Outdoor LED display sales are the leading LED display, accounting for 80% of the total sales.Visible outdoor LED screen in the use of a very broad.What is the difference between outdoor LED screens and other LED screens?Below, we will introduce to you a few outdoor LED screen technology points

1. Definition: determine the required area of the screen body according to the optimal viewing distance point, and the optimal distance of the definition "40,000 pixels /m2" is 5-50 meters;Adopt the most advanced 16-bit data interface, further improve the clarity of the picture.

2. Brightness: the screen body brightness design is above 2500cd/m2, which can not only ensure the vivid color and clear image of P5 indoor full-color screen in normal use, but also ensure that LED screen has enough brightness and bright and clear video image when the lamp tube attenuation exceeds 30%.Refresh rate: the service life of the service life of the service life of the service life of the service life of the service life of the service life of the service life of the service life of the service life of the service life of the service life of the service life of the service life of the service life of the service life of the service life of the service life of the service life of the service life of the service life of the service life of the service life of the service life of the service life of the service life of the service life of the service life of the service life of the service life of the service life of the service life of the service life.Power supply and signal transmission mode: because of the importance of full-color LED display screen, the power supply and signal transmission shall be specially processed technically, using high-quality military-grade connector design.Furthermore, various faults caused by pulling force are controlled at the connector.

3. Control mode: select the self-designed control system, conduct 240-hour uninterrupted power on aging screening, and then select the highly reliable control system.In addition, dual redundant hot backup is adopted in the control mode. In case of any problem, it will be connected by another signal line immediately and continue to work normally with smooth connection.

4. Raw materials: all raw materials of LED display screen are brand name high-quality products, and the most important LED light is high-quality LED light;

5. Three-level product aging process: firstly, the module produced by the automated assembly line is electrified for 24 hours, and then the single box is electrified for 48 hours. Finally, the display screen of the finished product is electrified for 72 hours continuously.

6. Product quality control: all products are manufactured in strict accordance with iso9001-2000 quality certification system documents.(see quality certification certificate), will be strictly in accordance with the waterproof grade IP65 test, to achieve complete waterproof effect.LED screen installation and debugging: strictly follow the design scheme for LED screen installation and debugging, and the installation level is above grade C (the highest level of LED screen installation).

7. Leading system software (ready for screen application) : the operating system adopts Windows XP and supports the latest products of Windows series provided by Microsoft.All the applications are Windows operating platform and friendly interface.Playback software has rich clock function, it can display the current date, the current time, and the computer time synchronization of the display clock can be analog clock, can also be a digital clock.The software adopts advanced threading technology, which can play text, animation, clock, photo, audio and so on in multiple threads when playing the software.

8. Perfect system function design (ready for screen application) : this system can meet the requirements of assembly, performance, TV broadcast and advertisement broadcast.The LED display system of this project has multimedia, multi-channel, real-time transmission of high-speed communication data and video interface. It can easily introduce various forms of information sources into the computer network system to achieve unified control of various audio and video input.The detailed functions are as follows:

9. Video playback function can display true color dynamic video images;High fidelity retransmission of closed-circuit television, satellite television programs;Multiple video signal input and output interfaces: compound video, Y/C video (S_Video), YpbPr, VGA(RGBHV), DVI, HDMI, SDI(HDSDI);Can play high fidelity video recorder, disc player (VCD, DVD, LD) and other video programs;With video screen superposition text, animation and static pictures and other functions;Through the editing device, real-time editing and playing functions such as panorama, close-up, slow motion and special effects can be realized.Brightness, contrast, saturation and chromaticity can be adjusted by software with a range of 256 levels.It has the function of image freezing;Video +Video, Video and VGA display modes;With horizontal/vertical position compensation function;Display synchronization function.

10, computer graphics information playback function can display all kinds of computer information, text, graphics, pictures and second, three-dimensional animation;Rich play mode, display scrolling information, notification, slogan, etc., storage capacity of data information.The display body can open multiple Windows, display calendar, clock, insert single line flow text.There are a variety of Chinese fonts and fonts to choose from, but also can input English, Spanish, French, German, Greek, Japanese, Latin and Russian and many other foreign languages.Broadcast system with multimedia software, flexible input and broadcast of a variety of information.There are more than 20 broadcasting modes, including left and right scrolling, up and down scrolling, right and left pushing, up and down pushing, diagonal pushing, diffusion, fan type, rotation, scaling and so on.Display network data information through network connection.Equipped with a network interface, computer networking, sharing network resources, with a standard audio signal output interface to achieve audio and video synchronization.

As can be seen from these, outdoor LED screen environment requires more stringent than other environments, from raw materials to chip software, every detail is very strict.The unit price of outdoor LED screens is also higher than that of other commonly used LED screens.
