Abstract

The invention discloses a manufacturing method of an OLED device. The manufacturing method of the OLED device comprises the steps of carrying out microwave resonance water removal on one or multiple organic film layers in the OLED device in a vacuum environment; and carrying out selective heating rapidly on water molecules in the OLED device by adopting microwaves under a vacuum condition so as to remove the water molecules in the OLED device. The internal structures of substance molecules cannot be changed or the chemical bonds of the substance molecules cannot be destroyed in the water molecule removal process, so that the problem of decomposition of an organic material is avoided, and the service lifetime of the OLED device is prolonged efficiently.

Description

technical field [0001] This article relates to but not limited to the field of organic electroluminescent devices (OLEDs), especially a method for manufacturing OLED devices. Background technique [0002] AMOLED (or OLED, organic electroluminescent device) is rapidly expanding in the consumer electronics market due to its better display quality. With the maturity of OLED technology, the brightness, power consumption, color gamut, and color shift of OLED panels And other issues have been greatly improved, and the improvement of the life of OLED devices is still a relatively big challenge. The attenuation mechanism of OLED device life includes internal factors and external factors. Internal factors are mainly determined by the characteristics of the material itself. It is necessary to find more stable materials and better material combinations to improve device life; external factors mainly include environmental pollution. Migration of impurities, metal elements and residual ...
