Cold cathode fluorescent lamps have the characteristics of small size, high brightness and long life, but need to be preheated before work. Such light sources have been widely used in liquid crystal displays, backlights of liquid crystal televisions. Backlight for LCD monitors - Cold Cathode Fluorescent Lamps, CCFL
The main product categories of backlight modules are: light-emitting diodes (LED), tungsten halogen lamps, electroluminescence (ELD), cold cathode fluorescent lamps (CCFL), cathode emission lamps (CLL), and metal halide lamps. Among them, the process is mature and the performance is stable. The backlight commonly used in color liquid crystal displays (TFT-LCDs) is a cold cathode fluorescent lamp (CCFL); on a small-area LCD, an LED backlight is commonly used, especially for uniform illumination. High-efficiency side backlight is the main application range of LED backlights: LCD display panels such as mobile phones, PDAs, game consoles, household appliances, instruments, instruments, digital products, automotive application parts and other products.
CCFL has a small market prospect with the maturity of liquid crystal display technology, and its annual growth rate remains above 60%! At present, Japan is the largest manufacturer of CCFL devices with a market share of about 60%, followed by Taiwan, with a market share of about 18%. .
