ABSTRACT:
A system status display module with a level-shift circuit thereof is provided for processing signals of system status data. The level-shift circuit includes an input circuit and an output circuit for processing plural input signals that have different voltage ranges. The input circuit includes two field effect transistors (FETs) in circuit connection with an input adjusting voltage, thereby transferring the voltage ranges of the input signals into the operation voltage range of a display controller on the module. The output circuit includes another two FETs in circuit connection with two different output adjusting voltages, thereby transferring the voltage range of an output signal transmitted from the display controller into required voltage ranges for the mother board.
