APPARATUS FOR SAVING POWER OF LCD MONITOR WITH DISTANCE SENSOR AND METHOD FOR SAVING POWER OF LCD MONITOR USING THE SAME

摘要

There is PURPOSE:LCD monitor battery saving arrangements range sensor and LCD monitor power saving method to use the reduction energy waste, and by processing power saving movement, these movements close backlight and utilize range sensor. ;A kind of CONSTITUTION: the distance between infrared distance sensor (21) output value LCD monitor and user. Variable resistance (22) movement changes normal voltage apart from establishment of the port. Output valve and fixed standard voltage are determined that there are users by comparator (24). The logic product of circuit (25) carries out logic multiply backlight control and outputs and inputs backlight control signal. ;The 2012 of copyright KIPO submissions
