Dead Pixels on IPhone 4 screen?

A couple months ago my phone became really splotchy, had horizontal lines across the entire screen, and the picture would stay after changing apps. Today a black splotch showed at the top left and a green line running down the side. I think the black is dead pixels but I'm not sure. Is there a way to fix this at home without replacing the screen or getting a new phone?
