Ten aspects let you understand outdoor LED display screen
Ten aspects let you understand outdoor LED display screen
With the increasing requirements of the advertising market for outdoor advertising media, the scale of outdoor applications is rapidly expanding. For the uneven brand of LED display products on the market, you need to understand the 10 main technical parameters of the LED display, and improve the ability to recognize the LED display products.
1, clarity:According to the best viewing distance point to determine the screen body required area, clarity. The best distance is 5-50 meters; using the most advanced 16-bit data interface to further improve screen clarity.
2, Brightness:2500cd/m2 or higher screen brightness, so that you can enjoy the real color and clear images in the indoor LED full color display screen normal work, while the LED full color display screen can clearly display more than 30% of the brightness and video images. Refresh rate:There are 5 types of dual screens between processor and screen body, which constitute a high performance control IC.The high refresh rate of screen body is designed for 1000HZ, no wave and flicker during video playback, less digital loss, and electromagnetic interference
resistance is low. Power and Signal Transmission Methods:Due to the importance of full color, power and signal transmission are technically handled in a special way, using high quality military grade connector design. Further control of various lifting-induced errors.
3, control methods:Selection of independently designed control system, 240 hours of uninterruptible power supply aging screening in order to select a highly reliable control system. Redundant hot backup can be immediately connected to another signal line in the event of a problem, continue to work normally and maintain a seamless connection.
4, raw materials:All raw materials use brand quality products, the main LED lights use high quality LED lights.
The 5th and 3rd stage product aging process:24 hours of power aging after a single box 48 hours of power aging, and finally on-site assembly to complete the display continuous 72 hours of power aging, after assembling through the site location.
6, product quality control: all products are in strict accordance with the ISO9001-2000 quality certification system documents manufacturing products. (Please refer to the quality certification certificate.) Strictly comply with the waterproof level IP65 test to obtain completely waterproof effect.LED full-color display installation and commissioning: LED full-color display installation and commissioning according to the design of the strict implementation of the installation level is higher than the level of c (LED full-color display installation of the highest level).
7, the main system software for screen playback
:The operating system uses WindowsXP and supports the latest Windows series provided by Microsoft. All applications use Windows as the operating platform, and the interface is familiar. The playback software has a variety of clock functions that can display the current date, current time, a display clock synchronized with the time on the computer, or a digital clock. The software uses advanced threading technology in the playback software can be multi-threaded text, animation, clock, photos, audio and so on.
8, complete system functional design (for screen playback): the system to meet the requirements of rallies, performances, television broadcasts and advertising broadcasts. This project LED display system can real-time delivery of multimedia, multi-path, high-speed communication data and video interfaces, so that you can easily introduce multiple forms of information sources into the computer network system, so as to realize the unified control of a variety of audio and video input.
9, video playback function can display true-color dynamic video images. Can playback closed-circuit television and satellite television programs. Composite video, Y/C video (S_Video), YpbPr, VGA (RGBHV), DVI, HDMI, SDI (HDS di); able to playback VCRs, video drives (VCD, DVD, LD) and other video programs in high definition. Ability to overlay text, animations and still pictures on the video screen. Editing devices enable you to realize real-time editing and playback features such as panoramas, close-ups, slow-mo, stunts, and more. Brightness, contrast, saturation and chroma can be controlled by the software with an adjustment range of 256 levels; with image freeze function. There are three display modes: video overlay (VGA Video), image (Video) and VGA. with horizontal/vertical position correction function. With display synchronization function.
10, computer graphics information playback function can display a variety of computer information, including text, graphics, pictures and two-dimensional and three-dimensional animation. Display scrolling information, reminders, slogans catchphrases, etc. playback method is rich, storage data information capacity. The display body can open multiple windows, display calendars, clocks and insert single-line streaming text. You can choose from a wide range of Chinese fonts and typefaces, as well as input many foreign languages, including English, Spanish, French, German, Greek, Japanese, Latin and Russian. The broadcasting system has multimedia software for flexible input and broadcasting of various information. There are more than 20 types of broadcasting methods, including left and right scrolling, up and down scrolling, left and right push, up and down push, diagonal push, diffusion, fanning, rotation, and zoom. Display network data information through network connection. You can connect to your computer through the network interface to share network resources and synchronize the output through standard audio signals.
