[0002] Organic light-emitting diode display (OLED) is a device that uses a multi-layer organic thin film structure to generate electroluminescence, which not only has a simple manufacturing process but also has a relatively low driving voltage, and these characteristics make OLED's superiority in flat display technology very prominent. In addition, compared with liquid crystal display (LCD), OLED has other characteristics such as lighter and thinner, higher brightness, lower power consumption, faster response, higher resolution, excellent flexibility, and high luminous efficiency, which can meet the new consumer needs for display technology. Therefore, OLED display has become the focus of development for all display manufacturers.

[0003] The pixel structure of an OLED display has an important effect on its display effect. The pixel structure of real sub-pixels refers to each pixel unit containing a red sub-pixel (R), a green sub-pixel (G) and a blue sub-pixel (B) that are independent of each other. This pixel structure has a relatively low aperture ratio of the mask used in the manufacturing process, which makes it difficult to meet the current needs for high pixel density display. The pixel structure of combined sub-pixels combines a red sub-pixel (R) with a green sub-pixel (G) and combines a green sub-pixel (G) with a blue sub-pixel (B) to form a pixel unit. This pixel structure can improve the aperture ratio of the mask, but its display effect is relatively poor. Summary of the Invention [Problem to be solved by the invention]
