The invention discloses a flexible organic light emitting diode display panel, a display device and a fabrication method of the flexile organic light emitting diode display panel. The flexible organic light emitting diode display panel comprises a substrate, an organic light emitting device, a package thin film and at least retaining wall structures and also comprises an organic dielectric layer, wherein the substrate contains a display region and a non-display region, the organic light emitting device is arranged on the display region of the substrate, the package thin film covers the organic light emitting device and comprises an organic layer and at least one inorganic layer, the at least two retaining wall structures are arranged on the non-display region of the substrate, two adjacent retaining wall structures are arranged at intervals, the at least one part of retaining wall structures are covered by the package thin film, and the organic dielectric layer is arranged between the at least two adjacent retaining wall structures, is arranged on the substrate and is covered by the at least one inorganic layer. Since the inorganic layer and the organic dielectric layer are filled between the retaining wall structures, the stress generated by the inorganic layer during bending for many times can be effectively absorbed by the organic dielectric layer, and a crack is prevented from being generated between the retaining wall structures.
Description
technical field [0001] The invention relates to the field of display technology, in particular to a flexible organic light emitting diode display panel, a display device and a manufacturing method thereof. Background technique [0002] OLED flexible display devices are made on flexible substrates, and are deformable and bendable display devices. They have the advantages of low power consumption, small size, and deformability, and can be applied in a wider range of fields. However, the OLED flexible display device is prone to cracks at the edge of the panel during the bending process. [0003] The OLED flexible display device includes a display area on the substrate and a non-display area around the display area. The display area includes organic light-emitting devices formed on the substrate. In each organic light-emitting device, switching thin-film transistors, driving thin-film transistors, and storage capacitors can be formed. and an organic light emitting diode (OLED) ...
