Abstract

The invention discloses an organic light-emitting diode display device and a manufacturing method. The organic light-emitting diode display device includes a substrate, a display functional layer and an encapsulation layer which are arranged in sequence. The encapsulation layer covers the display functional layer. The encapsulation layer comprises an inorganic encapsulation layer, an organic encapsulation layer and a fullerene structure, and the organic encapsulation layer is disposed on one side, remote from the substrate, of the inorganic encapsulation layer. The organic encapsulation layer comprises a lower surface adjacent to the side of the inorganic encapsulation layer, the fullerene structure is at least partially located on one side of the lower surface of the organic encapsulation layer. The fullerene structure includes fullerene and / or derivatives of fullerene. By embedding the fullerene structure directly into the organic encapsulation layer or sandwiched 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 total light reflection at the interface of the organic film and the inorganic film, and improving the luminous efficiency of the OLED device.

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...
