Looking back at the development history of LED outdoor display, we can clearly see three main lines: the first line is the development of high-definition display effect; the second line is the thin and light structure of LED display; the third line is LED display The screen area is getting bigger and bigger. The next two lines are related to the topic of LED curtain products that we are going to discuss today.
What is LED screen products?
The LED screen products are LED display products with strip shape, hollowed out, light transmission, no influence on ventilation and lighting, and have a completely different structure from the traditional LED cabinet screen. We can look at the product promotion video of Daktronics to learn more about LED screen products.
LED screen products are also known in the market as light bar screens or grid screens, grid screens, etc., which were first used for stage rental. In recent years, they have been widely used in large-area display installation projects of building curtain walls. It is ideal for building super-large outdoor displays and is the first choice for creating landmark dynamic displays.
Up to now, the display pitch of such products has grown from the earlier 50mm to the current minimum of 7.81mm, and in some places requiring high transparency and low load, there are already conditions to replace conventional outdoor cabinet products.
The first is high cost
The use of a large number of steel structures has created additional costs for customers in terms of procurement, transportation, and manpower; cooling equipment such as air conditioners has not only increased procurement costs, but also become a major consumer of electricity. Customers buy LED displays, but they have to pay for steel structures and air conditioners, which is unreasonable.
The second is the difficulty of approval
The use of a large number of steel structures, together with the sheet metal body of the screen itself, will make a considerable part of the building unattainable, making it difficult to pass the approval.
Again limited
First, because of the load-bearing and shaded lighting, the LED display using the traditional cabinet is difficult to do in a large area installation in some buildings with glass curtain walls.
Second, because the windproof design is not enough, the LED display using the traditional cabinet has a great safety hazard installed on the roof.
Finally, it is difficult to maintain. First of all, the traditional LED display is limited by the design method, and the Power Supply, signal line and other accessories are easily damaged. At the same time, these displays adopt the post-maintenance mode, and the maintenance is inconvenient after the failure. Higher failure rates are not easy to maintain, which affects the customer's advertising revenue.
In the face of the above problems, LED screen products have a good response with their own characteristics.
Light and thin to solve the problem of limited installation
Due to the air-saving and steel-saving structure, the LED screen display products greatly reduce the difficulty of the screen on the building load and installation; the ventilation does not block the light, which not only achieves good space behind the screen, but also achieves high frontal viewing. Contrast.
Display and control separation structure can solve heat dissipation and improve product life
According to statistics, 60% of outdoor LED display failures are caused by heat dissipation. LED screen display products have abandoned the extra sealed box, disperse the product, perform control separation and transparent design, increase the heat dissipation area, and achieve the heat dissipation requirement through natural ventilation, thus eliminating the heat dissipation of the air conditioner. equipment. In addition, by adopting the patented design of the viewing angle structure under the light bar, the LED light energy is utilized to the utmost extent, and the special sunlight is used to prevent the sunlight from heating the display part, further ensuring the temperature of the product. Rise within the standard range.
Reduce operating costs and increase business value
Because the LED screen has a big difference in manufacturing process and control technology from the traditional display, its production cost is slightly higher than the traditional display, but it should be noted that the total operating cost is much lower.
First of all, in low energy consumption, due to the efficient self-heating design, no additional auxiliary cooling equipment is needed, and the energy saving of the conventional cabinet type LED display is more than 60%.
Secondly, the maintenance is convenient. On the basis of the display and control separation, the display part adopts the modular design of the light bar, and the light bar can be easily disassembled and maintained separately, and the large screen will not be stopped for a long time due to the maintenance.
In addition, LED screen products also have a strong styling ability, can fully fit the shape of the building, create a large display landscape, and enhance the commercial value of the building. We can experience the modeling capabilities of such products through the video of Jin Huaguang's exhibition.
Conclusion:
In summary, the emergence of outdoor LED screen display products has provided new product choices for the LED media market. With the efforts of a number of manufacturing companies such as Jinhuaguang, Anderson, Witham, and Rose Technology, the cost of curtain products will decline rapidly and the process will be further improved. When the LED screen products face the traditional LED display, showing stronger price competitiveness and clearer display effect, it will usher in more development space.
