| 20090290114 | DISPLAY SUBSTRATE AND DISPLAY PANEL HAVING THE SAME - A first slit pattern is formed in a display substrate and a display panel of vertical alignment mode having the display substrate. The first slit pattern includes slits, a pair of projections and a pair of notches. A divergence point where the slits meet each other and an incision portion of the slits have the same function as the pair of projections in the generation of a singular point of liquid crystal. A contact hole exposing a part of an output electrode of a switching element is formed at a protective layer of an array substrate. A step recess is formed at a protective layer corresponding to a storage electrode, a divergence point of the slits is arranged to correspond to the storage electrode. The singular point of the liquid crystal is induced to occur at a regular position, and thus afterimages and spots can be prevented. | 11-26-2009 |

| 20120090546 | SOURCE SUPPLYING UNIT, METHOD FOR SUPPLYING SOURCE, AND THIN FILM DEPOSITING APPARATUS - Provided are a source supplying unit and a method for supplying a source. The source supplying unit includes a pot configured to store a source material, an injector communicating with the pot to inject the source material evaporated from the pot, a high frequency coil part surrounding an outside of the pot, and a resistance-type heating part disposed at an outside of the injector. Since a high frequency induction heating method and a resistance-type heating method are combined to evaporate a source material to be supplied, a large amount of source material can be used, and the thickness and quality of a thin film can be easily controlled. | 04-19-2012 |

| 20090295841 | METHOD OF BOOSTING A LOCAL DIMMING SIGNAL, BOOSTING DRIVE CIRCUIT FOR PERFORMING THE METHOD, AND DISPLAY APPARATUS HAVING THE BOOSTING DRIVE CIRCUIT - There is provided a method of boosting a local dimming signal. In the method, it is determined whether or not local dimming signals, which are applied for individually driving light source blocks per frame, satisfy boosting conditions. Then, a predetermined local dimming signal corresponding to at least one of the light source blocks is boosted to a reference luminance value when the local dimming signals continuously satisfy the boosting conditions, and the boosting luminance of the predetermined local dimming signal at the reference luminance value is gradually decreased after a light adaptation time of an observer's eye. When the luminance of light source blocks that are boosted is gradually decreased before the light adaptation time or luminance of light source blocks that will be boosted is gradually increased to the light adaptation time, power consumption required to boost the light source blocks may be decreased. | 12-03-2009 |

| 20090108545 | SPIN CHUCK - The present invention is directed to a spin chuck for use in a process, such as a cleaning process and an etching process, performed while rotating a substrate. The spin chuck includes a spin head on which a substrate is placed, a driving part configured to rotate the spin head, and a fix bracket installed on the spin head and having a contact surface that is in contact with a flat surface of a flat zone of the substrate at a position corresponding to the flat zone to prevent a vortex caused by the flat zone. Since the fix bracket has the same shape as the flat zone of the substrate, an air current unbalance resulting from the flat zone is suppressed to uniformly inject etchants to a rear surface of the substrate. | 04-30-2009 |
