Embodiment
The invention discloses a kind of manufacturing approach of touch display screen, it may further comprise the steps:
Step 1: adopt the gold-tinted making technology to prepare alignment mark (MARK) in the induction glass and the display screen glass of capacitive touch screen respectively;
Step 2: will show that IC is bundled in display screen glass, (FPC) is bundled in display screen glass with FPC, and it is on glass that FPC is bundled in induction;
Step 3: respectively display screen glass after binding and induction glass are carried out functional check and visual testing;
Step 4: between display screen glass through functional check and visual testing and induction glass, smear the optics viscose glue;
Step 5: display screen glass behind the gluing and induction glass are put into contraposition equipment, and wherein display screen glass is attracted on the worktable of contraposition equipment, smears facing up of optics viscose glue; Induction glass is attracted on the vacuum slot of worktable top, smears facing down of optics viscose glue; The camera of contraposition equipment absorbs the display screen glass alignment mark position on glass with induction respectively, and the controller of contraposition equipment calculates both position deviations, and controller moves check and correction according to result of calculation control direct motor drive display screen glass or induction glass;
Step 6: the display screen glass of accomplishing contraposition exerted pressure with induction glass makes it bonding;
Step 7: behind display screen glass and the induction bonding glass, coat bonded adhesives in induction four jiaos of surface on glass or four limits, at induction surperficial applying one deck cover on glass;
