The display is a back light source to illuminate, so the length of the display's life depends on whether the backlight is safe or not. Current displays are divided into CCFL and LED backlights. Cold cathode fluorescent (CCF) lamps are the most commonly used backlight sources in LCDs. In industrial display applications, CCF backlights typically last for at least 50,000 hours.
LED is the LED we often say. At present, the official life of LED backlights on the market is 50,000 to 100,000 hours. Compared with CCFL, the service life is obviously improved.
