My iPad 3 Lcd does not work after I snapped it in half

Ok, ok, I know it seems like a stupid question, but hear me out. So I bought an iPad 3 with a shattered digitizer but otherwise good lcd off of eBay. It wasn't ic locked, yay! So I set away at repairing it. However, the digitizer was broken into many pieces, and when I went to lift the LCD out of the iPad, some pieces of still-stuck digitizer pressured it and it got a diagonal crack. At this point half of the LCD still worked. Later on I plugged the iPad back on and the LCD gave no signs of life. iTunes doesn't work because it has a passocde either. Should I just get a new LCD or is the problem something else entirely?
