Related researches have shown that doping an appropriate amount of small-sized transparent particles in the light penetrating film layer can improve light-emitting efficiency of the film layer. A micro lens technology currently under study is based on this theory. The current micro lens process is mainly realized by using ink jet printing (IJP) technology. However, materials commonly used in the IJP process contain polar functional groups such as a carbonyl group, so that a polarity of the ink is large. Therefore, if the micro lens process is printed on a surface of the film having a small water contact angle, the resulting micro lens film has low luminous efficiency.

The present disclosure provides an OLED display panel, which can solve a problem of low luminous efficiency of an existing OLED display panel.

In order to solve the above problem, the technical solution provided by the present disclosure is as follows:

The present disclosure provides an organic light emitting diode (OLED) display panel, including: a thin film transistor (TFT) array substrate; an OLED light-emitting layer disposed on the TFT array substrate; an encapsulation layer disposed over the OLED light-emitting layer; an inducing layer disposed on a light-emitting side of the OLED light-emitting layer; a micro lens array film disposed over the inducing layer; and an organic hydrophobic layer disposed between the inducing layer and the micro lens array film, where the organic hydrophobic layer is prepared by atomic layer deposition.

In at least one embodiment of the present disclosure, the OLED light-emitting layer comprises sub-pixels disposed on the TFT array substrate arranged in an array.
