 CCFL light defect is the main reason

Although CCFL LCD TVs currently in the mainstream has been widely used, but does not mean that this is a best solution. For a long time, subject to the principle of CCFL technology and production processes, CCFL generally tubular light sources, to achieve uniform backlighting, the lamp must be used to simulate a real number of a surface light source.

 The resulting high-power, high-calorie very obvious, and can not achieve the perfect flat light. In addition, CCFL light source life of only 50,000 hours or so, and with the growth in the use of time, light source emits light will dim and yellow. As the LCD TV backlight remains constant as long as the boot after consistent state, so that, after a few years in the use of the LCD TV will happen obvious color cast, light attenuation issue.

Even the black state, but also can be found in significant leakage, which is one of the drawbacks CCFL. In addition, CCFL brightness are generally constant, even liquid crystal molecules in the fully closed state, there will be some of the light coming from the transmission, so the current LCD TV difficult to demonstrate a true black, which also led to the poor contrast of the LCD TV defects.
