1. Clarity: Determine the required area of the screen based on the optimal viewing distance point, and the optimal distance for clarity of "40000 pixels/m2" is 5-50 meters; Adopting the most advanced 16 bit data interface, further improving the clarity of the image.
2. Brightness: The screen brightness design is above 2500cd/m2, which not only ensures the color realism and clear image of indoor full color LED display screens during normal use, but also ensures that LED display screens have sufficient brightness and vivid and clear video images when the lamp attenuation exceeds 30%. Refresh rate: Super Category 5 twisted pair shielded wires are used between the processor and the screen, equipped with high-performance control ICs. The high refresh rate of the screen can be designed at ≥ 1000HZ to ensure that there are no water ripples or flickers during video playback, low all digital loss, and anti electromagnetic interference.
Power supply and signal transmission methods: Due to the importance of full color LED display screens, special technical treatment is required for power supply and signal transmission, using high-quality military grade connector designs. Further control faults caused by various pulling and lifting forces at the connector.
3. Control method: Select a self-designed control system and conduct a 240 hour uninterrupted power on aging screening to select a highly reliable control system. And in terms of control mode, dual redundant waste heat backup is adopted. Once problems occur, another signal line is immediately connected to continue normal operation and smooth connection.
4. Raw materials: All LED display screens are made of high-quality products from well-known brands, and the most important LED lights are made of high-quality LED lights.
5. Third level product aging process: Firstly, the modules produced by the automated assembly line are subjected to 24-hour power aging, followed by 48 hours of power aging on a single box. Finally, the simulated on-site assembly of the finished display screen is subjected to 72 hours of continuous power aging. Only after passing the qualification can it be transported to the site for assembly.
6. Product quality control: All products are manufactured strictly in accordance with the ISO9001-2000 quality certification system documents. (See the quality certification certificate), all will be strictly tested according to the waterproof grade IP65 to achieve complete waterproof effect. LED display screen installation and debugging: Strictly follow the design plan for LED display screen installation and debugging, and the installation level should reach level C or above (the highest level of LED display screen installation).
7. Leading system software (ready for screen re application): The operating system adopts Windows XP and supports the latest Windows series products provided by Microsoft. All application software is operated on Windows and has a user-friendly interface. The playback software has rich clock functions, which can display the current date and time. The display clock synchronized with the computer's time can be a analog clock or a digital clock. The software adopts advanced threading technology, and can play text, animation, clock, photos, audio, etc. in multiple threads during software playback.
8. Perfect system functional design (ready for screen re application): This system can meet the requirements of gatherings, performances, television broadcasting, and advertising broadcasting. The LED display system of this project has multimedia, multi-channel, and can transmit high-speed communication data and video interfaces in real-time. It can easily introduce various forms of information sources into the computer network system, achieving unified control of various audio and video inputs.
9. The video playback function can display True color dynamic video images; Can broadcast closed-circuit television and satellite television programs with high fidelity; Multiple video signal input and output interfaces: composite video, Y/C video (S-Video), YpbPr, VGA (RGBHV), DVI, HDMI, SDI (HDSDI); Can play high fidelity video programs such as VCD, DVD, LD, etc; Capable of overlaying text, animation, and static images on video screens; Real time editing and playback functions such as panoramic, close-up, slow motion, and special effects can be achieved through editing devices. Brightness, contrast, saturation, and chromaticity can be adjusted through software, with an adjustment range of 256 levels; Equipped with image freezing function; It has three display modes: video overlay (VGA+Video), video (Video), and VGA; Equipped with horizontal/vertical position compensation function; Has display synchronization function.
10. The computer graphics and text information playback function can display various computer information, such as text, graphics, pictures, and 2D and 3D animations; It has rich playback methods, displaying scrolling information, notifications, slogans, etc., and has a large storage capacity for data information. The display screen can have multiple windows, displaying calendars, clocks, and inserting single line flowing text. There are various Chinese fonts and fonts to choose from, and you can also input many foreign languages such as English, Spanish, French, German, Greek, Japanese, Latin, and Russian.
The broadcasting system has multimedia software that can flexibly input and broadcast various information. There are more than 20 broadcasting methods, including left and right scrolling, up and down scrolling, left and right pushing, up and down pushing, diagonal pushing, diffusion, fanning, rotation, scaling, etc. Display network data information through network connection. Equipped with a network interface, it can connect to computers and share network resources. It has a standard audio signal output interface to achieve audio image synchronization.
