Will definitely be looking out for reviews of this, as well as the Hisense Dual LCD, to see how much of a performance increase these are over the run of the mill FALD. Regardless, will probably be much more interested in the 2020 version of the TCL when they claimed that they may have the control up to 2500-5000 zones. 1000 zones is great, but we've seen similar zone counts in traditional FALD from Sony's Z9D. 5000 would be several magnitudes above anything that's ever been done before. I do recognize that the amount of LEDs in even this first iteration, is way more than we've seen, and should be great for screen uniformity, so that's definitely great also.
TCL said that they will eventually have a TV with 25k zones, but I think that was like 3yrs down the roadmap, if I remember right. A little too far down the road for me.
