[0002] With the upgrading of product technology, the traditional connector connection method has been changed to ACF (anisotropic conductive film) attachment connection to solve the problems of large connector size and insufficient connection stability. However, in the ACF attachment bonding process, since the TFPC (screen touch flexible circuit board) is already connected to the panel (i.e. display panel module, Panel), and the MFPC (main control flexible circuit board, main substrate) has also completed the connection with the panel (Panel), when the TFPC needs to be bonded with the MFPC, the ACF must be attached to the MFPC first, which requires the TFPC to be folded first.

[0003] Therefore, further improvements are made to the above problems. Summary of the invention
