This one is free, and isn't too technical, as the math is at a low college level. Other than that, it can be easily seen that IGZO has a better color response, which is very important.
So, thinner, brighter, less power, and better color.http://www.eecs.umich.edu/omelab/dow...20Displays.pdf
I don't see evidence of "better color", neither subjective, measurable or more accurate in your link. In fact the study conclusions don't mention thickness or color at all. I do recall from other supposedly reliable mentions that thickness is a consideration, but it wasn't the display itself that was thinner. On the contrary, some current screens are significantly thinner. Instead, because there's fewer transistors in a 300+ppi IGZO-layered display compared to a traditional TFT-LCD screen of the same resolution, it means reduced power draw as well as a brighter display without those transistors in the way. At least that's the way I read it.
A by-product of the improved brightness is that Apple could avoid needing a second backlight source for a hi-res display in the iPad 3, allowing the iPad itself to be thinner than it otherwise would need to be to accommodate the extra hardware.
So Mel, if I'm correct ( I believe I am) it's not the display itself that would be thinner. It's the brighter light transmission characteristics of an IGZO-type display that requires less backlighting, and reduces both power needs and hardware needs while achieving good display qualities.
By the way, the same IGZO technology can be used in both OLED and LCD screen applications according to what I've found. Apple would be unlikely to use the OLED display simply due to current cost differences, making LCD their rumored choice.
In any case tho, thanks for taking the time to try and find an appropriate and understandable link Mel. Unfortunately that one will still be beyond most members here I suspect. I hope I've at least given an accurate poor layman's explanation.
