An optical film comprises a light incident side and a light emitting side opposite to the light incident side. A plurality of light incident microstructures are formed on the light incident side, and the light incident microstructures are tapered structures. According to the structural design of the light incident microstructures of the optical film, the light field of a light source can be expanded to achieve the purpose of emitting light at a specific angle. The invention also provides a backlight module and a display device including the optical film.

Optical film, backlight module, and display device

An optical film, an optical film set, a backlight module and a display device are provided. The optical film includes a main body, plural first prism structures and plural second prism structures. The main body has a first optical surface and a second optical surface. The first prism structures are disposed on the first optical surface. Each of the first prism structures extends along a first direction. The second prism structures are disposed on the second optical surface. Each of the second prism structures extends along a second direction. The first direction is different from the second direction.

Backlight for display having an optical film with first and second prism structures disposed on opposing optical surfaces thereof, or backlight for a display having an optical film set with first and second prism structures disposed on opposing optical films

Backlight for a display having an optical film with first and second prism structures disposed on opposing optical surfaces thereof, or backlight for a display having an optical film set with first and second prism structures disposed on opposing optical films

A backlight module includes at least one optical film and a backlight unit. The optical film has a light incident side and a light emitting side opposite to the light incident side. A plurality of light incident microstructures are formed on the light incident side, and the light incident microstructures are tapered structures. The backlight unit is disposed on the light incident side of the optical film and includes a light source. According to the structural design of the light incident microstructures of the optical film, the light field of the light source can be expanded to achieve the purpose of emitting light at a specific angle. The invention also provides a display device including the backlight module.

Backlight module and display device

A light-emitting mechanism comprises at least one LED, an optical unit disposed on the LED, and at least one dimming unit disposed on the optical unit and corresponding to the LED. The dimming unit includes a shading component disposed directly above the corresponding LED, the size of the shading component is greater than or equal to the size of the LED below the shading component, and the adjacent shading components are not contact with each other. The invention also provides a backlight module including the light-emitting mechanism.
