In addition to the above problems, CCFL from the spectral characteristics of the largest defect LED Bulb flaws. We have said above, the white light source is emitted through the light Finally RGB color filter film can be achieved after imaging, so the backlight emitted white light in R / G / B three primary colors of light wavelength
(i.e. the purity of RGB) TV will directly affect the final color effect. From this perspective, CCFL white light emitted is not one kind of ideal light source spectral characteristics. So most of the LCD TVs currently on the market, only to meet the standard NTSC color gamut standard 60% -78%, greatly reduced the effect of natural colors.
Improved CCFL lighting effects are still limited
SONY in 2007 on a large-scale high-end LCD using CCFL backlight improved
Of course, so important in the face of an LCD TV but dragged down overall performance hind parts, each manufacturer is impossible to sit idly by. For the improvement of traditional CCFL technology continues to emerge, such as: Sharp's four-wavelength backlight system, is through the CCFL tubes phosphor performance improvements, making the red spectral composition of the light source performance enhancements,
which to some extent, improve the color reproduction effect; SONY, Samsung and TCL's part of the product is also equipped with WCG-CCFL-type wide color gamut CCFL light source, making the color gamut to achieve about 85% of the NTSC standard; TOSHIBA intelligent backlight adjustment technique is to change the CCFL lit disadvantage, according to the brightness of the screen backlight smart regulation, thereby enhancing the contrast of the TV.
