Arc-shaped LED screen, LED soft screen, LED bus screen and other LED display information



A. main functions of the box:




   a.1 fixation: for display components such as internal fixation module/unit board and power supply, all components must be fixed inside the box to facilitate the connection of the whole display, and external fixation of frame structure or steel structure.





   b.1 protective effect: the electronic components inside can be protected from the interference of the external environment, which has a good protective effect.






B. Box classification:




   a. Material classification of the box body: the general box body is made of iron, and the high-end box body can be made of aluminum alloy, stainless steel, carbon fiber, magnesium alloy and nano-polymer material.





    b, the use of the box classification: the main classification is related to the use of the environment, from the waterproof performance is divided into waterproof box, simple box;From the point of installation, maintenance and display performance, it can be divided into forward turning box body, double-sided box body, arc box body and so on.

Arc LED screen


C, the introduction of the main box




    a. Introduction of curved led display case




Arc-shaped led box is a special led display box designed for various arc-shaped screens.Arc-shaped boxes are classified into two types: outer arc and inner arc. In general, arc-shaped boxes are made of arc-shaped structure, while modules and unit plates are ordinary materials. In addition, various arc-shaped display screens are made of arc-shaped steel structure design.





     b. Front flip led display case and front maintenance display features




In special occasions, the front flip led display box must be used to make the front maintenance display screen and the front door opening display screen. Its main features are: the whole box is made by connecting the front and rear halves above and opening them below.




Box structure: the whole box is like a hinge which is opened from the bottom to the top. The components inside the box can be repaired and maintained after the box is opened below. After the screen is installed or repaired, the outer side can be lowered and the buttons are locked.




Suitable for outdoor led display, installation with a row of boxes and no maintenance space at the back.




Advantages and disadvantages: the advantages are convenient for the maintenance and repair of led screen body without maintenance space;The disadvantage is that the cabinet has a high cost. When making the led display screen, there are several times more power lines and wiring between the two cabinets than the ordinary cabinet, which affects the efficiency of communication and power supply and increases the production cost.





     c. Double-sided led display box structure




The double-sided led display box, also known as led double-sided box, is mainly used in the electronic display which needs to be displayed on both sides.




Box structure: the box structure of two-side display screen is equivalent to two front maintenance screens connected back-to-back, and the double-side box is also a special front-turning structure box, the middle part is a fixed structure, both sides are connected to the upper part of the middle, and one side of the box that needs to be repaired or maintained can be opened up when maintaining.




Features: a. The screen area cannot be too large, generally one box and one display screen; b Mainly adopt hoisting method for installation;c, the two sides of the display screen can share a led control card, the control card USES the partition control card, the general two sides of the area is the same, the display content is the same, just need to put the software inside the content into the same two parts.

D. Development trend of LED display box




  In recent years, small spacing technology with its more high-quality 3 d display effect and can better fusion and interaction between the VR/AR, emerging technologies to express ideas actively into the advantages of outdoor LED display field, fixation and open up a large number of emerging markets, such as gas station signs, electronic YueBaoLan, bus stop segments cannot use original small spacing, now can be widely used.




   

  But small spacing for fast development of LED display in the field of outdoor solid loading, to construction display industry bring great change and ascension at the same time, we also found that some of the resulting change: for example, mainly iron box module on the market due to the heavy weight, such as poor precision and insufficient strength weakness has failed to keep pace with the LED display screen the development needs of small spacing, and some new module material increasingly caught the attention of the market.





   And among them will tell the market voice most at present is "die casting aluminium".




After several years of development, the die-cast aluminum box is lighter and lighter in weight, more and more reasonable in structure and higher in precision, which can basically achieve seamless splicing.The latest die-cast aluminum display screen is not only a simple upgrade of the traditional display box, but also a comprehensive optimization and update in terms of structure and performance. It is a compact indoor rental display screen made by patent, with high splicing precision, and extremely convenient for disassembly and maintenance.





   In addition to die-cast aluminum, there are a lot of new materials also began to get attention in the industry, such as: carbon fiber, magnesium alloy, profile, nano-polymer materials as hot LED display box replacement materials, they have their own advantages:





  Carbon fiber LED display box:




The design is ultra-thin, light in weight, good in strength and tensile strength, with a weight of 1.5 tons and a weight of only 9.4kg per square meter.And the use of a fully modular design, more convenient maintenance, 45 degrees of right-angle edge can achieve 90 degrees screen body assembly installation, while providing non-transparent backplane, suitable for stadiums, outdoor advertising lamp field large area installation.





  Magnesium alloy LED display box:




Low density (about 1.8g/cm3 magnesium alloy), high specific strength, large specific elastic modulus, good heat dissipation, good shock absorption, better impact load bearing capacity than aluminum alloy, good corrosion resistance to organic and alkali.Magnesium alloy used as LED display box has the advantages of high cost performance, easy installation and excellent heat dissipation.





  Nanometer polymer LED display box:




It is shockproof and shockproof, and its weight is much lighter than the conventional box, with a single box weighing only 4.5kg and 5.1kg.Simple loading and unloading, light handling, and low truss cost, low transportation costs.




Their biggest common advantage is that they are light, thin and easy to install.This is a future development trend, and it is obvious that the "iron box" is no longer adapted to this trend, the future is destined to be replaced by better new materials.However, it will take a long and continuous process for it to be removed from the market. Therefore, it still has the advantages of low cost and short production cycle (which is exactly what new materials need to break through at present) and will not be abandoned by the market completely.










   With the outdoor fixed LED display increasingly favored by customers, customers' demand for products has also changed, and they tend to choose products that can meet their more diversified and personalized needs.Just like the LED display box replacement material research and development, although there have been so many new materials, but there are still many people in the industry continue to explore other new box materials with higher reliability and higher cost performance.Screen enterprises must pay attention to and seize new development opportunities in real time -- actively research and develop new products, in order to make continuous progress and constantly open up new markets.
