Abstract

The invention provides a flexible OLED device and a preparation method thereof. Forming a light emitting layer on a flexible substrate; Vapor depositing a barrier material on the surface of the lightemitting layer, wherein the barrier material comprises a precursor, a photoinitiator and a crosslinking agent; During vapor deposition, a light beam is irradiated onto the surface of the barrier material to form a barrier layer for blocking water and oxygen on the surface of the light emitting layer. The flexible OLED device and the preparation method thereof can improve the production efficiencyand reduce the production cost.

Description

【Technical Field】 [0001] The invention relates to the field of display technology, in particular to a flexible OLED device and a preparation method thereof. 【Background technique】 [0002] Currently, organic light emitting diode (Organic Light Emitting Display, OLED) devices have the characteristics of low power consumption, high contrast, wide viewing angle, light and thin flexibility, etc., so they are widely used. The main application areas of OLED display technology include mobile phones, TVs, micro display devices, VR devices, vehicle display devices, etc. OLED display technology will replace TFT-LCD products and become the next-generation mainstream display technology. [0003] The most important performance indicators of OLED devices include luminous efficiency and device service life. At present, the improvement of the luminous efficiency of OLED devices mainly depends on the development of new functional materials and the optimization of the device structure. However, th...
