Make the display better - explain the domestic LED display control system

LED display control system is divided into synchronous and asynchronous. Synchronous control system is almost developed along with the development of LED display. The technology is mature and the market acceptance is high. The asynchronous control system develops late, the operation is flexible, and it also has its own. The world of application. In the future, whether it is a synchronous or asynchronous control system, it is necessary to continuously improve the performance and help the LED display products to a higher level.

As an important segment of the LED display industry chain, it is necessary to understand the technical level and market trends of the control system, and it is also an important task to promote the development of the industry. In order to comprehensively and centrally understand what the current control system manufacturers think and do, this issue specially plans "LED display control system special", which is expected to get the industry's response.

Generally speaking, a good LED display requires not only high-quality LEDs, good driver ICs, and excellent material accessories, but also one of the most core components is the control system. Choosing a suitable control system can help display products to display more perfect images and broadcast videos.

LED Display Control System (LED Display Control System), also known as LED display controller, LED display control card, can be divided into asynchronous control system and synchronous control system. The LED display control system mainly focuses on the business needs of customers, and adopts centralized control and unified management to combine various media files such as pictures, slides, animations, audio, video and scrolling subtitles into multimedia programs and transmit them to digital media through the network. The controller then performs orderly playback and control on the corresponding display device according to the control rules by the digital media controller, and inserts various instant information such as news, pictures, emergency notifications, etc. at any time, and transmits the latest information in the first time. To the audience.

The development of control systems has evolved with LED displays. In the early days when the single- and two-color LED display was booming, the synchronous control system was already in its infancy. After 2000, the LED display synchronous control system has begun to occupy the display field. After more than 10 years of development, most of the LED displays on the market currently use synchronous control systems. Relatively speaking, the asynchronous control system started late and experienced a long incubation period. Until the current full-color LED display became popular, the asynchronous control system gradually revealed its sharpness.

Technically speaking, the synchronous control system is relatively mature, and the market share in the conventional display field is much higher than that of the asynchronous control system. The asynchronous control system is slightly lacking in processing performance and stability, and has been continuously improved and improved in recent years. . With the quality requirements of the LED display and the improvement of the broadcast effect, the LED display control system has also made considerable progress. In the synchronous control system, the technical indicators such as gray level, signal processing and refresh rate have been greatly improved, and there has been no small improvement in reliability. For example, the flexibility of the Lingyu rain control system is greatly improved, and it can better adapt to various needs. The Nova control system has many improvements in grayscale and refresh rate to accommodate high-density small-pitch screens. The cluster control system solution has also made great breakthroughs, and has been maturely used in the national networked broadcasting project; the Mosier control system has improved in cost performance. New technologies have also been introduced on the basis of the traditional serial structure, such as Carlet's no-send card network direct writing technology, and the elephant-oriented broadcast grid structure technology. As for the asynchronous control system, the asynchronous control system manufacturers such as Lingxin also fully improved the corresponding performance, and even better than the synchronous control system in terms of computer operation, flexibility, convenience and even wireless release, especially suitable for small and medium area LED display. Screen project.

Due to the long-term use of LED display, the loss of brightness and chromaticity and the difference gradually appear, which affects the display playback function. In order to ensure the consistent playback effect of the LED display, the control system manufacturers are also working hard. For the related work of brightness correction and chromaticity correction, or jointly developed by the corresponding professional calibration manufacturers, such as Nova is more focused on point-by-point correction technology. Compared with the synchronous control system, the asynchronous control system still has gaps in the application of the color correction system and performance indexes such as high refresh rate and high brightness, and needs to be continuously improved and improved in the future.

At present, China's LED display control system manufacturers are difficult to count, and their competition is much lower than that of LED display manufacturers. However, due to their narrow market share and relatively limited technology, it is determined to be LED display. A specific segment of the industry chain.

As the LED display industry continues to develop new markets, displays in various subdivisions place higher demands on control systems. For example, high-density and small-pitch LED display is an emerging market with strong development momentum in recent years. The reduction of dot pitch has challenged various devices such as driver ICs and control systems. In the future, synchronous and asynchronous control system manufacturers also need Further improve performance and help the perfect display of LED display.

In a certain period of time, the synchronous system and the asynchronous system will continue to exist each other. The asynchronous market space is indispensable, although it is small. Just as the emergence of IPad is not a substitute for laptops, it is also a new highlight on the market that cannot be ignored. In the future, synchronous control systems and asynchronous control systems may be combined to some extent, and the two will be united with each other to complement each other, and even new products with both optimal characteristics will emerge. This is just like the fact that Ipad is a product between mobile phones and computers. It is a combination of the advantages between the two, and it is also a product of the laws governing the development of things. Currently, LED synchronous control system manufacturers are also actively integrating with asynchronous systems, and Nova Technology is currently an active practitioner of this trend.

In addition, with the development of computer network technology, LED display screens are used more and more in the network environment. In the information display system composed of multimedia and multiple display devices, intelligent network control and networked control multi-screen technology are adopted. It is also applied in practice.
