There was a certain amount of media hand-wringing surrounding January's CES, the big kahuna of consumer electronics trade shows held annually in Las Vegas. Where was the big game-changing product? CES was so over.

It's true that it's been a couple of years since, say, smart watches arrived on the scene, and a full five years since the last really big new product category—tablets—was introduced. But new categories tend to leave an innovation hangover: In a rush to grab market share, funding and engineering talent tend to get focused on me-too products. In contrast, this year's exhibitors were presenting a lot of different ideas pushing in a lot of different directions.

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.
