Video: World's biggest touchscreen display is 82-inch beast

Well this may be the first / biggest of its size but really the specs are not that good.
First:
6" thick is not slim. Look at the latese samsung LED TV's they are 1". And why build it LCD in the age of Plasma and LED.

Second:
Standard HD resolution on a 80" TV looks fine from 8 feet away, but standing there touching it, you will need much more resolution. My 23" monitor with HD resolution (1920X1080) is barrly acceptable.

Well at least it is fast and reliable.

I imagine they couldn't go with LEDs because it would make the display astronomically expensive. Nowadays most LED Displays are built as LCDs with LED backlight located on the top or (in more expensive models) around the circumference. As a result, backlight only shines around the edges and special diffusers spread the light evenly over the whole screen. Seems like it would be tough to have even brightness/contrast on a screen of that size. Alternatively, they could build it with OLEDs, but we're talking REALLY big bucks there.

By the way, if your 23" monitor had resolution higher than 1080p, you would have a really hard time seeing things on it because objects would be simply too small. I'm just saying.

Roughly twice the size of your bigger flat screen TVs (58 inch). It will be interesting to see how much more a touch screen will cost than an ordinary TV of the same size.

Headline writers a little to enthusiastic or lack of research? Just Google "largest touchscreen" and you will find multiple examples of screens much larger.

Impressive work. looking nice. you have to take lot to manage it.
