In some embodiments, also as illustrated in FIG. 4, the OLED screen 400 of this embodiment is a flexible OLED screen. The flexible OLED screen includes a glass cover 410 and a display panel 430 connected by an optical glue layer 420. The OLED screen 400 also includes an auxiliary material 440 at a side of the display panel 430 away from the glass cover 410. That is, from top to bottom, the OLED screen 400 includes the glass cover 410, the optical glue layer 420, the display panel 430, and the auxiliary material 440 in turn. The display panel 430 includes a flexible substrate 431 and the flexible substrate 431 is a polyimide film, that is, a PI film. An upper surface of the flexible substrate 431 is coated with an organic light emitting layer 432 and encapsulated by tetrafluoroethylene (TFE).
