Hi,

Hopefully the LG team can shed some light on this matter as there seems to be some conflicting information about the upcoming PG7000 Series of Plasmas.

Statements by LG at IFA state that the screens have a "Dynamic Contrast Ratio" of 1,000,000:1 where as the UK LG website merely states the "Contrast Ratio" of 30,000:1. As Dynamic Contrast Ration numbers are totally meaningless these days, I am intrigued as to what the real life true contrast ratio actually is. LG had initially declared these sets as "Infinite Black"/"Infinite Contrast" Screens with true blacks and this was confirmed by Joakim Ornstig of LG Nordic who is on record of stating:


"LGs new plasma has an absolute blackness

"Blackness that quality has been taking hold in the television industry. Now Korean LG announces a full-hd plasma with infinite blackness, and the release by the end of July.

How well a television really is determined by a number of factors such as color, uppskalning and various so-called bildförbättrande methods. But blackness is the parameter that has been by far the most attention in recent years, and perhaps it is not so strange. With deep blackness is a greater sense of three-dimensional image and color improved across the whole spectrum. Nevertheless, we need subdued lighting, preferably completely darkened room, to really be able to understand it better picture.

The technical difficulties of complete blackness has touched plasma cells grundladdning emitting some light even when the cell to be idle. At this year's CES exhibition showed Japanese Pioneer up a prototype that does not leak any light at all, thus infinite blackness, and this year's G9-panels will be significantly black than it has already paid tribute to the previous generation.

All this has apparently LG taken up and quietly has developed its own technology. When we heard the rumour that LG already this year, with infinite contrast in their plasma panel we became sceptical. But the rumour proved true:

Yes, PG7000 coming at the end of July has completely black representation, confirming Joakim Örnstig, television specialist at LG Nordic region. We have managed to eliminate grundladdningen (idling luminance) and black when measured up to zero candelas. This compares with 0.03 candelas as our model PG6000 will continue Joakim.

PG7000 is a full-hd plasma but, according to LG, the technology later this autumn, also to models with standard hd-resolution."

So, I hope the LG team will give finally give us some clarification about the PG7000 Plasma's and if they really do have the "100% Black Panel" as we have all been informed or not - there are a ton of folks around the world who have been waiting patiently for these sets hoping that LG is not on just some marketing exercise and that they will deliver on Absolute Black Plasma's! The ones shown by LG UK also have that (horrible!) silver strip at the bottom when the ones shown at IFA did not - I hope LG really do not give us these!

I saw this set for a good 15mins at the show (60") and was really impressed with it's performance. It has improved black levels and certainly the best colours yet for an LG screen. Blacks are very good and by eye the native contrast also looks like it is better than past models. It certainly doesn't, in my opinion, have non emissive black technology on board and to be honest, the company certainly were not describing it as such at IFA - although they may be elsewhere. One interesting feature is the 600Hz sub-field drive technology, basically as I understand it, the set shows 50 frames per second with 12 subfields flashing within that second, they then call it 600Hz sub-field. It could be said that it is a bit misleading and confusing in the PR terms as its not 600Hz in teh conventional frame inetrpolation terms that we are used to. But it didn't look that bad, but I would like to do some in-depth testing on on to see exactly what is going on.
It is featured in some detail in our video coverage due later today in the final IFA video coverage along with Samsung and Toshiba stands.

Hi,

Thanks Phil,

This set certainly seems to metamorphise on a near continual basis whether its marketing or performance issues! It's getting beyond a joke now!

You could go and see it for yourself at LG's launch next week, there is a thread here inviting forum members to send the LG team a PM to get an invite. I will be going along to have a further look at the new plasmas in some detail as my time was limited at IFA. I will hopefully have some video material to show for those not able to go along.
