Driving circuit, driving method, display device and display control method

A driving circuit, comprising multi-stage driving units and an on/off control circuit;

• wherein
• each of the multi-stage driving units comprises an input end and a driving signal output end, and configured for outputting, according to an input signal provided by the input end, a corresponding driving signal via the driving signal output end;
• an input end of a first-stage driving unit of the multi-stage driving units is electrically connected to a start signal end;
• the on/off control circuit is electrically connected to an on/off control end and the input ends of the multi-stage driving units, and configured for controlling, under the control of an on/off control signal provided by the on/off control end, electric connection or electric disconnection of the input ends of the multi-stage driving units, to control the multi-stage driving units to output valid driving signals in a first half of a frame time, and control the multi-stage driving units to output the valid driving signals in turn in a second half of the frame time;
• the driving circuit comprises N-stage driving units, the N being a positive integer greater than 1;
• wherein the on/off control circuit comprises N−1 on/off control transistors;
• a control electrode of an nth on/off control transistor is electrically connected to the on/off control end, a first electrode of the nth on/off control transistor is electrically connected to an input end of an nth-stage driving unit, and a second electrode of the nth on/off control transistor is electrically connected to an input end of an (n+1)th stage driving unit;
• and
• the n+1 is less than or equal to the N, and the n is a positive integer.
