Led screens as well as other kinds of led light are used more often. This is due to many advantages such as light-emitting diodes consume little energy they can be used to create high-tech solutions in particular flexible or transparent LED screen.

<--noindex-->

The operation of such equipment is based on the technology of led which is a semiconductor element featuring a very compact size. When applying electric current to the LED design, the diode will glow.

Another feature of led screens is usually characterized by a large area but they consist of a plurality of light sources each of which is a light emitting diode and forms a pixel. To design working as their base module is used on the back side of which are mounted the electronic components and the top LEDs are one or more depending on performance.

LED screens can be used in various purposes. But first of all their uses as billboards as well as a Bulletin Board. Very popular to use led screens for show organization of ideas concerts entertainment and sports events.

First of all, the division into groups takes into account the purposes of these structures

The difference between them lies in the degree of protection to the screen surface. So street LED devices of this type are able to withstand any weather conditions snow rain dust and wind without loss of image quality. Hinders direct sunlight because the matte black surface LED design absorbs all the light. Street performance differ according to the parameter as the pixel pitch. Its value varies from 10 to 25 mm.

Led screens for outdoor use are different is another key feature of every constructive element of the module is closed by a body called the Cabinet. With such a casing protects the electronics from external factors. The range of values of temperature of devices of this type is very wide-from -40 to +85 degrees. Thanks to these features of the street performance can be used in different climatic zones.

Screen design

Led screens for indoor installation there are a number of options, such construction does not provide a light-proof visors, their angle of vision is very wide up to 140 degree vertically and horizontally. It is important to understand that both options are interchangeable but only if you want to install outdoor screens in the room while internal execution must not be operated outside of the room.

According to the method of installation distinguish

There are also different types of different spectrum light emitting diodes

If the device of this type, each module contains several colored diodes it is a full color. In this case, it is much easier to achieve a certain hue of the image. There are more simple execution which differ in that each module contains only one light emitting diode.

Guided by structural and technological differences between these devices are divided into the following groups

The cost of the second option is much less flexible but are performed with the use of high technology, respectively, and are offered at a high price. There are different variants of such structures in the form of a mesh transparent led screen at the pipes and rails. In each case the technique is intended for use in specific purposes.

For example, flexible and transparent execution is set on the glass that simultaneously allows you to put a picture in the window or other surface and will not affect the view of the room.

Should simultaneously pay attention to several characteristics to ensure a sufficient level of visibility and image quality

Is considered for the selection and the quality of light-emitting diodes. The most expensive of the currently available options Nichia Cree. They also considered the quality of the whole range.

Aspect ratio

Followed LED product brand Samsung Epistar Absen. The cost of such equipment depending on parameters pixel pitch which is based on the module brightness viewing angle and so on varies in the range from 30 000 to 125 000 RUB. per 1 sq. m.

Given the relatively high cost I'm sure many people thought about the is it possible to make the led screen with his hands. And really to save money and get a functioning but modest external characteristics of the design it is sufficient to stock up a certain amount of led strips, microcontroller, power supply unit and fastening elements.

As you plan to use quite a large number of light sources is necessary to devise a cooling system which will be panels with aluminum coating.

LED light sources are attached by means of plastic elements which in turn are mounted on the working surface with screws. You must use the measuring tape during installation that will make the incisions as accurately as possible.

To get the design for all working environments need to pick up the ribbon to the desired degree of protection IP65 IP67 IP68. Ready-made screens led module is protected by a case he's office.

Therefore, when you select should pay attention to the following key parameters of the viewing angle the brightness level of the image pixel pitch of structural features such as protected led module housing. It is equally important to consider the quality of light sources because this will depend on the duration of construction.
