1. A grid-driving-circuit array, wherein the grid-driving-circuit array is applied to a display panel, the display panel is delimited into a plurality of active areas, and each of the active areas comprises multiple rows of pixel units and multiple rows of grid lines; and
the grid-driving-circuit array comprises:
multiple groups of grid driving units, wherein the multiple groups of grid driving units supply grid driving signals to the plurality of active areas, and each of the groups of grid driving units comprises one or more grid driving circuits; and the one or more grid driving circuits are configured for supplying the grid driving signals to the grid lines within the active area corresponding to the one or more grid driving circuits; and
one or more multiplexers, wherein each of the multiplexers comprises a plurality of frame-starting-up-signal outputting units, each of the frame-starting-up-signal outputting units of the multiplexer is configured for supplying a frame starting-up signal to one of the grid driving circuits, and the frame starting-up signals of different grid driving circuits in each of the groups of the grid driving units are supplied by the frame-starting-up-signal outputting units in different multiplexers,
wherein each of the frame-starting-up-signal outputting units in the multiplexer comprises signal gating transistors and subregion gating transistors;
control electrodes of the signal gating transistors in the multiplexer are connected to a same first gating signal line, first electrodes of the signal gating transistors are connected to a same reference-voltage signal line, and second electrodes of the signal gating transistors are individually connected to a frame-starting-up-signal terminal of the grid driving circuit corresponding thereto;
control electrodes of the subregion gating transistors in the multiplexer are individually independently connected to second gating signal lines, and first electrodes of the subregion gating transistors are connected to a same driving-voltage signal line; and
second electrodes of the subregion gating transistors are individually connected to a frame-starting-up-signal terminal of the grid driving circuit corresponding thereto.
