Embodiment Construction
[0017] There are many combinations when using various phosphors to make CCFL:
[0018] One type applies phosphors of various spectral lines to the inside of the same CCFL lamp tube. The embodiment of the present invention is to coat phosphors of five spectral lines of red, green, blue, blue, and yellow in a CCFL lamp tube. The main peak wavelength of the spectral line of the cyan phosphor is between 470-500nm, and the main peak wavelength of the spectral line of the yellow phosphor is between 550-590nm. The advantage of this method is that it does not change any structure of the existing backlight system.
[0019] The second type divides phosphors of various spectral lines into several groups and coats them in different CCFL lamp tubes to make mixed color lamp tubes. For example, the five spectral lines of red, green, blue, blue and yellow can be divided into two groups for coating. One group is red, green and blue three-color fluorescent powder coated inside a CCFL lamp tube...
