A multi-view pixel directional backlight module and a naked-eye 3D display device are provided. The multi-view pixel directional backlight module includes at least two rectangular light guide plates closely stacked together. A light-emerging surface of the rectangular light guide plate is provided with multiple pixel arrays. Light emitted by pixels in a same pixel array is pointed to a same viewing angle, and different pixel arrays have different viewing angles. At least one side of each rectangular light guide plate is provided with a light source group. Light emitted by the light source group enters the corresponding light guide plate, then emerges from pixels of respective pixel arrays on the light-emerging surface of the light guide plate, and is totally reflected at positions other than positions of the pixels within the light guide plate. Each of the pixels is a nano-diffraction grating.

A method for making a color image and a color filter manufactured with the method. The color of the color image and the color of the color filter are characterized by resonance features of a Fabry-Perot resonant cavity (). Through a nanoimprint technology, Fabry-Perot resonant cavities with different thicknesses are manufactured, and the Fabry-Perot resonant cavities with different thicknesses correspond to red, green and blue respectively. The red, green and blue Fabry-Perot resonant cavities are distributed according to the color separation principle, and a combination thereof has the effect of representing a whole image macroscopically.

A colored, dynamic, and amplified security film includes a micro lens array layer, a base material layer, and a micro graphic layer. The layers meet the condition of Moore amplified imaging; the micro graphic layer is formed by a background area and a graphic area; the graphic area is distributed in the background area; the micro graphic layer includes a semi-transparent and semi-reflective metal layer, a medium layer, and a metal film layer successively from top to bottom; the metal film layer is of a planar structure; the thickness of the medium layer in the graphic area is greater than the thickness of the medium layer in the background area; and the thicknesses of semi-transparent and semi-reflective metal layers are consistent.

An apparatus for manufacturing a light guide film may comprise a feed roller, a receiving roller, a separating device, a hot press printing device and a recombining device. Firstly, the separating device may separate a protective layer from a substrate layer of the light guide film. Secondly, a surface of the substrate layer to be manufactured may be impressed with light guide dots by the hot press printing device, and the recombining device recombine the peeled protective layer to the substrate layer. And lastly, the finished light guide film is recycled by the receiving roller. The apparatus may have advantages such as high output and low cost, and it may manufacture a large dimensioned product.
