  • Patent number: 8400395
    Abstract: In a machine-implemented method of local dimming a light source of a light source block for driving the light source block to provide a plurality of image regions with light, duty ratios of a first light source and a second light source adjacent to the first light source are initially determined by using a first target luminance value of a first image region closest to the first light source and a second target luminance value of a second image region closest to the second light source. The initially determined duty ratios are compensated by using a target luminance value of a remaining image region excluding the first and second image regions among the image regions receiving the light generated from the first and second first light sources. The first and second first light sources are driven by using the compensated duty ratios.

  • Patent number: 8362678
    Abstract: 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.

  • Patent number: 8044566
    Abstract: A fluorescent lamp includes a lamp body, a fluorescent layer and a discharge electrode. The lamp body has a discharge space in which ultraviolet light is generated. The fluorescent layer is formed on an inner surface of the lamp body to change the ultraviolet light into visible light. The discharge electrode is on an end portion of the lamp body to apply a voltage to the discharge space. A ratio of intensities of the visible light at wavelengths of about 545 nm and about 516 nm is about 1.32:1 to about 1.71:1. Therefore, color reproducibility and luminance may be improved.
