  • Patent number: 7812915
    Abstract: A method of fabricating a liquid crystal display includes aligning a mask on a substrate, applying surface treatment to the substrate using light that has passed through the mask, forming a spacer pattern at the surface treated area, and forming a spacer by hardening the spacer pattern. Surface treatment is applied to the area where a spacer is to be formed by an ion beam, ultraviolet radiation or a laser beam. By forming the spacer at the surface treated area using an ink jet, it is possible to control the shape and height of the spacer. Also, since the ink jet is located at the surface treated area, it become easier to align the ink jet to accurately form the spacer at the desired place.

  • Patent number: 7742664
    Abstract: Liquid crystal waveguides for dynamically controlling the refraction of light. Generally, liquid crystal materials may be disposed within a waveguide in a cladding proximate or adjacent to a core layer of the waveguide. In one example, portions of the liquid crystal material can be induced to form refractive or lens shapes in the cladding that interact with a portion (e.g. evanescent) of light in the waveguide so as to permit electronic control of the refraction/bending, focusing, or defocusing of light as it travels through the waveguide. In one example, a waveguide may be formed using one or more patterned or shaped electrodes that induce formation of such refractive or lens shapes of liquid crystal material, or alternatively, an alignment layer may have one or more regions that define such refractive or lens shapes to induce formation of refractive or lens shapes of the liquid crystal material.
