हाल, China has become the world’s largest exporter, while the United States, the European Union, Japan and ASEAN have become China’s most important export markets. China’s domestic demand has been depressed for many years, especially in this year’s new crown outbreak, which has made our exports strive for further improvement.
Then, with the outbreak of the epidemic in the United States, the European Union, Japan and ASEAN, the impact on China’s LED display panel export will not be underestimated, especially for export-oriented enterprises such as the southeast coast, which will be a huge challenge.
According to the relevant report of Mingming bond research team, the export growth rate dropped sharply due to the dual factors of epidemic holidays. This year, due to the influence of the Spring Festival, China released the foreign trade data from January to February for the first time. In January February, China’s export value in US dollars decreased by 17.2%, significantly lower than the previous value. From the perspective of reasons, the rapid fermentation of the new epidemic situation in China from January to February and the extension of the Spring Festival holiday are the main reasons for the decline in exports in the first two months of this year. In February, in order to control the new epidemic situation, a large number of enterprises shut down their factories and stopped production. Some enterprises had to face the situation of order cancellation or delayed delivery.
Export is limited and the resumption of work is delayed. The epidemic situation has a significant impact on exports, and many export orders are difficult to complete on schedule. Since the outbreak of the epidemic, धेरै 120 countries have taken entry control measures against Chinese citizens, र 24 countries and regions have imposed restrictions on China’s trade in goods due to the epidemic. Due to the need of epidemic prevention and control, the resumption of work nationwide was delayed after the Spring Festival. Although the national enterprises began to resume work and production after February 10, the progress was very slow, and the rate of returning to work did not gradually improve until the end of February. As of February 26, the return rate of small and medium-sized enterprises in China was 32.8%, and the rate of workers returning to work in 15 cities in the East was only 25.6%. As a result of the epidemic, the production of enterprises slowed down, and many export orders were difficult to complete on schedule, leading to a significant decline in export growth from January to February, which was expected.
Affected by the overseas epidemic situation, it was difficult for export to improve significantly in March. After the spread of the overseas epidemic in March, it not only affected overseas demand, but also affected the global supply chain. China is the most important link in the global supply chain. त्यसैले, the second round impact of the spread of overseas epidemic on China’s import and export may be greater than the negative impact of shutdown and production stoppage caused by domestic epidemic situation. The growth prospect of China’s export trade this year may not be optimistic. In February, the new export order index and import index of the manufacturing industry were 28.7% र 31.9% respectively, which were significantly decreased by 20% र 17.1% compared with the previous month, indicating that the import and export situation may be poor in the near future. त्यसैले, it is expected that the trend of negative growth in exports may continue in March.
I believe that many friends are choosing waterproof cabinet and simple cabinet for LED display screen, which is better? I don’t know which is better. So how to distinguish, because LED display often works outdoors, it is often affected by wet and rainy weather, so outdoor LED display must use waterproof box, in order to better protect the LED unit board from rain and moisture. For indoor LED display screen, due to its indoor work, the waterproof requirements are not high, and the use of simple box is enough to deal with the protection problem. Here is to take you in-depth interpretation of the difference between the waterproof box and simple box of LED display screen:
waterproof LED displayscreen is divided into simple box and waterproof box. The only difference between simple box and waterproof box is that the simple box has no back door and fan. The function of simple box is to reduce weight and reduce cost.
Whether it is a simple box or a waterproof box must go through the edge wrapping process, and the stainless steel edging around the LED display screen can completely achieve the waterproof effect. The conclusion is: the simple box structure is simple (simple box can also achieve waterproof effect); the waterproof box should be fully closed, and the interior of the box will not enter water under normal outdoor rain.
Now many outdoor LED displays are made of simple box, because the cost of sealed box is high, and the final waterproof effect is the same as the simple box, so people mostly choose simple box.
And LED display box began to thin, easy to dismantle the direction of development, but from a professional point of view, not all closed, light can play a waterproof effect, just like your computer case, the box structure only plays the role of dust, foreign matter, if large area of water, it will cause internal damage, and the space is too small, not conducive to heat dissipation.
