| 20100128203 | LAMP, METHOD FOR MANUFACTURING THE SAME AND LIQUID CRYSTAL DISPLAY APPARATUS HAVING THE SAME - A lamp according to one or more embodiments includes a tube which forms a light-emitting space, an electrode main body which is disposed in the tube, and an emitter surface metal layer which includes an alkali metal oxide and/or an alkaline earth metal oxide, and covers the electrode main body. The emitter surface metal layer may include cesium (Cs) and may further include at least one selected from the group consisting of beryllium oxide (BeO), magnesium oxide (MgO), calcium oxide (CaO), strontium oxide (SrO), barium oxide (BaO), cesium oxide (CsO) and radium oxide (RaO). Therefore, discharge may be easily activated because of a high secondary electron emission coefficient. Thus, a light-emitting efficiency may be enhanced and dark start characteristics may be improved. | 05-27-2010 |
| 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 |
