British inventor Andrew Fentem has come up with a way of cheaply turning fabric into large active displays. Fentem, who pioneered multitouch input technology 15 years ago, only to see a UK quango squander the innovation and Apple reap the reward, calls the new display “organic pixels”. He’s invented an ulta-thin magnetic actuator, fractions of a millimetre thick, which can be applied fabric to create a “pixel”. The programmable actuators create enough of a magnetic field to “flip” the pixel. This allows a vast display to be created at much lower cost than an arena-scale LED display.