Conclusion: if you want a longer service life of LED display, you must know how to properly use the LED display box. Reasonable use of the box can not extend the service life of the display screen, but also avoid the cost caused by improper selection of the box.

For the majority of users, whenbuying led rental displayor LED lamps and lanterns, they usually feel that the price is very pressure, especially when buying led in large quantities. त्यसैले, when many people have the demand of LED display rental, the first choice is not to buy, but to rent. हाल, there are many businesses providing LED display rental service. Is the rental price of LED display screen very expensive?
In fact, at present, the rental price of LED display screen is not very expensive. Moreover, the rental price of LED display depends on the type of led you rent in the process of leasing. उदाहरणका लागि, the rental price of LED display screen and LED lamps is completely different. There is also the size of the area and the length of the service cycle will determine the price of more or less. So when you rent the LED display screen, you can first understand the basic market situation. When you have a better understanding of the market situation, you can rent it. कमसेकम, you can avoid being cheated.
For the rental of LED display, will the prices given by different businesses be different? According to the truth, it is true, but even so, each business in the development of LED display rental prices are in accordance with the industry standards to price, so you do not need to deliberately worry about processing problems, as long as it is in line with the market, and you can give the rental price of LED display, then you can rest assured of the rental. अवश्य पनि, we also need to pay attention to the quality and performance of the leased products to avoid problems in the use process.
With the continuous development of LED display technology, transparent LED displaytechnology has been widely spread and recognized by the public. Transparent display screen is also widely used in commercial buildings, प्रकाश, smart window and other fields. So, when we choose transparent LED display, how to determine its size and shape?
From the perspective of display effect, the conventional size ratio of LED display screen used for playing video is generally 4:3 र 16:9 or close to the ratio. The size of transparent display screen is generally made according to the site size and aesthetic degree. If it is a wall, it depends on the wall position and the size of stairs, try to make it bigger, even if the resolution is low, it should also choose the area as large as possible.
From the technical and aesthetic point of view, curtain wall led transparent screen in China is basically square, a little uniform, it is suggested to make some creative and attractive shapes. उदाहरणका लागि, arc, cylinder, triangle, sphere and so on, strange design will attract more people’s attention! The specific shape design should be combined with the actual environment to consider, to design according to local conditions.
अवश्य पनि, when you don’t know how to determine the size of transparent display screen, there are many standardized transparent screen sizes for you to choose. The common sizes of transparent LED screen are 1m * 1m, 0.5m * 1m, 1.5m * 1m, 2m * 1m, 2m * 2m, आदि, and the former two sizes are the majority. You can seamlessly splice the ideal size through the standardized transparent screen box.
The same is true for the shape selection of transparent LED display screen. The owner of the shape design can listen to the opinions of professional architectural designers and seek reasonable solutions from the overall aesthetics and design style of commercial buildings. When the owners don’t know how to determine the shape of the transparent screen, they can also consult the LED transparent screen manufacturers, and determine the desired effect by looking at the effect of abnormal transparent screen or conducting field project investigation.
People inShenzhen LED displayindustry all know that black light has two obvious advantages: high contrast and high fidelity color compared with ordinary outdoor white light display. The black LED display screen refers to the outdoor display screen made of LED light with full black shell bracket.
LED display screen is made of light-emitting diodes (LEDs) as pixels. Light emitting diodes (LEDs) are assembled by plastic supports and light-emitting chips. In the early stage, the brightness of light-emitting chips was not high, so the plastic supports were made into white bowls to enhance the focusing and reflection, so as to ensure that the chips with low brightness can achieve a brighter effect. But if we want to express black and gray, its LED color is not only white, but also participate in the color of electronic display screen, which leads to color distortion. The brightness and luminous efficiency of the black light chip have been greatly improved, and it is no longer necessary to sacrifice the contrast to make up for the lack of chip brightness.
