Default [Q] Screen flickers after replacement

I dropped my Oppo Find 5 recently, and the screen was broken. Also the digitizer and touch screen was not responding anymore, so the phone was unusable. My brother bought a new screen on

So, everything was working perfect after the replacement, but the screen flickers on and off. Can I do something about this, or is the screen not capable for the Oppo Find 5? Interesting detail is that the screen doesn't flicker when I'm in Recovery Mode. Below is a video of the flickering:
