Now user can boot up on a display panel or standby startup operation；When user input enabled instruction, display circuit
The enabled instruction of the receive user of bootrom 11 electrically connected with display floater in 10, and the signal of high level is produced, the height electricity
Ordinary mail number is carried out after current limliting by first resistor 13, then drop-down for relatively low level by second resistance 14, so that the one or three
Pole pipe 16 is turned on；Now, show that the electric current of light current power supply 12 can flow through isolation circuit 20 Jing after 3rd resistor 15 carries out current limliting
Light emitting diode 211, this electric current for flowing through light emitting diode is the first enabling signal.
Due to the power-supply system between display circuit 10 and governor circuit 30 it is different, the first enabling signal Jing isolation circuit
20 are converted to optical signal, then are converted into the second enabling signal by optical signal and transmit to governor circuit 30 so that in governor circuit 30
The 3rd triode 38 turn on, master control light current power supply 40 realizes the arousal function of circuit to electricity on main control chip 32.Wherein,
Six resistance 35 and the 7th resistance 36 are all current-limiting resistance.
Driving chip 31 is detected will produce high level signal after main control chip 32 works, respectively the He of the 4th resistance of Jing 33
8th resistance 39 is carried out after current limliting so that the second triode 37 is turned on, the resistance 34 of Continuity signal Jing the 5th of the second triode 37
After current limliting, the base potential of the 3rd triode 38 is locked, that is, the base stage for controlling the 3rd triode 38 is maintained at the low level of conducting
Signal.Now, display circuit 10 need not provide the first enabling signal, therefore can close the enabling signal of display circuit 10, specifically
Bootrom 11 produce low level so that the cut-off of the first triode, then display light current power supply 12 in display circuit 10 disconnect with
The electrical connection of bootrom, display circuit 10 no longer produces the first enabling signal.It is achieved in the auto-lock function of governor circuit 30.
When driving chip 31 receives the shut-off instruction of user input on the display floater electrically connected with driving chip 31, or
When not receiving any operational order in setting time, high level signal will be set low level, now the 3rd triode 38
Disconnect so that master control light current power supply 40 disconnects the electrical connection with main control chip 32, completes the shutdown of electric equipment or standby, reduce
The power consumption of electric equipment chip.
The present embodiment embodies the detailed process that signal is produced and transmitted in circuit by specific control circuit, so as to show
Circuit wakes up governor circuit work, while after governor circuit work, producing cut-off signals connects display circuit deenergization, with
Reduce the power consumption of circuit.Additionally, governor circuit can also produce the cut-off signal for connecting governor circuit deenergization, so as to realize
The shutdown of electric equipment is standby, further reduces the power consumption of circuit.
