20100208507 | LUMINESCENCE DEVICE AND METHOD OF MANUFACTURING THE SAME - Provided are a luminescent device and a method of manufacturing the same. The luminescent device includes a charge trapping layer having bistable conductance and negative differential resistance (NDR) characteristics, and an organic luminescent layer electrically connected to the charge trapping layer. | 08-19-2010 |
20110205217 | METHOD OF DRIVING DISPLAY PANEL - Provided is a method of driving a display panel having a charge trap device and an organic light emitting diode (OLED). The charge trap device includes a nanocrystal layer. The nanocrystal layer includes nanocrystals, which are crystallized and dispersed, and a barrier layer, which buries the nanocrystals. When a program voltage is applied, charges are trapped in the nanocrystals, and the OLED emits light at a predetermined luminance with the application of a read voltage. Data signals are sequentially applied to all pixels of the display panel to express desired grayscales. The pixels of the display panel receive the read voltage and emit light at the same time. | 08-25-2011 |

20090326440 | Piezotome for maxillary sinus operation - A piezotome operation unit for lifting a maxillary sinus at a position of placement of an implant upon lifting the maxillary sinus, which forms and enlarges the vertical hole with ease in a remaining bone of the maxillary sinus though vertical approaching, and upon forming a lateral window below a malar bone through lateral approaching, prevents a maxillary membrane from becoming damaged, thereby ensuring continuous, safe lifting so that the operating time is shortened and the efficiency of the operation is maximized. | 12-31-2009 |
20100291511 | METHOD OF MAXILLARY SINUS BONE GRAFTING FOR PLACEMENT OF IMPLANT - A method of maxillary sinus bone grafting for placement of an implant in which upon placement of the implant, a vertical hole is formed and enlarged with ease in a maxillary sinus floor, a maxillary membrane is easily lifted in an always-stable state using a piezotome and gel type bone graft material while preventing the membrane from becoming damaged, and even the bone graft material of coarse bone meal is uniformly diffused and infused, thereby ensuring that the implant is placed in a fast, safe manner while allowing a patient to keep relaxed and alleviating the pain the patient feels, resulting in shortening a curing time and maximizing effects of the placement of the implant. | 11-18-2010 |
