Yes! This is what's used on certain pro LCD monitors to give them insane 1,000,000:1 contrast e.g. http://flandersscientific.com/XM310K/index.php, as well as theatrical Dolby Vision projectors: you align the two 2000:1 panel/chips and the contrast of one is multiplied by the other, I never thought I'd see this on a consumer level display. Doesn't mean that Hisense's application of it is any good, but it's VERY interesting nonetheless because it means that these panels are being made affordable for tech manufacturers to use in consumer products, and using a 1080p panel just for the greyscale part is a shrewd move as it doesn't really need to be 2160p rez.

[edit]

Penton mentioned in the HDR discussion thread that Sony will be migrating their BVMX300 OLED mastering monitor over to one of these dual LCD panel doohickies, so as to provide the same sort of contrast and black level BUT to also provide higher peak brightness and cut down on image retention problems.

If Sony came out with one of these for the consumer TV market, oh boy...
