array are not as clear as RGB, so it is often called "big fruit variant screen".
