Embodiment Construction

[0030] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0031] The invention provides a TV start-up control circuit. refer to figure 1 , figure 1 It is a structural schematic diagram of the start-up control circuit of the TV set of the present invention.

[0032] In this embodiment, the power-on control circuit of the TV includes: an NFC (Near Field Communication, near field communication) circuit and a relay 200;

[0033] The NFC circuit includes an inductor 101, a capacitor 102 and a processor 103; the inductor 101 is connected in parallel with the capacitor 102, and is used to charge the capacitor 102 when a radio frequency magnetic field is sensed. The capacitor 102 is connected to the processor 103 and the relay 200 respectively.

[0034] The processor 103 includes a storage unit, and the storage unit is used to store the NFC state value corresponding to the NFC s...

Abstract

Disclosed is a start-up control circuit for a television. The start-up control circuit comprises a near field communication (NFC) circuit and a relay, wherein the NFC circuit comprises an inductor, a capacitor and a processor; the processor comprises a storage unit; the inductor is connected to the capacitor in parallel for charging the capacitor; the capacitor is respectively connected to the processor and the relay for making the relay conduct when the capacitor is charged to a pre-set voltage; a movable contact of the relay is connected to a power switch of the television in parallel; and when the relay is conducting, the movable contact is closed, so that a power circuit of the television is conducting. Also disclosed is a start-up control method for a television. When the inductor induces a radio-frequency magnetic field, the capacitor controls the movable contact of the relay to close to conduct a start-up power supply of the television, so that the television is turned on without pressing the power switch of the television, and thus start-up of the television is more convenient.

Description

technical field [0001] The invention relates to the technical field of televisions, in particular to a television start-up control circuit and method. Background technique [0002] At present, in order to save the power consumption of the TV, the user will manually turn off the power switch of the TV when not watching the TV. After the power is disconnected, when the user turns on the TV again, the TV needs to be powered on again by pressing the power switch of the TV. The panel button of the TV can wake up the standby mode, which makes it inconvenient to start the TV. Contents of the invention [0003] The invention provides a TV start-up control circuit and method, aiming to solve the technical problem that the current TV set is inconvenient to start up through a power switch. [0004] In order to achieve the above object, the present invention provides a start-up control circuit of a TV set, the start-up control circuit of the TV set includes: a near field communicati...
