Abstract: An intelligent switch system with reduced power consumption includes a wireless gateway, single live line intelligent switches, and one load per single live line intelligent switch. The wireless gateway generates wake-up signal, couples the wake-up signal to the alternating current power source network, and sends a control signal to all the intelligent switches. Each switch includes first wireless communication unit with sleep mode and wake-up mode, first wake-up unit, first controller, and switch unit. Every first wireless communication unit in wake-up mode receives the control signal. Every first wake-up unit receives and the wake-up signal to wake-up the first wireless communication unit if the control signal is tailored for that switch. The first controller analyzes the control signal and outputs a switch signal, the switch unit changes the on or off state of the load accordingly. When the switch unit is turned off, the current flowing is less than 50 uA.

Abstract: A liquid crystal display includes a liquid crystal panel switchable between normal mode for displaying images and standby mode, a control circuit coupled to the liquid crystal panel controlling the liquid crystal panel mode according to video signals transmitted thereto, and a power board providing a power voltage to the control circuit. When the liquid crystal panel is in a standby mode, the control circuit outputs a corresponding feedback signal to interrupt power voltage supply from the power board to the control circuit.
