摘要： An optical virtual push button touch panel includes a substrate (10), a light emitting member (11), a light guide plate (12), a light permeable plate (13), and a touch control sensing member (14). The substrate is provided with a mounting slot (100). The light emitting member is mounted in the substrate. The light guide plate defines multiple light guide structures (120). The light permeable plate is mounted on the substrate. The touch control sensing member is located between the light permeable plate and the light guide plate and defines multiple contact zones (140) aligning with the light guide structures respectively. One of the contact zones produces a coupling capacitance through the light permeable plate and drives the light emitting member to generate the light source, and one of the light guide structures converges the light source toward one of the contact zones.
