I've managed to scratch my Curve 8900's screen. If I purchase full housing will that solve my problem or is the screen that is on the phone when its assembled the actually LCD?

I need to know this as I have some OEM housing on the way hoping to just replace it but on the disassembly video when the case is removed it seems like the screen area is hollow, which leads me to believe that the screen is non removable, that I need an entirely new LCD.

I need some help asap so I can cancel the order if need be. Thanks in advance.
