Abstract

The utility model provides a device for lowering standby power consumption. The device for lowering standby power consumption comprises a light-emitting diode (LED) screen, a drive chip and a control circuit. An output end of the drive chip is connected with the LED screen, and an input end of the drive chip is connected with an output end of the control circuit. The device for lowering standby power consumption has the advantages that the drive chip is controlled through the control circuit, the standby power consumption of the LED screen is lowered, and electric energy is saved.

Description

Reduce the device of stand-by power consumption

Technical field

The utility model relates to electronic installation, relates in particular to the device that reduces stand-by power consumption.

Background technology

Present LED screen has been widely used in industry-by-industry; The LED screen of for example setting up in the roadside is used for playing advertisements etc.; The LED screen carries out holding state when not working; Though the power consumption of LED screen after getting into holding state is smaller now, does not also reach desirable situation, the power consumption in the time of also need reducing the standby of LED screen once more.

The utility model content

In order to solve the problems of the prior art, the utility model provides a kind of device that reduces stand-by power consumption.

The utility model provides a kind of device that reduces stand-by power consumption, comprises LED screen, chip for driving, control circuit, and said chip for driving output terminal links to each other with said LED screen, and said chip for driving input end links to each other with said control circuit output terminal.

As the further improvement of the utility model, link to each other through data line and control signal wire between said control circuit and the said chip for driving.

As the further improvement of the utility model, this device also comprises power supply, and said power supply links to each other with said chip for driving, is said chip for driving power supply through said power supply.

The beneficial effect of the utility model is: through control circuit controlling and driving chip, reduced the stand-by power consumption of LED screen, practiced thrift electric energy.

Description of drawings

Fig. 1 is the theory diagram of the utility model.

Embodiment

As shown in Figure 1; The utility model discloses a kind of device that reduces stand-by power consumption; Comprise LED screen 2, chip for driving 1, control circuit 3, said chip for driving 1 output terminal links to each other with said LED screen 2, and said chip for driving 1 input end links to each other with said control circuit 3 output terminals.

Link to each other through data line and control signal wire between said control circuit 3 and the said chip for driving 1.

This device also comprises power supply 5, and said power supply 5 links to each other with said chip for driving 1, is said chip for driving 1 power supply through said power supply 5.

Come controlling and driving chip 1 through control circuit 3; When LED screen 2 carries out holding state; Control circuit 3 controlling and driving chips 1 parting system input signal is connected with the signal of chip for driving 1; Make chip for driving 1 no any signal leakage to LED screen 2, thereby make LED screen 2 thoroughly get into dormant state; When 2 work of needs LED screen, be communicated with chip for driving 1 through control circuit 3 control system input signals again, thereby make LED screen 2 get into duty.Through the connection status of control circuit 3 control system input signals and chip for driving 1, reduced the stand-by power consumption of LED screen 2, practiced thrift electric energy.

Be connected with the system control signal line at control circuit 3 input ends, be used for the receiving system control signal.

Above content is the further explain that combines concrete preferred implementation that the utility model is done, and can not assert that the practical implementation of the utility model is confined to these explanations.For the those of ordinary skill of technical field under the utility model, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be regarded as belonging to the protection domain of the utility model.

Claims
