How does the Outdoor Hanging LED Display cope with the bad outdoor environment

The  outdoor hanging LED display  , used as an outdoor advertising device, is much more demanding for the environment than a typical display.  Outdoor hanging LED display in the process of use, due to the different environment, it is often affected by bad weather such as high temperature, typhoon, heavy rain, lightning, etc. To make the display safe in bad weather, we must take precautions to ensure its safety. The following is an introduction to  the precautions for outdoor LED displays in inclement weather. First, prevent high temperature. In production, ensure that the display circuit board is in good condition. When designing the outer casing, choose a hollow design to help dissipate heat. In the installation, according to the situation of the device, stick to display the situation drafty in good condition, and add heat dissipation equipment to the display when needed, such as installing an air conditioner or a fan to help the display to dissipate heat. Second, p...

Reasons for hindering the application of the free glass 3D LED display

At present, VR/AR and free glass 3D are the development hotspots in the current display field, but there are not many actual application projects. The problem of technical defects is only part of the constraint to its development.  It is understood that most of the products of  free glass 3D display , which are being developed by LED display manufacturers, have the defects of Angle limitation. Many companies are in the research, development, production of free glass 3D displays, will show a lot of problems in the process, and the key technical points is the design of the "multiple viewpoints, which make the audience can see the eddect of 3D regardless of where they stand. Now, it's easy to do one, two, four, eight viewpoints, but it's harder to do dozens. However, some enterprises have proposed active 3D technology, which is expected to solve the problem of viewpoint. Secondly, it is the restrictions on the use environment and size of free glass 3D. At present, there are m...

The development of free glass 3D led display technology is difficult

From 2014 to 2015, when the development of the  free glass 3D led display was hot, the strength of the R&D team was enormous. Liad, Alto Electronics, Chau Ming, Sansi, Zip Optoelectronics, Easystar, Mai Rui Optoelectronics and other companies are in the ranks of R & D. From the scale and strength of the company, it can be seen that LED display companies invest a lot in R&D of the free glass 3D technology, but even so, the free glass 3D technology can not compare with the small pitch, thus forming a mature market. It is understood that most of the  free glass 3D technologies are in the research and development stage, and its research and development are divided into two directions, one is the development of hardware devices, and the other is the development of display content processing. In the past few years,  free glass 3D led display  screens have been launched. In 2015, 3D technology was rushed to be developed by major LED display manufacturers. Howe...

Be Careful of Storage Performance Track

图片
Excellent performance is an everlasting pursuit for storage system vendors. Vendors use different performance parameters to promote product performance, such as 100% cache hit ratio (maximum IOPS), 256 KB I/O bandwidth, and 100% write latency. All vendors want you to believe that they can provide the highest performance and can easily handle business pressure during peak hours. You may want to know how to identify all-flash arrays that truly have high performance from amongst a huge number of potentially misleading promotions. Track 1: 100% cache hit ratio When promoting storage performance, many vendors often boast they can achieve “100% cache hit”. This means that all data is stored in memory, instead of being stored permanently. A criterion to determine whether IT architecture is high performance is to check whether it stores the most frequently accessed data in the location that has the fastest response times. This essentially means that it is almost impossible to have a 1...

LED outdoor electronic display has now become a beautiful landscape line in the city. However, the recent bad weather environment also causes various problems in the  outdoor electronic display . Spontaneous combustion, leakage of quality and safety accidents are common. So, what details should be noticed for purchasing outdoor electronic display?  Compared with the Led display panel for indoor applications, LED outdoor electronic display has a higher resolution to meet the effects of various remote or high ambient light states. The traditional LCD display resolution can only reach 1024 x 768. According to the actual test data, the demand for the resolution of the display device is at least 1920 x 1200 for outdoor applications, so that it can appear normally under the influence of sunlight. For smart advertising player, "resolution" will not become a big problem of its application popularity. However, the outdoor environment is changeable. In order to allow the outdoor smart ...

Led Information Display to Create The Perfect Stage

1.A stage based on the stage frame of  led information display s as the main body and the position of the light is left around each unit screen. Such a stage is more common, and the stage structure is built in a deep manner.  The screen is suspended from the stage frame, and the lighting effect is hung between the screens.  It's the depth and patchwork of the screen that leads the stage to the distance, which makes the depth of field of the whole picture longer, resulting in a strong perspective effect. With so much room left for the lights to hang and play, the whole stage also has a good atmosphere and dynamic and also expresses the theme of this evening party. However, the stage structure will appear to be relatively simple and not vivid.  2.The big screen is all the stage design, the big screen is designed as the background, the side curtain, everything in the scene, such as space and time, is done by the big screen, and the actor does a non-physical perfo...
