Example Embodiment
[0036] The exemplary embodiments of the present invention are described below with reference to the drawings. It should be understood that these specific descriptions are only used to teach those skilled in the art how to implement the present invention, not to exhaust all possible ways of the present invention, nor to limit the scope of the present invention.
[0037] Such as figure 1 with figure 2 As shown, the present disclosure provides a transfer method based on liquid capillary force and surface tension, which uses the transfer head 1 to separate the thin film device 2 from the original substrate. In a specific embodiment, the transfer method includes the following steps:
[0038] Thin film device 2 preparation steps: forming thin film device 2 on the original substrate.
[0039] Liquid film 3 formation step: apply liquid on the transfer surface of the transfer head 1. The liquid can form a liquid film 3 between the transfer surface of the transfer head 1 and the thin film de...
