Pixel Qi vs Kindle vs Toshiba R600 vs regular LCD tablet

Side by side comparison video showing the Pixel Qi 3Qi LCD screen next to the E-ink based Amazon Kindle, next to the transflective Toshiba R600 and next to a regular resistive touchscreen tablet laptop. Comparing performance in direct sunlight, in the shade and in a dark room with and without the backlight.

was wondering how it compared to kindle 3 in contrast ratio when in trans-reflective black and white mode?I read a lot so its important to me also watch a lot of video and do video editing so video quality really matters is 1080p led 24bit color possible?preferably led back lighting for improved color pallet brightness and battery life.

@darthsmurff LED or TFT backlighting as far as I know is up to the manufacturer to decide which to use. LED can be setup to use less power. I expect it to be perfect for reading and perfect for video as well.

by the time this video was made kindle was at gen 2 thats a gen 1 kindle,curently kindle is gen 3 gen 2 has better fidelity and contrast than gen 1 and gen 3 is 50% better than gen 2! not a fair or accurate comparison,although the pixel Qi was a prototype.perhaps its been improved.

@darthsmurff Pixel Qi has improved since the video, now it's better in wide viewing angles and can work with a capacitive touch screen and anti-glare matte coating.

Charbax, thanks for these videos which have been THE goto for Pixel Qi demonstration. Just for clarity, can you explain how a Pixel Qi device goes through its three modes of Transmissive, Transflective, and Reflective viewing? I understand that Backlight is the toggle for at least one of these modes... how do you change between all three and what is the difference. Thanks again for your videos on exciting tech!

[Charbax]

@Demasx I only tested the screens briefly for a few minutes each time, and they only had few minutes of time to answer questions. But how I understand it, there is only the backlight, full on is full transmissive, full off is full reflective, and middle to low backlight is still very viewable and also offers color. So if you want color with ambient light conditions, you can use just 20% or 30% of the backlight and it's transflective abilities makes it about as clear as full backlight intensity.

One screen to rule them all.

Since eInk readers are not comfortable in handling yet and just another machine you have to buy and carry around, I'd say the chances are good this new display is the early end of them.

But what's WAY more important is that this is the first display for WRITERS (programmers etc.).

When you have ever seen an eInk device at work you notice that they have high response time and they generate only whole pages! No way this could be the device for writing of any kind. Which our eyes crave for!

i have a great trouble with looking at any screen ,,,,it disturbs my biological clock and cant sleep at night :S,,,,,,,, hope this gonna solve my problem,,,,,,,,,,

[sanperry]

does this have handwriting capability? I would like to be able to edit my writing, including adding pages, making handwritten notes and highlighting...

@sourav777 felt exactly the same!

@radiosnarf

On the other hand, and this is interesting, since the RGB sub pixels all become black in the Backlight off state, the resolution effectively is 3072x600

Oh and BUMP ;)

People like to read books and internet outside in the sun. This middle screen will sell like hotcakes... get it out into production now i want my ebook reader. now. quick.

I wonder how this tech would compare to a Qualcomm's Mirasol display.the video looks better here but the E-ink like functionality, low power cpnsumption(4-6 times less than E-ink), fast refresh times, and full color video support make the Mirasol tech attractive but the video is better on pixel Qi..wonder if led lighting could be integrated with either tech to improve color fidelity,black level and color gamut. neither tech looks as good as oled for video.perhaps an oled overlay would help.
