  • Patent number: 10269288
    Abstract: A display device includes an image processor configured to invert a switch signal at a change of frames, and output, based on the switch signal, one among odd column pixel data and even column pixel data among first through (2M)-th column pixel data included in a frame data, as a half frame data, a display panel including first through M-th odd column pixels coupled to first through M-th odd column lines, respectively, and first through M-th even column pixels coupled to first through M-th even column lines, respectively, and a driving circuit including first through M-th driving units including a K-th driving unit configured to drive, based on the switch signal, one among K-th odd column pixels through a K-th odd column line and K-th even column pixels through a K-th even column line, using a K-th column pixel data included in the half frame data.

  • Patent number: 10199005
    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.

  • Publication number: 20160125843
    Abstract: Provided are a display driver integrated circuit (IC) and an electronic device including the same. The display driver IC includes a control unit for activating a gray mode signal based on an external signal input to the control unit; and a data processing unit for processing input data as gray data in a gray mode, in response to the gray mode signal.
