The OLED display displays full-color pictures through three sub-pixels of red, green and blue, the three sub-pixels of red, green and blue are alternately and repeatedly arranged in a plane, adjacent three sub-pixels form a pixel unit capable of emitting any color, namely a basic image unit, and the pixel units are repeatedly arranged in the plane to form a display screen. The smaller the Pixel size, the higher the resolution or PPI (Pixel Per inc) of the display, the clearer and finer the displayed picture.
With the pursuit of higher and higher resolution of display devices, the pixel size is smaller, and the opening of a Metal Mask (FMM) for evaporating R, G, B light-emitting layer materials is smaller and smaller, but under the influence of the FMM manufacturing process, the size of the opening of the FMM is limited, and an OLED display with high resolution cannot be obtained.
