In recent years, with the small-pitch LED display technology and the market gradually matured, its application in the field of indoor large-screen splicing is becoming more and more common. In particular, under the current rapid development of smart cities and security industries, the demand for indoor large screens in various cities has been increasing, and small-pitch LED products have also become popular all the time. Although the current price of small-pitch products is relatively high, mainly in the mid-to-high-end market, but under the trend of rapid growth of small distances and the gradual decline in prices, it still brings pressure to traditional indoor large-screen splicing products such as LCD and DLP. . In the future, the large-screen splicing market in the interior will be dominated by people. Let us analyze them one by one.
Performance PK: excellent display with small pitch, high LCD market acceptance
Also in the indoor large screen area has a good record, small pitch, LCD, DLP products their own characteristics in the end what is it? Here we compare one by one.
As mentioned earlier, the small pitch is very eye-catching in terms of display performance. Because of the fundamental difference between the light emitting principle and the structure, the small-pitch LED products can not only achieve seamless splice, but also have a very wide color gamut and excellent color performance. These are not comparable to DLP and LCD, and the response speed is fast. Problems such as ghosting and smearing are almost a rewrite of the large screens of the past.
DLP is stable. In terms of stitching gaps and mirror reflections, they perform better than LCDs, but they cannot be compared with small pitches. Compared with LCDs, they have better resolution and heat generation than small pitches. Overall, DLP's overall performance is "moderate", and except for the brightness, the basic performance is good.
The advantages and disadvantages of LCD are also more obvious. The biggest disadvantage is that the splicing gap is too large. Even a 1.8 mm splicing seam is visible to the naked eye and affects the overall visual performance. Secondly, the screen is affected by external light, and the problem of easy reflection also needs to be solved. However, it still has a great advantage in terms of resolution, heat generation, maintenance, etc., and the indoor display does not require high brightness. In addition, the price is low and the maintenance cost is not high. The advantage of the LCD in indoor display is still more obvious. Large screen splicing market in the mainstay.
Market "changes face": aggressive pitch performance, DLP sluggishness
2016 was the first year of the outbreak of small-pitch LED products, and in 2017 it took a steady pace toward a wide range of applications and succeeded in gaining a spot in the indoor display area. According to data released by the research institutes in the first half of 2017, China's large-screen splicing market shows that LCD splicing sales amounted to 2.16 billion yuan, accounting for 48%, up 33.6% year-on-year; small-pitch sales amounted to 1.59 billion yuan, accounting for 35% of the growth. 73.8%; DLP splicing was 730 million yuan, accounting for 16%, with a growth rate of -8.6%.
It can be seen that in the field of large-screen splicing, LCD still occupies a major position, and maintains a considerable growth rate; the current share of small-pitch products is not high, but over 70% of the alarming growth rate has been foreseen, and its future market expectations are considerable; DLP not only does not sell well, it also shows a negative growth trend, and the market outlook may be worrying.
This kind of performance is not without reason. After many years of market education, the popularity of LCD is much higher than that of the other two, and the price is close to the people and more acceptable to the market. The small spacing attracts a lot of attention due to its vivid and seamless features. In contrast, DLP is not well-recognized, and its performance is flat. Both the low-end and high-end markets are difficult to match with the former.
Small gaps in the high-end market to shine, hidden defects can not be underestimated!
In the past two years, the small-pitch products have been widely used in high-end large-screen areas, whether they are displayed at various summits, conferences, or in large command centers and other areas. They even started to enter the cinema as movie screens. . These are undoubtedly based on the display effect of good picture integrity and strong color expression in small-pitch products, but before rejoicing in this, we still need to focus on the application of small pitch in indoor applications, as well as obvious defects.
The first is the brightness problem. Almost unaffected by sunlight, light, and other external light, LED displays have become the dominant player in outdoor areas, and such features have been placed in indoor areas and are subject to high brightness. Especially in the field of security monitoring, staff need to face the screen for a long time. Excessive brightness is not a good visual experience.
Followed by stability issues. For a traditional LED display, the dead light rate is generally controlled to be less than one ten thousandth. However, for a high-density, small-pitch screen, the one-tenth probability obviously cannot meet the picture requirements, and the lower dead-light rate becomes inevitable. The requirement, coupled with the fact that small gaps are more used in high-end areas, imposes stricter quality requirements.
The last is the cost issue. The purchase cost of the small pitch itself is higher than that of the LCD. The heat dissipation cost and the power cost of the LED display are higher than those of the LCD and the DLP. The superposition of the two causes the overall use cost to remain high, resulting in a small pitch LED screen. There is greater resistance to enter the mid- to low-end market with huge demand.
Although the current growth rate of small gaps is relatively fast, this is based on the fact that its original sales base is small, and whether small gaps can continue to grab the share of LCDs whose market performance is still good is a performance-price competition. This still needs to rely on the unremitting efforts of small-pitch manufacturers.
