摘要： A liquid crystal display includes a liquid crystal panel having display blocks arranged in a first matrix thereon, and light-emitting blocks which provide light to the liquid crystal panel. Each of the light-emitting blocks corresponds to a corresponding column of the first matrix and provides the light to a corresponding column of display blocks in the corresponding column of the first matrix. A frame during which an image is displayed on the liquid crystal display is divided into time slots, and a number of the time slots is equal to a number of the corresponding display blocks included in each column of the first matrix. A luminance of the light provided by each of the light-emitting blocks during each time slot of the frame is controlled based on an image data signal supplied to the corresponding column of the first matrix.

摘要： A light source driving device includes a resolution analyzing part, a dimming block adjusting part, a local dimming part and a light source unit. The resolution analyzing part obtains an image resolution. The dimming block adjusting part adjusts the size or the number of dimming blocks generating light in a local dimming method in response to the resolution. The local dimming part generates a local dimming signal for individually driving the dimming blocks in response to the image data and the size or the number of dimming blocks. The light source unit is driven by the local dimming signal to generate light. The size or the number of the dimming blocks is adjusted to be optimized for the obtained image resolution, so that regardless of the image resolution, a local dimming signal corresponding to the size and the number of the dimming blocks may be generated.
