The World's First Blue Light Free Computer

Blue light is not inherently bad, just bad in the wrong context.

Blue light provides wakefulness, stimulation, and sets our internal body clock (circadian rhythm).

When we go outside in the sun, we get bathed in blue lightblue light is not inherently bad, just bad in the wrong context.

Blue light sets the human rhythm.

However, sunlight never gives us blue light without the rest of the visible rainbow + infrared.

Light from screens & LED bulbs do not contain any infrared, and has a unnaturally high proportion of blue light.

LEDs = unbalanced & blue light dominant

Light from artificial sources is especially disruptive at night time, where the high blue light component can interfere with melatonin production and sleep quality at a greater rate than lower energy colors of light. Blue Light has a Dark Side

This doesn't mean that red light is completely innocent of disrupting sleep either

It is both the spectrum of light AND the intensity of light that contributes to sleep disruption. See this tweet from Huberman.

We took all of this into account when building the DC-1 to be the world's first blue light free computer.

The DC-1 has a reflective screen that:

• emits ZERO light during the day

• can be used easily outside in direct sunlight

& a backlight that:

• can be 100% blue light free

• has a broad spectrum of light

• can be seen at very low brightness

Our Live Paper™ display technology feels like a magic piece of paper

During the day, that piece of paper is illuminated by sunlight. At night, that piece of paper is illuminated by candle light.

(backlight is converging with a candle light spectrum)

The two sources of natural light are sunlight & fire.

We are trying to reproduce this experience for the most enjoyable, healthy, and least invasive technology experience for humanity.

Root cause problem solving by emulating nature.

"But can't I just put a red light screen filter on my MacBook?"

Absolutely you can, and we advocate for it

Software screen filters are great, but anyone who has changed their screen to full “red mode” to get rid of the blue light knows the downsides to this…

You can barely see anything and you end up having to crank up the brightness in order to see any contrast.

This is because of the highly isolated nature of LED emissive screens, you can only isolate a very narrow band of colors.

Going full red is not something your eyes have ever been used to seeing.

You need a broad spectrum light solution, and that is what we have in our amber backlight while still being blue light free.

This means you can have a better visual experience, turn down the brightness, and get minimal sleep/circadian disruption.

What about FLICKER?

Nearly all LEDs flicker. Especially when changing in brightness due to Pulsed Width Modulation (PWM) LED driver control

Our LED backlight uses DC dimming & is expert verified flicker-free.

This can only be achieved through hardware changes, not software screen filters.

& Blue Light Blocking Glasses?

They need to be tinted orange/red to block all of the blue light.

Thus the same issues as screen filters (bad visual experience, not solving flicker) + average joe would never wear them.

We still love blue blockers, they just aren't a root cause solution.

We made a computer that is healthier and less stimulating, with a low barrier to entry

Whether you are a staunch circadian health advocate or just like the warm vibes of amber mode and being outside...the DC-1 just feels good because it doesn't make you feel bad :)
