    摘要： Provided is a display device for an embodiment in which a central axis of a light guide plate (LGP) and a central axis of one or more light sources are matched with each other to maximize efficiency of the light sources, and which has an ultra-slim structure. The display device may include: a display panel which displays an image; an LGP which guides light to the display panel; light sources which are disposed on a side of the LGP and provide light to the LGP; a circuit board which is disposed on a side of the display panel with the light sources mounted on a surface thereof, and driving chips which drive the display panel mounted on an opposite surface thereof; and a frame which houses the LGP and the light sources and on which the circuit board and the display panel are mounted.

    摘要： A backlight unit assembly, a liquid crystal display having the same, and a dimming method thereof are provided. The dimming method for a liquid crystal display includes setting a plurality of lookup tables, each lookup table having different data for adjusting luminance corresponding to a same grayscale, calculating a grayscale average of a whole liquid crystal display panel and grayscale averages of individual liquid crystal display panel blocks with respect to an image signal input to the liquid crystal display panel, selecting one of the plurality of lookup tables in accordance with the whole grayscale average, and calculating the data for obtaining the luminance corresponding to the individual grayscale averages in the selected lookup table, and adjusting and applying power to a light emitting diode assembly using the calculated data. In the case of displaying an image, which is dark on the whole and only a part of which is bright, power is applied with a wider pulse width at the same grayscale, and thus the image can be displayed with a desired luminance to minimize image distortion.
