My 3.5" TFT LCD Screen doesn't turn on

Hello and warning for noob question. I just got my cheap 3.5" TFT LCD Screen and wanted to get it started. Plugged in a 11.1v 1480mAh battery but nothing happens.

Some more specs on the screen:
Screen size: 3.5"
Resolution: 320*240
Display format: 4:3
Power: ≤4W
Power supply: DC 12V
Video: 2 ways AV input reversing automatic display, AV signal automatic detection startup
System: PAL/NTSC 2 systems auto switch
Contrast: 350:1
Installation: install in the drive foreground

What could be wrong? Does it HAVE to be 12v input? As I understand it a 11.1v battery fully charged is more than 12v?
I haven't connected a video link yet, thought I would at least get the "No Signal" floating around or something.

You need to have a rx hooked up. Otherwise you'll get a black screen on some cheaper screens.
