  • Patent number: 9170445
    Abstract: Disclosed are a flexible liquid crystal display (LCD) device and a method of manufacturing the same. The flexible LCD device comprises a first flexible substrate and a second flexible substrate. A layer is disposed on the first flexible substrate and first pixel control lines are disposed on the second flexible substrate. The LCD device also includes polymer walls disposed between the first flexible substrate and the second flexible substrate that maintain a cell gap between the first flexible substrate and the second flexible substrate. The polymer walls are substantially aligned with the first pixel control lines and light transparent gaps in the layer disposed on the first flexible substrate.

  • Patent number: 7067566
    Abstract: Triazine ring based polymers for photoinduced liquid crystal alignment introduces photoactive groups for inducing, reinforcing, improving and preserving liquid crystal alignment, for example photoreactor such as cinnamate, coumarin, chalcone and maleimide, as a chain to have at least one photoactive group. One of the photoactive groups can experience Fries rearrangement which induces liquid crystal alignment, and other groups can experience photodimerization, photoisomerization, photocrosslinkng or photodegradation to reinforce, change or preserve the generated alignment.

  • Publication number: 20050266249
    Abstract: The present invention relates to a flexible metal clad laminate film and a manufacturing method for the same. The flexible metal clad laminate film of the present invention comprises a metal thin film; and a flexible insulating film formed by photo-crosslinking reaction of photoactive polymers having photoactive side chains, which may be crosslinked by photo-irradiation. The flexible metal clad laminate film of the present invention has good physical properties such as size stability, and is almost not deflected or twisted, since it includes the flexible insulating film composed of crosslinked resin formed by photo-crosslinking reaction of photoactive polymer.
