It sounds insane, but the array that drives it is functionally not that different from the array that individually causes LCD crystals to shift.
I have DLP parts sitting around because they’re cool.

Edit2 explanation:
A white light is focused onto the DLP mirror chip through a kind of kaleidoscopic lens, I’ll spare you the details on that. The individual microscopic mirrors are aligned with charges to bounce light. The mirror array pulses synced frames through the spinning color wheel to create a composite image. It’s a fucking insane idea that barely works… and people like me, with low persistence of vision, are not fooled very well and we see color banding and all kinds of weird artifacting lol
Woah that color wheel… You can see the cyan, magenta, yellow light reflecting but red, green, blue light passing through to the table, respectively. Such a great example of complementary primaries
There is no way that the pictures I’ve snapped can produce the colors accurately. When I look at that small section, it reflects forest green light back to my eye. The light that passes through seems to be muddy yellowish
I tried to find something on the internets. It says something about additional color spaces - in that regard the yellowish color makes sense. and reducing color flickering. 🤷♀️
My assumption was it had something to do with luminosity, but I’m at the end of my technical expertise for this implementation of insane technology lol

I’m so happy you noticed, the colors cannot be reproduced in a digital photo, when it shines in the sun it’s so beautiful!
What’s the 4th color on the wheel used for? White minus white… black, yes. But why?
Straight answer, I don’t know lol
Backlit through window
Toplit by LED lamp
