With the development of science and technology, LED technology is also developing continuously, bringing various conveniences to our lives, providing us with various life information, and benefiting us human beings.

As the current leader in the field of large-screen display, LCD splicing screen has continuously expanded its application field. At present, in addition to occupying the vast majority of the market share in security monitoring display, it is also rapidly infiltrating into various display fields, such as enterprise display platforms. , conference platforms in various occasions, advertising platforms in public places, etc. Although the LCD splicing screen has expanded its market share by virtue of its strong product strength, it also has certain defects.

With the continuous expansion of the application range of full-color LED display and the continuous expansion of application fields, people are getting higher and higher quality of LED full-color display. The full-color LED display has clear images, uniform colors and high brightness. With ultra-bright LEDs, you can still see clearly from a distance.

From a brightness point of view, these two stitching techniques don't have to worry about enough. Conversely, fine-pitch LED displays, known for their high brightness, suffer from excessive brightness. One of the main technologies of fine pitch LED displays is "low brightness". In contrast, LCD screens are more suitable for brightness levels and are suitable for applications with large displays. In terms of contrast ratio, the small-pitch LED is the highest, but from the demand side, the contrast ratio of the two technologies exceeds the actual display requirements and the resolution limit of the human eye. This creates a contrasting effect, where the quality of the two technologies depends more on software optimizations than hardware limitations.

From a technical point of view, LCD splicing screen is an extension of LCD technology. By industrial-grade processing of its LCD panel, it has reached the requirements of perennial start-up, and has high-stability display characteristics, and can be formed by splicing multiple screens. The large screen can achieve a variety of display effects, including multi-screen, roaming, splitting, etc. In addition, the brightness of the LCD splicing screen can reach more than 500cd/m2, the contrast ratio is as high as several thousand to one, and the color display is very rich. Regular resolution can also reach 1920*1080 display, and single-screen 16:9 display.

White balance effect is one of the most important indicators of LED display. In color science, pure white appears only when the ratio of the three primary colors red, green and blue is 1:4.6:0.16. If the actual scale is slightly different, the white balance will be off. In general, pay attention to whether the white is blue or yellow-green phenomenon. The white balance is mainly determined by the control system of the LED display, and the lamp beads also affect the color reproduction.

In terms of resolution (PPI) metrics, although fine pitch LEDs have been breaking through, they still can't compete with LCD video walls. Currently, only LCD screens can achieve 2K popularity on 55-inch monitors. In the future, there is hope and 4K can be popularized. LCD screen only. For fine-pitch LED displays, higher pixel density means that the difficulty of designing for stability shows an increase in the geometric base, and the pixel pitch is reduced by 50%, and the backplane density must be increased by a factor of 4. That's why fine pitch LEDs break through the 1.0, 0.8 and 0.6 bottlenecks, but only the root cause of products like 3.0/2.5 is the real mass application.

In addition to the powerful display function of the LCD splicing screen, the product itself has certain defects. These defects are mainly limited by the LCD technology itself, and the seam is the biggest focus. Since the LCD panel itself cannot achieve seamless display, there will be more or less black borders. The current smallest physical frame is 1.7mm. Although the seams have been reduced by technical means, they cannot be completely eliminated. It also affects its application space to a great extent. Like some high-end display occasions, many users have turned to LED fine-pitch products due to user stitching.

There are many types of full-color LED displays, including indoor and outdoor energy-saving, high-brightness, high-refresh, portable and other products. All walks of life have different requirements for LED displays. Therefore, when buyers distinguish the quality of LED displays and choose LED displays , To gather your own needs, whether the manufacturer's LED display products can meet your own needs to the greatest extent.

The color range is generally not the most concerned direction for video wall products. In addition to the application scenarios such as radio and television, the demand for color reproduction range has never been strict in the video wall market. From a comparative point of view, small-pitch LED displays are natural wide-color gamut products. Liquid crystal depends on what kind of light source is used. The above is the relevant knowledge of LED technology. I believe that with the development of science and technology, the future LED lights will become more and more efficient, and the service life will be greatly improved, bringing us greater convenience.
