A 403ppi (pixel per inch) real RGB AMOLED was fabricated without using Fine Metal Mask (FMM). Organic light‐emitting layer material was printed on array panel, resulting in a novel process with low cost and high pixel density. The OLED materials printed uniformly and the OLED device performed good property. The profile of the pixel was designed as a hexagonal pattern. Based on this design, it is possible to achieve 403 ppi real AMOLED using pixel printing process. The image quality for this hexagonal pixel arrangement was evaluated by a bmp format Pixel Layout Simulation picture.
