Fascinating. By default, though, this seems like it would just result in low contrast and difficulty reading, unless turned to opaque mode.
The thing I'd love to see, which to the best of my knowledge isn't possible with normal HDMI/DP/etc, is an opaque monitor that allows rendering an alpha channel as actual transparency. That would allow things like setting your desktop background to transparent, so that when you have one non-fullscreen window, the rest of the screen is transparent.
Are there any display technologies or protocols for sending RGBA to a monitor, and letting the monitor handle the alpha?
That could be made to work by stacking a transparent OLED panel in front of a transparent LCD panel. The LCD would absorb light, and the OLED would emit light.
I just tried to search for some examples, but I can't find any. Maybe the displays can't be made thin enough to eliminate parallax between the two images?
I mean you could always tag transparency as extra bits. Presumably both sides of the link would need to understand this. So you'd send an 8bpc signal as idk 10, which gets you 6bpc of transparency. Or you run a faster framerate where 1 in every N frames is a transparency. It could work.
