With the continuous reduction of the dot pitch of outdoor LED display screens and the application of surface mount technology, the screen quality is more realistic and delicate, and the colors are 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 have emerged.

Outdoor small pitch usually refers to the LED display with a dot pitch of 5mm or less, while the conventional dot pitches appearing on the market today are usually 10mm and 8mm. Such a pitch will only have a clear display when viewed from a long distance. The effect often gives people a sense of oppression. The outdoor small-pitch pixel density is very high, and close viewing can also ensure the clarity of the picture, so as to achieve a "dialogue" with the audience, and the advertising content is transformed into the audience's active reception.
Outdoor small-pitch LED displays are vividly called "grounding gas". The shortening of the distance eliminates the unfamiliarity of the audience with the LED display, so that the information dissemination effect of the display can be greatly improved, which is more convenient for realization. Human-computer interaction can better display advertising creativity, user experience and product acceptance will also be better.
Although the advantages of small outdoor spacing are obvious, it is trapped by many factors, and many problems need to be overcome for large-scale popularization and promotion. First of all, although the advantages of outdoor small pitches are self-evident in terms of color and contrast display effects, it is well known that the more lamp beads used in a unit square, the higher the corresponding cost. As a result, the cost of the entire screen is higher, and the price has become a major problem that plagues the popularization and application of LED outdoor small pitches.
Secondly, outdoor small pitches generally have a small area, which cannot meet the large screen requirements of outdoor media for LED displays. This is mainly because the outdoor small-pitch manufacturing process is complicated. In order to ensure the service life and operating stability of the screen, it is often necessary to add protective glass on the outside of the screen to resist moisture, sand and dust. However, it is difficult to increase the area of the protective cover unlimitedly, and the existence of the glass cover will also cause the mirror image to be superimposed. In order to ensure the use of small outdoor spaces, it is imperative to peel off the outer protective cover. At present, only Shenzhen Bobangcheng has achieved "outer glass removal" for the first time, and has mature project cases in Shanghai, Hangzhou and other places.
Thirdly, the outdoor small pitch is a new LED display product, which has higher technical requirements. The high requirements for lamp bead quality, display packaging, waterproof and dustproof performance have discouraged many LED display manufacturers who want to get involved in outdoor small-pitch LED display.
Undoubtedly, small outdoor spacing has huge profits and a huge market, but it also has troubles from cost, social recognition and technology. The large-scale implementation of outdoor small spacing will take time.
