  • Patent number: 10007049
    Abstract: Disclosed herein is a quantum rod backlight module for a liquid crystal display. The quantum rod backlight module includes a quantum rod layer disposing at one side of a backlight source and comprising a plurality of quantum rods, wherein the major axes of the plurality of quantum rods are aligned along a direction parallel to a surface of the quantum rod layer; a first micro-prism layer including a plurality of first parallel strip-shape prisms, and a second micro-prism layer including a plurality of second parallel strip-shape prisms, wherein both of the alignment directions of the first parallel strip-shape prisms and the second parallel strip-shape prisms are perpendicular to the direction of the major axes of the plurality of quantum rods, and the retardations of the first micro-prism layer and the second micro-prism layer are zero.

  • Publication number: 20120067506
    Abstract: A film processing equipment and a method for processing a film is provided. A feeding roller feeds the film to a swelling bath and the swelling bath immerses the film. A dyeing bath dyes the film transferred from the swelling bath and a stretching bath stretches the film. The stretching bath comprises three sets of rollers dividing a film transferring path into a first interval length and a second interval length. The first interval length is in an upstream with respect to the film transferring path and smaller than the second interval length. A crosslinking bath performs a crosslinking process on the film transferred from the stretching bath and a washing bath washes the film. A film attaching assembly performs a film attaching process on the film transferred from the washing bath and a winding device winds the film transferred from the film attaching assembly.
