Description

[0001] 【Technical field】 [0002] The invention relates to the field of display manufacturing, in particular to a pixel structure of an OLED display panel and a manufacturing process thereof. [0003] 【Background technique】 [0004] Existing displays mainly include liquid crystal displays and OLED displays. [0005] Liquid crystal displays have many advantages such as thin body, power saving, and no radiation, and have been widely used. Most of the liquid crystal displays currently on the market are backlight liquid crystal displays, which include a liquid crystal panel and a backlight module (Backlight Module). The working principle of the liquid crystal panel is to place liquid crystal molecules between two parallel glass substrates, and apply a driving voltage on the two glass substrates to control the rotation direction of the liquid crystal molecules, so as to refract the light from the backlight module to produce a picture. [0006] Among them, Thin Film Transistor-Liqu...
