一种电视机待机控制节能电路

摘要

文章中设计给出了一种减少LCD TV待机状态下功耗的节能电路解决方案。主要是用一个工作于低频率的低功耗芯片8BIT IC，来取代Scaler IC待机工作时对IR/KEY的响应功能，并且能在8BIT IC接收到IR/KEY的开机信号后开启Scaler IC及整个系统，使整个TV在待机状态减少待机元件的数量，减少待机元件的功耗，从而达到节约能源的目的。%This design provides a solution to reduce the energy saving circuit of power LCD TV standby mode. Is mainly low power 8BIT chip IC with a work in low frequency, the response function of IR/KEY to replace the Scaler IC standby when working, and can be received at 8BIT IC to the IR/KEY boot signal after open Scaler IC and the whole system, so that the whole TV reduce the number of standby components in the standby state, reduce power consumption in standby components, so as to achieve the purpose of saving energy.
