Display panel control method and device and display equipment

The invention discloses a control method and device of a display panel and display equipment, and belongs to the technical field of display. The control method of the display panel comprises the steps of obtaining an interval type of a current moment, wherein the interval type comprises a display interval and a blank interval; under the condition that the interval type is the display interval, setting a delay interval according to a data control signal, the total duration of the current frame and a preset delay proportion, and reducing the power consumption of the display panel in the delay interval; and under the condition that the interval type is the blank interval, reducing the power consumption of the display panel in the blank interval. A software control function is designed in the data driving chip, and the power consumption of the data driving chip in the corresponding interval is reduced according to the interval type of the display picture, so that the total power consumption of the data driving ch
