Plasma business is still growing, according to LG

Despite conflicting reports, LG believes that the plasma display business is
still growing. LG has announced that the utilisation ratio of its plasma
display lines exceeded 90% in August - up nearly 40% from the previous
month. The company said the increase was due to improved product efficiency
coupled with seasonal factors as Christmas approaches.

Kind of a nonsense number for contrast ratio. Extra silly when you
give it 10 bit video with 1000 steps of which it is hard to see even
100. But it sounds good to us silly Americans who just HAVE to have
the biggest, baddest...........

Samsung claims it has the largest 70 inch Full-HD LCD TV in the world
commercially available.

The F9 Full HD LED LCD TV features the latest advanced technologies
including Samsung's LED SmartLighting, which intuitively senses the TV
signal and adjusts brightness by modulating the right combination of LED
backlight units which produces a dynamic contrast rating of 500,000:1.

So all the previous 70 inch Full-HD LCD TV's were smaller? Smile

So the LED's are the backlighting. How many pixels does one LED illuminate?
And just how many pixels is the native resolution on this beast? Anyone
care to take a guess?

And, based on the Sharp implementation of the same idea, the first
thing you will do is turn it off.

It seems to be a terrible idea, as the backlight needs to change when a
part of the picture changes from bright to dark. The other parts of the
picture that don't change will vary in brightness with this backlight
change.

These are not HD news - these are press releases from the company's
marketing department.

Does the whole backlight change? Or could it be they have a backlight
that is segmented into regions that can change brightness independently?
Even if it is one whole backlight, all it needs to do is track the pixel
that is brightest. In dark scenes, the brightest pixel usually is more
dark than in bright scenes. If the change in backlight level and the
pixel levels change in sync and follow the same linearity, you should
not see it. The problems come when a scene has more contrast ratio than
the base contrast ratio of the display under a fixed backlight level.

And certainly not technical product reviews.
