Abstract

A transparent wearable data display having a source of collimated light, a deflector for deflecting the collimated light into a scanned beam, and a first of switchable grating elements sandwiched between first and second parallel transparent substrates, which together functioning as a first light guide. A first coupling is provided for directing the scanned beam into a first total internal reflection (TIR) light path of the first light guide along the first array column. The grating elements having diffracting and non-diffracting states, in their diffracting state deflecting light out of said light guide. The grating elements are switchable into their diffracting states one group of elements at a time.
