I went to Fry's the other day, and there was a 42" LCD HDTV on display that uses LEDs as the backlighting. It works by having varying amounts of light supplied to the LCD panel where light is required. The result is blacks that are breathtaking. Problem is, most of us have already purchased our 1080p HDTVs. Do you think many people will scrap the expensive HDTV they have just to get better blacks, or will there have to be a radical improvement before upgrading will occur? I don't consider extreme blacks a radical improvement. It's better, but not worth my getting rid of my current 1080p HDTV which has pretty good blacks.
Interesting thought. One thing I've always found tough is WHEN to make that purchase. It's like putting a stake in the sand and saying, this is the technology that I feel comfortable with putting in my home. I always know that something better is right around the corner, and by next year I'm outdated. I won't be scrapping my 1080p HDTV for better blacks right now, but I look forward to the radical improvements when I do make that upgrade. Interested if someone feels that the better blacks are worth the upgrade??
The caveat with the variable dimming of LED sets is that black levels now vary with average picture level. Since this is done via the TVs processor, there is the potential for artifacts like luminance pumping and halos around contrasting objects. The effective viewing angle is also reduced with these sets. I have always hoped there would be a move back to plasma since its dynamic range is much greater without the use of variables.
That being said, I know plasma is only becoming less popular in the marketplace; witness the exit of Pioneer. Perhaps OLED will be the savior. I just don't see the image quality of plasma or CRT coming from any light-valve technology like LCD.
