In 2013 we were asked to investigate if it is possible to build a "billboard" using optical fiber instead of LED's. This with the aim to make the product more economical and lighter in weight.
We first build a one 1 meter square fiber screen by hand using a grid 50x50 fibers. These 250, 0.5mm plastic optical fibers came together in a square bundle in which we projected video using a small video projector. This looked promising for indoor applications and really light weight < 2Kg/m2.
Then we build and adjusted a robot to insert fibers automatically and create a fiber screen semi automatically
