Abstract
A photosensitive button structure includes a button body and a photosensitive layer. The photosensitive layer is disposed on a bottom side of the button body, and has a plurality of words and pictures formed thereon. Whereby, the photosensitive layer produces a first color change by absorbing light from one angle, and then produces a second color change or more than two color changes by absorbing light from another angle, in order to produce a dual mode visual effect. The present invention solves problems and the defects of the traditional button having only one fixed color, and that the color of the traditional button can only be changed once, because the photosensitive layer can absorb light from different angles. Hence, the present invention not only improves the appearance of the button body, but can also show more than two color changes of any words or pictures on the button structure.
