More Information
Summary:A laser type coordinate sensing system for touch module includes an X-direction light emitting array, an X-direction light receiving array, a Y-direction light emitting array, and a Y-direction light receiving array provided at four sides of a touch area on a substrate, so that a plurality of X-direction laser beams projected from the X-direction light emitting array and a plurality of Y-direction laser beams projected from the Y-direction light emitting array densely and orthogonally intersect with one another in the touch area on the substrate. The laser type coordinate sensing system for touch module may be associated with a display panel to form a laser type touch panel.
