pixels             …everywhere.

Pixels in X, Y, and Z

Almost all displays are more-or-less two-dimensional –so many pixels in the ‘x’ dimension and so many in ‘y’. So-called 3D displays really aren’t 3D –the 3rd dimension is an illusion, created using a variety of

techniques including  polarization switching, lenticular lenses, shuttered glasses, and so on.

But if pixels are really going to be everywhere, why should they be restricted to just two dimensions? They don’t, of course, and people are experimenting with this.

I was looking at hackaday.com recently and found this post about a 3D LED cube assembled by Brendan Vercoelen while he was a student at New Zealand’s Victoria University. His goal was to make a 16x16x16 matrix of red/green LEDs (4096 of them) but he stopped at 16x16x8. That’s still very impressive when you consider he built this by hand — each LED has 3 connections to it which meant he did a lot of soldering. The first video below is from his site.

Others (experimenters and companies) are also exploring this. For example, Instructables.com tells you how to build a less-ambitious version yourself ( see 2nd video further down this posting). Seekway in China seems to be selling something similar using layers of LED curtains (perhaps readers who know Chinese  can comment more about what Seekway is doing).

Is this a practical 3D display? Probably not, but maybe that’s not the point. Maybe it’s simply a new and different way of expression, one more part of the digital light future.
