In this embodiment, the television standby power control circuit is suitable for television standby control. In the initial state, the television can be controlled by remote control or keys to turn on the switch circuit 20 to control the output of the CPU power supply VCC to realize ac power-on. When the television enters the standby state from the power-on state, the CPU sends a low level standby signal, and when the standby trigger circuit 30 detects the low level standby signal sent by the CPU40, the bistable trigger circuit 10 triggers and outputs a first level signal. It is understood that the first level signal output by the bistable flip-flop circuit 10 can be set according to actual needs, and in this embodiment, specifically, when the standby flip-flop circuit 20 receives a low level standby signal, the bistable flip-flop circuit 10 outputs the first level signal as a low level signal. When the controlled terminal of the switch circuit 20 receives the first level signal, the switch circuit 20 is turned off, so as to cut off the output of the CPU power supply VCC. Because the power supply VCC of the CPU is cut off to output the electric energy to the CPU40 under the standby condition of the television, the consumption of the electric energy during the standby control is reduced, the energy is saved, and the television is green and environment-friendly.
Further, the television standby power control circuit further includes a key power-on trigger circuit 50 for triggering and outputting a high-level power-on signal of the television, wherein the key power-on trigger circuit 50 is connected to the input end of the bistable trigger circuit 10; the key startup trigger circuit 50 is configured to control level inversion of a first level signal output by the bistable trigger circuit 10 when a high level startup signal of the television is triggered and output; the switch circuit 20 is further configured to be turned on when receiving the first level signal with the inverted level, and control the output of the CPU power supply VCC.

The key start-up trigger circuit 50 is mainly used for controlling the CPU power supply VCC to be turned on when the television is in standby and the CPU power supply VCC is turned off. It can be understood that, since the CPU power supply VCC is turned off, the television cannot be controlled to be turned on by a wireless signal, for example, by remote control, the key-on trigger circuit 50 is provided, when the key-on trigger circuit 50 triggers and outputs a high-level power signal of the television, the key-on trigger circuit 50 controls the bistable trigger circuit 10 to output a first level signal to flip, the output first level signal is converted from a low level to a high level, the switch circuit 20 is turned on to control the CPU power supply VCC to output, thereby making up the situation that the television cannot be turned on by remote control when the CPU power supply VCC is turned off in standby.
In this embodiment, the bistable flip-flop circuit 10 includes a first transistor Q1, a second transistor Q2, a first resistor R1, a second resistor R2, a third resistor R3, and a fourth resistor R4; the emitter of the first triode Q1 is grounded, the collector of the first triode Q1 is connected with the CPU power supply VCC through the first resistor R1, the base of the first triode Q1 is connected with the collector of the second triode Q2 through the second resistor R2, the base of the second triode Q2 is connected with the collector of the first triode Q1 through the third resistor R3, the emitter of the second triode Q2 is grounded, and the collector of the second triode Q2 is also connected with the CPU power supply VCC through the fourth resistor R4; the collector of the first transistor Q1 is the output terminal of the bistable flip-flop circuit 10; the base of the second transistor Q2 is the input terminal of the bistable circuit 10.

Further, the standby trigger circuit 30 includes a capacitor C, a seventh resistor R7, an eighth resistor R8, a ninth resistor R9, and a fourth transistor Q4; a first end of the capacitor C is connected to the input end of the bistable flip-flop circuit 10, and a second end of the capacitor C is connected to the emitter of the fourth transistor Q4 through the seventh resistor R7; one end of the eighth resistor R8 is connected with the common end of the capacitor C and the seventh resistor R7, and the other end of the eighth resistor R8 is grounded; the base of the fourth triode Q4 is connected to one end of the ninth resistor R9, the other end of the ninth resistor R9 is the detection input terminal OFF _ CTR of the standby trigger circuit 30, and the collector of the fourth triode Q4 is connected to the power control terminal POWEROFF of the CPU 40.
It should be noted that, in this embodiment, when the television is turned on by ac, the power control terminal POWEROFF of the CPU40 defaults to a high level, the detection input terminal OFF _ CTR defaults to a low level, at this time, the first transistor Q1 is turned on in saturation, the second transistor Q2 is turned OFF, the collector of the first transistor Q1 outputs a high level, the collector of the third transistor Q3 outputs a low level, and the MOS transistor Q5 is turned on to control the CPU power supply VCC to output electric energy to the CPU 40. After the television is turned on by alternating current, if the detection input terminal OFF _ CTR of the standby trigger circuit 30 detects an input high level, the fourth triode Q4 is turned OFF, and since no voltage change is generated at the two ends of the capacitor C, the bistable trigger circuit 10 does not receive a trigger signal, the MOS transistor is kept on, the CPU power supply VCC continuously outputs electric energy to the CPU40, and at this time, the television can still realize normal remote control turning on or key turning on. If the detection input end OFF _ CTR of the standby trigger circuit 30 detects an input low level, the fourth triode Q4 is turned on, so that the collector of the fourth triode Q4 detects a low level standby signal of the CPU40, the emitter side of the fourth triode Q4 is also a low level, a voltage drop change occurs at two ends of the capacitor C, the second triode Q2 in the bistable trigger circuit 10 is turned OFF, the first triode Q1 is turned on, the bistable trigger circuit 10 triggers and outputs a first level signal, at this time, the collector of the third triode Q3 outputs a high level, the MOS transistor Q5 is turned OFF, so as to control the CPU power supply VCC to stop outputting electric energy to the CPU40, thereby realizing that the CPU power supply VCC is cut OFF under the standby condition of the television, compared with the current standby condition that the CPU power supply VCC continuously supplies power to the CPU40 through the CPU power supply VCC, saving energy, and being green and environment-friendly.
Further, when the television is in standby and the CPU power supply VCC stops outputting, the base of the second triode Q2 is at low level, when the key trigger circuit 50 triggers and outputs a high-level power-on signal of the television, the base voltage of the second triode Q2 is increased to turn on the second triode Q2, the first triode Q1 is turned off, the first level signal output by the bistable trigger circuit 10 is turned over to output high level by the low level output, the collector of the first triode Q1 outputs high level, the collector of the third triode Q3 outputs low level, and the MOS transistor Q5 is turned on to control the CPU power supply VCC output, thereby realizing key power-on.
It should be noted that the capacitor C in the above embodiment functions to turn off the CPU power supply VCC and reset the flip-flop circuit 10 according to the output of the power control terminal POWEROFF of the CPU 40. In an electronic circuit, the bistable flip-flop 10 is characterized in that the circuit is always in an original stable state without the action of an external trigger signal. The flip-flop 10 flips from one stable state to another stable state upon application of an applied input trigger signal. In this embodiment, the bistable trigger circuit 10 is introduced to make the standby trigger circuit of the television standby power supply operate stably, not easily affected by external factors and self factors, and control is accurate.
In addition, in order to ensure that the bistable flip-flop circuit 10 is not triggered when the power detection terminal OFF _ CTR detects a high level, and the fourth transistor Q4 is turned on when a low level is detected, so as to trigger the bistable flip-flop circuit 10 to output the effect of the first level inversion, the value of the capacitor C needs to be set relatively small, and the seventh resistor R7 and the eighth resistor R8 need to be divided appropriately.
