What is a LED?

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 a PIXEL?

By definition, the pixel is the “luminous dot” present on every LED device, from the simple alphanumerical Single Line display to FullColor maxi screens. This luminous dot can be formed by 1 or more LEDs depending on dimensions and features of the device. For example, on a small-size Single Line display, the pixel is formed by 1 single LED while on the king-size model the pixel can be formed by 20 LEDs. In some products, the pixel can be composed by up to 36 LEDs.
