Outdoor fixed led screen starts new vision for outdoor media

Once upon a time, outdoor fixed LED screen large screen advertising became the "Darling" of urban advertising because of its large and beautiful color characteristics. From Central Hong Kong to New York Times Square, all of them appeared. However, nowadays, due to its large area and the limitation of the advertising department on the brightness of the outdoor fixed LED display, the market of the large-screen display is limited. The spacing of P10 makes it impossible for it to become small and delicate, so the application scope is limited in a fixed circle.

In recent years, a number of outdoor fixed LED billboard screen enterprises have entered the outdoor small space research and development. From this year's perspective, Intellex pioneered P4 light source for outdoor high-definition surface mount; Lehman photoelectricity launched p3.9 outdoor fixed led sign high-definition LED screen with the world's smallest point spacing; Shanghai Sansi launched P4 outdoor small spacing Surface Mount LED screen product with the world's smallest spacing; Alto electronics released 5 new high-end LED display products at the European professional audio-visual integrated equipment and technology exhibition, including one with 3.0mm point spacing outdoor Ultra-high density LED display system. These LED screen enterprises have joined in the ranks of outdoor small spacing why they are "lured"? Next, the editor of this magazine will make some brief analysis.

Outdoor small distance led for closer viewing distance

Nowadays, the conventional LED display screen appearing in the market is usually the distance between P10 and P8. Such a distance makes the display screen, which is usually suitable for long-distance viewing, have a clear sense. In the case of short-distance viewing, you will see a clear boundary, which makes the image quality of short-distance screen "grain sense" obvious. Therefore, these conventional outdoor LED advertising screens are always in place In a position of "high above". However, the appearance of outdoor small space LED screen makes up for this shortage.

As the name implies, the outdoor small space LED display screen has a small space between the smallest pixels of its display screen. It will change from the mainstream P10 and P8 to P5 or even P4. With the reduction of the spacing, the screen will also be delicate, even in the case of close viewing, it will not be "invisible". Therefore, the appearance of outdoor small space LED display will be able to close the distance between the display and the viewer.

With the closer distance, the distance between the LED display and the audience is also closer. The audience can watch closely, which strengthens the communication effect of the media. In addition, with the emergence of small spacing, the screen of LED display screen can be smaller, so the limited range of its installation point will be smaller. During installation, it is not necessary to find a large area for installation, which also saves space. The screen is small, and one or even several LED advertising screens can be installed on one wall everywhere, so these LED screens can form an advertising network by combining.

With the progress of technology, it can be imagined that the LED display will appear in the streets like a large screen TV in the future, which will be very spectacular.

Difficulty in technology and price promotion

Although the outdoor small spacing LED display has begun to develop, but want to promote, there are certain difficulties for the technology of upstream and downstream led enterprises.

For the upstream manufacturers, due to the high contrast, clear and smooth characteristics of the lamp beads to meet the market demand of the downstream customers of the LED industry, the lamp beads suitable for outdoor small spacing LED display screen are very popular with the downstream customers of the LED industry, but it is not easy to make such suitable for outdoor use. Wang Aimin, director of intellech Optoelectronic Technology Co., Ltd., said: many enterprises can do well in waterproofing of outdoor small spacing products, but it is difficult to choose materials for outdoor surface stickers.

The brightness of the LED display is low, and the water-proof, moisture-proof and UV proof functional indicators can not meet the requirements of outdoor environment. For a long time, the outdoor full-color display is the world of direct plug-in LED devices. However, in order to make a good outdoor LED screen with small spacing, it is necessary to select surface mounted LED devices.

From the above we can see that the selection of outdoor surface materials is a major technical problem for the promotion of outdoor small spacing LED display. How to choose suitable surface materials to meet the needs of outdoor small spacing display screen, which needs continuous research. As the first outdoor surface mount P4 light source, how do they solve this problem?

Director Wang Aimin explained that for the downstream manufacturers of outdoor small space LED display screen, there are two main technical difficulties: signal transmission and safety protection.

In response to these two problems, relevant personnel of Shanghai Sansi Technology Development Co., Ltd. said: "first, single line transmission and self-scanning control technology. For example, Sansa's original single line transmission -- no flat cable -- signal distribution technology has thrown off the traditional signal connector, thus completely solving the problem of poor signal transmission caused by the loose connector. The interior of the case is clean and fresh, the layout and connection of the signal power supply are clear at a glance, ensuring the stability and reliability of the image display. At the same time, the self-scanning in high-density display bid farewell to the long-distance transmission of parallel signals improved the signal strength, enhanced the reliability of data supply, increased the functional proportion of the display panel in the outdoor fixed LED screen display control system, and weakened the intermediate signal conversion link.
