First, before disk state display device 300 does not come into operation, because the first light emitting diode 320 and second anode tap of light emitting diode 350 and the operating voltage VCC of cathode terminal are high-voltage level, make the first light emitting diode 320 and the second light emitting diode 350 not conductings, also present the first show state and the second show state that extinguish state.
In the time that disk state display device 300 comes into operation, control module 110 for example provides the working signal WS_1 ~ WS_N of high-voltage level, and working signal WS_1 ~ WS_N can be sent to the first light emitting diode 320 via the first impact damper 310.Now, first anode tap of light emitting diode 320 and the operating voltage VCC of cathode terminal are high-voltage level, the first light emitting diode 320 not conductings, and present the first show state that extinguishes state, represent hard disk with the connection status of hard disk backboard for not being connected.
Then,, after hard disk and hard disk backboard couple, connect signal CS_1 ~ CS_N and can be converted to low voltage level, and be sent to the cathode terminal of the first light emitting diode 320.Due to the working signal WS_1 ~ WS_N of the anode tap of the first light emitting diode 320 cathode terminal that is high-voltage level, and the connection signal CS_1 ~ CS_N of the anode tap of the first light emitting diode 320 is low voltage level, therefore the first light emitting diode 320 conductings, and present the first show state of shinny state, to represent hard disk and the hard disk backboard connection status as being connected really.
