A display apparatus includes a display panel and a data driver. The display panel is configured to display an image and includes first through fourth data line groups. The first and second data line groups are adjacent to each other, and the third and fourth data line groups are adjacent to each other. The data driver includes a first data driving circuit configured to output first data voltages to the second data line group later than to the first data line group by a first delay time, and configured to output second data voltages to the fourth data line group later than to the third data line group by a second delay time that is different from the first delay time.

Display apparatus and a method of driving the same

A display device includes a display panel, a timing controller, a data driver, and a light source unit. The display panel includes a plurality of data lines. The timing controller receives a control signal and image data, and outputs a data control signal, converted image data, and a mode selection signal. The data driver receives the data control signal, the converted image data, and the mode selection signal from the timing controller, outputs a data voltage to the plurality of data lines, and operates in a first mode which is a power saving mode or a second mode which is a normal driving mode in response to the mode selection signal. The light source unit includes a light source part that operates in association with a source driving circuit included in the data driver.

Display device with low power consumption

A data driver includes an N-th amplifier including first and second input nodes and a first output node and configured to output an N-th data voltage to an N-th data line, the first input node receiving the N-th data voltage from an N-th node, the second input node being connected to the first output node, a first switch connected between the N-th node and the first input node, and a second switch connected between the first input node and the second input node.

Data driver and a display apparatus including the same

A data driver includes a first latch, a second latch, a digital-to-analog converter, and an output buffer. The first latch sequentially stores first line data in response to a first sampling signal and outputs the stored data in parallel. The second latch sequentially stores second line data in response to a second sampling signal and outputs the stored data in parallel. The digital-to-analog converter converts the parallel data provided from one of the first and second latches to data voltages. The output buffer outputs the data voltages in response to a delay clock.
