Abstract

The invention relates to a flexible OLED (Organic Light-Emitting Diode) display device and a production method thereof. The flexible OLED display device comprises a flexible substrate, an obstructionlayer, a flattening layer, a display layer and a film packaging layer. The obstruction layer comprises a display area, first edge areas set at outer sides of the display area, and second edge areas set at the outer sides of the first edge areas. Lug bosses are set in the first edge areas. Grooves are set in the second edge areas. The flattening layer and the display layer are set on the display area. The film packaging layer covers the display area, the first edge areas and the second edge areas. The flexible OLED display device has good water and oxygen obstruction performance, and the service life of the display device can be improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a flexible OLED display device and a preparation method thereof. Background technique [0002] OLED (Organic Light-Emitting Diode, organic light-emitting diode) is an active light-emitting device, which has the advantages of high contrast, wide viewing angle, high luminous efficiency, rich colors, low-voltage DC drive, low power consumption, and fast response speed. OLEDs can be made into flexible organic electroluminescent devices after using flexible substrates. Compared with ordinary OLED displays, flexible OLED displays are thinner, more impact-resistant, can be bent and folded well, are easy to carry and can realize curved surface display. [0003] Flexible OLED displays need to maintain good performance during the bending process, and have high requirements for water and oxygen barrier properties. Because the metal materials used in OLED devices are relatively active, the...
