1.What does UTP stand for?

UTP means unshielded twisted paired, it is a kind of net wire,also means RJ-45 to transmit the DVI signal.

2.What is The synchronous control system?

It means is not need the date wire and PC when it is playing, just edit the play files with computer first,then through a date wire copy it into the USB, CF Card,SD/MMC Card. And put the card into the receiving card external interface, then the screen will play the edited files.

3.What is the difference between the real and virtual pixels pitch?

The virtual pixel can achieve pixel share,(4LEDs) be 4-times pixel share, and (3LEDs) be 6-times pixel share.so it will be better effect to play pic or video,such as:the video has 320x240dots,if we display with virtual pixel then will be 640x480dots to display the video,more definition.

4.What is the weight of the cabinet (including all parts)?

For Steel Cabinet the weight less than is 65kg,and for Aluminium cabinet is 55kg, and the weight of 960mmx960mm Cabinet is 58 Kg(Steel),50 Kg(Aluminium) including all parts. 

5.What is Silan LEDs?

Silan LEDs is made in china, it is a public company with reliable quality.many of Display manufacturer are using(http://www.silan.com.cn/english/include/default.aspx) it.but you can point the LEDs aslo,like:Cree,Nichia or Avago.

6.What is sending card/receiving card?

Sending card to send the DVI signal (graphic card with the DVI singal interface transit the DVI singal to sending card) to the screen, receiving card+hub card to send the DVI signal to all modules

7.Where would the DVI cable be connected to?

DVI signal, Graphic card to sending card to receiving card+hub card to the screens. just use RJ-45 data wire to connect the sending card and receving card.

8.What is the use of graphic card and hub card and where would it be placed?

Graphic card is fixed in the PCI or VGA interface of the PC mainboard. the hub card fixed on the receiving card to extend the signal

9.What does the Driving Method mean?

Driving Method means use the Driving IC to control the LEDs, 1/1 scan means one pin to control one LED. it is usually used for outdoor. we have 1/2,1/4,1/8,1/16 for Indoor, because it will effect the brightness and consumption of the LEDs.

10.What does the Driving IC mean?

Driving IC means to control the LEDs current,LEDs usually the constant current 0.16mA to 1.2mA. so it is important for screen to use the good Driving IC, we used the TOSHIBA TB62726.

11.What does the Protection grades mean?

IP65 means waterproof and dust protection. so it can be used outdoor,if the IP54, then will be used indoor

12.What does the Gray grades mean?

Gray grades means one color from the most dark to most brightness 's grade. More Gray grades mean more color displayed and more definition.

13.What does the Refresh frequency mean?

The frame transform speed, more high,more comfortable when we are looking it.because there is no delay of the pic display

14.Will the product have an on/off switch or will it stay on as long as it is plugged?

We can turn the powe supply on/off through our control system software, so you can turn it on/off through the PC. We also can set when the screen be off and when the screen be on.

15.Can the images on this product only be updated by using the RS232 or can it be controlled from a different location via Bluetooth? How about a remote control?

Now, we have the asynchronism control system.   we have a receiving card in the Screen, it has integrated the Micro-System that has the function to store and play Video.  it have the external interface with USB, CF Card,SD/MMC Card to store the Video files.  you just need edit the video in your PC, and then copy it to the external equipment. it can play MPEG,AVI,RM,MP3 and so on. the total pixels it can control is 320x192 dots. so it can be used in the small screen.

Remote control pc can manage and monitor a group of led tv network through internet or lan.

16.How much of humidity can this product withstand?

The screen working humidity is 10%-95% RH and the working temperature is -20 to +60 degrees. it will be work normally in the atrocious weather.

17.What is a LED and a PIXEL?
LED is the acronym of Light Emitting Diode and it is a semiconductor that emits visible light when electricity pass through it. The emission of light depends on electrons flowing between anode and cathode and the color of the visual emission (that can be Red, Green, Blue, Amber, White…) depends on the material utilized.
18.What is the PITCH and RESOLUTION of the LED Display?
The pitch of a LED display defines the distance between the pixels, expressed in millimeters. This fundamental measure determines the characteristics and the performances of a LED maxi screens: the pitch indeed is a defining factor of a screen’s viewing distance.

19.What is the DEFINITION and the 16 BIT TECHNOLOGY?

The “definition” is the number of vertical and horizontal pixels that are on the entire screen. For example, some standard definitions are 96x64 pixels (=low definition); 256x192 pixels (=medium definition): 640x480 pixels (=high definition). The definition is therefore related to the pixel pitch, the distance between the pixels.
The Virtual Pixel is a technology of image management that allows visualizing pictures of a definition higher than the physical one, thanks to a technique called pixel interpolation? Virtual Pixel technology is able to control every single LED: this particular and exclusive screen management feature allows overlying every single pixel to the next one, creating a so-called Virtual pixel?(a pixel that does not exist but is perceptible by the human eye).
21.What are the differences between INDOOR and OUTDOOR Screens??
From a general point of view the difference between indoor and outdoor screens are the following: #1 – Resolution: as the outdoor screens are usually watched from greater distances, they do not need the highest resolution (from great distance the human eye do not discriminate small details anyways). The cost due to the big dimensions is therefore compensated by the lower resolution needed to provide a good image quality.
