Abstract
The present disclosure provides a level shifting unit which includes, for example, a logic control module, an output module, an output control module and a feedback module. The logic control module is connected to a turn-on power supply, a driving power supply, an input signal terminal, and the output module. The feedback module is connected to an enable signal terminal, a signal output terminal, and the output control module. The output control module is connected to the output module and the driving power supply. The output module is connected to the signal output terminal. The feedback module controls to turn on or turn off the output module through the signals outputted from the enable signal terminal and the signal output terminal. If the signals outputted by two level shifting units are short circuited, the feedback module controls the output control module of the level shifting circuit to be disconnected.
