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 (organic light emitting diode) display panel and a method for manufacturing the same. The display device, the flexible OLED display panel and the method have the advantages that semi-solidified flexible organic material layers are arranged on the lower surface of a completely solidified flexible organic material layer, the elastic modulus ofthe semi-solidified flexible organic material layers is lower than the elastic modulus of the completely solidified flexible organic material layer, in other words, stress, which corresponds to unitstrain, of the semi-solidified flexible organic material layers is lower than stress of the completely solidified flexible organic material layer under the condition of unidirectional stress, accordingly, buffer of the completely solidified flexible organic material layer on stress generated by inorganic material layers on the completely solidified flexible organic material layer during bending can be improved by the aid of the semi-solidified flexible organic material layers, breakage of inorganic layers and stripping of OLED pixel functional layers can be prevented, and the bending performance of the flexible OLED display panel can be improved.

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...
