There is no difference in essence. They all use the liquid crystal as the display panel. The liquid crystal itself does not emit light. It needs to be illuminated by an external light source, just like a shadow play. The current LCD TVs all use cold cathode light, which consumes a lot of power and will turn yellow after a long time, leading to LCD TV picture distortion. LED is a new type of energy-saving light source, it has small volume, wide color gamut, low energy consumption, is the main light source in the future!

LED is a new type of energy-saving light source. It has small volume, wide color gamut and low energy consumption. It is the main light source in the future!. The backlight of LED LCD TV is the main part of LED. General LCD TV is the same as CCFL lamp, which is equivalent to fluorescent lamp. The advantages of LED backlight are high luminous efficiency, saving energy, richer electric spectrum than CCFL, thinner and more uniform light. Moreover, LED is now driven independently to achieve dynamic backlight, which can improve the contrast and long service life. CCFL's high-voltage inverter is not needed. But the price of LED backlight is too expensive. Generally speaking, it is not recommended to buy LED backlight TV. It is too expensive. If you have money, you can consider it.
