What is the difference between LCD splicing screen and small-pitch LED screen? At present, the commonly used splicing large-screen display products on the market include LED screens, LCD splicing screens, projection and DLP screens and other equipment. Compared with traditional projection, DLP screens and other equipment, LCD splicing screens not only display better, but also cost-effective. Very high, and the market share in most of the security monitoring and display fields is also getting bigger and bigger. With the development of LED display technology, the dot pitch can now be below p1.0, which is not much different from the 0.88mm LCD splicing screen, so the display clarity has also been greatly improved, but from the actual From the application point of view, although LED screens have a higher market share, LCD splicing screens have unique advantages.

  1. High-definition resolution display

  We all know that the LCD splicing screen is a high-resolution product. The resolution of each screen can reach 1920*1080. After four pieces of splicing, it can also play 4K video sources, which can meet the current mainstream video source playback requirements. Although the resolution of LED screens has been greatly improved with the introduction of small-pitch products, if you watch from a close distance, there will still be some mosaics in displaying some text and other content, which is still not compatible with LCD splicing screens. In comparison, a small-pitch product costs at least tens of thousands of yuan per square meter. Compared with LCD splicing screens, the overall investment cost will be greater.

  Second, the technology is stable, basically no after-sales

  The LCD splicing screen adopts the principle of back-emitting display technology. If the entire LCD panel is not impacted or squeezed by external force, there will be basically no damage, so the service life can reach more than 60,000 hours, and the small-pitch LED screen We all know that the product is composed of rows of lamp beads. Due to different chip brands and different packaging manufacturers' technologies, the entire screen will have a certain dead-light rate, and there will be small black dots or small red dots when displayed. At this time, the manufacturer is required to repair or replace, and this frequency is very high, so from this point of view, the after-sales rate of LED screens is higher.

  Three, display function

  Regardless of whether it is an LCD splicing screen or a small-pitch LED screen, the fundamental principle is a large display. Its display function is mainly realized by the back-end control equipment. The advantage of the LCD splicing screen is that each screen is a unit, that is, the unit can be realized. Within the split display, you can also achieve cross-screen display, superimposed roaming and other effects, which is especially suitable for some command center occasions; while the small-pitch LED screen is not so powerful in the display function, although it can also achieve a certain split and splicing Wait for the display, but neither the number of divisions nor the roaming function are as powerful as the LCD splicing screen.

  Although the LCD splicing screen has obvious advantages over the small-pitch LED screen, from the perspective of the installation environment, the LCD splicing screen is only suitable for indoor use, because it does not have the waterproof function, and the LED display is different, it can be waterproof Function, can be widely used in outdoor splicing large screen, as a poster publicity display.
