In that case, i can't wait until UHD OELD monitors resolve any lingering concerns about burn-in and then hit the streets at reasonable prices
Quote:I think you are mistaken re: greyscale. Plasma cells are either on or off. Grey scale is simulated by using the subfields. You can see this if you point a shuttered video camera at a plasma, as you can see the subfields clearly.Yeah, i could be mistaken as i'm no expert on plasma tech. However looking at the conclusion within the (admittedly old 2004) document referenced by black_eagle, a document which i have not digested, Dr Cho indicates that the brightness of the plasma cell can be independantly controlled within each subfield by applying special auxilary pulses. So obviously there is much more complexity to plasma and it's probably just as mistaken to simply say plasma cells are either on or off
The talk of subfield rates only began once TFT panel manufacturers started to market higher and higher refresh rates... which is all just marketing mumbo jumbo to confuse people and hopefully sell their product. The reality is that everyone is better off trusting their eyes while viewing any prospective purchases in an environment similar to how the panel will be placed in their home, something which is near impossible in my area as all panels are placed in a very very bright room and the panel set to 'display' or 'retail' mode... hardly a good way to view a future purchase...
And IMHO what is probably still true today, is that my old Pioneer plasma TV provides a fantastic picture that only seems to be bettered by todays high end TFT panels. Mind you, i have not seen any of the new high end TFT panels in a darkened room so these panels may still be inferiour to my old Pioneer in that regard. OELD once sorted out may be the better tech, especially if it does not act as a radiator
Quote:In fact one issue with plasmas in TV studios is that some content can appear to flicker on camera as the sub-fields beat with the camera (particularly on cameras with mechanical shutters like the LDK series)Obviously TV studios have different needs, like wanting a big screen to be in the background and not wanting to have any flicker coming from the panel. We don't want to distract from that lovely weather girl or news presenter do we
As far as monitors are concerned, who knows what will come in future but today it's difficult to find a cheap monitor with QHD resolution and very good color reproduction and viewing angles. And it gets worse when one starts looking at UHD monitors. Guess good prices will have to wait until OELD monitor tech improves so that they can be made cheaper than todays IPS monitors and hopefully resulting in a chase for customers. In any case, i will pay over the odds for any product based on my location
