I see you can get a generic Pi LCD for $7.65, a 5" LCD with video in for $18.75, and a touchscreen Pi size kit for $19.90[1].
Going to the effort of breaking out DPI through the GPIO was quite creative. If optimized do you think these can hit sub $5? Either way, this was very clever. Thank you for taking the time to document this for others!
