With the development of science and technology, the application of rental LED display screens are becoming more and more widely. When we purchase large size LED screen, we must consider about the size, energy consumption, the environment, view distance, visual effects of the LED screens as well as other aspects. When building large size LED screens, what should the users and the LED screen rental service providers should do?
When choosing the size of LED screens for your event, there are three factors we should consider about: 1. The requirements of display content on the rental LED display screens; 2. The space of the event place; 3. The panel size of LED screen and pixel; For the outdoor rental LED display screens, the first thing is to determine the screen’s pixel. Then we should consider about the requirements of the display contents, space, installation position, view distance, etc. The longer the distance between the installation location and the audience area, the larger the pixel should be. However, the larger the pixel size, the lower the pixel resolution will be and the less content the LED screen can display. 4. Power Consumption and power source of outdoor rental LED screens; As for the power consumption of outdoor rental LED display screens, we should consider both the average power consumption and maximum power consumption. Average power consumption, also known as the actual power consumption is usually the actual power consumption. The maximum power consumption is the amount of power consumed during extreme conditions such as start up or full using. 5. Working environment and daily maintenance of rental LED display screens; LED screens installed in the open air will always suffering sunlight and rain, wind and dust, so their working environment are extremely bad. If the LED screens get wet or severe damped, it can cause short-circuit or even fire, and resulting in great loss. In addition, the LED screens may be damaged by strong lightning and magnetic. The working environment temperature is another factor which both the LED screen rental service providers and the users should concern. Because it may influence the LED screen’s heat dissipation and working stability. 6. Waterproof protection of outdoor rental LED display screens; Waterproof protection are another important aspects the outdoor rental LED display screens should pay attention to. Most outdoor use LED screens are with IP65 protection at least, some LED screens applied in water will need IP68 level.

LED screen industry has developed for about 20 years, it is now a matured industry field. LED screens have been applied into various industry fields. During the application of rental LED display screens, the installation work are always an important aspect. Normally, the LED screen rental service providers will send an engineer to your event place and help install the LED screens. But there are many works need to do before installing the screen.
The engineer from Glux Visual Effects would like to introduce you the main steps of rental LED display screens installing work. 1.Previous exploration work. This is an important work. The LED screen rental service providers needs to know about the event place, so that they can design appropriate installation plan according to the practical situation of the event place. Normally, they will analyze the size of the event place, your visual distance and visual effects demand, the environment, etc. 2.Number of LED screens, electricity and signal lines calculation. Before installation work, the engineer needs to know how much LED screens the event will need, and design the electricity wire and signal wires appropriately. 3.Supporting structure design. Whether standing installation or hanging installation is suitable for your event is determined by the practical situation at your event place. In addition, the number of LED panels needed for this rental LED screen and the weight capacity of the supporting structure should also be considered. If the total amount of LED panels are beyond the weight capacity of the supporting part, it will cause serious accident. Normally, the LED screen rental service will also provide the supporting part for the screens, and also the supporting part build up work. 4.Training work. Before the rental LED display screens start to work, the users need to know some basic knowledge about the screen’s using, installation, components changing methods, so that the users can know more about the LED screens and avoid problems from happening. Currently, China’s LED screen industry is dominating the world’s LED screen industry. After years of development, China’s LED screen technology and innovation are leading the world LED screen industry development. Rental LED display screen business is a newly appeared business type in recent years, and led a large popularity all over the world. However, during the development, the problems in China's LED screen industry is also becoming more obvious, such as product homogeneity competition, frequent price wars, brand missing, etc. These unfavorable factors not only seriously hindered the healthy development of this industry, but also increased the risk of LED screen enterprises.
Recalling the "blowout" developing period during the past 10 years, rental LED display screen industry has emerged more serious structural surplus problems, that is, middle and low homogeneous product surplus problems. The weak market demand and industry overcapacity makes the price war in rental LED screen industry become more and more fierce. The price cutting storm initiated by Absen has swept the entire industry, which also triggered a large-scale price war. Some insiders said that the LED screen industry will face a more difficult situation if the price war would not stop. For large enterprises with capital and scale, price reduction is an effective way to capture the market. For most small and medium-sized enterprises, they are forced to participate into this price war. Because of their own strength, scale are incomparable with those large enterprises the result is often heavy losses, damage. The result is heavy profit losses and damage. The frequent price war not only seriously compressed the profit margins of these small LED manufacturers, but will further affect the product quality. Some LED screen rental enterprises reduce the costs at the expense of products quality and service, which resulted a large number of poor quality products flooding the market. This will not only undermines the interests of consumers, but also disrupt the LED screen industry order, overdrawn the future development potential and Profit margins of this industry. In recent years, safety problems caused due to the quality of rental LED display screen are occurred frequently, these accidents have brought great danger to the personnel and the customer's economy. Obviously, for customers, the quality of LED screen is the most important. Therefore, to achieve real healthy and rapid development, technological innovation and research are still the company's foundation to LED screen rental companies. The LED screen enterprises should develop more advanced products to feedback the market, and form a well-known LED display brand to the public. Only in this way can they truly seize the market. Nowadays, the application of indoor and outdoor rental LED display screens are very common, while the safety problems are still serious. LED screen industry is a high-tech industry, this kind of hidden danger should be paid attention to and try to avoid this. It is now an urgent issue for the LED screen rental service providers to eliminate these hidden dangers. As for the security risks for LED screens, we need to focus on the following points:
1.Whether the metal structure’s weight capacity, and material is reasonable? Metal structure plays an important role for the safety of rental LED display screens, it is the supporting point of the entire screen. If the metal structure is not strong and unreasonable designed, it is easily to cause collapse accidents. From the cabinet material, carbon fiber, magnesium alloy, nano-polymer materials and other new materials can significantly reduce the weight of the LED screens’ cabinet and thickness. Thinner and lighter cabinet is not only conducive to product installation and maintenance, but also reduce the weight capacity for the support part, make it more safe. In addition, the excellent structural design can also avoid the collapse accident of the rental LED display screen. Rental LED screens are usually stacked high, or hoisting at a height near the cast members and audience, so the structural safety is the most important part during the design process. Because the installation time is short, it is not possible to set aside a long time to check whether the screens are installed solidly, so the LED screen rental service providers should check it quickly and carefully. 2.Power choosing; Poor power is easy to lead to combustion fire. If the power work overload of power supply (usually only 75% of the rated power supply) for a long time, or the power cord terminals and poor contact is not solid, these might be fire accident caused. 3.Designing and production technology; Outdoor rental LED display screens always working in high temperature environment. Therefore, their heat dissipation ability will be an important thing we should consider about when designing it. In addition, if the size of LED screens is too large, then there will be more heat dissipated. If the designing and production technique is not good, then there will be some safety problems caused. 4.External cause; Some LED screen rental service providers do not provide systematic training to their users, or the training is not good, then cause non-standard operation. On the other hand, if the regular maintenance or late maintenance is not timely and not meticulous, leading to in-detect anomalies dealing. In addition, the components choosing, whether should use flame retardant materials in specific occasions, high temperature conditions application, the cooling system design as well as other aspects will also influence the application of the outdoor rental LED display screens. In a certain sense, the lifespan of LED screens is determined by the LED chip’s lifespan. The lifespan of LED chip is usually defined as a period from luminescence intensity attenuation to the initial value of 50%. As a semiconductor material, it is often said that LED chips have 10 million hours of lifespan, but that is a assessment under ideal conditions. In the actual application, the lifespan of LED screens are not up to that much. Rental LED display screens have gradually appeared in the streets and dress up our city with different ways. But LED screen also has a lifespan, if there is no reasonable maintenance, it cannot be used for long time. Then what are the determining factors to the lifespan of LED screens? Here are the answers.
LED chip’s lifespan determines LED screen’s lifespan, but it does not mean LED chip’s lifespan is equal to the screen’s lifespan. When the rental LED screens are working, not every LED are working at full capacity. When the LED screen normally playing the video programs, the lifespan of LED screens should be about 8 times of LED chip’s, when the LED chips working with small current conditions, its lifespan can be longer. 1.The LED chips influence the lifespan of LED screens; LED chips are the most critical and most relevant components to the screen’s lifespan. For the LED chips, we should mainly considering the following indicators: attenuation characteristics, anti water and vapor permeability and anti-UV properties. If the LED screen rental service providers applied low quality LED chips into their screens, it will lead to lots of quality problems, also will affect the screen’s lifespan. 2.The production technology influence the lifespan of LED screens; The production process of rental LED display screens determines the screen’s anti-fatigue properties. The LED modules produced with low technology has poor anti-fatigue property. When the temperature and humidity changes, there will be cracks on the surface of circuit board, and resulting in reduced protective performance. As for most LED screen rental service providers, the accumulation of experience is very important, a factory with many years of experience in production process controlling will be more effective. 3.The matching components influence the lifespan of LED screens; In addition to LED chips, there are other components also influence the lifespan of LED screens: circuit boards, shell, switches, connectors, etc., if any component has quality problems, it may also shorten the screen’s lifespan. Therefore, the life of the shortest life of rental LED display screens is influenced by the components with shortest lifespan. For example, the LED chips, switches and shells have 8 years lifespan, but the protection performance of circuit board can only support its work for 3 years, then the circuit board may corroded after 3 years, then we can only get a 3 years Lifespan LED display. 4.The working environment influence the lifespan of LED screens; The lifespan of rental LED screens will also different in different application conditions. From the environmental aspect, indoor environment has smaller temperature difference, there is no rain/snow and UV influence; outdoor environment has larger temperature difference, wind, sun and rain damage. Harsh environment will aggravate the aging speed of LED screens. This is also an important factor affecting the lifespan of LED screens. We can see various kinds of rental LED display screen everywhere, applied for different audio visual events. Today, the engineer from Glux Visual Effects Tech would like to have a brief classification about them.
1.According to application environment -- Indoor and outdoor rental LED screens; Indoor rental LED screens are normally with smaller size (limited by the space indoor), they have small pixel pitch (1 mm to 5mm, some are less than 1mm). The view distance is shorter than outdoor use LED screens. Indoor use LED screens do not have waterproof ability. Small pixel indoor LED screens are more expensive than outdoor screens. Outdoor rental LED screens are normally with larger size. The LED screen rental service providers can help to build up dozens or even hundreds square meters according to your demand and space. Basically, the pixel pitch of outdoor use LED screens are larger than indoor ones, normally 5mm to 20mm (can be even larger). Outdoor use rental LED display screens have excellent waterproof ability, dust-proof ability. 2.According to color -- single color, double primary color and triple primary color rental LED displays; Single color LED screens can only display one color, normally red color. Double primary color LED screen are normally composed by red and yellow color. Since they have less color displaying ability, single color and double primary color LED screens are not very popular now. Triple primary color LED screens, can be divided into full color rental LED screens and nature color LED screens. Full color LED screen is composed by red, green(wave length is 570 nm) and blue color; nature color LED screen is composed by red, pure green (wave length is 525 nm) and blue color. Triple primary color rental LED screens can display all kinds of color we want. Most LED screen rental service providers can provide triple primary LED screens now. Actually, there are some other classification ways. For example, according to the installation ways, rental LED display screens can be divided into permanent/fixed installation LED screens and non-fixed installation LED screens. According to the cabinet material, they can be divided into metal cabinet LED screens and carbon fiber LED screens. When choosing LED screens for your events, it is better to choose according to your practical application environment, installation request, color request, budget, etc. If you are not familiar about LED screens, it is better to ask the LED screen rental service providers to give you some professional advice. In recent years, LED screen industry’s developing speed is getting slower and slower. One of the main reason is that the innovation ability of most LED screen rental service providers are not good. This is mainly reflected in high technological products and leading core products are limited, “Cloning” technologies and products are very common in the market. In addition, leading LED screen enterprises which can promote technological progress and enhance the overall industry developing level are few. Many LED screen factories put few efforts in R & D. More and more low quality indoor and outdoor rental LED display screens entering into the market.
In the early period, LED screen industry are developing rapidly. It is inseparable from the performance of technological innovation at that period. In the 1990s, every two years there will be leading-edge technology to lead the market mainstream products. In recent years, due to the lack of technological innovation, low-level product technology duplication, the market application environment and other reasons, price competition and a variety of non-standard competition behavior are happening more and more frequently. There are no standard price and quality requests for indoor and outdoor rental LED screens. The market goes complicated and chaotic. To truly improve the competitiveness of LED screen rental industry in the global market, we need to work hard and improve from the following aspects: First, strengthen publicity, expand the influence, improve the image and enhance the awareness of the society; Second, enhance the technology Level of indoor and outdoor rental LED display screens, shaping the new connotation of LED screen factories; Third, the government should format some representative enterprises with strong overall strength and large scale in this industry. Even though the technology in LED screen industry is high, but this industry are lack of product standardization, systematic machine design, reliability, standard manufacturing processes, standard testing and testing methods. Therefore, the LED screen industry should adjust the strategy and improve the innovation ability. Standardization of LED screen production and application needs to strengthen the working standardization of the display screen, also needs to perfect the device, the basic materials, etc. |
