  • Method for orientation of liquid crystals in micro/nano region on basis of laser direct writing and system thereof
    Patent number: 10459294
    Abstract: The method for orientation of liquid crystals in a micro/nano region on the basis of laser direct writing and a system thereof includes a laser direct writing system employed to build a micro/nano structure. Liquid crystal molecules in a micro/nano structural region perform self-orientation; and the orientation of liquid crystals is generated by fine structures on side walls of polymer strips which form the micro/nano structure. The dimension of the micro/nano region varies from the micrometer magnitude to the nanometer magnitude exceeding the diffraction limit. The orientating direction can be adjusted and controlled in the micro/nano region, which is favorable for the miniaturization of the liquid crystal display devices and the orientation of the complicated three-dimensional liquid crystal structure.
