Abstract
A touch device includes a light guide having a plurality of light guiding blocks, a plurality of light-emitting modules, and a plurality of touch sensing modules. Each light guiding block includes an incident surface, an emissive surface, and a bottom surface. An isolating gap is disposed between any two adjacent light guiding blocks. Each light-emitting module is disposed adjacent to the incident surface of a corresponding light guiding block for emitting light that is guided thereto, and the light is guided out of the emissive surface thereof. Each touch sensing module is disposed on the bottom surface of the corresponding light guiding block. Any one of the plurality of touch sensing modules generates a driving signal to control a corresponding light-emitting module for emitting light when sensing a corresponding light guiding block is touched. Therefore, each light guiding block can emit light independently.
