摘要:
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.

A liquid crystal display (LCD) may include in accordance with one or more embodiments an LCD panel on which an image is displayed and a fluorescent lamp providing light to the LCD panel. A tube current having a duty ratio may be applied to the fluorescent lamp. The duty ratio of the tube current may increase gradually from an initial duty ratio to a final duty ratio during a transition interval.

A monomer for forming an organic anti-reflective coating layer, a polymer thereof and a composition including the same are disclosed. In a photolithography process, the organic anti-reflective coating layer absorbs an exposed light between a layer to be etched and a photoresist layer, and prevents a photoresist pattern from collapsing due to a standing wave generated under the photoresist layer. The polymer for forming an organic anti-reflective coating layer includes a repeating unit represented by Formula wherein, R1 is a hydrogen atom, a methyl group or an ethyl group, R2 is a C1˜C20 alkylene group, a C3˜C20 cycloalkylene group or a C6˜C20 aromatic hydrocarbon group, POSS is a polyhedral-oligomeric-silsesquioxane, and m is an integer of 2 to 110.
