First of all, the display technology is different
The large LCD splicing screen adopts LCD backlight technology, the display technology is the same as our home TV, but the resolution is usually 1920 * 1080. Now LCD splicing screen technology is more advanced, it has reached 4K, even 8K. Our family TV has reached 3840 * 2160.
The LED display adopts LED technology, and uses three-primary-color lamp bead chips to be packaged into pixels for display. Our common traffic lights, billboards, etc. are all LED displays. There is a relatively intuitive feeling, the screen of the LED electronic screen is a lot of small points.
LCD splicing screen and LED
Secondly, the resolution is different
The biggest advantage of the large LCD splicing screen is that it can achieve high-definition display, that is 1920 * 1080, or even higher resolution, can display high-definition images and videos, etc., while the LED display has a larger pixel pitch, so it can distinguish the same Display area. Although the resolution can be superimposed to high-definition, but the required display area is larger, and the viewing effect is obviously not as good as liquid crystal, so the rate is much lower. Therefore, the visual range of the LED electronic screen is long-distance, large-screen, and looks like an effect. Will be better, the contrast between static distance viewing is too obvious. Large LCD splicing screen has irreplaceable superiority.
Three, the seams
Large LCD splicing screens have splicing gaps of different sizes, 5.5 to 1.7mm on both sides. After splicing, there will be a physical black border between the screen and the screen, which will affect the viewing effect when pictures are displayed on the entire screen. LED does not have this problem, no matter how they are spliced together, the LED display does not have black edges.
Fourth, the application scenarios are different
Large LCD splicing screens are mainly used in areas that require high-definition display, splicing and segmentation, such as product exhibition halls, conference rooms, news broadcasting stations, monitoring centers, etc., and LEDs are mainly used. It is used in outdoor plazas, shopping malls, conference lecture halls and other long-distance viewing areas.
Five, installation environment
Because the LCD itself is not waterproof, large LCD splicing screens are mainly used indoors, and LED electronic screens can be used in various indoor and outdoor occasions.
When we choose LCD splicing large screen or LED electronic screen, we can choose according to our application, viewing distance, installation occasion and other sizes. Both have their own advantages and disadvantages, and the competition is fierce. The large LCD splicing screen has developed rapidly in recent years and has become the biggest competitor of LED, especially the introduction of the seamless splicing LCD large screen, which fully reflects the high definition and seamless display. characteristic.
