The existing splicing methods are two, the first method is to directly splice by using an adhesive tape with a silica gel component, and the later stage of the part of the spliced adhesive tape needs to be cut, but huge waste is generated during cutting; in addition, the cut portion may damage the film when it is placed after winding, and an edge protection film has to be used in order to prevent the film from being pressed out of the mark when winding, which may result in an increase in cost. The second is a technique using laser splicing, but laser splicing equipment is expensive, and a special laser tape for the laser splicing equipment needs to be additionally purchased, so that the cost is high. There is therefore a need for improvements or optimizations to the existing splicing process of PET backplane to motherboard bonded films.
