CCFL find alternative element mercury TFT Display Module

In the absence of mercury cold cathode fluorescent tube technology development, global industry are positive expectations to find a substitute for mercury, but because of the relationship between characteristics and goals, have been unable to locate or high performance and mercury as a substitute for mercury element. Expected to achieve the required gas requires several conditions, including: First, to a very strong UV radiation intensity to achieve high luminance requirements. Second, the ultraviolet wavelength fluorescent wall can not bring too much damage that would otherwise occur lamp wall early deterioration phenomenon, making the life of the cold cathode fluorescent tube rapidly shortened. Third, it requires a longer ultraviolet wavelengths, as long wave ultraviolet light can be improved longer visible light conversion efficiency and improve the overall performance of the cold cathode fluorescent tube. graphic lcd 128x64
Due to the above conditions, has been developed more Xe gas to replace the use of cold cathode fluorescent tube mercury as fluorescent lamps discharge medium. The structure is being taken in the inner wall of the glass tube coated with fluorescent powder and sealed xenon gas. Disposed at one end of the glass tube with the general CCFL same internal electrode, and the spirally wound wire to the lower tube wall, as the other electrode. By applying a voltage between the internal and external electrodes to form a discharge, Xe gas discharge UV fluorescent powder is converted into visible because light. OLED Display
