When replacing the battery you would have disconnected the screen. When reassembling the device it is possible that you didn’t place the touch screen cable in properly. Make sure alll the connectors for the screen are placed correctly and see if that fixes your problem.
Does the display work? Can you actually see a picture or is the screen black? It's just not responding to touch?
