[0002] With the development of display technology and people's needs, flexible display has become one of the more popular research projects in the display field. At present, the substrates of flexible display OLED display panels mostly use thin glass substrates, metal foil substrates or polymer substrates, etc. Among them, the flexibility and mechanical properties of glass are poor, so it is not suitable for use in flexible display panels; the roughness of metal foil substrates is relatively high, and the display device is easy to fall off when bent; polymer heat resistance and barrier properties are poor, so it is not suitable for use It is used in high-heat integrated circuits and affects the life of the device. Therefore, in summary, the performance of the substrate in the flexible OLED display panel in the prior art is poor, and the applicability to the flexible display panel is poor. Therefore, it is urgently needed now A flexible substrate suitable for flexible OLED display panels
