Display device and control method thereof

A control method of a display device, comprising:

• separately calculating electric current values of the electric current to be consumed in a pixel array by each of a plurality of subframes to be displayed within a frame period according to an image source signal during the frame period;
• wherein the pixel array includes a plurality of pixels;
• each of the pixels configured to display during the frame period a plurality of images, each image of the plurality of images being displayed during a respective subframe in the frame period;
• wherein each image of the plurality of images are arranged in the image source signal during the frame period,
• separately calculating initial scale factors that correspond to the respective subframes by comparing each of the electric current values with a threshold electric current value respectively;
• separately generating correction scale factors that correspond to the respective subframes by using the initial scale factor that corresponds to the respective subframes and a correction scale factor that corresponds to the respective subframes of a previous frame;
• and
• separately changing a gray data of each of the images arranged in the image source signal during the frame period by using the correction scale factors.

A display device for displaying a plurality of subframes within a frame period according to an image source signal, the device comprising:

• a pixel array including a plurality of pixels;
• each of the pixels displaying during a first frame period and a second frame period a plurality of images, each image of the plurality of images being displayed during a respective subframe in the first frame period and the second frame period;
• wherein each image of the plurality of images are arranged in the image source signal during the first frame period and the second frame period,
• a scale factor generator configured to:
• separately calculate electric current values to be consumed during respective subframes displayed within one frame period to correspond to each of the subframes,
• separately calculate initial scale factors that correspond to the respective subframes by comparing each of the electric current values with a threshold electric current value respectively, and
• separately generate correction scale factors that correspond to the respective subframes by using the initial scale factor that corresponds to the respective subframes and a correction scale factor that corresponds to the respective subframes of a previous frame;
• and
• an image processor configured to separately change a gray data of each of the images arranged in the image source signal during the first frame period and the second frame period by using the correction scale factors.
