20130021568 | REACTIVE MONOMER OF LIQUID CRYSTAL AND LIQUID CRYSTAL PANEL - The present invention discloses a reactive monomer of liquid crystal. The reactive monomer of liquid crystal is added with at least one fluoro group. Because hydrocarbon bonds of a side chain of polyimide surface of an alignment film has a fluorophobic effect, the fluoro group of the reactive monomer of liquid crystal can lower the interaction between the polyimide surface of the alignment film and the reactive monomer of liquid crystal to thus evenly deposit the liquid crystal composition containing the reactive monomers of liquid crystal onto the polyimide surface of the alignment film. Thus, it can avoid from occurring the phenomenon of drop Mura defect occurred during implementing the ODF technology. | 01-24-2013 |
20130100387 | LIQUID CRYSTAL PANEL AND ALIGNMENT FILM THEREOF - The present invention provides a liquid crystal panel and an alignment film thereof, and the alignment film is made of a modified polyimide which has conjugated double bond at side chain. Resistance value of the alignment film is less than the resistance value of a liquid crystal material of the liquid crystal panel by properties of the conjugated double bond that can reduce the resistance value of a prior art polyimide. In addition, improving the imidization ratio of a modified polyimide alignment film is important. The present invention is conducted the charged ion from liquid crystal layer to the alignment film by the conjugated double bond of the modified polyimide at the side chain to prevent the increase in the ion density of the liquid crystal in part of this area, and improve the problem of image sticking. | 04-25-2013 |

20130337196 | LIQUID CRYSTAL MOLECULE HAVING FIVE-MEMBERED RING STRUCTURE AND MIXTURE FOR THE SAME - The present invention discloses a liquid crystal (LC) molecule having a five-membered ring structure and a mixture thereof. A traditional LC molecule is modified into the LC molecule having the five-membered ring structure. The rotational viscosity of the LC molecule within an LC panel is decreased by properties of the five-membered ring structure, so that the LC molecule having the five-membered ring structure has a fast off-time than that of the traditional LC molecule. The present invention can decrease the rotational viscosity of the LC molecule within the LC panel by modification of the five-membered ring structure of the LC molecule, and thus the problem of cross-talk effect produced from switching a two-dimensional mode to a three-dimensional mode in an LC display can be improved. | 12-19-2013 |

A traditional LC molecule is modified into the LC molecule having the flexible structure. The wetting ability of the LC molecule within a color-filter-on-array (COA) type LC panel is increased by properties of the flexible structure, so that the LC molecule having the flexible structure can obtain better diffusing performance than that of the traditional LC molecule. The present invention can increase the wetting ability of the LC molecule within an LC panel by modification of the flexible structure of the LC molecule, and thus the problem of drop Mura effect in the COA type LC panel can be improved. | 12-26-2013 |
