Abstract: An image driving device includes a determining unit, and image processing unit, and a memory. The determining unit determines whether an input image is a moving image or a still image, and may be synchronized with an internal clock different from an external clock. The image processing unit may image-process at least one frame but less than all frames of the input image when the input image is determined to be a still image. The image processing unit may output the at least one image-processed frame as first image data, and the memory may store the first image data.

Abstract: A display driving circuit and a display device including the display driving circuit are disclosed. The display driving circuit includes: a data driver including a first channel amplifier operating based on first pixel data and a second channel amplifier operating based on second pixel data and configured to drive first and second pixels of a display panel based on the first pixel data and the second pixel data of a first line; and a data comparator configured to compare the first pixel data with the second pixel data and determine operation states of the first channel amplifier and the second channel amplifier on a comparison result, before a first horizontal period in which the first pixel and the second pixel are driven.

Abstract: Provided are a display driver, a display device, and a display system. The display driver includes: an interface configured to receive a control signal and image data from a host, a sum of a number of columns and rows of the image data being less than a sum of a number of columns and rows of the display panel; an image splitter configured to split, based on the control signal, the image data into a plurality of image data respectively corresponding to a plurality of partial regions of the display panel, the plurality of partial regions being separate from each other; a storage configured to store the plurality of image data in a plurality of storage areas respectively corresponding to the plurality of partial regions; and a source driver configured to drive the display panel based on the plurality of image data output from the storage during one frame period.
