Abstract
A manufacture method for a projection capacitive touch screen, includes following steps: (1) placing a clean PET substrate on a 3D printing platform, (2) the 3D printing platform outputting movement of x, y and z directions through control software, (3) aligning tail-throwing leads on the PET-X film, (4) tearing off the protective release film on one side of the PET-Y film, (5) bonding the PET-Y film and the PET-X film, (6) cutting off the redundant areas around the PET-XY film completed in the step (5), (7) drying the PET-XY film, and (8) laser welding the dried PET-XY film to obtain a projection capacitive touch screen.
