The difference between LED display and LCD display and which one is better?


Both LED display and LCD display are familiar to users. They are mostly used in the production of TVs, mobile phones, etc., especially TVs. Many users will be entangled in choosing LED displays or LCDs when buying TVs. The display screen is good. In this issue, I will introduce the difference between LED display screen and LCD display screen and which one is better, for the reference of owners.

1. What are LED display and LCD display?

1. LED display

LED LCD screens use LED light sources, which are light-emitting diodes. Such light-emitting diodes are very power-saving, and because they are not light tubes, they can form an array one by one and evenly distribute them behind the LCD screen. Brightness is good, making the backlight more uniform. Such a display can be made thinner and more power-saving, and the life of LED is longer than that of CCFL, and the color is stable and not easy to yellow.

2. LCD screen

Ordinary LCD screens use CCFL light sources, that is, cold-cathode fluorescent lamps (similar to the scanning lamps in the copy), with one on each side of the screen and a backlight on the back of the display, which is composed of fluorescent substances. The light sources on both sides can be evenly distributed on the back of the entire screen, so that the entire screen can be evenly illuminated. However, due to technical limitations, the brightness of such a display is not completely uniform, but it is difficult to find it. At the same time, the lamp also has a certain lifespan, and it will turn yellow after a long time.

Second, the difference between LED display and LCD display

1. Compared with liquid crystal displays, LED displays have more advantages in terms of brightness, power consumption, viewing angle and refresh rate. Using LED technology, it is possible to create displays that are thinner, brighter and clearer than LCDs.

2. The power consumption ratio of LED display and LCD display is about 1:10, and LED is more energy-efficient.

3. The LED display has a higher refresh rate and better performance in video.

4. LEDs provide a wide viewing angle of 160°, which can display various text, numbers, color images and animation information, and can play color video signals such as TV, video, VCD, DVD, etc.

5. The resolution is different. The biggest advantage of the LCD splicing screen is that it can realize high-definition display, that is, 1920*1080, which can display high-definition images and videos, etc., and the LED display screen has a relatively large pixel pitch, so the resolution is higher under the same display area. Much lower, although the resolution can also be superimposed to high-definition, but the required display area is larger, and the viewing effect is obviously not as good as LCD.

6. LCD splicing screens have splicing gaps of different sizes, ranging from 5.5-1.7mm, so there will be physical viewing edges between the screens after splicing, which will affect the viewing effect when the entire screen displays one surface, and LED does not have this kind of worry. No matter how it is spliced, the LED display has no black borders.

7. The LCD display is not waterproof and is mainly used indoors, while the LED display can be used in various occasions, even outdoors.

Conclusion: The above is an introduction to the difference between LED display and LCD display. As for which of the two is better, it depends on the main purpose and the environment in which it is used. The one that is suitable is the best. Users can choose according to their own needs. Just buy it.
