The LED screen is mainly composed of arrays of light-emitting diodes. It adopts a low-voltage scan driver; which consumes less power, saves energy and environmentally friendly, and it can extend its service life as well. Compared with LCD displays, LED displays have obvious advantages in terms of brightness, power consumption, viewing angle and refresh rate. The reaction speed of a single element of LED display is hundreds of times higher than that of other displays. Even in a strong light outdoor environment, it does not affect the viewing effect, and it can adapt to various high and low different temperatures. The higher refresh rate allows LEDs to have better performance in video, and can also provide a wide viewing angle of up to 170°.
The current front-end acquisition equipment on the market generally includes D1, 720P, 1080P and other formats of video signals, so as a back-end signal output product, it has strict requirements on various resolutions. The LED screen can not only display various text, numbers, colored images and animation information, but also it could play colored video signals such as TV, video, VCD, DVD, etc.; and multiple display screens could also be adopted to do online broadcasting.
What are the requirements for large LED-screen display systems in the security field? As we all know, the signals that need to be displayed in the control room are rich and more complicated. There are more digital signals than video signals, which imposes harsh requirements on display products and technologies. For example, high-resolution refined display, high-gray restoration display under low brightness, high refresh rate, high consistency and uniformity, low noise, heat dissipation, etc.; and even the comfort level of long-term continuous viewing; these are some of the high requirements.
As the high-end market at the top of the pyramid of the LED display market, the control and monitor room market not only just require the led display products, but also has stringent requirements in the overall application, requiring the LED display manufacturers to provide customization for different types of specifications as to meet the requirements as in scenarios as in control rooms, command centers, and dispatch and monitoring centers etc.; to presented the end users with a complete set of systems and a complete and appropriate integrated solutions.
Sansi has been the manufacturer and solution provider for years to provide customized solutions to our customers in the regard of scenarios as such. The size and specifications of the LED screens are specifically customizable according to our user’s requirements, ranging from less than one square meter to hundreds of square meters, and can also be designed specifically case by case.
