Embodiment Construction

[0016] The present invention aims to propose a control method and circuit for passive standby power supply of a Wi-Fi module of a flat-panel TV. When the power supply of the Wi-Fi module is cut off in the normal standby state, the power supply of the Wi-Fi module meets the mandatory detection and certification of relevant national standards, and after the user connects to the mobile phone client Keep the power supply of Wi-Fi module in standby to meet the needs of users.

[0017] Such as figure 1 As shown, the control circuit of the passive standby power supply of the flat panel TV Wi-Fi module among the present invention comprises: Wi-Fi module power supply, control port, switch circuit, Wi-Fi module; Described Wi-Fi module power supply connects switch circuit Input end; the control port is connected to the control end of the switch circuit; the output end of the switch circuit is connected to the Wi-Fi module; the control port provides two output states of high level and low...

Abstract

The invention relates to the technology of flat television control and discloses a flat television Wi-Fi (Wireless Fidelity) module passive standby power supply control method and circuit. When a flat television is under a normal state and standby, power supply of a Wi-Fi module is cut off to satisfy a constraint detection authentication of a national relevant standard. When a user connects the flat television with a mobile phone client and the flat television is standby, power supply of the Wi-Fi module is kept to satisfy a user utilization requirement. According to the flat television Wi-Fi module passive standby power supply control method and circuit, after the flat television is turned on, a television system rises a control port electrical level, the state of the control port electrical level is a high electrical level, a switching circuit switches on the power supply of the Wi-Fi module, and the system sets a standby switch identification state of the Wi-Fi module according to specific utilization conditions of a user; when the flat television is standby, the system detects the standby switch identification state of the Wi-Fi module and switches on or switches off the power supply of the Wi-Fi module according to the switch identification state. The flat television Wi-Fi module passive standby power supply control method and circuit is applicable to the flat television.

Description

technical field [0001] The invention relates to a control technology for a flat-panel TV, in particular to a control method and a circuit for passive standby power supply of a Wi-Fi module of a flat-panel TV. Background technique [0002] On June 9, 2013, the country issued the mandatory standard GB24850-2013 "Flat Panel TV Energy Efficiency Limits and Energy Efficiency Grades", which was officially implemented on October 1, 2013. The revised standard requires that the passive standby power of flat-panel TVs must be less than or equal to 0.50W. [0003] With the development of intelligent home appliances, Wi-Fi modules have basically become the standard configuration of flat-panel TVs. Functions such as mobile phone client interaction and wireless network wake-up are gradually applied to the field of flat-panel TVs to provide users with better services and experiences. Some functions require that the built-in Wi-Fi module of the flat-panel TV is in the working state when i...
