Abstract: A data driver and a display driving circuit are provided. The display driving circuit includes a first gamma voltage generator that supplies a first gamma voltage set, a second gamma voltage generator that supplies a second gamma voltage set, a first channel driver that outputs a selected one of gamma voltages of the first gamma voltage set, and a second channel driver that outputs a selected one of gamma voltages of the second gamma voltage set. In a first operation mode, the first channel driver and the second channel driver respectively drive a first data line and a second data line of a display panel, and in a second operation mode, the second gamma voltage generator and the second channel driver are disabled, and the first channel driver time-divisionally drives the first data line and the second data line, based on the first gamma voltage set.

Abstract: Disclosed are a display driving circuit and a display apparatus including the same. A display driving circuit includes a first amplifier configured to drive a first data line of a display panel based on first pixel data and a second amplifier configured to drive a second data line of the display panel based on second pixel data, wherein, when a first data difference between the first pixel data and the second pixel data is greater than or equal to a data value indicating one grayscale and is less than or equal to a first threshold value, the second amplifier is turned off, and the first amplifier is configured to drive the first data line and the second data line based on the first pixel data and the second pixel data.

Abstract: A display apparatus includes a display driving circuit and a controller. The display driving circuit includes a data driver to sequentially drive a plurality of pixel groups during one horizontal period in a time-division manner. The pixel groups are included in each of the horizontal lines of a display panel. The controller analyzes a pattern of received image data and determines a driving sequence of the plurality of pixel groups of each horizontal line based on a result of the analysis of the pattern of received image data.
