I am looking to design something similar to Garmin's HUD for cars and am having a hard time finding suitable displays.
The display must be bright even in full daylight operation, which is why Garmin used a VFD display in their product that produces about 7,500 nits.
I cannot seem to find anything on the market either LCD, LED, or VFD that would produce such a bright image.
About the closest thing I could find to what I am looking for is Adafruit's 128x64 graphic VFD display. It's an ideal size, but unfortunately is still not bright enough.
Another option I considered was dismantling an LCD display and adding my own powerful backlight, exactly as is done in the following tutorial: Projection Clock
It seems that most LCD displays compatible with Arduino are sold on shields which would prevent me from doing something similar.
The last option I considered was buying a pico projector, but it is more costly and would require HDMI/VGA interfacing with an Arduino.
Would anyone have other suggestions for a powerful display?
