One very recent application of LEDs is to be found in the Sensacell tile. The tile contains an array of LEDs and modular sensors that can detect objects closer than 6″ through materials such as glass, plastics, wood and tile. When an object is detected, a LED is activated. The system’s network can also interface with a computer which can then control any module in the system, allowing moving images to be created.
Moving images can also be produced using illuminated roof tiles designed by Lambert Kamps. The idea is based on the words often ‘written’ on roofs using coloured roof tiles.Translucent polyester roof tiles are illuminated with LEDs and each tile can acts as a pixel and be controlled by a PC”….
