Then you will need to read the LCD from the board convert it to something like RS-485.
The second board will then Receive the RS-485 and Drive the Second display.
The LCD signals will not travel 20 meters.

      Can be hard to be fast enough            01/01/70 00:00      
   Shouldn't be a problem            01/01/70 00:00      
      some HW might be needed            01/01/70 00:00      
         Monitor the LCD databus then send via 485            01/01/70 00:00
