Abstract: A quantum structure light-emitting module includes a quantum structure thin film and a light-emitting unit. The quantum structure thin film includes first and second substrates, and an excitation layer that is disposed between the first and second substrates, and that includes multiple quantum structures, which are quantum dots or quantum rods and which are made of cesium lead halide or organic ammonium lead halide. The light-emitting unit includes a first light-emitting element emitting a blue light that enters the excitation layer to excite the quantum structures to emit a green light, and a second light-emitting element emitting a red light. The blue, red and green lights are mixed and exit the second substrate.

Abstract: An optical film includes a blocking layer, and a main body unit including first and second base layers, a working layer and a side surface. The first base layer has a light incident surface and a first surface opposite to the light incident surface. The second base layer has a second surface facing the first surface and a light exiting surface opposite to the second surface. The working layer is interconnected between the first and second surfaces, and includes a plurality of quantum dots, which can be excited by a first light incident on the light incident surface to emit a second light. The side surface surrounds the light incident, first, second and light exiting surfaces. The blocking layer is bonded to the side surface.
