Why my touch screen has malfunction?

Hi! Somehow the adhesive release my LCD screen a bit and I can lift it on the bottom about 1 mm. I have no problem with it, but after this, the touch screen started to mailfunctioning. There is a specific area on the screen, where not always gets my inputs and also sometimes gets inputs even I haven't touched it. Would a screen replace solve my problem, or can this problem comes from another cause? Thanks!
