Would the digitizer work without an LCD screen attached?

Kid broke the glass screen on my ipad 4. ALL was working, just the cracked screen was an eyesore so I ordered a new glass digitizer from ebay. I ended up breaking the connection on the logic board for the LCD screen before realizing the geniuses at apple (who can do no wrong) made these connectors backwards from every other computer. Anyhow, I am going to send in the logic board for repair and wanted to completely erase everything on it, only now I cannot connect my lcd to see. I tried connecting to iTunes on my computer with the ipad connected, and the computer tells me to confirm ON THE IPAD that I want to connect to the ipad. SO, I connect my new digitizer screen to the ipad WITHOUT the LCD screen in place and start tapping all over the screen hoping I can hit the "yes" to confirm connection to my pc but it doesn't seem to work. I am now wondering if the LCD needs to be attached in order for the digitizer to work? I cannot connect my LCD since my connector is bad. My ipad does indeed get recognized by my computer, but I cannot seem to get the digitizer to work. I touched every fingerwidth all up and down and everywhere to no avail. The digitizer connection appears perfect. Straight line right at the connector. Does anyone know if the digitizer should work without the LCD? I don't know if I got a defective digitizer from ebay. Thanks in advance.
