Yup! If this works, it should go, if it looks decent enough, it isn't anything bad considering it also should be able to do pretty fine from the battery (six hours is something!).
Out of curiosity I did a bit of research after the solution. It is hard to make out on the site, but it is an AMT630A, I found a datasheet
here. Arkmicro technologies, checked their site, got an error clicking on their LCD display processor: "Error: Access denied for user 'joe'@'localhost' (using password: YES)", oh well, chinese stuff, somebody couldn't even manage to set up a MySQL database proper... Joe? JOE?!! Where are you?
Anyway, I was curious of the chip's capabilities. An interesting oddity is that it even has a 8052 incorporated, possibly it controls OSD, and maybe some configuration, it doesn't reveal from the datasheet what exactly. A bit difficult to make it out, but the 8 pin chip on the right seems to be an SPI flash (the few visible traces correspond to typical SPI flash pinout), combined with the Application diagram on the datasheet, I could imagine it contained code for the MCU... Let's poke around a bit for this... And voilà:

So somebody even took the time already to disassemble this thing, and come up with an own firmware for it!
No RGB input anywhere, though, but the solution in overall is interesting
