Driving method of display device, and display device

A driving method for a display device, the display device comprising a driving chip and a plurality of selectors;

• wherein the driving chip comprises a first pin connected to at least four scan lines through each of the plurality of selectors, and a second pin connected to a respective data line;
• wherein the driving method comprises:
• generating a row initialization signal configured to drive the at least four scan lines connected to each of the plurality of selectors and outputting the row initialization signal to the selector through the first pin of the driving chip;
• and
• controlling, by the selector, a corresponding output terminal of the selector to output the row initialization signal to the corresponding scan line for driving the corresponding scan line, according to a respective control signal;
• wherein the row initialization signal is generated based on original scan signals of the at least four scan lines connected to the selector;
• wherein the row initialization signal comprises at least four scan cycles, each scan cycle being configured to scan one respective scan line;
• wherein the operation of the selector controlling the corresponding output terminal of the selector to output the row initialization signal to the corresponding scan line for driving the corresponding scan line according to the control signal comprises:
• obtaining grayscale voltages of pixels located in a same column respectively corresponding to the at least four scan lines connected to a current selector;
• and
• determining whether the grayscale voltage corresponding to any one of the at least four scan lines represents a black image;
• in response to determining the grayscale voltage corresponding to any one of the at least four scan lines represents a black image, controlling the respective output terminal of the selector corresponding to the scan line to not output a signal so that the corresponding scan line is not driven;
• in response to determining that the grayscale voltage corresponding to each of the at least four scan lines does not represent a black image, controlling, by the selector, the corresponding output terminal of the selector to output the row initialization signal to the corresponding scan line for driving the corresponding scan line according to the respective control signal.
