Problems solved by technology

These light-emitting materials and cathode materials are very sensitive to water vapor and oxygen. If water molecules and oxygen molecules continue to invade the OLED device, the organic layers (including hole injection layer, hole transport layer, light-emitting layer, electron transport layer, electron injection layer) will be damaged. is degraded, the cathode will be oxidized, thereby reducing the service life of the OLED device

Abstract

The invention belongs to the technical field of displaying, and provides an OLED displaying substrate, a manufacturing method for the OLED displaying substrate, and a displaying device. The OLED displaying substrate comprises an OLED device located on a substrate, and at least one packaging unit covering the OLED device, wherein each packaging unit comprises an inorganic layer, an organic layer, and a fluorine-doped diamond-like carbon layer located between the inorganic layer and the organic layer. The OLED displaying substrate, the manufacturing method for the OLED displaying substrate and the displaying device adopting the technical scheme have the advantages that the capability of the OLED displaying substrate in blocking external water and oxygen can be improved, so that the service life of the OLED displaying substrate is prolonged; and a sufficiently high light transmittance rate of the OLED displaying substrate can be guaranteed.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an OLED display substrate, a manufacturing method thereof, and a display device. Background technique [0002] Flexible OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode) is an important research direction of OLED devices. The luminescent material in OLED is generally high molecular polymer or small organic molecule compound, and the cathode material is generally metal material with low work function such as magnesium, aluminum, etc. These light-emitting materials and cathode materials are very sensitive to water vapor and oxygen. If water molecules and oxygen molecules continue to invade the OLED device, the organic layers (including hole injection layer, hole transport layer, light-emitting layer, electron transport layer, electron injection layer) will be damaged. If it is degraded, the cathode will be oxidized, thereby reducing the service life of the OLED de...
