It is recognized by the industry as the third generation of display technology after liquid crystal display (LCD). According to the driving method, OLED is divided into passive OLED (Passive Matrix OLED, PMOLED) and active OLED (Active Matrix OLED, AMOLED). PMOLED is also called passive matrix OLED, and AMOLED is also called active matrix OLED. To produce small-sized, low-resolution display panels, AMOLED can realize large-sized, high-resolution panels because it integrates a thin-film transistor (TFT) and a capacitor in each pixel and maintains the voltage by the capacitor. The focus of research and the development direction of display technology in the future.

However, the traditional RGB pixel arrangement structure is difficult to meet the high-resolution and high-brightness requirements of electronic devices for display screens. In the case of achieving the same resolution, there is another OLED pixel arrangement structure, which is realized by sharing sub-pixels. Arrangement, but the R/G/B ratio of the pixels formed by this arrangement is 1:1:2, which will affect the display effect of the display.
