Problems solved by technology

[0003] However, in the existing OLED display panel, due to the inorganic material layer, for example, the arrayed pixel circuit TFT used to drive the OLED pixels is formed of inorganic material, and the stress of the inorganic material layer is relatively large, so that during the bending process of the OLED display panel, Prone to breakage of the inorganic layer or peeling off of the OLED pixel functional layer
The above affects the reliability of OLED display panels

Abstract

The invention provides a display device, a flexible OLED display panel and a manufacturing method of the flexible OLED display panel. A wave-shaped organic soft layer is manufactured by utilizing an uneven structure of a plurality of strip-shaped sacrificial protrusions, then the strip-shaped sacrificial protrusions are removed, and an air gap is formed between the organic soft layer and a solid flexible substrate under the organic soft layer. The method has the advantages that 1, the tensile property of the organic soft layer is high relative to that of an inorganic material, so that the stress in the bending process of the OLED display panel can be buffered; 2, the organic soft layer is uneven, and compared with a planar structure, the stress in the OLED display panel with different curling degrees can be buffered; and 3, the air gap provides a containing space for the soft layer to stretch or compress the strain, so that stress transmission between the layers cannot be caused.

Description

technical field [0001] The invention relates to the technical field of OLED display equipment, in particular to a display device, a flexible OLED display panel and a manufacturing method thereof. Background technique [0002] With the development of display technology, bendable and flexible display devices based on flexible substrates have emerged. Among them, OLED has the advantages of low power consumption and good display brightness compared with other display devices due to its self-luminous characteristics. OLED displays prepared on flexible substrates are also easier to achieve bendable displays with smaller bending radii. Therefore, the fabrication of OLED display panels based on flexible substrates has attracted extensive attention. [0003] However, in the existing OLED display panel, due to the inorganic material layer, for example, the arrayed pixel circuit TFT used to drive the OLED pixel is formed of inorganic material, and the stress of the inorganic material...
