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....................

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:...... Details |
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. ........ Details |
What is the VIRTUAL PIXEL TECHNOLOGY and CONTRAST LEVEL? |
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)....

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.......... Details |
