Such structures are arranged according to a modular principle. Each LED screen module consists of dots – pixels, which contain a different number of LEDs. When an image is formed, the luminous points merge, and we see a static picture or dynamic video content. The information on the display comes from a computer in which the program supplied with the electronic device is installed. The software allows you to upload content, create picture-in-picture use other effects, and plan video schedules. Modern computers connected to LED technology broadcast images from any electronic media, camera, Internet, or TV tuner.


There are several types of LED video screens, differing in design and scope of application. This variety allows you to choose the best option for displaying any images.

  • SMD screens

SMD media devices consist of new generation LED, the bulb of which contains three crystals of basic colors. The luminous elements are mounted directly on the board – closer than on DIP models, so the video image is detailed.

SMD screen not as bright as DIP screens, but the picture displayed on them does not seem to consist of dots. This option is suitable for indoor installation. The interior LED screen differs in its operating conditions. The potential recipient of your information message, as a rule, looks at the display from a close distance, often coming almost close to the video plane of the screen. For this reason, the quality (resolution) requirements for indoor LED displays are quite stringent. The broadcast image has no right to scatter into pixels and should be perceived equally comfortably from 20 meters as from 3-5.

Thus, when choosing a modification of an LED screen for a room, the most important indicator is the quality of the broadcast image. The smaller the “step” of the LED display (the distance between the diodes), the higher the resolution of the video screen.

  • Cluster screens

These displays consist of clusters – sealed blocks with different numbers of LED. Each cluster element is equipped with a semiconductor substrate with electronic elements connected to the control board. Clusters can be used to create flexible media facades mounted on walls, roofs and other building elements.

The main disadvantage of such media devices is large clusters. Therefore, structures are mounted at a distance, for example, on top of a building or object located at a great distance. Then the image looks harmonious.

  • Matrix screens

In this design, clusters are combined with LED, a substrate and a control board. Each module is connected to an information bus through which control is carried out. This makes matrix options durable, reliable and secure. Gradually, such video screens are replacing outdated cluster ones.

  • DIP screens

In these models, the light sources are DIP light elements, consisting of a miniature bulb with a colored crystal and “legs” for attachment to the matrix. The LED’s are installed at a certain distance from each other, so up close the image breaks up into dots. But from a distance everything looks great – the DIP elements glow brightly, the picture turns out colorful.

Interior LED screens, as a rule, are assembled on matrices with a pixel pitch of P 5, P 4, P 3, P 2.5 or less. At the moment, in terms of price/quality ratio, the most popular modifications are P 5 and P 4, since smaller pitch modules are significantly more expensive than these models.

The LED interior screen is mounted either on a wall or in a display case. In the latter case, you should take into account the dimensions of the modules, which determine the final dimensions of the LED screen. It is necessary to achieve maximum filling of the glass area so that the display looks harmonious behind the glass and provides the highest possible information efficiency. Thus, the P 5 module is a rectangle measuring 320×160 mm.
