LED Signs knows that Display Systems have their fair share of acronyms, abbreviations and curious product descriptions.

This article is here to help you understand the terminology of  Display Systems so that you can make a more informed choice when it  comes to purchasing a display.

  • LED: A light-emitting diode (LED) is a semiconductor device that emits visible light when an electric current passes through it. This device is the most important element of an LED display.
  • VMS: All programmable LED displays can be described as variable message signs (VMS). This means that regardless of the type – scrolling text sign, full colour graphic display or LED video screen – all displays use control software that turn the LED's on and off in sequence, creating a changeable or variable text, graphic or video sign.
  • Pixels: Pixels are made up of one, or a cluster of, LEDs that create a single point of light or colour. Resolution, which is influenced by the pixels and pitch of the screen, is an important thing to consider when selecting a fit-for-purpose LED display.
  • Pitch: The pitch of the display is the distance between the centre of two pixels.Resolution, which is influenced by the pixels and pitch of the screen, is an important thing to consider when selecting a fit-for-purpose LED display.
  • Visibility Angle: The visibility angle is the angle at which the clarity of the display is equal to 50% of its frontal luminosity.
  • DIP:  Dual Inline Package (DIP) is a type of display in which the LEDs are attached to the circuit board with two parallel pins.
  • SMD: Advances in LED technology resulting in the ability to miniaturise the diode’s electrical components has seen the introduction of Surface Mounted Diode (SMD) displays. These significantly smaller LEDs can be mounted so that they are almost flush with the surface of the electronic board.
