Lightvert’s ECHO is not a billboard. It’s a brand new display format for the Out-of-Home space.

ECHO creates jaw-dropping, large-scale images without a screen via an ultra-fast scanning projector and a narrow reflective strip mounted on the side of any building. It projects images directly into your eyes that appear to overlay the city landscape.


In a similar way to what you experience after looking directly at a bright light, ECHO uses the Persistence of Vision (POV) effect to essentially ‘print’ images, fleetingly and safely, in the viewer’s eye.

A high-power scanner system breaks down a digital image into columns of pixel data and beams them sequentially off the reflector strip towards the viewer at high-speed. The viewer’s eyes reassemble the image data, allowing them to perceive the full image for a brief moment.
