| 20110008551 | OPTICAL SHEET - The present invention relates to an optical sheet for use in a liquid crystal display. The optical sheet of the present invention allows for ease of handling, reduces defective proportions and manufacturing costs, improves throughput, and prevents the deterioration of luminance attributable to the damage of the optical sheet. | 01-13-2011 |
| 20110051247 | OPTICAL SHEETS - Disclosed is an optical sheet having a structured surface and a composition for forming optical three-dimensional patterns able to form the structured surface, which is not easily damaged by external force or a rough surface and thus facilitates the handling thereof, reduces defective rates to thus decrease the production cost and increase the production efficiency, and prevents a decrease in luminance attributable to damage. | 03-03-2011 |

| 20090311554 | CARBON NANOTUBE DISPERSING AGENT, CARBON NANOTUBE COMPOSITE, CARBON NANOTUBE FILM, AND METHOD FOR MANUFACTURING THE CARBON NANOTUBE FILM - Provided are a carbon nanotube dispersing agent, a carbon nanotube composite, a carbon nanotube film, and a method for manufacturing the carbon nanotube film. The carbon nanotube dispersing agent has at least one chromophore including at least one aromatic carbon ring, and has a plane structure. | 12-17-2009 |
| 20100054507 | FILM SPEAKER - A film speaker is provided. The film speaker includes: a piezoelectric film oscillating by receiving a voltage corresponding to a sound signal from a sound signal supply unit; a plurality of carbon nanotube films formed on both sides of the piezoelectric film; and a plurality of electrodes connected to the plurality of carbon nanotube films, receiving the voltage corresponding to the sound signal from the sound signal supply unit, and applying the voltage to the plurality of carbon nanotube films. | 03-04-2010 |
| 20100221531 | CARBON NANOTUBE CONDUCTIVE LAYER USING SPRAY COATING AND PREPARING METHOD THEREOF - Provided is a carbon nanotube (CNT) transparent conductive layer having a loop pattern in which a plurality of loops are at least partially connected to one another, and a fabrication method thereof. The loops in the pattern are generated by a spray-coating method and partially connected with one anther, and thus improving transparency and conductivity of the CNT transparent conductive layer. In Addition, the CNT transparent conductive layer has conductivity and sheet resistance highly suitable for a transparent electrode. | 09-02-2010 |
