Abstract
An organic light emitting diode (OLED) display panel includes a thin film transistor (TFT) array substrate; an OLED light-emitting layer; an encapsulation 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. By providing the organic hydrophobic layer with strong hydrophobic performance, a surface with a large water contact angle is provided for a subsequent formation of the micro lens array film, thereby improving an optical coupling ratio of the micro lens, and improving luminous efficiency of the OLED light emitting layer.
