VR headsets are now technically much more mature than a few years ago – but the picture is still not really sharp. Varjo wants to change this with a headset that displays the currently viewed area very sharply. We tried a first prototype.
At the start-up conference Slush 2017, the Finnish start-up Varjo showed a first prototype of its VR headset. The Varjo headset looks like many other headsets, but inside the device offers an interesting technical detail.
The Varjo headset has not just one, but two displays. The main display, referred to by the manufacturer as a context display, sits like other manufacturers right in front of the user. The second display sits in the lower part of the headset and is basically not visible to the user.
The second display, like the Context Display, has a resolution of 1,920 x 1,080 pixels, but is considerably smaller with a screen diagonal of 0.7 inches. With a pixel density of almost 3,150 pixels, the tiny OLED screen offers an extremely sharp image – much sharper than that of the main screen.

The image of this additional screen is mirrored onto the large display with the help of a mirror, where it displays the same contents much sharper. The idea is that with the help of eye tracking the user’s point of view is captured and there always the sharper image of the second display is displayed. The movement of the image should be made possible by means of a movable mirror.
Varjo calls this system Bionic Display because it corresponds to how the human eye works. Again, only the part is sharp, to which the point of view falls concrete; the rest of the field of vision is blurred.
