Therefore, a backlight is provided on the back of the liquid crystal display to irradiate light. As a result, the image can be seen even in a dark place. Typical requirements for backlights include high brightness, high efficiency, uniformity of brightness, long life, thinness, low weight and low cost. For notebooks, high efficiency long life lamps are required to reduce power consumption. High brightness is required.

At this time, the fluorescent lamps used in the liquid crystal display are classified according to the position of the electrode. The cold cathode fluorescent lamp (CCFL) and the hot cathode fluorescent lamp (HCFL) in which the electrodes are located inside the fluorescent lamp And an external electrode fluorescent lamp (EEFL) in which the electrode is external. Common fluorescent lamps are hot cathode fluorescent lamps, and the backlights used in notebooks and monitors use cold cathode fluorescent lamps with low heat and long life.

Recently, when high brightness is required, such as LCD-TV or billboards, many fluorescent lamps should be used. An external electrode fluorescent lamp (EEFL) is advantageous in terms of lifespan and manufacturing cost.
