LED backlight: power saving (30% ≤ 50% compared with ccfl), high price, high brilliance and saturation.
CCFL backlight: compared with led backlight power consumption (or much more power saving than crt), cheap.
Picture difference: led backlight color is bright, saturation is high (ccfl and led natural light source is not the same).
How to make the difference: the led backlight will emphasize that what led tv, does not emphasize is ccfl lcd tv.
There are real light-emitting diodes tv (no-back light, active light-emitting), sony and samghton, but the panel is currently under 11 inches and the price is very expensive, as sony 11-inch amoled tv is asking about rmb18000, which is a high-end market, so there is little on the market.
Let's look at the actual picture contrast map of the difference between the lcd and the led, the following two notebook displays: the ccfl backlight type lcd on the left, the led back light type lcd on the right, and the pair of three colors red, green and blue, for example, the figure below: as can be seen from the figure, The color difference between the lcd screen and the led screen is not great. It is not necessary if you only pay for the name of a light-emitting diode (led) that is not commensurate with it.
