Thank you for the input. @dopamino to answer your questions. It's a very basic screen and my role in this project does not really have much to do with the connectivity aspect, just the screen UI interface. Sorry I can't give you more input on the technical stuff due to confidentiality. Every pixel is either on or off. No in-between. Here is a preview of the screen that is being used.
I started off using Sketch for this project but I'm learning that I will probably need to hand off designs in PSD using a pixel-fill method (like MS Paint) so I've modified the Photoshop pencil tool for that.
I actually have several concepts that I'd love to get a 5 sec preference test on for anyone who might be willing to take a peak. You can check them out here!
