  • Patent number: 7749783
    Abstract: A method of forming a display panel includes providing a first substrate having a transparent electrode, and a second substrate having a pixel electrode. Subsequently, an alignment material is provided and covers on the transparent electrode and/or the pixel electrode, and a photoelectric twisting layer is provided between the first substrate and the second substrate. The alignment material is first in a non-aligned state, and is radiation-polymerizable. The photoelectric twisting layer does not include any radiation-polymerizable material. Thereafter, a voltage difference is applied to drive molecules of the photoelectric twisting layer, and a radiating process is performed on the alignment material. The twisted molecules of the photoelectric twisting layer induce the surface molecules of the alignment material to arrange in an ordered state, and the alignment material is polymerized according to the ordered state as a first alignment film.

  • Publication number: 20070024776
    Abstract: An integrated type optical film with a wire grid polarizer structure and a manufacturing method thereof solves the optical matching problem of conventional optical film and integrates an optical effectiveness with all layers by using non-linear optical theory to redistribute integral polarizing efficiency and transmittance in all layers. The integrated type optical film includes two types of polarizers, a reflective type wire grid polarizer and an absorbing type polarizer. The reflective type wire grid polarizer can reflect an incident polarizing light parallel with a metal grid thereof, and transform and transmit polarizing light perpendicular to the polarizer with secondary transmitting efficiency, so that multi-layered structures are integrated into a polarizer with high polarizing efficiency, high transmittance and light-reflective efficiency.
