Abstract: A display device, which fixes the magnitude of a driving current flowing through light-emitting devices in a low luminance region and controls an application period of the driving current, includes: light-emitting devices; a processor for controlling the light-emitting devices on the basis of a gray level required for the light-emitting devices in each unit frame; and a timing controller which divides the unit frame into a plurality of sub-frames and generates a scan signal corresponding to each sub-frame. The processor: when the gray level is greater than or equal to a preset value, determines a luminance value of the light-emitting devices on the basis of the gray level and turns on the light-emitting devices with the determined luminance value in all of the plurality of sub-frames; when the gray level is less than the preset value, determines a light-emitting period of the light-emitting devices on the basis of the gray level and divides, on the basis of the light-emitting period, the plurality of sub-frames into a first and a second sub-frame group; turns on the light-emitting devices with a preset luminance value in all sub-frames belonging to the first sub-frame group; and turns off the light-emitting devices in sub-frames belonging to the second sub-frame group or turns on the light-emitting devices with a luminance value less than the preset luminance value.
