WHAT IS LED?

An LED display consists of many closely-spaced LEDs. By varying the brightness of each LED, the diodes jointly form an image on the display.

To create a bright colour image, the principles of additive colour mixing are used, whereby new colours are created by mixing light in different colours. An LED display consists of red, green and blue LEDs mounted in a fixed pattern. These three colours combine to form a pixel. By adjusting the intensity of the diodes, billions of colours can be formed. When you look at the LED screen from a certain distance, the array of coloured pixels are seen as an image.

WHAT IS RGB?

RGB is short for Red, Green and Blue. It is a colour scheme that exploits the fact that all visible colours can be mixed from these three basic colours. It is used in almost all types of displays, including LED displays.

WHAT IS SMD?

SMD stands for Surface Mount Device. These electronic components are directly mounted on the surface of a printed circuit board, rather than soldering their metal pins underneath the board as was done traditionally.

In the realm of LED display technology, SMD takes on a slightly different application. An SMD LED display incorporates red, green, and blue diodes that are encased in a small plastic package. This package is then surface-mounted onto the printed circuit boards that make up the display. The encapsulation of the diodes in this manner allows for a more compact design, enabling the creation of displays with smaller gaps between diodes and, consequently, higher resolution.

HOW MUCH POWER DOES AN LED DISPLAY USE?

LED technology is renowned for its high energy efficiency, which explains the widespread adoption of energy-saving LED bulbs in recent times. The power usage of the diodes in an LED screen varies based on the display type, brightness settings, and frequency of use.

The content displayed also affects power usage. A completely white screen will consume more power compared to white text on a black background.

HOW LONG DOES AN LED DISPLAY LAST?

Generally, with appropriate care and maintenance, LED displays can remain functional for over a decade. The longevity of these displays is impacted by frequency of use and environmental conditions. Lighter images and higher brightness levels tend to shorten display life.

WHAT IS PIXEL PITCH AND DISPLAY RESOLUTION?

The resolution of an LED display is influenced by the distance between its diodes, referred to as pixel pitch. Pixel pitch is measured from the center of one group of diodes to the center of the adjacent group. This distance impacts the overall resolution of the display.

WHAT RESOLUTION SHOULD I CHOOSE?

The key factor in choosing LED resolution is viewing distance. Displays meant for close viewing, like in shops, benefit from high resolution. Outdoor signs far from viewers may not require such detail. A useful rule: 1 mm pixel pitch per meter of viewing distance.
