Mercury cold cathode fluorescent lamp gradually reach the practical stage oled module

Due to the current cold cathode fluorescent tubes, the use of mercury to be discharged, so there has been shadow impact on the environment, and coupled with the EU RoHS norms, which is about to face. EU regulations from July 1, 2006, Controlling contain lead, cadmium, mercury, and hexavalent chromium and brominated flame retardants and other elements or application products imports.
Currently industry is still unable to effectively locate the cold cathode fluorescent lamp mercury alternatives, although the EU will not fully control, but has cold cathode fluorescent lamps containing mercury has made no more than 5mg limit. On industrial technology, has been able to overcome contains mercury does not exceed the upper limit of 5mg, reaching about 3mg or less, but in the long run, the threshold of mercury is still to be overcome. Character LCD Modules
Meanwhile, the use of mercury discharge factor, if the ambient temperature is too low, can also cause the phenomenon is not easy to start, this especially in the temperate and boreal markets becomes more apparent. In addition to the impact caused by difficult start, the temperature of the environment because of the use of mercury vapor pressure will also cause the luminance and luminous efficiency including some impact, so the cold start and other environmental issues is the cold cathode fluorescent tube technically most urgent be solved. Because of such factors backdrop, mercury cold cathode fluorescent tube development, has become all the cold cathode fluorescent lamp industry eager to resolve the issue. Low Temperature Display
