My husband and I bought our first full-HD (1080P) TV set this weekend. Despite living in Silicon Valley and being immersed in technology, we’re not exactly early adopters. But we needed a new TV quickly (before the Sunday Giants game), so we made a fast shopping trip on Saturday and ended up with 1080P model. Personally, I see no difference between the 720P and 1080P resolutions in the 32-inch diagonal size we were in the market for, but my husband wanted “better” resolution, so we went for it.

He's happy with our new HDTV. So I don’t really have the heart to tell him that we’re about to fall behind the technology curve once again, because LG and Sony are both going to ship televisions with resolutions of 3840 by 2160 pixels in time for the holiday season. They had both been calling this resolution “4K”, but last week that moniker became dated when the Consumer Electronics Association (CEA) voted to tag this next generation of displays “Ultra High Definition”, or “UltraHD.” The CEA also announced that it expects to see a lot of product introductions in this resolution at the January 2013 Consumer Electronics Show.

These won’t be cheap. Sony’s 84-inch diagonal 4K TV (the company isn’t eager to embrace the UltraHD name) will cost about $25,000; LG’s model is a comparative bargain at about US $20 000.

What’s the point of UltraHD? In smaller screen sizes, there isn’t any; the technology will only be meaningful for extremely large TVs. And there’s not a lot to watch at home in this higher resolution. While movies for theaters are recorded in this higher resolution, so far, there have only been a few test broadcasts of television programming—for example, by the BBC during the Summer Olympics. So, for the time being they’ll be taking HD video signals and filling in the missing pixels by extrapolating from the existing ones.

Digging Into the New QD-OLED TVs

Formerly rival technologies have come together in Samsung displays

Sony's A95K televisions incorporate Samsung's new QD-OLED display technology.

Televisions and computer monitors with QD-OLED displays are now on store shelves. The image quality is—as expected—impressive, with amazing black levels, wide viewing angles, a broad color gamut, and high brightness. The products include:

All these products use display panels manufactured by Samsung but have their own unique display assembly, operating system, and electronics.

I took apart a 55-inch Samsung S95B to learn just how these new displays are put together (destroying it in the process). I found an extremely thin OLED backplane that generates blue light with an equally thin QD color-converting structure that completes the optical stack. I used a UV light source, a microscope, and a spectrometer to learn a lot about how these displays work.
