I want to drive three separate 7" color LCD displays using an Android Tablet. The displays will be simple but dynamic. My intention is to use them to replace the instrument cluster on a vehicle. The android tablet will receive the vehicle sensor information (speed, rpm, temp, etc) via a USB Analog to Digital Converter. I'm not too concerned about writing this portion of the app for the vehicle. The part that I have no idea about is how to drive the multiple displays. Can an HDMI output be split by addressing it using a type of addressing? Can the LCD displays be driven as a USB device using a USB hub? Any suggestions?
