Backlight is the Weak Electronic Link in the Performance of a LCD Monitor
Since a backlight lights up the screen, losing it will cause the screen to dim, and hence, it is a weak electronic link in the overall usability of a LCD monitor.
Here are some facts about LCD backlights: • A backlight is a thin fluorescent tube that lights up the LCD screen • Most backlights are either EL (electroluminescent) or CCFL (cold cathode fluorescent lamp) • A new backlight tube has a life span from 5,000-15,000 hours of usage before it loses 50% of its brightness.
