We started Pixun because computer screens cause a lot of unnecessary pain and negative health effects. As former researchers in biology and human vision, we are familiar with the latest research on why this is happening and how we can solve it.
Pixun's founders both suffered negative health effects stemming from overexposure to artificial lights and computer displays, and now that we understand the problem, we are passionate to bring a solution to the world. We believe this is the place and the time to start a healthier, nature-based tech revolution.
Our vision is to redefine computer displays by bringing full-spectrum natural light into all your digital images.
Daylight is captured by an external solar light collector and channeled into the display through an optical fiber cable. This full-spectrum natural sunlight is then used to backlight a computer screen. Whenever sunlight is not available or not sufficient, an electric source can take over.
Yup, it is what the word actually means, not some electric imitation! Daylight is always tuned optimally for the time and your location, and whatever the outside lighting condition, we channel that into the display in a fully analog way.
Indoor light levels are always much lower than outside and the direction of light keeps changing with the time of day and weather conditions. Furthermore, window glazing also significantly filters daylight. Gathering daylight outside and channeling it indoors is therefore the only viable way to get sufficient daylighting for a display with high image quality.
A positive lens tracks the sun's position and concentrates light into the end of a fiber-optic cable. These systems only require a tiny amount of electricity to aim the lens. So, once the system is installed, daylight is provided for free throughout the day for many decades.
The whole visible and near-infrared spectrum are preserved, which is the most crucial feature of Pixun regarding its health effects.
To be on the safe side, we filter out ultraviolet completely. However, if there is a need for it, we can technically keep some of the UV also in the spectrum.
Reflective displays operate with the ambient light in their surroundings. Since this provides a much lower quantity of light than any regular display light source, their image quality needs to be reduced to achieve usable brightness levels. Similarly, the direction of light changes all the time. These limitations make reflective displays most ideal in small and portable applications, where the best use case is outdoors in ample daylight. However, they cannot really replace a regular display in an indoor office or home setup.
Pixun is the only display solution that can offer all the health and comfort benefits of daylight in a display, without any sacrifice in image quality or usability relative to regular displays. So, it has the same resolution and visual image properties as your usual computer screen and it can be placed in any indoor space (even in a dimply lit or windowless room).
Absolutely! Fiber-optic solar collector systems have long been operating successfully in Sweden, Denmark, or other northern climates. In sunnier places, operation is more efficient and the size of installation needs to take that into account (a larger collector might be needed if you live far north).
If clouds occlude daylight too much, Pixun's inbuilt electric source can supplement light or even take over completely (e.g., for night use) so that the display is fully functional any time of the day or night.
Yes! Pixun has an electric source to illuminate the display when daylight is not available. It also has a sleep-friendly night mode with all the near-infrared frequencies still present to promote optimal recovery for the eyes and the whole body.
Blue light from the sky is vastly different from the blue light that earned the bad reputation that we associate with this term when it comes to displays and electric light sources. This is because the tissue stressor effects of blue light act differently depending on the rest of the spectrum (see also References).
During the day, we strongly need this blue light for optimal health — but in natural light, it always comes balanced with all the rest of the spectrum that protects from the tissue stress. This happens both concurrently as well as through the gradual changes in spectrum that cue our bodies to prepare in advance.
Electric sources lack both of these properties and therefore blue light from a narrow-band LED or OLED source has a different physiological impact than high color temperature daylight at noon.
No! Daylight is channeled into the display in a fully analog manner and no further flicker is introduced by the display either.
With OLED (or CRT...) displays, the refresh rate is directly linked to flicker — however, it is just a common misunderstanding that this would also be the case with LCDs. In most LCD screens, the source of flicker is the backlight, while the LCD itself can also add flicker in some applications. We have eliminated both of these flicker sources.
Absolutely, the display itself has an adjustable stand and VESA compatible mounting, so you can use it in any desktop or wall-mounted setting and adjust its position the usual way.
