摘要 |
A light reactive medium comprises an imaging layer reactive to radiation of a first frequency to exhibit a visible change, and a further layer above the imaging layer, the further layer being changeable from being substantially transparent to said first frequency to being substantially opaque to said first frequency, in response to electromagnetic radiation of a second frequency substantially different from the first frequency, the at least one other layer being at least partially transparent to visible light reflected from the imaging layer while being opaque to said first frequency. Also disclosed is a lenticular imaging method in which a lenticular layer is provided over the imaging layer, and images to be viewed from different directions are written using light incident at different directions. Also disclosed is a phosphorescent display that may be used to display lenticular images. |
