With the market demand for outdoor advertising continues to improve, outdoor LED display application of the rapid expansion of the scale. The face of the market brand of complex products, industry users how to choose to buy their own products to understand? Understand the LED display of the parameters is the primary premise.
1, clarity: according to the best viewing distance to determine the screen area required, the definition of "40000 pixels / m2" the best distance of 5-50 meters; using the most advanced 16-bit data interface, to further improve the picture clear degree.
2, brightness: screen brightness design in 2500cd / m2 or more, not only to ensure that the indoor full color LED display normal use when the color realistic, clear images, but also to ensure that the LED display in the lamp attenuation of more than 30% Enough brightness and clear and clear video images. Refresh rate: between the processor and the screen through the super 5 class twisted shielded cable, configure the high-performance control IC, the screen can be designed to refresh the high rate of ≧ 1000HZ to ensure that the video playback without water ripples and flashing, Full digital loss is low, anti-electromagnetic interference. Power supply and signal transmission: Because 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 connector design. And further control the various pull-off at the connector caused by the failure.
3, the control mode: the use of self-designed control system, and 240 hours of continuous electricity aging filter, and then select a highly reliable control system. And in the control mode using dual redundant hot backup, once the problem immediately by another signal line access, continue to work properly, smooth connection.
4, raw materials: LED display all raw materials are selected brand-name quality products, the most important choice of high-quality LED lights LED lights;
5, three products aging process: the first automated production line of the module 24 hours of electricity aging, and then a single box for 48 hours of electricity aging, the final simulation of the finished assembly of the finished product for 72 hours of continuous aging, qualified after the Arrived at the location of the assembly.
6, product quality control: all products in strict accordance with the ISO9001-2000 quality certification system for product manufacturing products. (See quality certification), will be strictly in accordance with the waterproof rating IP65 test, to achieve full waterproof effect. LED display installation and commissioning: in strict accordance with the design of the LED display installation and commissioning, the installation level to C above (LED display installed the highest level).
7, the leading system software (available in the screen and then apply): operating system using Windows XP and support Microsoft's latest series of Windows products. All applications are Windows-friendly and user-friendly. Playback software has a rich clock function, it can display the current date, the current time, synchronized with the computer clock display clock can be analog clock, it can be a digital clock. The software uses advanced thread technology, in the play software can be multi-threaded playback of text, animation, clock, photos, audio and so on.
8, the perfect system function design (available in the screen and then apply): The system can meet the rally, performance, television and advertising broadcast requirements. The project LED display system with multimedia, multi-channel, real-time transmission of high-speed communication data and video interface, you can easily put a variety of forms of information into the computer network system, to achieve a variety of audio and video input unified control. The detailed functions are as follows:
Multi-video signal input and output interface: composite video, Y / C video (S_Video), YpbPr, VGA (RGBHV), a variety of video signal input and output interface: composite video, Y / C video (S_Video), YpbPr, VGA (RGBHV), video recording function can display true color dynamic video images; DVI, HDMI, SDI (HDSDI); can be high-fidelity video recorder, DVD player (VCD, DVD, LD) and other video programs; with the video screen superimposed text, animation and static pictures and other functions; through editing equipment can be achieved Panorama, close-up, slow motion and special effects such as real-time editing and playback. Brightness, contrast, saturation, color can be adjusted by software, adjust the range of 256; with image freeze function; with video overlay (VGA + Video), video (Video), VGA three display modes; with horizontal / vertical Position compensation function; with display synchronization function.
10, the computer graphic information playback function can display a variety of computer information, text, graphics, pictures and two, three-dimensional animation, etc .; has a rich playback mode, display rolling information, notification, slogans, etc., storage data information capacity. The display body can open multiple windows, display calendar, clock, and span single-line mobile text. There are many Chinese fonts and fonts to choose from, you can also enter the English, Spanish, French, German, Greek, Japanese, Latin and Russian and many other foreign languages. Broadcast system with multimedia software, can be flexible input and broadcast a variety of information. There are more than 20 kinds of broadcasts, such as rolling around, rolling up and down, pushing up and down, pushing up, dipping, spreading, fan, spinning and zooming. Through the network connection, display network data information. Equipped with a network interface, can be connected with the computer network, shared network resources, with standard audio signal output interface to achieve audio and video synchronization
