my ipod 5 screen flickers down the middle of my screen

i bought my ipod 5th gen back in december. it mostly sits in my car and charges off of my aftermarket cd player. occasionally when it dies ill take it inside and charge it on my wall charger. today it died and i plugged it inside for 2 hours and it would still not turn on. finally when i got it to turn on there is about a 1 inch wide bar flickering from the top to the bottom of the ipod. its not turning black or white its just flickering brighter to lighter. the ipod touch 5 doesnt have auto brightness so i dont know whats going on, please reply if you had this problem and fixed it.
