As shown in the figure, the difference between the hard disk running state display control device 1' and the above-mentioned hard disk running state display control device 1 is that the hard disk running state display control device 1' adopts the output port 2 that can provide the hard disk running state. The power supply terminal 11' of the 5V power supply with a high potential (3.3V) electric signal potential, so that the reverse diode can be activated when the hard disk is in the running state and the hard disk running state output port 2 outputs a low potential electric signal. 13' is turned on, so that the potential of the branch contact a1' is pulled down, and then the light-emitting diode 15' is turned on, so that the display lamp 15' is turned on. At this time, because the light-emitting diode 15' is electrically connected to the supply Compared with the power supply terminal 11 of 3.3V in the above-mentioned hard disk operating state display control device 1, the power supply terminal 11' of the 5V power supply increases the voltage, so that the current flowing through the light emitting diode 15' is correspondingly strengthened, thereby enhancing the power of the light emitting diode 15'. '; but, when the output port 2 of the hard disk running state outputs a high-potential electrical signal, since the potential of the high-potential electrical signal is 3.3V, and the anode of the reverse diode 13' is electrically connected to the available The power supply terminal 11' of the 5V power supply causes the reverse diode 13' which should be cut off to be turned on, so that the voltage value of the branch contact a1' is lower than 5V, and thus the potential of the branch contact a1' cannot be pulled up to The same potential (5V) as the anode terminal of the light-emitting diode 15' may make the light-emitting diode 15' conduction, so that the display lamp 15' is still on when the hard disk is in a non-running state, causing the display lamp to erroneously display. Actions occur, causing the user to be unable to correctly and intuitively understand the operating status information of the hard disk through the display light 15'
