Problems solved by technology

[0005] During the above-mentioned OLED working process, the light-emitting layer will emit light in all directions. The light emitted upwards must pass through the cathode layer and the layers between the cathode layer and the light-emitting layer before it can be emitted. The light emitted downwards must pass through the anode layer and the light-emitting layer. Each layer between the layers, after being reflected by the anode layer, can be emitted through all the layers except the anode layer. It can be seen that the light emitted upwards and downwards must be refracted many times before it can be emitted. In the process of light propagation There will be energy loss every refraction, so the above structure will have a great impact on the luminous efficiency

Description

technical field [0001] The invention relates to the field of display technology, in particular to a light-emitting component, a preparation method thereof, and a display device. Background technique [0002] With the rapid development of display technology, there are more and more types of light-emitting components used in display devices. OLED (Organic Light-Emitting Diod, organic electroluminescent diode) is a very commonly used light-emitting component in display devices. Display devices with OLED light-emitting components are favored by people because of their advantages of thinness, lightness, low power consumption, wide viewing angle, and fast response speed. [0003] In the display panel of the display device, the OLED has a multi-layer structure, and each layer of the multi-layer structure can be an anode layer, a light-emitting layer, and a cathode layer in order from bottom to top (ie, from close to the substrate to far away from the substrate). In addition, in or...
