摘要： An optical diode laser touch-control device includes two light emitters and a plurality of receivers around a touch-acting area of a touch panel. The light emitters are disposed on two adjacent corners of the touch panel in the touch-acting area, and each employs a diode laser to continuously project a diffused light through a lens for covering the touch-acting area to form an interlaced touch screen. The receivers, which are capable of receiving the diffused light, are disposed on the touch panel around the touch-acting area to receive the diffused light. As a finger touches the touch-acting area of the touch panel, a part of the diffused light is blocked from being projected onto the receivers, and the touch position of the touch-acting area may be calculated accordingly.
