Hi, I and many others share your desire to work outside and not feel fatigued after working with a digital device.

Making a quality transflective screen suitable for laptops and having good viewing angles is a complex manufacturing process; companies are working on it. I hope in the future this becomes viable.

At EI2030, we are working on making an open-source and open-hardware e-ink laptop and tackling the challenges. Our first pre-prototype Archer is almost complete, and we are going to start working on our second prototype.

> I love to somewhere surrounded by nature, open my laptop and use my phone as hotspot, but I feel the fatigue after some time…

I think this has more value than just working somewhere in the arms of nature. The fact that we no longer see sunsets as often as we should and with mobile phones and modern IPS panel screens constantly feeding daylight (morninglight) spectrum through our eyes into our brains, we stifle our body clock [1] too easily.

A screen that works outside of the covered space or even in the sunroom of my house would mean a lot. It will offer better sleep patterns than today.

I had one of those display panels on a rugged Win7 tablet and it was pretty impressive.

Would you say it could be possible to code with such display if it was attached to a laptop?

I have an old Acer Aspire One netbook which I modded with a Pixel Qi display. It is definitely usable for programming in direct sunlight, though the display is physically too small to get comfortable doing a lot of programming on it. Funnily enough, the major problem is not enough sunlight -- indoors, you can use the backlight, and direct sun provides a good contrast ratio outside, but in the shade outdoors, particularly after my eyes have adjusted for sunlight, the screen becomes difficult to see.

Hmm, I see. Did you have problems to adjust to other normal screens too, or it was just with that Pixel Qi one?

Just the Pixel Qi. In indirect light, the contrast ratio is much lower than, say, a Kindle, which is itself much lower than paper. So unless the sun is directly on it, it's harder for sun-adjusted eyes to read than a Kindle, or than it is for indoors-adjusted eyes to read a normal backlit LCD.

I'd really really love a Qi or even better, an eInk laptop. Black and white would be fine. Colour eInk has too bad refresh rates anyway(or useless colours with LCD overlay like eInk Kaleido) For text terminal work it would be fine and the laptop could be really low spec (think raspberry pi kind of specs)

I live in Spain and it would be really nice being able to do some light work outside in the sun. You can do it with some regular laptops (especially with HDR displays) but it will kill battery life and you'll still end up squinting. It's really sad that PixelQi went out of business.

You can get pretty close with an Android eInk tablet like the Boox Note Air and a Bluetooth keyboard with Termux.

Close yeah but not really comfortable on the lap or anything.

I always hated the Surface Pro style tablets. Or those Apple keyboards for the iPad. I've tried them but sold them again, they were a horribly unstable contraption.

For me a laptop has the keyboard firmly attached to the screen at all times :) Especially for portable use.
