报告内容摘要:

A new method of improving the surface anchoring of vertical alignment (VA) liquid crystal devices using surface polymer stabilization is introduced. A minute amount of a reactive monomer and photo-initiator is mixed with a nematic liquid crystal host and the mixture is polymerized under UV light to form sub-micron sized polymer protrusions on the two substrates of the cell with an applied bias voltage. Several kinds of reactive monomers with different molecular structures are tested, and an enhanced surface anchoring is achieved. This finding will be useful for display applications.
