1. A driving method of a display panel, comprising:
entering into, when receiving a display mode switching startup instruction, a non-counting state, driving the display panel to display a first set picture that is pre-stored, and switching a current display mode to a target display mode; and
entering into a counting state when receiving a data mode switching completing instruction, wherein the data mode switching completing instruction indicates switching from a data sending mode corresponding to the current display mode to a data sending mode corresponding to the target display mode has been completed;
wherein the counting-state indicates display data counting being performed, and the non-counting state indicates display data counting not being performed;
wherein after entering into the counting state, the driving method further comprises:
receiving display data;
counting a first number of corresponding set targets in the display data; and
driving the display panel to display a corresponding picture according to the received display data on the basis of the target display mode after determining that the first number is same as a set number corresponding to the target display mode;
wherein the display panel comprises a first display mode; wherein the first display mode comprises:
in a first display frame of two adjacent display frames:
gate lines in the display panel are driven row by row, and
during driving of gate lines connected with display sub-pixels at a next odd row after driving of gate lines connected with display sub-pixels at a previous odd row, a data voltage corresponding to display data is input to data lines corresponding to the display sub-pixels at the next odd row; and
in a second display frame of the two adjacent display frames:
the gate lines in the display panel are driven row by row, and
during driving of gate lines connected with display sub-pixels at a next even row after driving of gate lines connected with display sub-pixels at a previous even row, a data voltage corresponding to the display data is input to data lines corresponding to the display sub-pixels at the next even row;
wherein the display panel comprises a second display mode; wherein the second display mode comprises:
in each display frame:
the gate lines are driven row by row, and
during driving of a next row of gate lines after driving of a previous row of gate lines, a data voltage corresponding to the display data is input to data lines corresponding to sub-pixels connected with the next row of gate lines;
wherein the display panel comprises a third display mode; wherein the third display mode comprises:
in each display frame:
at least two adjacent rows of gate lines are grouped as one of gate line groups, display data corresponding to one row of sub-pixels in each gate line group is received, according to the received display data, gate lines in a same gate line group are driven at same time, and the gate line groups are driven one by one, and
during driving of gate lines in a next gate line group after driving of gate lines in a previous gate line group, a data voltage corresponding to the display data is input to data lines corresponding to sub-pixels connected with the gate lines of the next gate line group;
wherein:
the current display mode is one of the first display mode, the second display mode and the third display mode; and the target display mode is one of the first display mode, the second display mode and the third display mode other than the current display mode;
wherein the set targets comprise sub-pixel rows of the display panel;
the display panel comprises display sub-pixel rows and dummy sub-pixel rows;
when the target display mode is the first display mode, the set number comprises a total number of all the dummy sub-pixel rows and a half of a total number of the display sub-pixel rows; and
when the target display mode is the second display mode, the set number comprises the total number of all the dummy sub-pixel rows and the total number of all the display sub-pixel rows.
