Oznog:
I would really like to make the display stand out, and using an LCD gives me endless possibilities. At the disadvantage of using a separate VGA+ controller, of course.
As for the heat, for now I'll settle for a working prototype. The company tunedwolf suggested (Primeview) lists the operating temperature of some of its screens between -20 and +80 (degrees Celsius), which is more than enough for me.
I've looked into the controllers you've suggested, and I might actually use that as an early prototype (just to tune the sensor readings, etc.). Any recommendations on what display controller I should use for a 800x480 display?
