What you could do is just use the Carousel module to switch screens or use MMM-Scheduler to get what you want or a combination of both :)
I use scheduler because depending on what time of day I have different things displayed and at night it turns completely off so it doesn’t keep me awake.

@cowboysdude have you got any ideas on how I block the blacklight so it could be kept it on at night? I’m thinking about using a variant of 1 way glass but would love your opinion.
-
@cowboysdude I know this is like 7 months later, but my parts only just arrived. Do you have any ideas on ways to block the backlight? a mirror order isn’t exactly possible with the cost, I was thinking maybe blockout blinds or some kind of privacy glass layer?
-
I’d think there should be a way to control the dimming of the display. kind of like using night mode on a smartphone. Not sure how one would get it to work off the top of my head, but I would think it would be the cheapest and probably easiest way to go about it.

You might also look at these modules:

Sounds like they may have the LCD control you are possibly looking for…

@justjim1220 thanks for that, however it appears that it just turns off the display. I am either looking for a way to drop the backlight lower than default minimum (probably impossible) or some way of putting a layer to block most light.

For those using the official 7" display you can use MMM-Screendimmer
Or write directly to /sys/class/backlight/rpi_backlight/brightness

@emlowe Thanks, but I can’t since I use the 10.1" adafruit display, looking at the pinout it seems there is a way to control it, but I will have to manually wire it to the pi and write up a driver.
