What is the difference between LED TV and LCD TV?

There are some differences between LED TVs and LCD TVs in terms of display effects and energy consumption: 1. LED TVs use LEDs as backlight sources, while LCD TVs use cold cathode fluorescent lamps as backlight sources; 2. LED TVs have poor contrast ratio , the black performance and color saturation are relatively better, while the LCD TV is relatively weak in contrast and black performance; 3. The cost of LED TV is higher, while the price of LCD TV is relatively low and more economical; 4. LED TV Usually lower in terms of energy consumption.

LED TVs and LCD TVs are both products of liquid crystal display technology, and they are similar in display principles. However, they differ in backlight, resulting in some differences in display effects and energy consumption.

Liquid Crystal TV (LCD TV):
LCD TV uses cold cathode fluorescent lamps (CCFL) as the backlight source. This backlight produces uniform white light, which is controlled by the LCD panel so that the light passes through the pixels to display different colors and brightness. LCD TVs have good display effects and relatively low prices, but they are relatively weak in contrast and black performance.

LED TV:
LED TV uses LED (Light Emitting Diode) as the backlight source. There are two types of this backlight: direct LED and edge LED. Direct LEDs place hundreds to thousands of LED lights throughout the backlight area, while edge LEDs are located only at the edge of the screen. This makes LED TVs relatively better in contrast, black performance and color saturation, and also has a narrower body design. In addition, LED TVs are generally lower in energy consumption.

Summary:
The main difference is the backlight. LCD TVs use CCFL backlights, while LED TVs use LED backlights. Due to different backlight technologies, LED TVs are relatively better in terms of contrast, black performance and energy consumption. However, when it comes to cost, LCD TVs are generally more affordable. When choosing, you can weigh the pros and cons based on your personal needs and budget. It is worth noting that most of the LCD TVs on the market today refer to LCD TVs with LED backlights. It is also reasonable to call them LED TVs directly.
