Abstract: The present invention provides a method of assembling an LCD panel, an interface apparatus, and an assembling apparatus. In this invention, the first panel of the LCD panel is mounted on the interface apparatus before being pressed to the second panel of the LCD panel. Therefore, the complexity of the assembly room can be simplified and the cycle time in the assembly room can be shortened by moving the processes of flatly attaching and separating panels out of the assembly room. The interface apparatus is easier to be processed than a glass substrate during operation. The design of the interface apparatus can simplify the mechanisms in the assembly room and shorten the cycle time. The usage of the interface apparatus can reduce the alignment error caused by nonsynchronization of releasing static electricity suckers.
