Patent number: 9261638Abstract: A flexible light guide film having a light-adjusting structure in the form of a lenticular-like microstructure on the bottom side of the light guide film. The light guide film has a substrate layer supporting a layer light-adjusting structure, which is in the form of an array of longitudinal lenticular lenses laterally arranged in parallel. A prismatic-like microstructure may be provided on the top light emitting side of the light guide film. The light guide film is fabricated by a process involving coating/embossing of a roll of sheet material, in a roll-to-roll continuous process. Advantages includes significantly reducing the thickness of the light guide film, and the roll-to-roll fabrication process provides for more precise replication of the microstructures on the master mold or drum onto the surface of the light guide film, which in turn reduces the failure rate and manufacturing cost.Type: GrantFiled: June 7, 2011Date of Patent: February 16, 2016Assignee: UBRIGHT OPTRONICS CorporationInventors: Kong-Hua Wang, Kai-Jing Wang, Fang-Chun Yeh, Ching-An Yang, Yi-Chun Huang

Patent number: 8899768Abstract: A luminance enhancement film having a built-in light diffusing structure. The support substrate incorporates a dispersion of particles for light diffusion. In accordance with the present invention, a separate particle layer is not required in addition to the support substrate layer. The particles are integrated in the unitary support substrate layer. In one aspect of the present invention, the particles are dispersed near at least one of the planar surfaces of the support substrate (i.e., the light input surface light output surface or both of the support substrate. All the particles may be embedded below the surface of the support substrate, or some of the particles may protrude above the surface of the support substrate. In one embodiment of the present invention, the support substrate contains particles that are dispersed only close to its surface and form protrusions at the surface (i.e., the particle dispersed surface is not smooth).Type: GrantFiled: May 26, 2009Date of Patent: December 2, 2014Assignee: UBright Optronics CorporationInventors: Nan-I Liu, Yeong-Yuan Zuang, Kong-Hua Wang
