LED display peripheral equipment plays an important role in the transformation and upgrading of LED
With the maturity of China's LED display technology, the development of LED display screens is growing year by year. The LED display market is also diversified. The emergence of new products such as special-shaped screens, light bar screens, transparent screens, and small pitches is undoubtedly not a technological innovation. The application of the above innovative technologies has also put forward higher requirements for LED display peripheral equipment manufacturers. Therefore, peripheral equipment plays an important and indispensable role in promoting the development of the entire LED display industry. It not only affects the overall display effect of LED display products, but also the application and generation of new technologies of peripheral devices have also brought about a transformative impact on the diversified development of LED displays.
LED display peripheral equipment plays an important role in the transformation and upgrading of LED
Nowadays, enterprises as LED display peripherals are not only staying in line with the current LED display development needs, but some enterprises have begun to produce pre-existing peripheral equipment products and technologies by increasing product research and development. A new breakthrough has been tapped for the LED display market. Thereby affecting and driving the development of the entire industrial chain of LED displays. Therefore, the technical research and development of LED display peripheral equipment has also become the focus of the industry. The LED display peripheral equipment we usually call is mainly composed of four parts: control card, video processor, power supply and driver IC.
First, the important core part - control card: Among them, the control system is a system that determines what content of LED large screen to play, equivalent to the human brain. It is very important to choose a control system. Generally, we should choose a control system that is convenient to play, flexible in playback, and easy to learn. Some have a large number of points, support for large resolution display; some have good scalability, suitable for LED shaped screen. For example, the LED spherical screen requires special requirements for the control system and the video source to be played, in order to have a perfect display effect.
It must be mentioned that Nova Technology, the industry leader in control systems, is the world's most competitive LED display solution provider. With LED display synchronization control system, asynchronous control system, point-by-point correction system, video control system, single and dual color system, cluster broadcast control system and other product lines, these product lines rely on each other to form a complete ecosystem. In addition, the Carlet i6 receiver card can be easily integrated into the adapter board or display unit board using the DDR2 SODIMM interface, which makes the display module highly integrated, which greatly facilitates the design of the display unit board and structure.
Second, high-definition image quality presentation - video processor: In the high-definition LED display era, the video processor not only carries a lot of work such as image processing and analysis, codec compression, but also embedded a large number of intelligent analysis algorithms for massive HD data. Analysis, the burden plays a more important role. The core of this technology is not only reflected in the sharpening of the edges of the image, but also includes the processing of color restoration and image scaling. The quality of this indicator of the video processor directly reflects the image clarity displayed on the LED display.
With the civilianization of high-resolution products, 4K has become the norm. The surge in signal sources and simple multi-picture output may solve the problem of the small-pitch era, but in the post-small-pitch era, the solution in the screen 2.0 era is obviously powerless. Based on a larger and more complex signal source, the number of monitors has also increased dramatically. To perform real-time preview and monitoring of LED displays, traditional solutions often require the use of multiple displays. However, Wei's video has the industry's first professional LED display 4K2K processor, which can set the output resolution for different physical resolutions of different LED displays, so that it can zoom in and out, and capture the input signal in full screen. .
Third, the source of LED display energy - power: only ensure the reliability of each link, in order to make the LED display achieve a perfect effect in the final presentation. However, power supplies are also a vital part of the LED display peripherals. All components on the display use DC 5V. A dedicated power supply for display of various powers, the most used display power supply is 5V40A (200W).
The industry's leading level of giant energy Albert, the production of ultra-thin series of power products using a high-purity aluminum casing, 1mm higher than the market power shell thickness, the material is more solid, better heat dissipation. The ultra-thin series of power supplies have a wider range of applications, with both ends connected to the output or one end of the output, which saves engineering costs. Product quality is also more secure, the price is basically the same as the traditional power supply with the same parameters.
Fourth, low-light high-gray true high-brush-drive IC: In the performance indicators of LED display, refresh rate and gray level and image expressive power is one of the most important indicators. This requires high consistency of current between the LED display driver IC channels, high-speed communication interface rate, and constant current response speed. In the past, the refresh rate, grayscale and utilization rate are a trade-off relationship. To ensure that one or two of the indicators can be superior, it is necessary to sacrifice the remaining one or two indicators.
However, with the small spacing gradually becoming a hot spot in the development of the domestic LED display industry, the status of wanting to lead the trend also requires the active cooperation of the “behind-the-scenes” supporting manufacturers, but also brings a series of challenges. Today's driver ICs have successfully achieved "low-bright, high-gray, high-brightness (high shooting refresh rate)", and perfectly solved the "seven problems" caused by low-light and high-ash, which can effectively meet the small pitch. The need to display. Ming Microelectronics has been committed to the deep research of driving ICs. Among them, the non-isolated high-voltage linear constant current LED driving power technology introduced by them has become a new hot spot of LED light source driving. The non-isolated high-voltage linear constant current driving power supply has no transformer and inductance. And electrolytic capacitors can cost less than isolated drive power.
In summary, as a manufacturing power in China, many products are going abroad in the process of globalization, and LED displays are also the same, but the LED display products are going globally, and the market demand for the display of LED display projects. The higher. If LED display technology is the leading technology and cannot match the display accessory products corresponding to high-end products, it will not be sustainable. China's LED display industry will not be able to adapt to the needs of foreign high-end markets.
Although China's LED display peripherals account for a small proportion of the entire LED industry chain, it has an irreplaceable role in promoting the transformation and upgrading of the entire LED display products. LED peripheral equipment can only lead the entire industry forward by innovating to form a complete industrial chain.
