A swept LED screen paints a volume you can walk around

What the record documents

The company now trading as Voxel Photonics states on its own history page that it was previously known as Voxon, that 'the transition from Voxon to Voxel reflects' a change in focus, and that its first product, the VX1, 'first entered the commercial market in 2017'. The same page names three co-founders, including Ken Silverman, credited there as the programmer behind the 1996 engine used in Duke Nukem 3D, now leading 'the core rendering, optics and electronics work'. The company's current line, the VX2 and VX2-XL, is described on its product pages, retrieved 16 September 2026 rather than tied to a single dated announcement; the VX1 itself is no longer described on the live site, so this entry relies on the history page's retrospective mention of it.

What creates the volume

Voxel Photonics describes its current displays as using 'swept-volume LED technology: a high-speed surface sweeps a 2D image through 3D space so fast that persistence of vision builds a true, walk-around voxel cloud'. That is the same family of mechanism as an unrelated 2003 patent for a volumetric display system: a projection screen mounted on a motor 'rotates...about a rotation axis' at high speed - the patent specifies 'at least about 600 rpm' with images refreshed 'at least about 4,000 times per second' - while a stationary projector paints a new 2D slice onto the moving screen for every position it sweeps through. Persistence of vision knits the rapid slices into an apparent solid shape with no goggles, headset, or single fixed viewing position; the current company states the VX2's viewing angle as 'unlimited', consistent with a genuinely walk-around volume rather than a directional one.

Why the image cannot occlude

A swept-volume display of this kind draws every voxel in the volume, from every angle, on every sweep; it has no way to hide the back of an object behind its front, because there is no shared surface for one point to block another the way solid matter does. That is a structural constraint of the mechanism, not a specification the maker discloses or withholds. The current site states no resolution figure and describes no colour depth, so those remain unspecified vendor gaps rather than documented limits.

Questions to bring to a demo

• Can two overlapping objects in the volume ever properly hide one another, or do both stay visible through each other?
• What is the actual voxel resolution, given neither product page states one?
• How does brightness or colour saturation change between the centre and the edge of the swept volume?

What survives scrutiny here is the mechanism, verified by an unrelated but technically matching patent, and a company history that documents its own rebrand openly rather than obscuring the change of name.
