Your Guide to LED Technology and Terminologies

What is LED?

LED is an abbreviation for light-emitting diode. LED devices are semiconductor components that generate light when electricity flows through them. In the past, the red (R), green (G), and blue (B) colors were often represented by separated LED bulbs. These three bulbs are combined to form a pixel. The distance between each pixel is called pixel pitch. The number of pixels per square meter is called pixel density. Higher pixel density commonly results in a higher image quality displayed on the LED screen.

The evolution of the LED display industry led to increased demand for higher resolution and pixel industry products. Traditional bulbs have faced limitations due to their sizes. Thus, surface-mounted device (SMD) LED technology is born. It integrates the red, green, and blue colors in a single device. This innovation enables the production of higher-resolution LED displays.

What are LED Modules?

LED modules are the basic building blocks of an LED display. It contains the LEDs themselves along with other necessary components such as power supplies, controllers, drivers, and more. With these components, the LED display can generate high-quality videos and images by using a system card. Pixel pitches have a variety of LED module sizes whether vertical or horizontal. These sizes include:

  • 320mm x 120mm
  • 240mm x 240mm
  • 192mm x 192mm
  • 160mm x 160mm
  • 250mm x 250mm
  • 256mm x 128mm, and more

What is an LED Cabinet?

LED cabinets are essential housing units that contain the installed system card, power supply unit, and LED modules. The LED cabinets are the smallest functional component grouping within the entire LED display. When ordering an LED display, you will typically receive them in multiple cabinets that are assembled to form the complete LED screen.

LED cabinet sizes vary depending on your desired resolution and screen size. When you order an LED display, the manufacturer will calculate and recommend the best cabinet sizes to achieve the desired screen dimensions. Thus, assuring that the final display meets your project requirements.

What is an LED Screen?

LED displays stand out especially in the commercial market due to their energy efficiency. They also consume a very low power. Thus, making it energy-saving.

LED displays are composed of LED panels containing multiple LEDs. Unlike other light sources, LED display offers greater intensity and brightness.
