I see the thing in an other way, the display intelligence in the mother board and the screen just receive print and graphic commands. The advantage is to have minimum intelligence in the screen, thus it works only as a terminal. Thus the smartphone application is really simple, it just receive and execute print command, and send X/Y of the display touch action. By the way, there is alway just one firmware to release. I work I is for a customer and for the same product it can propose different screen options, or use a PC application to act as interface.

I've got some of my ideas on a forum called Electro-Tech Online. sorry if I hijacked your thread.
No problem !! But difficult to answer without having the complete explanation about the problem
