A backlight module including a substrate, a light source, a porous optical film, and a wavelength conversion optical layer is provided. The light source is located on the substrate. The porous optical film is disposed over the light source and has a plurality of emission structures, and the porous optical film distributes light generated by the light source to be emitted through the emission structures located at different positions of the porous optical film. The porous optical film has a central region and a peripheral region surrounding the central region, the central region is disposed corresponding to the light source, and an area of the central portion is A. The wavelength conversion optical layer is located between the light source and the porous optical film, and a vertical projection area of the wavelength conversion optical film is B, where 0.49&#x2264;A/B&#x2264;5.

Backlight module with porous optical film and a wavelength conversion layer disposed above a light source where the optical film has a plurality of light emission structures

A backlight module including a carrier plate, a plurality of light sources, at least one low reflective portion, and a modulation film is provided. The carrier plate has a carrier surface carrying the light sources while the low reflective portion is disposed on the carrier surface between an outer light source and a side edge of the carrier plate. The reflectance of the low reflective portion is less than that of the carrier surface. The modulation film is disposed above the light sources while the low reflective portion has a projection area on the modulation film. The projection area has a lower normalized transmission ratio comparing to adjacent areas along an extending direction of the side edge of the carrier plate.

Backlight module with light uniform design

The present invention provides a backlight module, comprising a light source module and an optical control layer disposed on the light source module. The optical control layer comprises a first optical film and a second optical film. The first optical film has a first overlap area on a first side, the first overlap area comprises first inner openings; the second optical film comprises a second overlap area near the first overlap area. The second overlap area matches the first overlap area. The second overlap area comprises second outer openings corresponding to the first inner openings.