The full black shell bracket of black light can maximize the contrast of outdoor LED display screen. High contrast makes it easier to display vivid video images, and supports all levels of colors, making the color more realistic. Contrast has a greater impact on the dynamic video display effect. Since the light to dark conversion is faster in dynamic images, the higher the contrast, the easier it is for human eyes to distinguish such a conversion process. एउटै समयमा, the black light adopts a unique matte technology, with unique surface light, no reflection, softer light and no glare, so as to solve the outdoor glare problem, reduce the interference of stray light, and improve the quality of the screen display, and the color is more real and clear. Black light is another transcendence of outdoor LED display technology, which not only brings the improvement of outdoor display screen, but also brings the upgrade of display energy-saving technology, lower power consumption, energy-saving and environmental protection.
Since the beginning of this year, all kinds of safety accidents of LED display screen have been common, In the case that people’s understanding of LED display is not thorough enough, it is more necessary for enterprises and people to lead by example, inform people of the safety of LED display screen, and eliminate the potential misunderstanding of LED display screen insecurity. On the evening of August 31 local time, a German open-air music festival was hit by a strong storm, blowing down an LED display on the stage, injuring 28 people at the scene. This is not the first time such accidents have occurred this year. 7 र 12, a bank led display screen because of the installation is not firm and fell, hit the child walking under the screen. The types of security incidents are different, but it is true that after a short time, the LED display screen again occurred safety accidents. Even if it is not a product quality problem, but the endless safety accidents, still hit people’s confidence in using LED display, and make people question the safety performance of LED display. Although the festival’s accident has nothing to do with installation, it is also alerting end users to strengthen the firmness ofLED display screen installation, reduce the impact of bad weather on LED display screen, and enhance the safety of LED display screen, so as to avoid hurting the masses.
LED display industry has a long history of development, but its security content problem started late, has no time to take into account, until nearly two years, the content security issue was proposed by the industry, and the content security was discussed and developed. On August 28, the Ministry of industry and information technology and other departments issued guidance on strengthening the industrial Internet security work, and made clear the goal of initially establishing the industrial Internet security system by the end of 2020. As one of the subdivided fields of Internet security, the issuance of this opinion is undoubtedly an official propaganda to strengthen the content security of LED display, which represents the strict investigation of LED display content by various departments in the future, and also represents that the content security problem of LED display screen is forming a system. According to industry insiders, in addition to the recent Hong Kong incident and the 70th anniversary of the founding of the people’s Republic of China in the near future, government departments will strengthen the content security of LED displays. This year will be a major turning point in the history of content security.
यद्यपि, some domestic enterprises have already developed mature control systems, and set up dual secret keys through mobile app to ensure that content control does not fall into the hands of others. Moreover, real name authentication is required when the app is used, so the relevant departments can accurately find the sender and punish the sender when the event occurs. LED screen enterprises can refer to and purchase products to enhance the security of LED display content. With the promotion of the country and the industry, the future led content display will be able to develop at full speed and become one of the key directions of the industry development.
From the above analysis, it can be concluded that the safety of LED display screen is not promoted by one enterprise or enterprises in a certain field, but requires the cooperation of the whole industry chain of LED display screen. The upstream manufacturers need to strengthen the quality monitoring, and the downstream end users need to strengthen the supervision to maintain the safety image of LED display screen.
I believe that many people are not unfamiliar with outdoor LED outdoor display, after all, this is a simple common sense. Many users come to buy LED outdoor display screen. They don’t know much about it. Most of them are for their own company or their own customers. So they will ask a lot of questions about LED display screen before consulting. Because in today’s society, there are many kinds of LED display screen products, but generally speaking, as long as it is used for outdoor display point spacing is relatively large. So what type of LED outdoor display screen is most suitable?
In the first two years, the common models of outdoor LED display screen arep4.81 outdoor led screen, P5, P6, p6.25, p7.61, P8, P10, p12, P14, p16, P18, P20, P25. यद्यपि, with the improvement of R & D capability of each LED display manufacturer, as long as the display screen with point spacing greater than p2.5 can be used outdoors. अहिलेको समयमा, I believe that many people will be curious, living in so many types, so how should we choose? Users who do not know can refer to the following points:
1、 According to area: The playing area is less than 20 वर्ग मीटर. It is recommended to refresh the outdoor screen with p2.5-p5 HD. It is recommended to use p5-p10 LED outdoor full-color display screen with an area of 30-100 square meters and a viewing distance of 10 मिटर. It is recommended to use a large LED screen between P10 and p16.
