LCD Monitor CCFL What is

CCFL backlight screen Advantages and disadvantages CCFL full name cold cathode fluorescent lamp (cold cathode fluorescent lamp), with high power, high brightness, low energy consumption and other advantages, widely used in display, lighting and other fields, filled with inert gas (including part of the mercury vapor), the inner wall has phosphor layer, The shape looks like a fluorescent tube, a bit like a neon sign in the city. Because the CCFL tube has a small tube, simple structure, lamp surface temperature rise small, lamp surface brightness high, easy to process into various shapes (straight tube, L-shaped, U-shaped, ring, etc.), long service life, good color, luminous uniformity and so on, so is the current TFT-LCD screen ideal light source, At the same time widely used in advertising light boxes, scanners and backlight and other uses.

Before the CCFL, more is the use of EEFL backlight technology backlight, CCFL backlight technology and the following wled are very mature technology, and RGB LED is still not too mature, exactly, to design a higher point, so many three-flow manufacturers are difficult to design a good quality RGB LED backlight display.

CCFL Backlight Screen Advantages: Low cost, simple manufacturing process, mature technology.

CCFL backlight Screen Disadvantage: Short life (fast aging), low luminous efficiency (power consumption), low brightness uniformity, low color purity, poor color performance, environmental protection, large volume, high driving voltage, not withstand impact.
