Led module
LED screens are the latest method that is currently being used to promote products commercially, as they have many features that made them excel in attracting the audience, LED screens consist of a number of led module and are called several names, including (cells, tiles, or modules). Today we will review together the definition of the tile or the module and we will get to know together some important information related to its manufacturing process.
Definition of LED module in LED screens:
Led module
Definition :
The led module, or as it is called the slab, is the unit or cell that the screen consists of. It is a small board (PCB Board) on which all electronic components of LEDs and integrated circuits are installed, and these components are installed by tin soldering.
Manufacturing:
It is manufactured using modern production lines, machines and devices (SMT machines). There are different sizes and sizes of these cells, but the most common in external screens is the size of 16 cm in height and 32 cm in width for the cell or slab.
installation:
The led module are installed on the front surface of the module, and the rest of the electronic circuit elements are installed on the back surface.
Encapsulation :
The electronic board is wrapped with a polycarbonate frame, and the front end is protected by a mask made of the same material. Of course, all these parts and components differ in quality according to the factory and the manufacturing company.
Voltage:
In order for the led modules to work, they must be supplied with electrical energy, and all sizes and sizes share the fact that they work on one voltage, which is 5 volts. However, the amount of ampere varies according to the number of LEDs on the front surface of the tile, and the power supply inside the screen is responsible for converting electrical energy from 220 volts to 5 volts to feed the modules that make up the screen.
Function:
The function of the led module is to display the image that appears on the front of the screen, which is transmitted through the data cables connected to it through the rear ports of the module, which derives its signals from the main control unit of the screen.
8 Features that make you own LED screens:
Outdoor led display screen
The advantages of video screens are numerous and cannot be ignored in any way, so we will mention to you the 8 most important features of the electronic LED screen:
- Its life span is very long, up to 100,000 watch hours, with correct use.
- The use of modern LED technology does not make it consume much energy, so it helps to save electricity consumption.
- It is flexible, so it can be used anywhere you want, whether it is in an outdoor shop or in indoor banquet halls.
- Light weight can be moved easily.
- Easy to use in terms of programs that are set and broadcast at the time you want, and shows can be scheduled to run with time and date.
- It is characterized by hardness and withstands the sun’s rays and difficult climate changes.
- Highly luminous and very clear even in daylight.
- The screen is characterized by its ability to attract attention by 80% more than the traditional means of advertising.
What is the pixel pitch?
Pixel pitch it is the center-to-center distance of adjacent pixels measured in millimeters. A pixel indicates the gap between pixels of an LED display A smaller pixel pitch means that there is less empty space between pixels and there are more pixels, resulting in higher resolution and higher image quality.
The figure below shows the pixel pitch of a high definition SMD LED and a standard definition DIP LED. The pixel is a unit of measurement at the lowest point in the LED screens and has the same meaning as the pixel known in regular computer screens.
The greater the number of pixels in the screen, the clearer and more pure the image, and the screen resolution is the product of multiplying the number of pixels by length by width.
Example: A screen with a resolution of 1080 x 768 will result in 829,440 pixels.
Each pixel has a unique address, 8 bits in size, and most high-end display devices are capable of displaying millions of pixels. The smaller the distance between the LEDs or pixels on the screen, the higher the resolution and the greater the number of LEDs per square meter.
And the clearer and purer the image, the higher the cost, of course. The pixel pitch is the central distance between two LED units or two adjacent pixel units, and the smaller this spacing, the larger the illuminated distance and the clearer the image.
Pixel pitch is often referred to in the industry as P or Pitch, both of which have the same meaning as it is used to determine the spacing ratio between the LEDs, as described previously. Also known as dot matrix density, pixel density refers to the density of the number of pixels per square meter of screen.
Each square meter of the screen consists of a large number of independent pixels in its structure, and they can all form a giant LED screen, and the higher the density or in other words, the greater the number of LEDs per square meter, the greater the density and thus the clarity of the image. In width) and the result is the total point density per square meter.

Display components
Display screens contain a number of LED called “Module” cells, which are the same screen used in LED and are known as “pixels”. They are distributed within LED screens evenly and with the same accuracy, and this makes them provide the best possible quality in displaying content and give the best colors and the best possible viewing angle.
The term LED refers to “Light Emitting Diode”, which means the light-emitting diode, and the electric current passes through this LED, to provide the best possible quality.
One of the important advantages offered by the display screens is energy saving, as it is less energy consuming than the previous generations of screens, while maintaining the best possible quality, and works with high efficiency, and therefore it is the most widespread and most used, especially in the means of advertising, as it presents your content with the best possible quality as it works to attract target customers to serve you through its glow, brightness of colors and unique quality.
Display screens depend in their work on the passage of electric current passing through them, because they contain light emitting diodes, and these valves are composed of an anode and a cathode, and they are “anode – cathode” and both are separated at two different ends from each other.
With the connection of the electric current, then the atoms are quickly excited from the anode, as it is the highest in energy, and go to the cathode, which is the lowest in energy.
Thus, fusion of the crystal occurs in one direction, and electricity is connected to it as a whole in the form of a photon, and thus one of the light rays that has a specific frequency and accordingly has a wavelength as well as a specific color emitted by the LED, which explains the multi-color ability of the LED.
Advertising LED Display Application Scenarios
Advertising LED display screen is a modern high-tech product, which has the advantages of high visibility, high brightness and wider display information. Below are some common application scenarios.
Commercial place
The most commonly used scenarios in the commercial field are shopping malls, supermarkets, brand stores and other places. In these places, LED display screens can display merchants’ advertisements, sales promotion information, and new product promotions to attract consumers’ attention, quickly increase brand influence and sell products.
City landmarks
Outdoor led display screen
Obviously, outdoor LED large screens usually appear in urban core business districts, traffic arteries and densely populated areas. The superior location of these screens means that they have higher marketing value, whether it is brand promotion or business promotion of related companies.
Transportation hub
In transportation places such as airports, stations, and docks, LED displays screen are usually used for directions, introductions, and timetable inquiries, which play an important role in guiding people’s travel. In addition, the LED display also plays the role of advertising.