2、 According to the distance: We all know that P represents the distance between pixels, and the value after P mainly refers to the distance between pixels of display module, which is commonly referred to as point spacing in LED industry. And the smaller the distance between the points, the higher the unit pixel, the clearer the display screen, and the more suitable for close viewing. त्यसैले, for LED outdoor display, if the distance is relatively close, Deloitte Rito recommends using p2.5 to p12, or p15 for farther distance, and p16-p25 for further distance.
If the area is more than or equal to 100 square meters and the viewing distance is more than 30 मिटर, it is recommended to use the display screen with p16 or above. Because the display screen above p16 is suitable for customers who do not require high definition and large display area, and can display simple images and video images in the distance. साथै, one point is: the farther the viewing distance is, the larger the screen area will be. If the clarity requirements for the display screen are relatively low, you can choose the display screen with large spacing.
हाल, SMD display screenused in the market has become a mainstream mature product, among which the indoor LED small space display screen is widely used in conference room, court, Public Security Bureau, procuratorate, command center, टिभी स्टेशन, आदि. एउटै समयमा, channel sales mode has been widely used in shopping malls, रेस्टुरेन्टहरू, विद्यालयहरू, public construction and other places. So how to strengthen the protection level of LED indoor display?
For the general LED indoor display screen, when the product is delivered, it is in the state of zero fault, but after a period of use, the light will be broken and the column will be on, and the light will be dropped due to the accidental collision; In the installation site environment, sometimes there are unforeseen or unsatisfactory scenarios. उदाहरणका लागि, the temperature difference of air conditioner tuyere short-distance direct blowing causes large area of bad points, or the site environment is too humid, resulting in the bad point rate of the screen rising day by day.
For the indoor small space industry which has passed the inspection for half a year, how to solve the display screen problems caused by water vapor, dust, bump, and broken lamp rate, and improve the product quality and reduce the burden and cost of after-sales service are the problems that the manufacturers of LED indoor display screen want to solve.
Figure 1. Bad short circuit and column lighting of LED display
त्यसैले, in order to effectively solve the mentioned problems, the so-called surface coating solution is produced.
This solution is based on the current indoor surface mounted LED display, and the equipment can be directly combined with the existing SMT surface mount production line, as shown in Figure 2.
Figure 2. Schematic diagram of surface coating equipment (lamp surface)
The process is to cover the surface of the lamp board made by SMT surface mounting process after 72 hours of aging process to form a so-called protective layer, which can wrap the conductive pins and isolate the influence of moisture and moisture, as shown in Figure 3.
For the LED display products with general protection level of IP40 (ipxx, front x dust-proof and rear x waterproof), it has the advantages of effectively improving the protection level of LED light surface, providing anti-collision effect, avoiding the occurrence of lamp dropping and reducing the whole screen bad point rate (PPM). हाल, this kind of solution has met the market demand, and the production is mature, and it will not excessively increase the overall cost burden.
साथै, the protection process on the back of the printed circuit board (PCB) maintains the three proofing paint protection process used in the past (as shown in Figure 4). साधारणतया, the protection grade of the back of the circuit board can be improved by coating the surface of the integrated circuit (IC) to form a protective layer, so as to avoid the failure of the integrated circuit components of the driving circuit.
For the indoor use of LED display module, such a solution can effectively prevent the occurrence of failure points caused by moisture and dust by wrapping the exposed electrical conductive pins. एउटै समयमा, it can provide protection against collision. हाल, the surface coating solutions on the market include gob display screen, AOB display screen, आदि.
Production has become a topic of general concern for many LED display companies, and the following question is that many customers are concerned about the question of whether the full color displayprice of LED wallwill rise during the epidemic period.
