AI Technical Summary

Technical Problem

When the existing display enables the Wake-on-LAN function, the main processor needs to maintain the operation of some circuits, which makes it difficult for the standby power consumption of the whole machine to be reduced to below 0.5W, thus failing to meet the low power standby requirements, and the Wake-on-LAN function has low reliability.

Method used

The system employs a combination of a main control module, a co-control module, a network switching module, a signal switching switch, and a power management module. The co-control module processes standby signals, shuts down the network port and power supply of the main control module, utilizes the lower bandwidth co-control module and the network switching module for network wake-up, and ensures network address consistency through an address verification mechanism, thereby achieving dynamic power consumption management.

Benefits of technology

The reliability of the display's Wake-on-LAN function has been improved, and standby power consumption has been reduced, meeting the technical requirements for low-power standby.

Abstract

This invention discloses a low-power standby method and system for a display screen, belonging to the field of electronic technology. The method includes: responding to a standby signal, a co-control network address, and a main control network address acquired by the main control module; comparing the co-control network address and the main control network address; if the co-control network address matches the main control network address, receiving the standby signal to obtain a standby control signal; based on the standby control signal, instructing a signal switching switch to open the network ports of the co-control module and the network switching module, and close the network ports of the main control module and the network switching module; and instructing a power management module to shut down the power supply to the main control module, thereby completing the low-power standby process of the display screen. The method disclosed in this invention can improve the reliability of the display screen's network wake-up function and reduce standby power consumption by shutting down the high-power main control module and transferring control authority to the co-control module.
