1. A drive apparatus, comprising:
a first controller configured to generate and output a data control synchronization signal after being energized, wherein the data control synchronization signal is configured to control whether to load a data voltage onto a data line in a touch display panel to be connected; and
a second controller connected with the first controller, and the second controller is configured to directly output a first set level signal and a second set level signal before being energized;
wherein the first set level signal is configured to control a selection of a display drive mode from a plurality of drive modes supported by the touch display panel to be connected; and
the second set level signal is configured to control a output of a drive signal corresponding to the display drive mode for the touch display panel to be connected.
