Abstract:
1. A touch device, comprising: a light guide, having a plurality of light guiding blocks, and at least one slot, each of the plurality of light guiding blocks including a side incident surface, a top emissive surface, a bottom surface, and, an isolating gap formed between any two adjacent light guiding blocks of the plurality of lighting guiding blocks to separate the two adjacent light guiding blocks, wherein the side incident surface of at least one first light guiding block is formed along the isolating gap and faces the isolating gap, and the light guide is a single plate; a plurality of light-emitting modules, disposed corresponding to the plurality of light guiding blocks, at least one first light-emitting modules being disposed in the isolating gap and each of the light-emitting modules being adjacent to the side incident surface of the corresponding light guiding block for emitting light that is guided to the corresponding light guiding block, and the light being guided out of the top emissive surface of the corresponding light guiding block; and a plurality of touch sensing modules, disposed correspondingly to the plurality of light guiding blocks, each of the plurality of touch sensing modules being disposed on the bottom surface of each of the plurality of light guiding blocks, wherein any one of the plurality of touch sensing modules generates a driving signal to control a corresponding light-emitting module of the plurality of light-emitting modules for emitting light when sensing a corresponding light guiding block of the plurality of light guiding blocks is touched.
