As the mainstream display, LED small-pitch display and LCD splicing screen. Although many people use them, and they are similar, but the essence is very different, one uses LED diodes, and the other is LED backlight source , they also have their own advantages in size, power, brightness, etc. Let’s take a look at the difference between LED small spacing and LCD splicing screen?
LED small pitch display: LED large screen is a display that uses LEDs (light-emitting diodes) as pixel light-emitting elements. The light-emitting diodes forming an array directly emit red, green, and blue light, forming light-emitting segments or light-emitting points, and forming digital tubes, Symbol tube, meter tube, matrix tube and level display tube, etc., and then form a color picture.
LCD splicing screen: The material of the LCD backlight itself does not emit light, and the light source on the back of the LCD panel is required to provide light support. Before the emergence of LED backlights, CCFL cold light tubes were the main light sources. The light-emitting principle was similar to fluorescent tubes, but the disadvantages were uneven brightness, high power consumption, and mercury elements. The LCD backlight was born to solve the problem of CCFL cold light tubes. This is also the main reason why LCD-backlit liquid crystal displays are popular in the market.
LED small spacing can display text, pictures, videos, numbers and other information, and can also be used indoors and outdoors. It integrates microelectronics technology, computer technology, and information processing. It has a wide dynamic range, high brightness, long life and bright colors. And the characteristics of stable performance, become the darling of outdoor advertising.
At the same time, it can also automatically adjust the brightness of the screen itself according to the brightness of the surrounding environment, which can adapt to all kinds of bad weather. It has unique advantages in waterproof, moisture-proof, lightning protection, earthquake resistance, etc.
LED TV screen: LED TV screen is usually what we call LCD LCD TV display. Compared with LED display, the difference is that the backlight source is different. LED TV and LED display also use light-emitting diodes, the difference is that one is a display as a pixel light-emitting element, and the other is a backlight. The thickness, power and picture quality of LED TV are better than traditional LCD TV CCFL backlight, more energy saving and environmental protection.
The reason why LCD splicing screen is also called LCD LCD TV is that LED TV uses LED as backlight source, and LCD LCD screen also uses backlight source. In addition, LED TVs use LED light sources to replace traditional fluorescent tubes, making them better quality, longer service life, more energy-saving and environmentally friendly, and thinner.
Institutional research has found that the reaction speed of a single element of the LED display is 1000 times that of the LCD liquid crystal screen, and it can be looked after under strong light, and it can adapt to the low temperature of minus 40 degrees.
The above is the difference between LED small-pitch display and LCD splicing screen introduced by LED display manufacturers. The two also use light-emitting diodes. The difference is that one is a display screen as a pixel light-emitting element, and the other is used as a backlight.
Knowing the difference between them, how should we choose if we want to install it in the conference room?
In essence, the splicing screen adopts LCD liquid crystal technology and LED technology, so the overall display effect and application scenarios are different, and other aspects have their own advantages and disadvantages, and the choices of users are also different.
For example, users who pursue clarity prefer to use splicing screens , and users who don’t like the look and feel of seams may prefer to use LED fine-pitch displays. Let’s take a look at the advantages of both.
First, the advantages of LCD splicing screen
- High definition
The advantage of the splicing screen is that the resolution is high, the single screen can reach 1920*1080, and it can realize 4K display and 8K display function at the same time.
- Brightness is suitable for long time viewing
Generally, the brightness of the splicing screen is moderate, which is slightly brighter than the TV and will not hurt the eyes when watching for a long time.
- High contrast
The contrast ratio of the splicing screen can reach 5000:1 and the color is rich.
- The panel is stable and suitable for long-term startup
The panel of the splicing screen is industrial grade, which can meet the requirement of 24-hour power supply.
- Diverse connection functions
The splicing screen also has a splicing function. After splicing multiple screens, a screen of any size can be formed, and a large image can be displayed across the screen, and multiple small images can be displayed at the same time. If it is used for monitoring display, it can also realize display such as division.
Second, the advantages of LED small-pitch display
- No seams
Seamless is the biggest advantage of LED small-pitch display. In any case, there is no visual obstacle between the connected screens. The integrity is very good, and the LCD splicing screen can only be set to the corresponding size before leaving the factory. When the two screens are put together, you will see more obvious slits.
Therefore, in terms of integrity, the display effect of LED screen is better than that of LCD splicing screen.
- Brightness can be adjusted
The brightness of the LED screen can be adjusted freely, and even unattended automatic brightness adjustment can be achieved through light control or voice control sensors, which is more flexible than the LCD splicing screen that can only manually adjust part of the brightness.
- Suitable for large size viewing
The LED display can be assembled infinitely, and the area can reach thousands of squares. The LCD can only be displayed in a fixed size. Once the area is too large, it will face big problems whether it is installation or transportation.
