Abstract

The invention discloses an organic light emitting diode display device and a manufacturing method thereof. The organic light emitting diode display device comprises: a base substrate, a display function layer and an encapsulation layer arranged in sequence, the encapsulation layer covering the display function layer; the encapsulation The layers include an inorganic encapsulation layer, an organic encapsulation layer and a fullerene structure, the organic encapsulation layer is arranged on the side of the inorganic encapsulation layer away from the base substrate; the organic encapsulation layer includes a The lower surface of the side, the fullerene structure is at least partially located on one side of the lower surface of the organic encapsulation layer; wherein the fullerene structure includes fullerene and / or fullerene derivatives . By embedding the fullerene structure directly into the organic encapsulation layer or sandwiching it between the inorganic encapsulation layer and the organic encapsulation layer, the refractive index difference between the organic film and the inorganic film is reduced, thereby reducing the light intensity at the interface between the two. Total reflection improves the light extraction efficiency of OLED devices.

Description

technical field [0001] The present invention relates to the technical field of semiconductors, and more specifically, to an organic light emitting diode display device and a manufacturing method. Background technique [0002] Organic light-emitting diode (OLED) is a brand-new display technology, using organic semiconductor materials as functional materials, driven by an electric field, and recombined to emit light through carrier injection. Because of its remarkable advantages in flat panel display, such as high luminance, rich colors, low-voltage DC drive, simple preparation process, high efficiency, energy saving, and environmental protection, it has increasingly become a hot spot in international research. [0003] Flexible display is a major development direction of display technology, so OLEDs are often prepared on flexible substrates, but flexible substrates are weaker in blocking water and oxygen than glass substrates. In order to prolong the service life of flexible...
