External smartphone Monitor using old laptop LCD display.

  Hi there, I am currently working on a project on reverse engineering. I wish to attempt at somehow using an old laptop lcd, as an external display for my smartphone. As an amateur electrician and computer programmer I would love it if someone could direct me and tell me which goals I have to accomplish to make that happen. I understand that the signals coming out of an lcd display are different then on a cell phone so I had found a control board that will transpose the signal into a VGA signal which can then be directed to a computer. But is there a way to send the signal to a usb port for a smartphone to plug into. Granted a program, software and drivers for the monitor ets would need to be created but that aside, could something like that be possible? Please indulge me. Thanks for your time.

Hello. Even I am trying to make such thing. But even I am not sure how to make it. What about using those lcd converters? Please tell me if you get some idea.
