Problems solved by technology

[0003] However, even if the existing display device 900 enters the standby mode, the AC power supply will continue to provide voltage to the power circuit board 910, so that the internal system of the display device 900 will continue to consume power and consume energy.
To solve this power consumption problem, consumers must plug and unplug the power plug on the wall, but this method will cause trouble and inconvenience for consumers

Embodiment Construction

[0027] The aforementioned and other technical contents, features and effects of the present invention will be clearly presented in the following detailed description of three embodiments with reference to the accompanying drawings.

[0028] refer to figure 2 , is the first embodiment of the power control system 100 of the present invention. The power control system 100 includes a display device 1 and a remote control device 2 .

[0029] In this embodiment, the display device 1 is a flat-screen TV and includes a power circuit board (Power Board, 10) for processing high-power AC / DC conversion and a main circuit board (Main Board, 20) for controlling the operation of the display device 1. . The power circuit board 10 is provided with a relay (Relay, 11) for receiving an alternating current (AC) power supply. The voltage range of the AC power supply in this embodiment is 100-204 volts for matching various types of flat-screen TVs, and the relay 11 is a A photorelay is an automa...

Abstract

Provided is a power control system including a display device and a remote control device. The display device includes a relay for receiving an AC power supply, a control circuit that is electrically connected to the relay, and a receptive circuit that is electrically connected to the control circuit. The remote control device includes a transmission circuit that is capable of establishing a connection with the receptive circuit of the electronic device. The remote control device is operable to transmit via the transmission circuit a triggering signal to the receptive circuit. Upon receipt of the triggering signal via the receptive circuit, the control circuit generates the driving voltage based on the triggering signal. When the transmission circuit is triggered to transmit an electrical signal to the receptive circuit, the control circuit generates a driving voltage sufficient for driving the relay based on the electrical signal to start the relay, so that the AC power supply can supply electricity to the display device for driving operation thereof. Therefore, the off of the relay completely isolates the AC power supply from the display device, so that the display device can be less than the international standards of 1 Watt / hr without consuming any voltage to achieve overall electricity consumption.

Description

technical field [0001] The invention relates to a power control system, in particular to a power control system capable of achieving complete power-off control. Background technique [0002] The earth's resources are becoming increasingly scarce, and the home appliances that are actively energy-saving and electricity-saving in various countries have strict scales. In the case of flat-screen TV products, the international norms must be less than 1Watt / hr in standby mode, and figure 1 For the display device 900, the display device 900 includes a power circuit board (Power Board, 910) that handles high-power AC / DC conversion and a main circuit board (Main Board, 920) that controls the operation of the display device 900. When consumers When you want to turn off the display device 900 or do not use the display device 900 for a long time, you will press the power button of the remote controller (not shown), so that the display device 900 enters the standby (Standby) mode, wherei...
