"Flipped" Scanners Launch at DemoFall 2010

These mobile scanners turn things upside down.

[youtube https://www.youtube.com/v/eRmV63eKEGw?fs=1&hl=en_US expand=1]This summer, I speed-dated a few mobile scanners. I didn’t find true love. So I was intrigued when yet another scanner company brought out their products at DemoFall 2010—perhaps I hadn’t seen anything yet.

Rocky Mountain Ventures Company demonstrated two products, the Flip-Pal, a compact $150 personal gizmo appearing in the video above, and the Capture-ID, a larger, $250 product that was demonstrated only in mock-up form, intended for commercial use. Both can scan the typical way, with a document placed face-down on the scanner, or in reverse, with the scanner sitting on the document, and a clear window letting you look down on what is being scanned. It’s this feature that caught my intention—how much easier to position a document when you are looking directly through a window at the scan area, not just guessing. And how nice to be able to scan books or lumpy surfaces that wouldn’t work in sheet-fed or traditional flat-bed scanners.

Alas, however, I didn’t find true scanner love at Demo—the Flip-Pal’s scanning area is optimized for photos; even though the image stitching software is effective, it’s a little convoluted for the typical papers I scan. And the Capture-ID is just too big for my computer bag.

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.
