Classification: CPC B  F | IPC B  F

Claim 5:
6. A headlamp driving device comprising:
a light-emitting cell array comprising a first emission region, a second emission region, and a third emission region; and
an emission control device configured to control the light-emitting cell array, the emission control device comprising:
a plurality of controllers configured to control an on operation and an off operation of each of the first emission region, the second emission region, and the third emission region; and
a plurality of drivers electrically connected to the plurality of controllers and configured to supply a voltage to each of the first emission region, the second emission region, and the third emission region,

wherein a size of a light-emitting cell included in the second emission region is less than a size of a light-emitting cell included in the third emission region, and
wherein the plurality of controllers comprise:
a first controller configured to control an on operation and an off operation of a first group of light-emitting cells of the second emission region;
a second controller configured to control an on operation and an off operation of a second group of light-emitting cells of the second emission region, the second group being different from the first group;
a third controller configured to control an on operation and an off operation of a third group of light-emitting cells of the third emission region; and
a fourth controller configured to control an on operation and an off operation of a fourth group of light-emitting cells of the third emission region, the fourth group being different from the third group.
