Screen broken. Glass intact, but the pixels don't
Hi. Today, my iPhone 5 fell out of my pocket. I quickly checked to see if the screen and shattered, and luckily it hadn't. However, the top half of the screen turns different colors (mostly blue) and on the right side of the screen theres a black circle. Sometimes i can type and use the phone normally (discoloration still there), but sometimes the phone thinks i'm typing when i'm not, resulting in random gibberish being texted to my friends. I've seen people replace their iPhone 5 with an "LCD Digitizer" or something like that, and was wondering if this is what I need. Thanks!
