Has anybody tried to retrofit a transflector into a laptop LCD screen? I've got no idea if this is even possible but I'd love to be able to just trigger a brightness=0 and see a smartwatch-type display that doesn't strain my eyes.

A Pebble monitor, that would be wonderful!

Reminds me of old-school passive matrix LCD displays (https://en.wikipedia.org/wiki/Passive_matrix_addressing https://en.wikipedia.org/wiki/Passive_matrix_addressing) on laptops in the 1990s. It is certainly possible, just not a popular demand for most laptops.

This is precisely what the OLPC screen did and it worked really quite beautifully. Sadly doesn’t look like the spin off company producing the displays went anywhere :( https://en.m.wikipedia.org/wiki/Pixel_Qi https://en.m.wikipedia.org/wiki/Pixel_Qi

I came across a forum post asking about this. As it says you need to remove the polariser layers which is fairly easy (last time I replaced a laptop LCD it fell apart on disassembly and I was presented with many layers of plastic), but OP couldn't find a transreflector layer that was suitable. Without that it's too bright in sunlight, but maybe for indoor use it's good enough. I wonder if something like window tinting films would work (as they are partially reflective depending on the tint level). https://www.instructables.com/community/How-can-I-convert-a-transmissive-to-a-reflective-L/ https://www.instructables.com/community/How-can-I-convert-a-...

  How about carefully placed strips of retroreflective tape behind the display?

I used to have a Toshiba r500 with a transflective screen, it was kinda great outside but kinda crap inside, the viewing angle was abysmal.

Not a retrofit, but the HiSense Q5 seems to be this, new. I don’t own one, but considering it.
