With the rising market demand for outdoor advertising, the rapid expansion of the application of the scale outdoor LED display. Faced with complex market brand products, industrial users to buy to how to make their own satisfaction with the product? To understand the parameters of the LED display is the primary prerequisite for the following electronic Jiangsu brightening give you have to analyze the parameters.
1. Definition: the required area determined in accordance with the best viewing distance point Screen clarity "40,000 pixels / m2" best distance of 5-50 meters; using the most advanced 16-bit data interface, to further improve the clarity of the screen degrees.
2. Brightness: Screen brightness designs 2500cd / m2 or more, not only to ensure the indoor full color LED display normal color fidelity, image clarity, but also to ensure that the LED display in the case of lamps with more than 30% attenuation time bright clear enough brightness and the video image. Refresh rate: The body of the screen between the processor and the Super Category 5 shielded twisted pair cable, configure high-performance control IC, high refresh rate screen body can be designed in ≧ 1000HZ, to ensure that no water ripples and flash video player, digital low loss, anti-electromagnetic interference. Power supply and signal transmission: because of the importance of full-color LED display, so the power supply and signal transmission to be technically special treatment, the use of high quality military grade connectors design. Further control failure caused by a variety of forces pulled in at the connector.
3, the control mode: use self-designed control system, and carry out 240 hours of uninterrupted power aging screening, and then select highly reliable control system. And dual redundant hot backup control mode, if there are problems at once, continue to operate normally from the other signal line access, smooth connection.
4, raw materials: LED display all the raw materials are made of high-quality brand-name products, the most important selection of high-quality LED lights LED lights;
5, three product aging process: First, automated assembly line production of modules energized aging for 24 hours, then 48 hours on a single box energize aging, final assembly of the finished display analog field 72 hours of continuous aging electricity, after passing through to delivered on-site assembly seat.
6, product quality control: All products strictly in accordance with ISO9001-2000 quality certification system files for product manufacturing. (See quality certification), will be in strict accordance with IP65 waterproof rating tests completely waterproof effect. LED display installation: in strict accordance with the design scheme LED display installation, the installation level reached C or above (LED display installed the highest level).
7, leading system software (equipment to screen the re-application): The operating system provides support for Microsoft Windows XP and Windows family of new products. All applications are Windows as the operating platform and user-friendly. Player software has a wealth of clock function, it can display the current date, current time, and time of the computer display clock can be synchronized simulation clock, or a digital clock. Software uses advanced threading technology when playing software can play multi-threaded text, animation, clock, photos, audio and so on.
8, sound system design (equipment to screen the re-application): The system can meet gatherings, performances, television and broadcast advertising requirements. The project LED display system with multimedia, multi-channel, real-time data transfer speed of communications and video interface, you can easily introduce various forms of information sources computer network system, to achieve a unified control of various audio and video inputs. Detailed functions are as follows:
9, video playback can display true color motion video; high fidelity closed-circuit television broadcast, satellite television programming; multiple video signal input and output interfaces: composite video, Y / C video (S_Video), YpbPr, VGA (RGBHV), DVI, HDMI ,, SDI (HDSDI); high fidelity playback video recorder, DVD player (VCD, DVD, LD) and other video programs; with superimposed text, animation and static pictures and other functions on the video screen; can be achieved by editing equipment panoramic, close-up, slow motion and special effects and other real-time editing and playback. Brightness, contrast, saturation, hue can be adjusted through the software, adjust the range of 256; having an image freeze functions; superimposed with video (VGA + Video), video (Video), VGA three display modes; a horizontal / vertical position compensation function; synchronization with the display.
10, computer graphic information playback can show all kinds of computer information, text, graphics, pictures and two, three-dimensional animation; has a wealth of playback mode, display scrolling messages, notifications, slogans such as, data storage capacity. Display body can open multiple windows, display a calendar, clock, text flow one-way spots. There are many Chinese fonts and fonts to choose from, you can enter many foreign languages English, Spanish, French, German, Greek, Japanese, Latin and Russian. Broadcast system with multimedia software, flexible import and broadcast a variety of information. Broadcast methods are rolling around, scroll up and down, left and right push, push down, push the diagonal, diffusion, fan-shaped, rotating, zooming and more than 20 species. Via a network connection, network data information. With a network interface, and computer networking, sharing of network resources, with standard audio signal output interface to audio and video synchronization.
