Patent attributes
The present disclosure discloses a light emitting touch pad device including a circuit board, a plurality of sensing elements, a light guiding plate, a light emitting component, and a plurality of first spacing blocks. The sensing elements are disposed on the circuit board, and a distance between geometric centers of two adjacent sensing elements is a first length. The light guiding plate is disposed above the circuit board, and includes at least one light spot area and at least one nil-light spot area. The light emitting component emits light toward the light guiding plate. The first spacing blocks are disposed on the light guiding plate, and are located in the nil-light spot area. A distance between geometric centers of two adjacent first spacing blocks is a second length, and a spacing distance between two adjacent first spacing blocks is a third length.
