HD Led Video Wall Efficient Application

- May 20, 2020-

Under the vigorous promotion of manufacturers, today's HD led video wall has become a rising star in the field of large-screen display, and naturally has become one of the popular choices of many industry users. However, in view of the short rise of the HD led video wall industry and the limited scale of application, most industry users understand it from the manufacturer ’s propaganda, and in order to enhance their brand influence, manufacturers have developed a variety of concepts, which undoubtedly make the industry users aware more difficult. What factors should be paid attention to when selecting HD led video wall to ensure efficient application?


Dot pitch, size and resolution are closely related, product selection should pay attention to the application place


In the current small-pitch LED market, dot pitch, large size, and high resolution are the key points of the manufacturer's technology PK. In the traditional consciousness of the people, the three are important elements that determine the HD led video wall. Naturally, they must be selected. In actual operation, three factors will also affect each other-the specific dot spacing must be matched with the appropriate screen size to present the resolution.


Theoretically, in practical applications, P1.6 products should achieve a full HD resolution of 1920x1080, and the screen size should reach 144 inches. Even without a base, the length and width specifications are also 3.2 meters x 1.8 meters. If the user's application space is limited, the installation difficulty will be greatly increased, and the cost will naturally increase. Moreover, if the audience wants to get the best viewing experience, they must choose the best viewing distance. In actual operation, the user can calculate through a simple formula: visible distance = point spacing / 0.3 ~ 0.8.


That is to say, in the practical application of HD led video wall, it is not that the smaller the dot pitch and the higher the resolution, the better the actual application effect, but it is necessary to comprehensively consider factors such as screen size and application space. At present, for HD led video wall products, the smaller the dot pitch and the higher the resolution, the higher the price. If users do not fully consider their own application environment when purchasing products, it may cause a large price but not reach Dilemma of expected application effect.


Large-scale product selection must fully consider maintenance costs


Compared with other large-screen display products, a prominent advantage of the small-pitch LED display is "seamless and infinite splicing", which fully meets the large-size display needs of industry users. However, in practical applications, users in the industry should consider not only high procurement costs but also high maintenance costs when choosing large-size products.


Generally speaking, although the life of LED lamp beads can be as long as 100,000 hours, due to the high density and small pitch LED display is mainly for indoor applications, the thickness is required to be low, it is easy to cause difficulty in heat dissipation, and then cause local failure, In actual operation, the larger the size of the screen body, the more complicated the maintenance process, and the maintenance cost will naturally increase accordingly. Therefore, for large-size products, users must do their best. It is not that the larger the size, the higher the application efficiency.


Signal transmission equipment can not be ignored, the signal compatibility of HD led video wall is very important


In the application of small-pitch LEDs to the room, the first problem to be solved i small pitch LED screen s the access of multiple signals and complex signals. Different from outdoor applications, indoor signal access has diverse requirements, large numbers, scattered locations, multi-signal display on the same screen, centralized management, etc. In actual operation, for HD led video wall to be efficiently applied, signal transmission equipment must not be underestimated. .


It is worth noting that in today's LED display market, not all HD led video wall can meet the above requirements. For example, in the front-end monitoring system of security monitoring applications, generally include D1, H. 264, 720P, 1080I, 1080P and other formats of video signals, some HD led video wall products cannot fully support the video signals of the above formats. For users in the industry, when buying products, avoid paying one-sided attention to the resolution of the product, and fully consider whether the existing signal equipment supports the corresponding video signal, otherwise it is difficult to achieve the expected application.


Conclusion:


Based on the huge market development potential, more and more companies are beginning to pour into the HD led video wall market. This rapidly enlarges the market size, but also makes the products on the market uneven, coupled with the lack of unified judgment standards, users are inevitable Enticed by the marketing trend of the manufacturers, in order to avoid unnecessary investment waste and ensure application effects, users must consider their own application needs comprehensively, adhering to the principle of on-demand selection. At the same time, it is worth noting that for the efficient application of HD led video wall, in addition to their own performance, they must be matched with appropriate solutions. Obviously, not all practitioners have the corresponding capabilities, and users are buying products. It is necessary to have a certain brand awareness. After all, large companies have outstanding advantages in product types, pre-sales guidance, and after-sales service capabilities.
