In order to get clear images from long distances and side angles in large areas indoors, LED screens have replaced LCDs in recent years. Depending on the distance from which the screen can be seen and the size of the screen, products with different pixel ranges can be selected.

In previous years, P5 and P4 were mainly used in interior spaces, but recently P3, P2.5, P2 and even P1.86 panels have also been preferred. In some special projects, P1.66, P1.53 and P1.25 panels are used (Led Agency uses P2 mainly in desktop menuboard / menuboard LED screens, but has used P1.25 panels upon special request). Again, in previous years, P6 panels were preferred a lot due to the fact that the cost price between P6 panels and P5 panels was very close; with the developing LED and LED screen technology, P6 panels are almost never used in LED screens in the market, and P5 panels are preferred in larger scale LED screens or lower budget jobs. As Ledajans, we mainly use P2 and P2.5 modules in indoor LED screens, and in module sales, we sell P2.5 indoor LED screen modules the most. Poster Led Screens / Racket Led Screens mainly use 64×160 cm and 64×192 cm vertical, magnetic/magnet structured cases along with P1.86, P2 and P2.5 RGB led modules. While live broadcasting can only be done with the help of a processor in indoor Led Screens; With the addition of processor feature to asynchronous cards by companies producing Led Screen control cards (such as Novastar and Huidu), Led Screen control cards have become both synchronous and asynchronous and have become capable of providing live broadcasts by dimensioning without a processor. Examples of these Led Screen control cards include Novastar TB1, TB2, TB3, TB4, TB6, TB8 Taurus series cards and Huidu series HD-A4, A5, A6 series Led Screen control cards, which are mostly used in Led Screens in Turkey. If we add, Huidu company can show live broadcast and video images loaded into its memory etc. simultaneously on a Led Screen with the new feature they brought to the A4, A5 and A6 Led Screen control cards, in this way Led Screens can be separated into pixel sizes and used for different purposes and different images. In addition, sound system, heat sensor, humidity sensor, wind sensor, pressure sensor can be integrated according to preference. In indoor Led screens, fanless smps are generally preferred for thin casing and noiselessness. Indoor Led Screens naturally need less power and less power supply / power supply adapter due to the increase in scan / scan rate and lower current draw of the used LEDs, generally 1 200-5 (40 ampere) power supply / power supply adapter is used for 8 indoor Led Screen modules in indoor Led Screens.

As Led Agency, we use Youyi and GKGD brand adapters in our Led Screens, and we also use Meanwell brand power supply adapters in some Led Screen projects upon request.

All companies say that the Nationstar brand is used for LED chips used in LED screen panels, and almost all companies say that LED chips with high light intensity are used. Therefore, the most important points to consider when meeting our LED screen needs are:

• Company experience and reliability (in terms of producing the product it promises and after-sales support)
• The efficiency, pfc value, short circuit and current protection features of the power supplies to be used.
• Attention should be paid to the LED chip, LED case, driver integration and scan of the panel to be used.
• Attention should be paid to the refresh rate of LED panel driver integrated circuits.
• Attention should be paid to the wiring method and cable cross-sections.

Many brands of cards can be preferred as control systems for LED screens. Huidu (HD) cards are prominent in asynchronous products, while Nova and Linsn are prominent in synchronous products. All of these manufacturers have processor connection options.

While HD-C36C and HD-C16C stand out in Huidu cards, A3, A4, A5 and A6, which work integrated with the receiver, stand out in large-sized products, but the old series A601, A602 and A603 continue to be used in some Led Screen projects. Optionally, wifi, gps, 4g and sensors can be added to these Led Screen cards, the only difference of these Led Screen cards from other A series huidu Led Screen cards is that they do not have a processor feature and therefore require additional processors in live broadcasts.

Since the production of T802 as a sender in Linsn cards has ended, T921 series sender cards are used in LED screens to be made using Linsn, its most important feature is that it can read back the scan file of the RGB modules used in the LED screen, RV908 stands out as a receiver.

In Nova cards, MSD300, MSD600 Led Screen control cards are not preferred much in newly produced Led Screens due to asynchronous and processor featured Taurusu series Led Screen cards as senders. MRV332 and MRV336 come to the forefront as receivers.

Recently, due to the decrease in pixel size and increase in resolution in RGB Led modules and of course the decrease in prices compared to previous years, the production of Led Screens with lower pixels has increased, since these Led Screens are indoors and therefore do not need to take up too much space, magnetic systems have started to be preferred more, while in Turkey, Led Screen cases made with profiles are generally used in magnetic systems, self-magnet cases called mg cabinets are preferred more in China and Europe.

The RGB modules mentioned in the LED Screen information I explained above are more valid for LED Screens that can be made with RGB LED modules that we sell as Led Agency.

There are a considerable number of LED screen rental systems in the world. These systems are more commonly called Rental LED Screens. 

In the Rental Led Screens used in indoor rental, P3.91 P2.9 P2.6 P1.9 RGB Led Modules are mostly preferred. These Rental Led Screen modules are generally 250×250 mm in size, and 50×50 cm and 50×100 cm die cast aluminum rental led screen cases are used. Since these cases have a locking system and hanging bar mechanism, and also the cables are plug-in / power icon socket cables, the installation is very simple and very fast.

Finally, the LED screen systems used in oval, cylinder, semi-circle, angular transitions, wavy areas etc. produced with the recently popular Flexible LED Modules have started to be preferred a lot. As Led Agency, we mostly import P2.5 flexible modules and produce the LED screens needed with these modules. The most important feature of flexible modules, as understood from their name, is that they can take any shape we want horizontally due to their very flexible structure and are self-magnet. Flexible modules are produced as 1/32 or 1/64 scan.

When you are going to buy a Led Screen, do not make a decision and do not buy a Led Screen without seeing and calling Ledajans, which has been in the Led Screen sector for 21 years and is one of the leading companies in import, export and Led Screen solutions of its sector.
