- the flexible substrate 1 can also be adjusted by the action of the magnetic field between the first magnetic unit and the second magnetic unit while the flexible substrate 1 is being stretched.
- a magnetic film material can be prepared in the spacer area of the flexible substrate 1 to form the first magnetic unit.
- the preparation of the magnetic film can be completed by inkjet printing and curing processes.
- the formation of the second magnetic unit and the assembly of the flexible substrate 1 and the supporting substrate 2 can be completed with reference to the above steps (steps S5 and S6), which will not be repeated here.
- the display panel prepared by the manufacturing method provided in this embodiment is provided with a first magnetic unit and a second magnetic unit.
- the flexible substrate 1 is attached to the supporting substrate 2 to avoid distortion of the display area of the flexible substrate 1, thereby
- the flexible substrate 1 of each display area is fixed within a certain range, so as to ensure that the display panel has a good display effect.
- This embodiment provides a display device, including any one of the display panels provided in FIG. 1 or 2.
- the display device may be an OLED display device, such as a mobile phone, a tablet computer, a television, a monitor, a notebook computer, a digital photo frame, a navigator, and any other product or component with a display function.
- OLED display device such as a mobile phone, a tablet computer, a television, a monitor, a notebook computer, a digital photo frame, a navigator, and any other product or component with a display function.
