Abstract

The invention belongs to the technical field of OLED devices. The invention provides a flexible transparent OLED device structure and a preparation method thereof. The flexible transparent OLED devicestructure comprises a flexible transparent base material, a first transparent electrode arranged on the flexible transparent base material, an organic heterojunction film layer arranged on the firsttransparent electrode, an organic functional layer arranged on the organic heterojunction film layer, a second transparent electrode layer arranged on the organic functional layer, an organic antireflection film arranged on the second transparent electrode layer, a first extraction electrode connected with the first transparent electrode, and a second extraction electrode connected with the secondtransparent electrode. Therefore, under the condition that the device performance of the flexible transparent OLED device structure is ensured, the problems of high equipment requirements, high manufacturing cost and the like in the existing flexible transparent OLED device manufacturing process are solved.

Description

technical field [0001] The application belongs to the technical field of OLED devices, and in particular relates to a flexible transparent OLED device structure and a preparation method thereof. Background technique [0002] With the continuous advancement of science and technology, people's needs for light sources are becoming more and more diverse. OLED utilizes the light-emitting principle of ultra-thin organic layers, has many advantages such as ultra-light, ultra-thin, flexible, transparent, etc., and has broad application prospects in the field of lighting and display. [0003] However, most transparent OLED devices use ITO, silver nanowires, carbon nanotubes, graphene, ultra-thin metal films, and dielectric / metal / dielectric (DMD) structures of ultra-thin metal films as transparent electrodes. Because ITO contains the expensive and scarce element indium, and due to the inherent brittleness of oxide materials, it can no longer meet the application requirements of the c...
