GKGD LED display as the market is on the rising demand for outdoor advertising, outdoor LED display used in the rapidly expanding scale.
With a brand of product on the market, users who want to how to choose and buy to let oneself satisfactory products?
We must first understand the LED display of the parameters is the primary premise.
1, the definition: according to the point of the best viewing distance is determined the screen area, resolution is 40000 pixels/m2, the best distance for 5 -
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, not only can assure indoor full color LED display is normal 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 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, control mode: choose the independent design of control system, the aging and 240 hours of uninterrupted power supply 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 LED Light module
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 certificate)
, will be in strict accordance with the waterproof grade IP65 test, achieve completely waterproof effect.
LED display installation and debugging: strictly according to the design scheme of LED display installation and debugging, installation level reaches more than class C (
LED display is installed the highest level)
7, leading system software (
Prepare 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, perfecting the 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.
Detailed functions are as follows: 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
Can high fidelity broadcast video recorder, VCD,
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 (
, image (
And VGA display mode;
With horizontal/vertical position compensation function;
With functions of display synchronization.
10, computer graphic information broadcast function can display a variety of computer information, text, graphics, pictures, and second, the three dimensional animation, etc. ;
Broadcast has rich, display scroll, notification, slogans, etc. , large capacity of storage data information.
The screen body can open multiple Windows, according to the calendar, clock, air flow line text.
There are many Chinese font and font to choose from, also can input English, Spanish, French, German, Latin, Greek, Japanese and Russian, and many other foreign language.
Broadcast system with multimedia software, flexible input and broadcast a variety of information.
Broadcast way around a scroll, rolling up and down, left and right drive, drive up and down, diagonal drive, diffusion, fan type, rotation, scaling and so on more than 20 kinds.
Through the network connection, network data information.
To equipped with a network interface, and computer networking, sharing network resources, has a standard audio signal output interface to audio and video synchronization.
