摘要： A display device includes: a display panel, a data driver, and a scan driver. The data driver outputs data signals during a writing frame and outputs a bias voltage during a holding frame. The data driver includes a plurality of driving chips, and each of the driving chips includes: a gamma voltage generator, a data converter, a main output part for outputting corresponding data signals of the data signals during the writing frame, and a sub-output part for outputting the bias voltage during the holding frame. The gamma voltage generator of a selected driving chip among the plurality of driving chips is electrically connected to the sub-output parts disposed in the plurality of driving chips, respectively.
