1. Reliability
For a product with a 2.0-point pitch, approximately 250,000 three-color lamp beads are used per square meter; for a product with a 1.0-point pitch, as many as one million lamp beads are used per square meter, and the craftsmanship of these lamp beads must be highly stable and consistent. One of the lamp beads has a defect, which often causes a splicing board with tens of thousands or hundreds of thousands of lamp beads to become "inferior products." Compared with the traditional outdoor LED display, the indicator requirement of the "failure rate" of the small pitch on the lamp beads has changed from the previous "one in 10,000" to "one in a million."
2. Technical difficulties
Among them are: the first line is dark, gray scale jump, low gray color cast, uneven gray scale, high contrast degradation, board card. In addition, how to eliminate moiré, eliminate caterpillars, reduce the rate of dead lights, and achieve a "low brightness, high gray, and high brush" display effect?
Three, service
With the shrinking of the dot pitch, the number of lamp beads has increased significantly, which has put forward higher requirements and greater challenges for the services of small-pitch suppliers.
4. Price and profit
In the past two years, the price of small-pitch LED screens has fallen sharply, from about US70,000 per square meter to about US30,000; compared with traditional outdoor large-pitch screens, the gross profit of small-pitch LED screens was once from early 2013 to mid-2014. More than twice the former, profit declined in 2015.
Five, application
The advantages of small-pitch technology have opened up new opportunities for indoor applications of LED screens, making them a strong competitor for rear projection (DLP) splicing and liquid crystal (LCD) splicing. The current applications are mainly concentrated in the government, military, and public services, and gradually penetrate into the commercial market-command and dispatch, virtual simulation, indoor digital signage, sports and cultural performances, etc. The breakthrough in the home market is still "zero".
Six, market segments
Small-pitch advertising machines, small-pitch TVs, and small-pitch rental screens have sprung up.
Seven, the market
The industry concentration in 2015 has declined compared to 2014. In addition, an interesting phenomenon in 2015 is that traditional rear projection and LCD device manufacturers, such as Samsung, Delta, Panasonic, Planar, Philips, Avis, Vitron, GQY, Multimedia, Christie, Barco , NEC, have poured into the small pitch market. In 2015, the number of small-pitch LED companies with good sales scale increased to more than 10 brands, and the total number of market participants reached 30. The small-pitch industry has gradually formed a tadpole-shaped market structure: the head is large and the tail is also long.
Products with 1.2 to 2.0 pitch occupy more than 98 percent of the small pitch sales market. IHS research shows that China currently accounts for almost 50 percent of the global market share of 1.9mm and below products.
8. Outdoor small spacing
For outdoor small spacing, in terms of current market demand, the small spacing market application of P4-P10 is still very extensive. P4 is a critical point. If you continue to do so, you will face two problems: 1) The technical difficulty is large, including waterproof performance, etc.; 2) Whether it is necessary.
9. Opportunities and prospects
Indoors, it will continue to compete with DLP and LCD in the commercial market and further develop market segments; outdoors, it will replace some of the in-line products.
10. External challenges
1) Facing the challenge of emerging display products, such as OLED;
2) The upstream links, especially the fluctuations in the price of lamp beads, will have a certain impact on the small-pitch market structure.
