How to backup my Iphone when the screen is not working? - 1

The LCD of my Iphone is not working because I dropped it in water, IIm not willing to bring it to the shop since I've already spent $250+ on fixing it before, so now I want to get all the data in it backed up but I can't unlock it, is there another way?

Added (1). But is it really an LCD problem? The touch screen won't work and there are lines on the screen.

Added (2). lines being digital and not the whole black kinds
