Problems solved by technology

[0004] However, the brightness-enhancing film and the OLED device need to be bonded by an adhesive, so that the light emitted from the OLED device needs to pass through the interface between the OLED device and the adhesive, the adhesive and the brightness-enhancing film in sequence. The interface between, and the interface between the brightness enhancing film and the air; since the substances on both sides of each interface have different refractive indices, the light will be reflected and refracted when the outgoing light passes through the above interface, resulting in A certain degree of light loss; on this basis, a small amount of air will inevitably enter the adhesive to form tiny bubbles, which will cause the scattering of the outgoing light, thereby further aggravating the light loss

Abstract

The embodiment of the invention, which relates to the field of the organic light-emitting diode (OLED) technology, provides an organic light-emitting diode, an illuminating apparatus, and a display apparatus. On the basis of improvement of the light extraction rate of the OLED device, the number of interfaces which the emitted light passes through can be reduced, thereby reducing the light losses. The organic light-emitting diode comprises a substrate and a light-emitting structure carried by the substrate. The substrate arranged at a light extraction side of the light-emitting structure includes a substrate body and a micro structure that is arranged at the surface of the substrate body and is integrated with the substrate body. Application to the OLED device manufacture is realized.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an organic electroluminescent device, an illuminating device and a display device. Background technique [0002] Organic Light-Emitting Diode (OLED) has the advantages of energy saving, environmental protection, thinness, self-luminescence, long service life, etc., and has become a solid-state light source with great potential. [0003] Considering the luminous efficiency of the OLED device, in the prior art, a brightness enhancing film is usually attached to the light-emitting surface of the OLED device to achieve the effect of increasing the light-emitting rate. According to data, compared with OLED devices without brightness enhancement film, OLED devices with brightness enhancement film can increase the light extraction rate by more than two times. [0004] However, the brightness-enhancing film and the OLED device need to be bonded by an adhesive, so that the light emitted...
