Internal Parts in LCD Monitor Atau Isi Dalem Monitor LCD

 

Currently, the most commonly used light emitting device is a fluorescent tube called a cold cathode tube for CCFL. The CCFL is called a cold cathode tube because even though the principle of illumination is the same as that of the hot cathode tubes used by indoor lamps, this lamp does not require preheating of the filament.

Also, the electrodes at the end of the bulb stay at a low temperature while emitting light. CCFL also enjoy a long life (approx 50,000 hours) without serious degradation. A special power supply, inverter, which generates approximately 600 to 1000 AC is required to drive a CCFL. This inverter is a small power supply used to make this CCFL illuminate, and is one of the important functional parts of a complete LCD display.

Display Flicker and Reddish

Normally a reddish display and display flicker in LCD Monitor were caused by one of the defective backlight (either top or bottom backlight). For those LCD Monitors that do not have the feedback circuit in the inverter board, even though the backlight have problem the LCD Monitor continue to work and never shutdown. This is totally different in LCD Monitors that have the feedback circuit in the inverter board because even a slight flicker in the display caused by a defective backlight, the LCD Monitor would immediately shutdown
