Abstract
A display device and a method for driving the same are provided. The display device includes an array substrate and a data driving circuit, the array substrate includes a plurality of data lines divided into multiple groups, each group includes at least two data lines, first ends of the data lines in each group are connected together by the data driving circuit during a first charge sharing phase of each scanning period, the array substrate further includes a plurality of switches; the display device further includes a control circuit configured to output a control signal during a second charge sharing phase of each scanning period, each switch is turned on according to the control signal to connect second ends of corresponding data lines in corresponding group; in each scanning period, the first charge sharing phase and the second charge sharing phase are at least partially overlapped with each other.
