Abstract
A switching module capable of adjusting a visual angle is disclosed. The switching module includes an edge-type optical substrate, a light source disposed by a side of the edge-type optical substrate, and an optical modulating component disposed between the light source and the edge-type optical substrate. The edge-type optical substrate has an emitting surface. The light source includes a plurality of light units. Each light unit can emit a beam to the edge-type optical substrate according to a predetermined angle. The optical modulating component can modulate divergence of the beam emitted from the light unit, so that the beam can be guided out of the edge-type optical substrate via the emitting surface according to the predetermined angle.
