  • Publication number: 20220310030
    Abstract: The present disclosure provides a display substrate, a method for driving same, and a display device, which belong to the field of display technologies. In the display substrate, in a plurality of pixels connected to each shift circuit, the respective pixels sharing the same data line have the same color, and each shift circuit is connected to one turn-on signal terminal. Through flexible control over a turn-on signal provided by the turn-on signal terminal, each data line can continuously provide data signals to the pixels of the same color. In this way, when a pure-color picture is displayed, the number of times of potential reversal on each data line is less, which effectively reduces power consumption of the display device.
