1, the definition: according to the best viewing distance point determine the screen area, resolution is “40000 pixels/m2” optimal distance of 5 to 50 meters; Using the most advanced 16-bit data interface, further improve the clarity of the picture.
2, brightness, screen design in more than 2500 CD/m2 brightness, can not only ensure the normal order of the P5 indoor full color when using color fidelity, image is clear, and can ensure that the LED display tubes attenuation under the condition of more than 30% have enough brightness and video images of bright color.The refresh rate: between the processor and the screen body is made of super five types of twisted-pair shielded wire, high-performance control IC, can design high refresh rate screen in ≧ 1000 hz, in order to ensure that when the video playback without water ripple and flashing, full digital low dissipation, resistance to electromagnetic interference. Power supply and signal transmission way: because of the importance of full-color outdoor led display, so the power supply and signal transmission to special treatment on the technology, using high quality level of military connector design. Further in the connector control failure caused by different kinds of pull the lift.
3, the control mode: choose the independent design of control system, and on 240 hours of uninterrupted electrical aging filter, and then choose the highly reliable control system. And on the control mode with double redundant heat backup, once appear problem by another line access immediately, continue to work normally, the smooth connection.
4, raw material: LED display all the raw materials are choose famous brand high-quality products, the main LED lights use high quality LED light.
5, level 3 products aging process: first, the module of automated assembly line production electricity 24 hours aging, then 48 hours on a single box electricity aging, finally simulation finished assembly at the scene display electricity aging 72 hours straight, after they are qualified to arrived at the scene seat assembly.
6, the product quality control: all products in strict accordance with ISO9001-2000 quality certification system files for product manufacturing. (see quality certification), will be in strict accordance with the waterproof grade IP65 test, achieve completely waterproof effect. LED display installation and debugging: LED display installation and debugging in strict accordance with the design, installation level reaches more than class C (installation LED display the highest level).
7, leading system software (for) to screen and application: with Windows XP operating system and provided support for Microsoft Windows series of new products. All applications for Windows operating platform and friendly interface.Player software is rich in the clock function, it can show the current date, the current time, and time synchronization of computer display simulation clock, the clock can be also can be a digital clock. Threads software is installed with advanced technology, can multithreaded played when player software text, animation, clock, photos, audio, etc.
8, the consummation system function design (prepare) to screen and application: this system can meet the assembly, performance, and advertising on TV broadcast. This project LED display system with multimedia, multi-channel, can real time transmission of high-speed communications, data and video interface can be easily introduces a variety of information sources in the form of the computer network system, to achieve unified control of all kinds of audio and video input.
9 dynamic video, video playback function can show true color images; Can high fidelity on closed-circuit television, satellite television; A variety of video signal input/output interface: composite video, video Y/C (S_Video), YpbPr, VGA (RGBHV), DVI, HDMI, and SDI (HDSDI); Can hi-fi playback video, DVD, VCD, DVD, LD) such as video programs; Have on the video image superposition character, animated and static images, and other functions; By editing the equipment can realize panorama, close-up, slow motion, and special effects such as real-time editing and broadcasting functions.Brightness, contrast, saturation and chroma can be regulated through software, the adjusting range is for grade 256; With functions of image freeze; A Video superposition (VGA + Video), image (Video), VGA display mode; With horizontal/vertical position compensation function; With functions of display synchronization.
