After turning off the TV, unplug the connector and save power. This "great" discovery has long been deeply embedded in the minds of most people. But is it still true that technology has developed to this day?
DC shutdown and AC shutdown
First of all, we must be sure that the effect is the same when we unplug the plug and turn off the switch on the TV. There is a power switch on the TV itself and it is not powered on when the TV is plugged in.
Ordinary users often use a word - "standby." In fact, the term is very rigorous. The formal name is "DC shutdown."
The opening and closing of the TV is controlled by the internal AC relay. The switch of this relay is the physical switch button on the TV. The DC equipment such as kinescope is controlled by the signal of the remote controller.
In other words, if the remote control is turned off, only the screen of the TV is turned off, and the internal relays and other devices are still on.
People therefore think that AC shutdown is more power-efficient than DC shutdown. But is this really the case?
power consumption
Before 2012, the relay was powered at 15W. For TVs shipped after 2012, new standards will be implemented and the relay power will not exceed 0.5W.
In addition, the power consumption of the relay at startup is several times that of normal operation.
Therefore, for a frequently used TV set, frequent AC switches are more power consuming than DC shutdown.
Therefore, we only need to handle the TV plug when not using the TV for a long time. For TVs that are activated multiple times per day, you only need to press the Shutdown button on the remote control.
