20090069532 | Polyimide Film - Disclosed herein is a polyimide film having an elongation from 50 to 150%, a tensile elastic modulus from 4 to 8 GPa, a tensile strength from 150 to 500 MPa, and a hygroscopicity of 5% or less. The polyimide film has high elastic modulus and tensile strength and an excellent elongation, and thus the polyimide film exhibits excellent material properties when it is used as a base film for TAB and COF, and its properties can be usefully modified using an additive to improve productivity and processibility thereof. | 03-12-2009 |
20100255221 | POLYIMIDE FILM - Disclosed is a polyimide film, which is colorless and transparent, with superior mechanical properties and high thermal stability. | 10-07-2010 |
20100279131 | POLYIMIDE FILM WITH IMPROVED THERMAL STABILITY - Disclosed is a polyimide film having superior thermal stability, in which the degree of change depending on variation in temperature is minimized. | 11-04-2010 |
20100305298 | CONDUCTIVE MATERIAL AND MANUFACTURING METHOD THEREOF - Disclosed is a method of manufacturing a conductive coating film having superior chemical resistance or solvent resistance and durability by chemically bonding a resin having an amine group (—NH | 12-02-2010 |
20110117498 | PHOTOSENSITIVE RESIN COMPOSITION - Disclosed herein is a photosensitive resin composition which exhibits proper optical density and hydrophobicity when it is formed into a light-shielding film, and which is useful in preventing the color mixing or position deviation of color ink when the color ink is charged in a region defined by a light-shielding film. | 05-19-2011 |
20110311796 | POLYIMIDE FILM - Disclosed is a polyimide film, which is colorless and transparent, and which prevents the distortion of an image and exhibits excellent color reproducibility. | 12-22-2011 |
20120127698 | CONDENSING TYPE OPTICAL SHEET - Disclosed is a condensing type optical sheet for use in a liquid crystal display, which prevents the generation of a yellow band or a rainbow phenomenon without using a protective sheet. | 05-24-2012 |
20130208345 | ELECTROPHORESIS DISPLAY DEVICE AND PREPARATION METHOD OF THE SAME - The present invention relates to an electrophoretic display device that includes: first and second substrates separated from each other by a predetermined distance; first and second electrodes formed on one side of the first and second substrates, respectively, and disposed to face each other; a black pattern layer formed on the first electrode; a plurality of partition walls formed between the first and second electrodes, one side of the partition walls on the first electrode being in contact with or overlapped with the black pattern layer; and a slurry of charged white particles filled between the partition walls. The electrophoretic display device can exhibit a high contrast ratio and enhanced visibility to realize high-quality text. | 08-15-2013 |
