Why not ? they can make them ,So why not release Displays that are larger panel than a 80" ? The 80" Displays are Very Nice I have one & I love it .

Well, we all know what LED local-dimming means, that it has been around since Sony released its first implementation 3 years ago and that its main "problem" is that "halo" effect that might be visible due to the large size of LED zones illuminating much smaller white objects during expanded black scenes - starfields particularly.
Home Theater Magazine has been reporting on this issue since the magazine tested the first LCD HDTV with the technology about three years ago, a Sony model, and they found the tremendous increase in contrast ratio more than made up for its shortcomings, aka, "halos".
In fact, on their report on a newer LG model with local-dimming that has more LED zones than most others units, they found that "halos" were a non-issue, non-existent.
If the Sharp Elite implementation of LED local-dimming is "crippled" in any way it would be difficult to relate considering that the 60" Elite has reportedly 240 dimming zones and the 70" Elite has 336 zones.
About one year ago HT magazine tested a LED edge-lit model from Samsung offering variable dimming and they commented extensively on its effectiveness for that particular model, with its black level measuring close to 0.001 ft-L, comparable to models with local-dimming.
Before i purchase any of these new XXX-large LCD panels with LED backlighting but no local-dimming i will certainly try to read reputable test reports to get a handle on their native contrast ratio versus LED-dimmed contrast ratio, that's for sure...
