Pixel QI displays

curstpriest · 11-06-2010, 07:15 AM

What do you all think about Pixel QI displays?
I have a 10.1 sub-notebook that uses a samsung display (supposedly this replaces that model), and a 250$-300$ a replacement screen that offers a reflective mode is kind of an interesting option. With standard battery I get about 4 hours, with large cell I can get 6-8 with normal backlighting.

They compare it to a kindle in E-ink mode in some of their older photos

Panel vs LCD

Resolution T 1024x600xRGB (transmissive) resolution (normal mode)

Panel vs E-ink

Resolution R 3072x600 (reflective) resolution (desaturated mode)
Appearantly you get 3x the resolution when you enable the "e-paper" mode

The background on the pixel qi looks really muddy. Contrast looks poor compared even to the old kindle. I have a feeling this thing sucks both as a LCD and e ink display.

it actually looks quite good,

that's just some low rez photo

The resolution is like 3x higher than the DX?

I bet you are right.

This article shows it much better, there's a video. The contrast in sunlight with backlight off compared to late gen E-readers reveals that you do not get as high of contrast as real e-ink displays, but you get full refresh, so you can navigate the web, pdfs, videos etc normally, which is a huge benefit to many users, and a big issue for people who need to work outdoors or in direct light.

Look at this video comparing it took traditional displays:

here's the company's product video with demos, they also talk about how they make it and such:

I don't think a photo or video can really tell us what we want to know about this technology. That's only going to happen when independent reviewers (or perhaps ourselves) can get production devices in their hands. Even then, there may not be a consensus because everybody has different requirements and usage patterns.

Presumably it is at least clearly superior to conventional LCD in strong light - that is its entire reason to be. There will be applications where that capability is decisive (I'd love to have this display on my handheld GPS). Whether it would function well for a dedicated ereader device is another question.

It seems pretty impressive. But at the same time, you have to wonder why no one is really using it?

It just came out, watch the video, she said that they can't make everything themselves, they have to rely on the major manufacturers (I think there are like only 2 major ones out there) that add additional steps to existing LCD fab. As they explain it, they add another metal layer, and then create a small hole in each pixel to allow light to pass through for the backlight, then reflect light through this opening, which also allows it to reflect light off of the mirror in direct sunlight as well (because of the metal layer).

It's new, look @ the exp of devices, they only have a 10 in display right now but are working on 6 in and others for other portable devices. It's likely you will start seeing this technology in many other devices because it is cheap and easy to manufacture.
