Similar design is available at THIS SHOP  as very cheap board  

Basically it works as this one 3. LCD TFT as PC VGA monitor but is more comfortable to use, as it need only one 12V supply.
It have onboard 5V DC-DC converter for any externals.
Resolution changing is very easy by jumpers.

It works with the same 5 key keyboard, if need, is possible to solder on board DC socket and D-Sub socket.
Menu is very similar, board works with all inverters connected as BL, ADJ, Vcc, GND. 
LVDS output is also the same as other controllers, LVDS cables are interchangeable.  
Controller works great, as shown on picture below
