Along with the continuous reduction of the distance between the outdoor LED display screens and the application of the surface-mounting process, the screen quality is more realistic and delicate, and the color is more uniform, and the display effect is clearer. In order to further narrow the distance between the display and the viewer, outdoor small-pitch products came into being. 
Outdoor small spacing is usually an LED display with a dot spacing of less than 5mm. The conventional point spacing that is now on the market is usually 10mm and 8mm. Such a spacing will only be clearly displayed when viewed from a distance. The effect often gives people a sense of oppression. The outdoor small-pitch pixel density is very high, and the close-range viewing can also ensure the clarity of the picture, thereby achieving a "conversation" with the audience, and the advertising content is converted into an active reception by the audience.
The outdoor small-pitch LED display is aptly called “grounding gasâ€, and the shortening of the distance eliminates the strangeness of the audience to the LED display, so that the information transmission effect of the display can be greatly improved, thereby making it more convenient to implement. Human-computer interaction can better display advertising creativity, user experience and acceptance of products will be better.
Although the advantages of outdoor small spacing are obvious, but suffer from a variety of factors, widespread popularization still needs to overcome many problems. First of all, although the outdoor small spacing is in terms of color and contrast display, the advantages are self-evident, but it is well known that the more the number of lamp beads used per unit square, the higher the corresponding cost. In this way, the cost of the whole screen is higher, and the price becomes a big problem that plagues the popular application of LED outdoor small pitch.
Secondly, the outdoor small spacing belongs to the LED display new product, and the technical requirements are relatively high. The high requirements for lamp bead quality, display package, waterproof and dustproof performance have discouraged some LED display manufacturers who want to get involved in outdoor small pitch.
Undoubtedly, the small outdoor space has great profits and huge market, but it also has the troubles from cost, social recognition and technology. The outdoor small spacing needs to work hard to overcome these problems, and it is just around the corner.
