Display device and control method thereof

摘要

A display device for sequentially displaying a plurality of subframes (images) within one frame period according to an image source signal, the device including: a pixel array including a plurality of pixels; a scale factor generator configured to separately calculate electric current values of the electric to be consumed by each of the plurality of respective subframes (per frame period), and to calculate an initial scale factor by comparing the electric current value with a threshold electric current value, and to generate a correction scale factor (for each among the plurality of subframes) of the first frame by using the initial scale factor and a correction scale factor of a previous frame (previous to the first frame) (and of the same subframe index) corresponding to the initial scale factor; and an image processor configured to convert a gray data of the image source signal of the first frame.

1. A display device for displaying a plurality of subframes within one frame period according to an image source signal, the device comprising:
a pixel array including a plurality of pixels; each of the pixels configured to display during the one frame period a plurality of images, each image of the plurality of images being displayed during a respective subframe in the one frame period; wherein each image of the plurality of images are arranged in the image source signal during the one frame period, a scale factor generator configured to: separately calculate electric current values to be consumed during the respective subframes displayed within the 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 one frame period by using the correction scale factors.
