Factors Affecting The Viewing Angle Of Full Color LED Display

Now we all know that whether it's a TV,a computer screen,or a LED screen,they all have their viewing angles.Similarly,there is also a viewing angle in the LED display field.What is the viewing angle of full color LED display?What is the viewing angle associated with?

First,it’s the definition of the viewing angle of full color LED display screen.

Viewing angle is the angle that users can clearly observe everything on the screen from different angles.The viewing angle can also be understood as the ability to see the screen clearly at the maximum angle or the minimum angle.The viewing angle is only a reference,and the viewing angle of LED full color display includes both horizontal indicator and vertical indicator.For example,LCF’s rental LED display,the technical parameters are described in this way(visual angle:140 degrees/140 degrees).It means that the largest viewing angle is 140°,both the vertical and horizontal visual angle are 140°,when it's over 140 degrees,it may lead to undesirable watching-effect and blind spots.

The horizontal viewing angle is based on the normal line of the full-color LED display(that is,the vertical imaginary line in the center of the LED display).when the display image is still visible at the angle of the left side of the normal line or the right side of the normal line,then the angle range is the viewing angle of the LED full color display.Similarly,if the horizontal normal is as the standard,the visual angle of the upper and lower angles is called vertical viewing angle.In general,the viewing angle is based on the contrast change as a reference standard.When the viewing angle increases,the contrast of the displayed image seen at this location will decrease,and when the angle increases to a certain degree,the contrast down to 10:1,this is the full color LED display’s maximum viewing angle.

Second,there are factors affecting the viewing angle of full color LED display.

Generally speaking,the larger the full color LED screen can be seen by the audience,the larger the viewing angle is.But the size of the viewing angle is mainly determined by the tube packing method,so it must be considered carefully when packaging the tube.In addition,the visual angle is closely related to the visual angle and distance.But now most LED display manufacturers are unified in angle.The cost will be high if you have to customize the angle according to the circumstances.To the same chip,the greater the angle,the lower the full color LED’s brightness.

How Should The Outdoor LED Display Be Strengthened And Maintained

As an outstanding representative of LED outdoor applications, outdoor LED display is suitable for many fields of life because of its convenient maintenance, energy saving, wind resistance, pressure resistance, stable and reliable operation. As we all know, there are many kinds of common display screens, of which there are countless good ones, but no matter which one, the good color expression is a beautiful sight in the bustling city.

As anyone in the professional LED industry knows, it is essential to have installation and debugging process for the outdoor LED display to run well. So for technical construction personnel, know good outdoor building, maintenance, advertising screen skill will be able to better promote the business advertising and information dissemination. It also must be known to a technical construction worker. In fact, the installation of outdoor LED display is generally divided into four parts: field investigation, equipment construction, product installation, and product debugging.

For these outdoor LED display screens, it is important to distinguish the outdoor wall advertising screen and the hanging advertisement screen. In the actual installation of these screens, we should use the crane and the hoist to carry out the sectional hoisting according to the height of the distance, and ensure that the following and above staff can cooperate with each other. In order to make the LED screens in the upper air have a better installation and use process. In the process of building, safety and fine operation must meet the first requirement.

Of course, as a senior high quality LED display construction personnel, only know installation is not enough. Usually, the main body of the outdoor LED display support structure is mainly steel materials, because in the open air environment, by the influence of temperature, humidity, harmful substances and other factors, it is extremely easy to be oxidized and cause corrosion, or even serious corrosion, so the ability of steel components to resist loading capacity is greatly reduced. So how to better maintain the outdoor LED display has become our essential homework. So how to better maintain and extend the life of the display in the end?

The concrete is directly poured under the underpinning of a bored foundation, and a static column, a driven pile and a filling pile are arranged on the lower or the two sides of the billboard foundation to reinforce the foundation.The chemical slurry is injected into the foundation evenly, and the original loose soil or fracture cementation is solidified by these slurry, so as to improve the foundation bearing capacity and waterproof anti-seepage. By setting concrete enclosures or reinforced concrete enclosures, the floor area at the bottom of the outdoor LED display screen is increased, and uneven settlement of the foundation due to the small base area of the billboard and the insufficient carrying capacity is changed.Reasonable maintenance of outdoor LED display method is essential, because in the future life it can be very good to help the majority of users.
