The difference between LED TV and LCD TV is mainly in the type of backlight, color performance, energy saving and environmental protection, and product appearance. Here's a concrete explanation of these differences:
1.Backlight Type:
LCD TVs: Cold cathode fluorescent lamps (CCFLs) are often used as backlights to convert electrical energy into light energy through a fluorescent substance.
LED TV: It is actually an LCD TV that uses LED as a backlight. LEDs can directly convert electrical energy into light energy without passing through a fluorescent substance.
2.Color Expression:
LCD TV: The color performance is already quite good, but it is limited by the color gamut range of the CCFL backlight.
LED TV: Because the LED backlight has a wider color gamut range, the color performance is richer and more vivid, and the picture is more realistic and natural.
3.Energy saving and environmental protection:
LCD TV: Compared with CRT (cathode ray tube) TV, energy consumption has been greatly reduced, but there is still a certain gap compared to LED TV.
LED TV: LED backlight has higher luminous efficiency, so the energy consumption of LED TV is lower, which is more in line with the requirements of energy conservation and environmental protection.
4.Product Appearance:
LCD TV: The body may be relatively thick, limited by the backlight technology and structural design.
LED TV: The body can be thinner and lighter, because the LED backlight allows for a more compact design, and the LED beads can be evenly distributed behind the screen, reducing the need for thickness.
It should be noted that many of the so-called "LED TVs" on the market are actually LCD TVs with LED backlights, so they still belong to the category of LCD TVs in technology. However, as an improved type of LCD TV, the backlight technology of LED TV makes the TV have advantages over traditional LCD TVs in terms of color performance, energy saving, environmental protection and product appearance.
