| 20080261196 | NAPHTHALENE DIIMIDE-ZN(II) COMPLEX HAVING SELECTIVITY FOR PYROPHOSPHATE, PREPARATION METHOD THEREOF AND DETECTING METHOD OF PYROPHOSPHATE USING THE SAME - The present invention provides a novel fluorescent chemosensor including a naphthalene diimide-Zn(II) complex, which can efficiently recognize pyrophosphate (PPi) at pH 7.4. The fluorescent chemosensor exhibits a new kind of excimer fluorescence, which is selective for PPi in 100% aqueous solution. Further, since the naphthalene diimide-Zn(II) complex of the present invention does not couple with inorganic phosphate (Pi) or adenosine triphosphate (ATP) and has high selectivity for PPi, it can be usefully used to detect pyrophosphate (PPi), which serves to transfer signals and store energy in living organisms. | 10-23-2008 |

| 20090310063 | METHOD OF DRIVING A LIGHT SOURCE, BACKLIGHT ASSEMBLY FOR PERFORMING THE METHOD AND DISPLAY APPARATUS HAVING THE BACKLIGHT ASSEMBLY - In a method of driving a light source, initial driving signals are applied to a plurality of color light sources in response to a power-on signal from an external device. During a predetermined set time period, light amount control signals for controlling an amount of light generated by the color light sources are generated using a predetermined function with reference signals and first sensing signals generating by sensing the amount of the light generated by the color light sources driven by the initial driving signals. Then, compensated driving signals, which are compensated based on the light amount control signal, are applied to the color light sources to compensate the amount of the light generated by the color light sources. | 12-17-2009 |

| 20100123741 | METHOD OF DRIVING A LIGHT SOURCE, LIGHT SOURCE APPARATUS FOR PERFORMING THE METHOD AND DISPLAY APPARATUS HAVING THE LIGHT SOURCE APPARATUS - A method of driving a light source in a normal mode and an increased luminance mode, based on a gradation data of an image signal, by using driving blocks each having a plurality of light-emitting blocks, includes applying, during the increased luminance mode, both a first driving voltage which drives a first driving block of the driving blocks during the normal mode, and a second driving voltage which drives a second driving block of the driving blocks during the normal mode, to the first driving block to increase a luminance of the first driving block when the first driving block is driven by a luminance greater than a luminance corresponding to the gradation data of the image signal. | 05-20-2010 |
| 20100290246 | LIGHT-EMITTING MODULE AND DISPLAY DEVICE HAVING THE SAME - A light-emitting module includes a light guide plate and a light source unit in accordance with an embodiment. The light guide plate include an upper surface, a lower surface facing the upper surface, a plurality of side surfaces connecting the upper surface and the lower surface, and a cross-sectional surface connected to at least one of the side surfaces. The light source unit includes a substrate disposed in correspondence with the cross-sectional surface and a point light source mounted on the substrate to emit light to the cross-sectional surface. Thus, light-emitting efficiency may be enhanced and the arrangement of point light sources may be optimized, so that a required amount of emitted light may be obtained using a small number of the point light sources. In addition, uniformity of luminance and heat-radiating efficiency may also be enhanced. | 11-18-2010 |
