Out of curiosity, what screen are you using?

I will try an automated auto dim circuit based on the ambient light, i use LM317, which is a variable output voltage regulator.50 LEDs ( 3.5v - 3A ), it is reasonably readable in direct sunlight.It must be equivalent to 600+Nits, i think .If you add all 3M films , the final outcome is awesome!
The screen is Eby 701 7''.
