What is an LED?

 light emitting diode (LED) is a tiny, electronic semiconductor that converts electric energy into visible light. The chemical compound used within an LED determines its color, brightness and power efficiency.

Unlike incandescent lamps, LEDs have no filaments that can burn out or fail. 

What is a pixel? (LED type)

Pixel is short for picture element. Pixels are points of light that illuminate together to form letters, words, graphics, animation, and video images.

A pixel can be made up of a single LED, multiple LEDs of the same color or multiple LEDs of different colors. A pixel is the smallest element of the electronic display system that can be individually controlled. It can be turned off or on at various brightness levels.


What is pixel pitch ?

Pixel pitch is the distance between pixels. So P10 means pixel pitch is 10mm, it is the same with P16,P20, etc. Pixel pitch varies from 0.7mm to 40mm, even 100mm.  


What is the LED module?

An LED module is a combination of parts that form the building blocks of LED video displays, message centers and dynamic message signs. Each LED module is composed by different pixel configuration, like: 32*32, 32*16, 16*16,20*20, 16*8, 8*8, etc.

IP rate(waterproof and dust proof level)


We usually see the ‘IP rating’ or Ingress Protection in the LED Display product advertising brochures, generally it defines the protection degree that the LED Display product should meet for the outdoor or long-time usage.
LED screens must be able to work 24 hours a day and 7 days a week and withstand extremely bad weather. For manufacturers it is required that the LED screens meet the criterion for outdoor LED screens IP65, and for indoor LED screens IP20. So what do these criterions mean? And what does IP65 and IP20 stand for?
The IP code (or International Protection Rating, sometimes also interpreted as Ingress Protection Rating) consists of the letters IP followed by two digits and an optional letter.
As defined in international standard IEC 60529, it classifies the degrees of protection provided against the intrusion of solid objects (including body parts like hands and fingers), dust, accidental contact, and water in electrical enclosures of the LED display screens. The standard aims to provide users more detailed information than vague marketing terms such as waterproof.
Let’s take some examples for detailed explanations:
Front Outdoor LED Screens: IP65

The first digit indicates the protection against dust. And "6" means Dust Tight, which means no ingress of dust and complete protection against contact. The second digit indicates the protection against liquids.The second "5" means: Water projected by a nozzle against enclosure from any direction shall have no harmful effects.

Back Outdoor LED Screens: IP54
The 2 digits indicate the same parameter with above. But the letters are different. And the first "5" means Dust Protected: Ingress of dust is not entirely prevented, but it must not enter in sufficient quantity to interfere with the satisfactory operation of the equipment; complete protection against contact. The second "4" means: Protected against splash water from any direction.

According to the "The General Criterion for LED Displays": Indoor LED displays should be IP20+, Outdoor LED displays should be IP33+,normally we make it IP65 front and IP43 rear, and if no back cover deign to protect the screen, then it should be IP65 front and IP54 rear.

Serviceability(maintenance method)

This means a way how to take out the module or the other components .

Most of the application , it would be rear service, and we suggest rear service. 

But in some installation case, there is not enough space on the back to open the back door of the cabinet, in this case we suggest front service. Not all the model have the solution of front service, please ask the technical for help if any requirement of front service. Also the cost would be different
