led backlight compared to traditional ccfl backlight, led backlight and ccfl backlight generally  led lighting china the same size compared to commercial grade products can save more than 40% in energy efficiency has greatly improved. in addition, ccfl backlight mercury considerable harm to the environment of a substance, but the led backlight does not contain such harmful substances, more environmentally friendly. ceiling light led backlight technology advantages of the two: slim elegant led backlight is set by the number of grid-shaped semiconductor components, each "grid" has an led semiconductor, so that you can successfully achieve the light source plane. the plane of the light not only has excellent brightness uniformity, do not require sophisticated optical design. as a result, lcd thickness can be done more light, while with higher reliability and stability. led down lights belong to the traditional ccfl tube light, they emit light evenly to spread to every region of the panel requires quite complex auxiliary components. it is difficult to control the thickness of the screen, and with the increase of the panel, you must use multiple light sources, which further exacerbated the design complexity and cost, large-screen lcd tvs are more sensitive to this. for example, more than 50 inches of lcd or tv product, its direct type backlight ccfl may account for the proportion of the cost of more than half the cost of the panel.   the three led backlight technology advantages: ultra-wide color gamut led backlight with a more uniform luminescence characteristics of the color performance far better than the ccfl backlight on. insufficient number of available colors on an lcd display technology play a good role to make up, easy ntsc118% or more wide color gamut, so lcd monitors are truly colorful nature to restore the bright colors.
