Abstract

According to an embodiment of the present disclosure, a display device includes a liquid crystal display panel; and a backlight unit configured to supply light to the liquid crystal display panel, wherein the backlight unit includes a light source array including a plurality of blocks each including a plurality of light sources, and a light source driver configured to control the plurality of blocks, the plurality of blocks are divided into a plurality of groups, and blocks belonging to a same group are arranged consecutively in a vertical direction.

Claims (17)

1. A display device comprising:

a liquid crystal display panel; and

a backlight unit configured to supply light to the liquid crystal display panel;

wherein the backlight unit includes:

a light source array including a plurality of blocks each including a plurality of light sources, and

a light source driver configured to control the plurality of blocks,

wherein the plurality of blocks are divided into a plurality of groups, and

wherein blocks belonging to a same group are arranged consecutively in a vertical direction,

wherein the light source driver includes a plurality of driving devices, each of the plurality of driving devices corresponding to a respective group of the plurality of groups, and a light source circuit board, on one surface of which the light source array is mounted and on an opposite surface of which the plurality of driving devices are mounted, and

wherein each of the plurality of driving devices is disposed to overlap at least one block of a group excluding the respective group corresponding to the driving device, and to not overlap blocks of the respective group corresponding to the driving device.

2. The display device of claim 1 , wherein the blocks belonging to a same group are arranged such that a number of consecutive blocks in a horizontal direction is fewer than a number of consecutive blocks in the vertical direction.

3. The display device of claim 1 , wherein the blocks belonging to a same group are arranged not to be consecutive in a horizontal direction.

4. The display device of claim 3 , wherein the blocks belonging to the same group are arranged such that a predetermined number or more of blocks are not consecutive in the horizontal direction.
