In the DIGISTONE project a new outdoor digital concrete screen
has been developed. The development towards a final prototype of
the screen involved state-of-the-art LED-technology, optic fiber
technology, and concrete technology.
In order to fabricate the first functional prototype of
DIGISTONE, a completely new fabrication method had to be developed.
Regarding the concrete and light guide technologies an efficient
method to place and fix the light guides in the required positions
was developed. Hereafter a complicated formfilling with a special
designed concrete mix was conducted in order to create the
transparent concrete blocks for the prototype.
4 transparent concrete blocks was arranged in a frame in order
to make the final screen facade of the prototype.
In order to enable live images on the concrete screen the
electronic system was developed. This involved latest LED
technology as well as special designed hardware and software
meeting the requirements in the project. With the special designed
software live images and remote conctrol was enabled.
The final digital concrete screen prototype was then finally
assembled into the frame ready to show live images.
