1. An optical virtual push button touch panel (1) comprising:
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);
wherein:
the substrate is provided with a mounting slot (100) and a fixed structure (102);
the fixed structure surrounds the mounting slot;
the light emitting member is mounted in the fixed structure;
the light emitting member generates a light source directed toward the mounting slot;
the light guide plate defines multiple light guide structures (120);
the light source of the light emitting member is guided and converged by the light guide structures to produce a light source convergence;
the light permeable plate is mounted on a side of the substrate and covers the light guide plate;
the touch control sensing member is located between the light permeable plate and the light guide plate;
the touch control sensing member defines multiple contact zones (140) aligning with the light guide structures respectively; and
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.
