Might be a bit hard to see in this line drawing but on the RHS you can see an 'end on' view. The printed circuit board is on the left and the black plastic moulded frame on the right. I have added a lip around the edge so that, from the front, it will fill the existing area provided for by the game manufacturer without the need to add a foam trim.
Doing it this way also leaves space on the PCB for the driver IC's and other stuff - they fit under the lip. The overall height is 2MM lower than a glass DMD so that will allow room for a coloured filter that will fit over the entire front.......well, that's the plan at this stage anyway......
