I guess this would also be a nice improvement for smartphones' screens since you would only need to power half the number of pixels for the same equivalent density which will save on the battery

Nya, the light will have to travel through two LCD layers, if I've understood it correctly. You'd need a very powerful backlight.
In the video, some of the captures for the cascaded displays were actually brighter (eg: 4:20 mark). I'm not sure why and it looked like they were just using a single display's backlight. Anyone know?
