DISPLAY DEVICE

摘要

The present invention relates to a display device. The display device includes a backlight unit (BLU) split into a plurality of blocks and driven by each block, the BLU including a plurality of optical assemblies; a display panel disposed above the BLU; a control unit outputting a local dimming value for each block corresponding to the brightness of each of the blocks of the BLU according to an image displayed on the display panel; and a BLU driving unit controlling the brightness of each of the blocks of the BLU using the local dimming value for each block. Each of the optical assemblies includes a substrate; a plurality of light sources disposed on the substrate to emit light; and a light incident part having a light incident surface in which light emitted from the light sources is laterally incident; and a light guide plate including a light emitting part in which the incident light is emitted upward. Two optical assemblies adjacent to each other, of the plurality of optical assemblies, partially overlap each other. The BLU driving unit receives the local dimming value for each block to output a plurality of driving signals. Each of the plurality of driving signals controls the brightness of two or more blocks of the BLU.
