Mercury CCFL difficult to overcome technological bottlenecks environmental temperature TFT Display Module

In general, the cold cathode fluorescent tube used in inorganic mercury are mercury, and organic mercury compared to that of the human body to a lesser extent, but the current cold cathode fluorescent tubes discarded most of the use of landfill The way to deal with, however, such an approach would make obsolete cold cathode fluorescent inorganic mercury in organic produce, also faced the issue of environmental protection, making the cold cathode fluorescent lamps, mercury-based requirements have continued being emerge. OLED Display Module
Of course, no mercury cold cathode fluorescent tubes in terms of not only refers entirely without mercury, which also includes the use of a small amount of mercury and technologies to meet environmental standards. The so-called implication is that using a small amount of mercury in the cold cathode fluorescent tube by adding a certain small amount of mercury, and mercury in these cold cathode fluorescent lamp life is reached, while also being consumed completed, and let the cold cathode fluorescent abandoned Lamp will not have much impact on the environment.
In addition, use of the environment in terms of the face, the use of mercury discharge cold cathode fluorescent tube and a biggest problem is that mercury discharge to a very high temperature sensitivity at different temperatures, there will be considerable pressure changes (Figure I), this will have on the overall performance of the display panel to bring a certain extent, perhaps in temperate regions the products to achieve color accuracy requirements, but once sold to the arctic or tropical regions the market, often color accuracy will be some differences. graphic lcd display module
Figure a pressure curve can be seen, when the temperature rises or falls several degrees, the mercury vapor pressure will be a considerable degree of change, thereby affecting the overall performance. On the ambient temperature, the boreal regions by the problems more than the tropics, resulting in a low temperature environment because of difficulty in starting, you need a longer time to reach the standard brightness and so on.
For such a phenomenon problems in the boreal areas, mostly applicable to make use of the mercury vapor pressure heater rise, and troubleshoot startup problems, and so subject. There is a very important point, because the lack of mercury wall protection, making the UV will continue to directly impact the wall, making the wall will appear premature aging and thus affect life expectancy.
