You most likely blew the backlight circuit on the logic board. When you connect/disconnect the screen with the battery connected, it is possible to short the backlight circuit as the pins are adjacent within the connector. If you want to be certain, hine a bright flashlight on the screen when you connect it to an iTunes enabled computer. If you see a dim image, then the backlight circuit is blown.

Or try your original display to see if the problem remains.
The only way to fix this is to have the backlight circuit repaired and this requires a micro-soldering repair. This is not a typical DIY repair unless you already have the proper tools and experience as the component density on iPhone logic boards is very high.
