Mirasol and Color E-ink Side by Side
I’m sure you know that I have a Kyobo eReader, the first device to ship with a Mirasol screen. Since I was the only person at CES who owned one, I got a number of requests to compare this color epaper screen with color E-ink. So on Wednesday I went back to the Ectaco booth and took a bunch of photos and shot a couple videos.
Ectaco had a couple Jetbook Colors on display. These are academic ereaders based on the 9." color Triton E-ink display, and they recently shipped in Russia. They’re production models, not engineering samples, so I got the chance actual products – not devices still under development.
I hope you can see the different in the photos, because I won’t have a chance to take more. My Kyobo eReader is deadish, and attempts to revive it have failed. I had planned to look at the photos and shoot a second set if these didn’t work. But I cannot, sorry.
Update: It’s Not Dead! Yay! But I cannot take anymore photos because CES is long past (dammit). Don’t worry, I’m planning to update this post when I get my Jetbook Color review unit. If I have to I’ll take both devices to a pro photographer.
I think you can get something from the video, which is embedded at the end of the post. I shot it in 720p, and if you watch it in full res then you should be able to see how the colors on the E-ink screen don’t shift.
The cover visible on the Kyobo eReader is from the book ButcherBird. I thought it offered a reasonably rich example that would show the changes quickly.
As for me, I could clearly see a difference when I had both screens in front of me.The Mirasol screen had better color quality – but only in the narrow 20% viewing angle. In that small region, Mirasol showed colors that were both stronger and sharper, while the E-ink screen looked distinctly washed out in comparison. But outside that region the color E-ink screen had better color. And of course neither compares well to LCD, but of course we expected that.
The E-ink screen displayed consistent color across its entire viewing area, while the colors on the Mirasol screen shifted quickly once you got out of the 20% region directly in front of the screen.
I’m attaching the photos I took, but only because I cannot get anything better due to the dead device. Feel free to point out the best photos so other readers can find them faster.
