DISPLAY APPARATUS AND LED CONTROL METHOD THEREOF

摘要

A display device and an LED control method thereof are provided to fade out an LED when the display device is turned on, and fade in the LED when the display device is turned off. An LED unit(50) indicates a power status at a front side of a main unit casing. A power switch(40) receives power-on/off input from a user. A controller(60) fades out the LED by applying a PWM(Pulse Width Modulation) control signal to the LED unit when the power switch is turned on, and fades in the LED by applying the PWM control signal to the LED unit when the power switch is turned off. The LED unit includes an LED outputting light and an RC(Resistor-Capacitor) filter circuit providing operational current to the LED according to the PWM control signal.
