Abstract

The invention discloses a self-luminous device, which comprises a first electrode layer, a second electrode layer, a luminous layer and an insulating layer, wherein the luminous layer is arranged between the first electrode layer and the second electrode layer; the insulating layer is arranged between the first electrode layer and the second electrode layer or outside the first electrode layer and the second electrode layer; at least one layer body in the insulating layer, the first electrode layer and the second electrode layer generates a high refractive index material and low refractive index material mixing structure through a temperature change and / or a pressure change, so that the luminous efficiency is improved. The invention further discloses a preparation method of the self-luminous device and a display device. According to the self-luminous device, the light emitted from the luminous layer can be refracted and / or scattered when passing through the high refractive index material and low refractive index material mixing structure; the light totally reflected on the interface is reduced; and the light transmittance is improved, so that the light extraction efficiency of the self-luminous device is effectively improved; meanwhile, processing and production are carried out by the temperature change and / or the pressure change; the production cost is low; and the self-luminous device is suitable for mass production.

Description

technical field [0001] The invention relates to the technical field of organic luminescence, in particular to a self-luminous device, a preparation method and a display device. Background technique [0002] Organic Light-Emitting Diode (OLED) display has become a new generation of display technology, because it can emit light by itself, without backlight, and has simple structure, ultra-thin, fast response, wide viewing angle, low The characteristics of power consumption and the ability to realize flexible display lights, coupled with the fact that the investment in its production equipment is much smaller than that of liquid crystal displays (Liquid Crystal Display, LCD), gradually become the main force of the third-generation display devices in the field of display technology. [0003] Although organic light-emitting diodes have many advantages, they also have their own shortcomings, one of which is the low utilization rate of photons. The light emitted by the light-emitt...
