Indoor led displays



Modern entertainment centers, supermarkets, cafes and restaurants are full of advertising LED panels. This type of supply of goods is the most effective, and therefore is very popular among entrepreneurs.

Even visually visible tangible difference in appearance at the external screens and those used for premises. Due to the fact that the room does not need to protect the screen from external environmental influences, they are much lighter and thinner than the external ones. This facilitates their installation and maintenance.

The number of LEDs in one pixel of the internal screen is no longer 2, as in the external, but three. Due to the increased density of their location, it is possible to achieve a decrease in viewing distance. For a small cafe or restaurant, this is just a godsend.

Visitors’ eyes will not get tired quickly from viewing information from such an LED screen.

Another important point is that the brightness of LED screens for interior does not exceed 2000 cd / sq m. At the same time, the viewing angle is 160 degrees. Due to this, the owner of the area can save on payment of the bill for electricity in two or even three times!

The purity of the image is achieved by the SMD LED lamps, which have conquered the world with their color capabilities.

Characteristics of LED and SMD martits
The most common in our country are LED and SMD screens.

In the LED matrix, all components are connected together and represent a single element. It includes a control system, diodes and switches. All these parts are interconnected by a compound that is a black resin. Such screens are very easy to install and serve for a long time.

As for the SMD panels, this is the most modern devices. They consist of electro radio elements. Such panels are assembled by automatic machines, therefore their quality is much higher than LED screens.

Specifications of indoor screens
Among the general parameters for each screen manufacturer are the following:

quick installation;
no flicker;
high brightness and stability;
quick installation;
ease of maintenance and care.

LED screen design
The screen of the LED screen is combined. It is mounted very easily from LED modules. Thanks to this, individual modules can be quickly and simply replaced if necessary.

As the basis of each module, the manufacturers selected a frame made of aluminum. After bonding, all modules represent a single sturdy construction. The assembled screen can, if necessary, be placed in any enclosure made by a local company.

Screen brightness
In LED screens that are designed for indoor use, bulbs most often used are from 30 to 150 millicandels. High brightness of the screen will be provided by super bright LEDs. At the same time, the brightness of the panel can vary from 7000 to 18000 cd / sq m. Do not forget that the LEDs need to be adjusted. This achieves the perfect screen glow.

Screen resolution
What could be more important for the LED panel, if not its resolution? It depends only on the number of pixels that are placed on a certain area of ​​the screen. A high-quality image can only be created by a large number of LEDs per square meter.

There are certain standards for screen resolutions: 160/120, 320/240, etc. It is clear that the higher the resolution, the higher the image quality of the LED panel.

But manufacturers went further and found a way to increase the optical resolution, without resorting to an increase in pixel density. The new technology is called “virtual pixel”. Its essence lies in the ability to control the glow of individual LEDs in the module itself.

Signal processing
Modern control systems for LED screens make it possible to receive signals of any format.

Most of the LED panels that are used in different countries of the world can only reproduce graphics or animation. But, there is a more expensive version of screens that can play images from video cameras, TVs, video players.

Automatic adjustment of display parameters
Each LED display has a control system. It allows you to automatically change the brightness of the screen depending on changes in the ambient light. Since the light output of the lamps decreases during the daytime, they can last longer, and a considerable amount of money can be saved on electricity.

Viewing angles
The viewing angle of LED panels is 140 degrees horizontally and 60 degrees vertically. With smaller viewing angles, the image will lose about 50 percent brightness.

Observation range
The observation range of LED displays is determined by the number of pixels and their density per square meter. Different models of screens have their own parameters. The range varies from 5 to 22 meters. Of course, do not forget about the size of the screen itself in this matter