Recently, in the semiconductor field, the top three chip resistance manufacturers in the world, such as Guoju, housheng and wangquan, have successively sent out the information of resistance price rise, with an increase of more than 40%. Guoju’s supply chain pointed out that since March, Guoju has offered 50% र 70% को 80% of MLCC and r-chip respectively. LED industry supply chain end including electronic components, packaging materials, labor, logistics, आदि. are all showing signs of price rise.
Led full-color display industry will continue to raise the voice of the price, from the upstream chip factory, midstream packaging plant to the downstream application end, the major manufacturers are keeping a high degree of attention to the market price rise. The latest news of the industry is that the manufacturers can’t get the latest news.
About the LED full-color display price rising sound, the industry has never stopped. In recent years, under the influence of the national supply side reform, the state has vigorously promoted the policy of “three elimination, one reduction and one compensation” for five major tasks of capacity reduction, inventory removal, deleveraging, cost reduction and short board improvement, as well as many factors such as relevant environmental protection and monetary policy. The prices of raw materials have generally risen, and the prices of many industries such as Wujin, chemical industry and plastics have risen many times, and the LED full-color display screen involves semi-conductor Body, hardware, plastic and other fields are extremely sensitive to market price fluctuations.
यद्यपि, despite the rising production costs and labor costs, the price of LED full-color display screen did not rise but fell, showing a continuous downward trend. We say that led full-color display screen is an electronic product, which follows “Moore’s law”, and the price drop is an inevitable trend. यद्यपि, affected by the epidemic situation, if raw materials usher in a new round of high price rise, and the supply chain of LED industry is tense, can our LED display price still maintain the current level?
In 2019, in the case of rising prices of raw materials and production and operation costs, some enterprises have increased the prices of individual products. Most of them keep the prices unchanged through internal digestion and cost saving, so as to avoid the loss of old customers. साथै, some enterprises “go against the trend” and make an amazing move of price reduction and promotion.
From the perspective of the whole LED industry chain, the product prices of upstream LED chips and midstream LED packaging have been in a downward trend in recent two years. In addition to the continuous overcapacity and the sluggish downstream demand, the profit space has been greatly compressed. In 2020, if the price of raw materials rises explosively, LED chip and package manufacturers will undoubtedly face greater pressure. Once the price rises, it will be transmitted to the downstream application end. And in the past two days, the industry has been the rumor of rising prices of display screens.
No fire without wind, no wind in a hole. The price rise of LED full-color display screen this year will be a big probability event. And this for the majority of LED display enterprises, is no different from the icing on the cake!
विगतमा, LED display manufacturers can reduce product costs by optimizing product structure, simplify production process as much as possible, reduce labor costs, and expand the output of enterprises to resolve the impact of price increase. Through this internal digestion, the display price remains unchanged. यद्यपि, affected by the epidemic situation, whether LED display can offset this pressure through internal digestion this year has to be questioned.
हाल, the resumption rate of LED display enterprises is far lower than that of upstream and midstream enterprises. There are no orders and insufficient cash flow, which are the real difficulties faced by most of our small and medium-sized display enterprises!
This round of price increase of raw materials is mainly affected by the epidemic situation and is the response of the market in a short period of time. The manufacturers of LED chips and packaging in the upper and middle reaches are likely to be more willing to raise prices, while most of the enterprises of LED display application screen are keeping a high degree of vigilance and attention.
Although the domestic epidemic situation is gradually under control, the current epidemic situation has spread in 51 countries in six continents, and the global pandemic trend is obvious. No one can accurately predict when the LED full-color display market will return to normal in the future. How to raise the price of LED full-color display enterprises in the face of a severely frustrated market?
For the vast majority of small and medium-sized display enterprises, surviving is the biggest and only goal at present! But it is undoubtedly a very simple and crude way to deal with the pressure by increasing the price. This also reveals that our enterprises are still limited to products, the operating profit level is low, and has been on the warning line for a long time. त्यसैले, it is easy for us to panic about the price rise of raw materials.
In any case, this price increase is the result of the imbalance between supply and demand in the market, which is greatly affected by the epidemic situation. Even if there is a price rise, it is also short-term. Once the epidemic situation is over, the market will gradually return to normal level, and LED display enterprises need not be too nervous.
