Indoor two elementary colors display screen

● System consist of display screen , DVI display card, control card synchronism, data transmission line, supply power’s power, outer equipment and systems software, etc.

1. The display screen makes red and green LED as light display component which with driving circuit, data dealing together make up of display unit module that form matrix type display screen. It is equivalent to zoom out the display

2. Control computer is special-purpose to control machine of display screen, which inserts DVI display card, Synchronism controlling card to realize to the display screen controlled in step , the user can choose various kinds of brand machines and compatibles machine.

3.DVI display card adopts the digital video interface shows the card special-purposely as LED display screen which have more superior performance of display card than traditional simulation

4. the control card of synchronism is a data collection delivering card of synchronism which is designed by our company. It has function of data collection, tone counterchange, non-linear varying, luminance adjust etc.

5． Data transmission line uses strong anti-interference ability of exceed the fifth kind twisted-pair(each has eight core) which guarantees the data has no error in the transmit ion.

6． According to users’ requirement, outer equipments can meet other equipments, such as video cassette recorder, video disc machine, video recording machine, television receiver, etc. And it supports many kinds of rules, such as NTSC, PAL, S_Video, etc. Such as the computer disposes sound card, outer works set sound box which can realize the export of sound frequency signal.

7． After the power steady, according to rated load condition, meeting to each area of display equably for LED display to provide with electric power supply on the safe side.

8．System software supply with LED plays special-purpose software or PowerPoint and carry on other special required software.

● system function

This system has function as follows:
1. it can realize 1024x768 display mode: Regard computer as the control center. Electronic screen Corresponding piecemeal in electronic screen and a certain area of the window of display of computer(VGA), show the real-time synchronism of display content , Screen shine upon position can adjust, and can have been convenient to choose and show the size of the picture at will.

2. Real 256grey scale: display lattice adopts much high brightness LED light tube (dual basic color of red and green) to realize gray degree of 256 grades. Combination of color variety has 65536 kinds. The color is abundant and realistic. The single color chroma of red and green can adjust.

3.scan frequency is over 200Hz: using over 200Hz frame scan frequency will have good vision effect. People’naked eye nearly can’t see the scan line.

4． the software realize JIAMA adjust: it realizes proofread design of no gray degree grade loss. After proofreading JIAMA, it still keeps gray degree of 256 grades per basic color so that the color of photo is soft, reality and better to recur level sense and three-dimensional effect. Its proofreading parameter can be chosen by users at will so that it can realize breezily every kinds of gray degree grade adjusting and brightness controlling function, which makes the LED screen show the best display effect under ray of different environment.

5． The making and playing software of advanced and perfect program: It allocates advanced and perfect controlling, making and playing software. It is special-purpose program which is easy to study and use. Which you see is the editing interface and possesses the long-range control ability so that it is convenient for non computer professional personnel to master quickly and operate expertly. The allocated graphics content information and three-dimensional cartoon play software, can broadcast them high-quality. The display modes of play software have over 10 various forms of cover, close up, turn on curtain, color replace, enlarge, shorten etc. Software of editing and making program can edit, add, delete and change characters, figure, picture, etc. by keyboard, mouse, scanner, etc.

6． it can receive and display the video signal: such as video cassette recorder, video disc machine, television, etc...

7． High integration degree of system design: the system design is advanced, reasonable. The display effect is stable. Installment maintains is convenient.

8． Possess the switch machine of computer automatic black screen function: through disposed by software, it has avoided the display interface disorderly and unsystematic when switching the computer. And the display screen will at black screen condition so that increase the life of display screen.
