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 thereof, wherein a concave-convex undulating organic soft layer is fabricated by utilizing an uneven structure of a plurality of first deep grooves in a solid flexible substrate, and an air gap is formed between the organic soft layer and an inorganic material layer on the organic soft layer. The invention has the advantages that: firstly, a plurality of first deep grooves are made to remove part of the material of the solid flexible substrate, and the bending performance of the solid flexible substrate is improved; Secondly, the tensile property of the organic soft layer is better than that of the inorganic material, which can cushion the stress in the bending process of the OLED display panel. Third, the air gap provides the accommodation space for tensile or compressive strain of the soft material layer, and does not cause the stress transfer between the layers.

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...
