Broken Screen HELP

[Max DeVos]

So a few weeks ago I dropped my phone and it cracked a small amount in the corner. Everything was fine. Recently, I dropped my phone in the snow, and it slowly stopped working. After giving it some time in rice, everything is functional, except the screen. It turns on and the screen actually boots, but just shows yellow lines (It is Sprint). The touchscreen works and it makes sound and plays the ringtone when I call it, the screen just doesn't work correctly.
I am looking at replacing it, but I am not sure if I need an LCD Digitizer or just the LCD screen. There is a difference of about $150, and I really don't want to purchase what I don't need.
