Abstract
A touch device is provided, which includes an elastic material layer, a photosensitive layer and a touch layer disposed in sequence; wherein a key region is disposed in the touch layer; at least one deformable pad is disposed in the elastic material layer and each of the at least one deformable pad has a plurality of deformable blocks; some or all of the deformable blocks of the deformable pad are deformed so as to vary lights incident on the photosensitive layer in response to a corresponding position of the touch layer being subjected to a pressing operation; an electrical signal at a position of the photosensitive layer corresponding to the pressing operation changes in response to the photosensitive layer sensing a change in lights.
