High energy-saving circuit for a display apparatus

摘要

A high energy-saving circuit for a display apparatus controls turn on and/or off of an AC voltage supply terminal by the simple circuitry of a sensor, an operation controller and an output unit for effecting automatic reset on an analog basis without supplying power to a microprocessor by providing an auxiliary power supply circuit in an input signal off-mode, whereby power is economized and the total AC power pauses to save the power consumed heretofore in peripheral equipment such as printers.
