A light source module includes a light guide plate, a light source, a first prism sheet, a second prism sheet and a third prism sheet. The light guide plate includes a light emitting surface, a bottom surface and a light incident surface. The light source is disposed on the light incident surface and emits a beam into the light guide plate through the light incident surface. The first prism sheet is disposed on the light emitting surface and includes a plurality of first prism units located between the light emitting surface and the second prism sheet. The second prism sheet includes a plurality of second prism units extending in a first direction and located between the first prism sheet and the third prism sheet. The third prism sheet includes a plurality of third prism units extending in a second direction. The first direction is perpendicular to the second direction.

Light source module and prism sheet thereof

A light source module includes a light guide plate, a light source, a first prism sheet and a reflection sheet. The light guide plate includes a light exit surface, a bottom surface opposite to the light exit surface, and a light entrance surface connected to the light exit surface and the bottom surface. The light source is disposed beside the light entrance surface and adapted to emit a light beam to the light entrance surface. The first prism sheet is disposed on the light exit surface and includes first prism units. A surface of the first prism units faces away from the light exit surface. The reflection sheet is disposed on the bottom surface. The light guide plate is located between the reflection sheet and the first prism sheet. The reflection sheet includes microstructures. A surface of the microstructures faces the bottom surface of the light guide plate.
