Abstract: A backlight module includes a light guide plate, a light source, a prism sheet and a reflective structure. The light guide plate includes a light emitting surface, a bottom surface opposite to the light emitting surface, a light incident surface connected with the light emitting surface and the bottom surface and a plurality of micro structures located on the bottom surface or the light emitting surface. The light source is disposed beside the light incident surface of the light guide plate. The prism sheet is disposed above the light emitting surface of the light guide plate, and includes a plurality of prisms facing the light emitting surface. The reflective structure is disposed under the bottom surface of the light guide plate. The reflective structure has a characteristic of changing its reflectivity according to a control signal applied thereto.

Abstract: An optical module and a light source are provided. The light source includes a circuit board, a plurality of light-emitting element chips, a plurality of total reflection elements, an encapsulant, and a plurality of optical wavelength conversion particles. The light-emitting element chips are disposed on the circuit board. Each of the light-emitting element chips is adapted to emit a light beam. The total reflection elements are disposed on the circuit board. Each of the total reflection elements is configured adjacent to one of the light-emitting element chips, a partial light beam of the light beam emitted by the one of the light-emitting element chips enters the total reflection element, and is transmitted in the total reflection element, and emits out from the total reflection element. The encapsulant covers the light-emitting element chips and the total reflection elements. The optical wavelength conversion particles are distributed in the encapsulant.
