A backlight module includes a light source, an optical film, and a light control film. The light control film has a first reference surface and a plurality of first optical structures disposed on the first reference surface. Each of the first optical structures has a first optical surface and a second optical surface. A first included angle is formed between the first optical surface and the first reference surface. A second included angle is formed between the second optical surface and the first reference surface. The first included angle is an acute angle and is smaller than the second included angle. Thereby, the light can be deflected to one side and the light output of the other side can be suppressed. This invention also provides a display device including the backlight module.

An optical film includes a substrate layer and a plurality of optical layers stacked on the substrate layer. The at least two optical layers have microstructures that complement to each other. The optical layer close to the substrate layer is the first optical layer, and the optical far from the substrate layer is the second optical layer. The refractive index of the first optical layer is smaller than the second optical layer, and the microstructure of the second optical layer has an acute angle. Because of the arrangement of the optical layers, the contrast of light intensity can be reduced, and the uniformity can be improved. The invention also provides a backlight module and a display device including the optical film.

Optical film, backlight module, and display device

A backlight module includes a light source, a light guide plate, and a quantum dot enhancement film. The light guide plate has a light-incident side that faces toward the light source, a surrounding side that is connected to the light-incident side to constitute an outer periphery of the light guide plate, and a microstructure unit that is disposed adjacent to the surrounding side of the light guide plate. The quantum dot enhancement film is stacked on the light guide plate.

A light guide element and a lamp are described. The light guide element has a length and an angle of total reflection. The light guide element includes a light-incident surface, a light-emitting surface, a first reflecting surface, and a second reflecting surface. The light-incident surface includes a first outer peripheral edge and a first inner peripheral edge. The light-emitting surface includes a second outer peripheral edge and a second inner peripheral edge. The first reflecting surface connects the first outer peripheral edge and the second outer peripheral edge. The second reflecting surface connects the first inner peripheral edge and the second inner peripheral edge. An angle is formed between the first reflecting surface and the second reflecting surface. The angle is smaller than the angle of total reflection, and the length is greater than a predetermined distance divided by tan the angle of total reflection).
