Screen light too bright
#2
(2020-01-07, 01:12 AM)syohana Wrote: I'm running a standard tiny pilot built by Sean. The lights on the Nokia screen are incredibly bright and ruin night vision for the watch keeper. I covered the screen with black tape up to the very edges of the display area and put red transparent plastic over it but it is still way too bright. Blindingly bright when you have been in the dark long enough to develop good night vision.

Ideally, is there any way to adjust brightness in software?

Or to add a knob to adjust it?

Failing that, is it practical to cut off the LEDs and replace them with dim, red ones?

Normally any kind of white light at night is forbidden on my boat, red light only. Adjustable, dimmable red light would be best. For effective use at night it needs to be really, really dim ,and all the light directed at the screen.

Has anyone come up with a solution or ideas for this? I'm reluctant to start cutting the LEDs off the display without knowing whether that will upset it somehow!
Just an idea:
Carefully disassemble the display, replace the blue LED's by red ones, carefully assemble the display again.
And put a small potentiometer in series with the backlight connection.

And let us know if it worked!
