    摘要: A light source package includes a first light source configured to emit first light, an imaginary central axis of the first light extending in a first direction. The light source package may further include a second light source configured to emit second light, an imaginary central axis of the second light extending in a second direction that is different from the first direction. The light source package may further include a first optical part including a first surface that is configured to reflect at least a first portion of the first light. The light source package may further include a second optical part configured to spread the second light. The light source package may advantageously enable illuminating a desirably large display area with a minimum number of light sources and/or optical parts.

    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.
