A sub-pixel region may correspond to a plurality of micro lenses. The micro lens is spherical. The micro lens 15 is formed by an ink jet printing method. Generally, the material used in the micro lens manufactured by ink jet printing has a large polarity. It is necessary to print on the surface of the film with a large water contact angle to prepare a micro lens with good performance. The surface of the organic hydrophobic layer 14 has strong hydrophobicity, and the surface has a large water contact angle, which is favorable for printing the micro lens material on the surface thereof. The printed ink droplets are cured to form micro lenses distributed in an array.

The encapsulation layer 16 is disposed on the surface of the micro lens array film 15. The encapsulation layer 16 covers the OLED light-emitting layer 12. The encapsulation layer is used to prevent water and oxygen from corroding the OLED device. The encapsulation layer may form a multi-layer package structure by disposing an organic layer and an inorganic layer layer-by-layer.

In other embodiments, the OLED light-emitting layer can be a bottom light emitting structure. The inducing layer is disposed between the OLED light-emitting layer and the TFT array substrate. Specifically, the inducing layer is disposed on the TFT array substrate. The organic hydrophobic layer is disposed on a side of the inducing layer facing away from the TFT array substrate. The micro lens film is disposed on a side surface of the organic hydrophobic layer facing away from the TFT array substrate.

As shown in FIG. 2 to FIG. 6, the present disclosure further provides a manufacturing method of an OLED display panel according to the first embodiment, which includes:
