.During the application of LED screens, especially outdoor rental LED display screens, they may get dirty after using for a long time. The daily maintenance work is important. Some people know about the maintenance method, but the cleaning work are not very familiar to them.
Before clean up the screens, the following steps are needed: 1.Turn on the outdoor rental LED display screens, check which part of the screen has dirt; 2.Turn off the screen and check the LED screen’s surface; by the above two steps, we can mainly find out the dirt. Actually, we should also pay attention if the surface of LED screens is broken, and check the Actually, the most difficult and strict clean up work to outdoor rental LED display screens is to clean up it surface. Also, we need to check the waterproof ability of the screens we will clean, make sure their waterproof ability is still good. Normally, these clean up work are done by your LED screen rental service providers. They have professional engineers, and they are familiar with their screen’s characteristics. Unprofessional clean work may damage the screens and influence the screen’s application. There are two aspects need to pay attention to before clean the screens: 1.Cut the electric wires before cleaning, make sure the safety of engineers; 2.Choose appropriate and high quality cleaning fluid. Normally used cleaning fluid including electrolyte, highly purified distilled water, antistatic agent, etc. The engineer should choose different cleaning fluid to clean up different dirt, make sure the outdoor rental LED display screens are not damaged during the cleaning work. Most outdoor screen rental service providers will take 3 steps to finish the cleaning and maintaining work: 1.Dust collection. Use dust collector to clean up the dust first; 2.Wet cleaning. Pay attention: do not pull the cleaning fluid directly onto the surface of your outdoor rental screens. Pull few fluid onto the cloth and wipe gently towards one direction. We can also use the soft brush on the dust collector to clean up the dirt. 3.Drying. Use dust collector to soak up water on the surface of screens, make sure there is no water and dust left on the surface of LED screens.

By now, we have successfully provided our outdoor rental LED display screens to many famous Olympics and sports games opening and closing ceremonies, including 2008 Beijing Olympics Opening Ceremony, 2013 Asia Youth Olympic Games Opening Ceremony, 2014 Youth Olympics Opening Ceremony, 2011 Summer Universiade Opening Ceremony, 2010 Youth Olympics Opening Ceremony in Singapore, 2011 11th European Youth Olympics Opening Ceremony, etc. Apart from the Olympics and sports game opening and closing ceremony, Glux’s outdoor rental LED display screens also have been applied into various stadiums all over the world. As an indoor and outdoor screen rental service provider, Glux have successfully provided LED screens for many sports events. As we all know, LED screens can be divided into single color LED screens, double color LED screens and full color LED screens. This article will take Glux’s outdoor rental LED display screens as an example of full color LED screens, and discuss about the difference of single color LED screens and full color LED screens.
1.Their structures are different; Glux’s full color outdoor rental LED display screens are made up of LED modules with three primary colors (red, green and blue). These three colors can make 16,777,216 kinds of colors totally. However, single color LED screens is made up of single color like white, blue, red, black, etc. They can only show one color. Nowadays, more and more LED screen rental service providers are using full color LED screens. 2.Their visual effects are different; Glux’s full color outdoor rental LED display screens can realize all kinds of colorful pictures and videos with high definition. They are mainly used for video displaying. While single color LED screens can only display one color, normally text and simple single color pictures. Full color LED screens are much more higher than single color ones. 3.Their application places are different; Full color outdoor rental LED screens have P6.9, P7.8, P10.4, P15.6, etc according to different application. They can be applied into various events like concert stages, exhibitions, celebrations, ceremonies, Olympics and sports games, fashion shows, etc. While single color LED screens have limited application because its visual effects is no better than full color ones. As an outdoor screen rental service provider, Glux advice you to use full color outdoor LED screens for your project. The price of LED screens is influenced by various aspects. Different LED screen supplier will provide you different price, it is all according to their situation. The following article will help to analyze some aspects that will influence the screen’s price difference. This will help us to calculate the cost for different indoor and outdoor rental LED display screens.
1.The LED chips takes large part to the screen’s material cost; LED chips will take 30% to 70% of the screen’s material cost. It is the mostly used components on a outdoor rental LED display screen. There are several LED chips brand in the market now, like CREE, Nichia, as well as other brands. These chips’ price difference will largely influence the screen’s price. Some LED screen rental service provides provide you a quotation with low price, then their screen may use low quality LED chips. 2.Screen’s structure and performance; Nowadays, there are carbon fiber cabinet material, aluminum material cabinet and metal material cabinet outdoor rental LED display screens in the market. In addition, the structure of different LED screen are also different, some are very thick and heavy, some are thin and light. In addition, the waterproof ability and other protection are also different. Some LED screen can only prevent light rain and water; some are able to sustain heavy rain and water washing it. That’s another aspect will influence the screen’s price. 3.Supporting facilities; The supporting facilities of outdoor rental LED display screens, like the electrical wires, controlling system, video signal processor, supporting elements are also a part in the quotation. 4.After-sales service and warranty; Most outdoor screen rental service providers will provide 1~2 years of after-sales warranty now. If you want to prolong the warranty period, the price will be higher, but it is good for you during using. Actually, there are many other aspects we need to consider about when calculate the screen’s price of outdoor rental LED display screens, such as the transportation ways and cost, tax rate. These aspects will also influence the screen’s price. Some people concerns about the visual effects when choosing different pixel LED screens. Today, we will take a P8 outdoor rental LED display screens and a P10 one as example, and comparing which one is better.
1.Compare them with same distance; As for P8 LED screens, there will be more LEDs than P10 LED screen in same area. Therefore, P8 screen has better visual effects than P10 one if we stand same distance away from them. The reason is the smaller the pixel is, the pixel density will be (there will be more LEDs in same area). Smaller pixel LED screen has higher definition. Different pixel outdoor rental LED display screens have different view distance range. The mostly used formula is: Best View distance = pixel pitch/(0.3 ~ 0.8) 2.Comparing with their cost; If we comparing from this aspect, there is no doubt that smaller pixel LED screens are more expensive. Because small pixel LED screen will use more LEDs, and the production and technology difficulty is higher. So the material and production cost of smaller pixel LED screens are higher than large pixel ones. 3.Which one is better? Most LED screen rental service provider will tell you that they are all very good, but just suitable for different application environment. For example, P8 LED screen’s view distance range is 10 to 26 meters, P10 LED screen’s view distance range is 12 to 30 meters. If you need 10 to 20 meters view distance LED screens, P8 is better; if you need 20 to 30 meters view distance LED screens, P10 is better. So, it is meaningless to say which one of them are better. They just suitable for different distance and environment. When choosing outdoor rental LED display screens, it is better to have a overall consideration about the practical situation of your event, you budget and other aspects together. To create better visual effects for your audio visual events, it better to ask your outdoor screen rental service provider to choose appropriate LED screen for you. During the packing and transportation process, outdoor rental LED display screens, as well as other LED screens will be placed into flight cases? Why will the LED screen rental service providers use flight case to pack the screens? Can we use other kind of case?
In the past, we transparent the LED screens with wooden or iron case. These kinds of case have some disadvantages like less maneuverable, inconvenient for loading and unloading, not environmental protective, etc. Today’s high quality LED screens have higher packing and transportation requests. Therefore, traditional case can not meet today’s demand. On this basis, higher level flight case was created. Most LED screen rental service providers are using this kind of case to packing and transporting their single color, full color indoor and outdoor rental LED display screens now. The features and advantages of flight case are as followings: 1.The surface material and color can be customized according to our request; 2.Traditional packing case needs mould during the production. Use flight case can save some mould cost, and the size can be customized according to our screen’s packing requirement; 3.There are partitions inside the flight case, these partitions are covered with vibration-proof material, better to protect our outdoor rental LED display screens; 4.LED flight case has wheels at its bottom, much easier for us to move, better maneuverable; With these advantages, outdoor rental LED display screens are well protected during the packing and transportation period. That’s why more and more outdoor screen rental service providers are using this kind of packing case now. With the development of outdoor displaying events, outdoor rental LED display screens are applied into these events more and more frequently. LED screen has various advantages like high brightness, energy saving, wonderful color, vivid picture and video displaying, large display area, long visual distance, etc. With its more and more wide application, the technical requirements are also higher now, especially the LED chips. As for this mostly used components on the screen, how will it influence the outdoor rental LED screen’s performance? The engineer from Glux Visual Effects Tech will explain this for you.
1. View angle. The view angle of LEDs will determine the view angle of the outdoor rental screens. Normally, the outdoor screens from other LED screen rental service providers are with 100-120 degree horizontal view angle and vertical view angle (some of the screen’s vertical view angle are event smaller). By using better quality LEDs and technological innovation, Glux’s outdoor rental LED display screens are with 140 degree both horizontally and vertically. 2. Brightness. The brightness of LEDs is important and determinate factors to the brightness of LED screens. The higher the brightness, the better to the LEDs working stability and energy saving. If the brightness of LEDs is good, then the screen’s brightness will also be high. 3. Failure rate. A whole outdoor rental LED display screen is made up of thousands and thousands of LEDs (with red, green and blue color on each LED), if one color in a LED chip or one LED chip failed, the visual effects of the whole LED screen will be influenced. Normally, the LED screen rental service provider will control the LEDs failure rate less than three over ten thousand from the assembling process until 72 hours aging test process during the production. 4. Size. The size of LED chip will influence the pixel pitch of outdoor rental LED display screens. Therefore different pixel pitch screens will use different size LEDs. For example, 5mm LED chips are mainly used for P16 or large pixel LED screens, 3mm LED chips mainly suitable for P10-P15 LED screens, 2525 and 3535 LEDs are mainly used for P6, P7, P8 LED screens. 5. Evenness. LED screen is made up by many pixels with red, green and blue LEDs, the brightness, wavelength evenness will determines the whole LED screen’s brightness evenness, white balance (color balance) evenness and chrominance evenness. Different outdoor screen rental service providers will ask their material supplier to provide different LEDs with different brightness and wavelength. That’s one reason why different supplier’s screens are with different quality. 6. Attenuation characteristics. After the outdoor rental LED display screens been used for a long time, their brightness may decrease and the color may not even. That’s because the LED’s brightness attenuated. The attenuation of LED’s brightness will decrease the screen’s brightness; if the attenuate rate of red, green and blue LEDs are not even, then the color of the whole LED screen will not even. High quality LEDs can control the attenuation rate. The attenuation characteristics of LEDs is related to the characteristics of its red, green and blue LED, the electric circuit, heat dissipation ability of the PCB and the application environment of the outdoor rental LED display screens will all influence it. 7. Lifespan. Theoretically, LEDs have 10,000 hours lifespan, larger than other components of outdoor rental LED display screens. So if the other components are with good quality, the electrical circuit is reasonable, the PCB heat dissipation are well, the production technology is exquisite, the LEDs will be the longest lifespan components on the LED screens. LEDs take 50%-70% of LED screens’ cost, so the quality of LEDs will largely determine the quality of the LED screens. Higher quality request is not only the future developing trend of LED screen industry, but also concerns to the future of all LED screen rental service providers. The visual effects of LED screens will also influence the effects of the audio visual events. All outdoor screen rental service providers should use higher quality LEDs when producing the screens; the outdoor rental LED display screen users should pay more strict attention to the quality of LEDs when choosing screens from different LED screen suppliers. |
