Optimizing your led viewing angle

LED display screens now play a very important role in our life.

They gave us clear and colorful images for advertising, and they provide amazing visuals and help to make the stages to be attractive and vivid.

To make sure the LED screen panel to contribute the most excellent viewing experience, you must choose the good viewing angle.

In this article, we will tell you how the viewing angle works and how best to use it.

What is Viewing Angle? Why it is important for the LED screens?

The viewing angle means the highest angle at which a Light Emitting Diode(LED) screen can be viewed while still optimizing for features like color quality and brightness.

From its simplest explanation, LEDs are emitting lights in the direct way.

They do not like LCD screens, the viewing angle of LCD screens are more flexible.

And LED screens emit light in a specific direction.

With the viewing angle, you’re looking at the extent of this emitted light cone, within which viewers are able to see light clearly and at topmost quality.

Let us make it clear and take some examples. When an LED emits light, it creates a cone-shaped pattern that essentially distributes that light.

The top of that cone represents the LED chip itself, while its base represents the outermost edge of light distribution.

The LED viewing angle essentially is determined by the angular span between the top of the cone and the outer edge, where the light intensity meets the specific viewing area.

For example, when you look into the specification of the LED screens, and it shows the viewing angle is 60- degree.

It means that the light intensity meets the specified area within that 60-degree cone angle.

So, within the 60-degree angle, you will see a very beautiful and lively image of the LED screen contents.

Beyond this angle, the color of the LED screen will be very dark, as there is a significant drop in light intensity, which will in turn reduce the visibility of the emitted light,

With the viewing angle, you see an effect on the perception of the LED’s light – especially when viewed from different angles.

When you face the LED screen panel directly, you see light appearing the bright aera.

But, as the angle deviates from that on-axis position, the perceived brightness drops, and you could also see a switch in color due to changes in the emitted light’s color mixing.

Typically, the LED screen viewing angle is measured in degrees – and, it represents the range of angles within which you can continue to view the emitted light in LED screens with the topmost visual specifications.

What features that will influence the viewing angle?

After we know what is the viewing angle, we will know there are some features that have a big influence of the viewing angle.

LED Chip Design:

The internal design and physical structure of your LED chip will influence the viewing angle.

In China, the manufacturers invest a lot and do many studies to place and arrange LED diodes within the chip, all these are ensure that for the emission of light is stable and its dispersion for your viewing pleasure.

Material Properties:

The refractive index and optical properties of the materials used in the encapsulation, lens, or optics can additionally influence the viewing angle.

Keep in mind that there are different materials, all of which can scatter or refract light differently and affect the LED spreading.

LED Size:

As we all know that a larger LED will come with a broader LED module viewing angle compared to a smaller LED.

This is primarily because larger LEDS tend to have bigger lens surfaces, thus making it easier for light to disperse across a broader angle.

Manufacturing procedures:

The viewing angle is usually specified by the LED manufacturers.

We recommend that you need to study and consider the right specifications and choose LEDs that have the best viewing angles and characteristics, so that your LED video wall project will done very successfully and beautiful.

How many types of the viewing angles?

LED viewing angles are very important for making the solutions of the LED screen project as the suitable viewing angle will give the good video quality and the balanced colors.

Let us have a look at the viewing angle options:

Narrow Viewing Angle:

A LED with a narrow viewing angle will most likely range from 10 to 30 degrees.

These LEDs emit a concentrated light beam, allowing them to work for applications where focused lighting and viewing is required.

With their focus on specific actions, narrow LED viewing angles are perfect when highlighting individual focal points.

Medium Viewing Angle:

When you move to the medium viewing angle LED, you’re focusing more on viewing angles that range between 30 and 60 degrees.

These LEDs generally provide a broader light spread compared to their narrow viewing angle LED screen options.

Medium viewing angle LEDs have become especially popular in retail display screens, where companies hope to broadcast to broad ranges of people coming from multiple directions.

Wide Viewing Angle:

As you’d expect, there is also a wide viewing angle LED.

When a LED comes with a wide viewing angle, you’re typically looking in the range of 60 to 120 degrees.

Light dispersion for these screens is much broader, making them perfect for scenarios where you need to cover a much wider area – such as small cinemas and viewing centers.

Ultra-Wide Viewing Angle:

With ultra-wide LED viewing angles, you’re moving above 120 degrees – reaching possible 180 degrees.

So, if you’re asking, “What is 160 degree view?” you’re most likely looking at the ultra-wide category.

With these LEDs, light dispersion is the broadest.

The screens are used generally in applications where you need uniform illumination, and they’re among the biggest screens we see today.

How To Choose The Right LED Viewing Angle

If our LED screen projects are in right viewing angle, we will see our LED screen will present its most perfect way. But to choose the right viewing angle, we need to consider several factors.

Installation site conditions:

One of the first and most important things for you will be to check the installation site conditions.

We should consider the surrounding environment and any possible obstacles.

If the LED screen is curved and the sun will direct to the screen during the day, we need to consider the brightness uniformity and what is the viewing angle will be to make the screen to look in the perfect way.

Viewing angles and distance from the viewers

To get the best LED screen viewing angle, you also need to check the precise location and physical layout, as well as the distance between the LED screen and the viewers.

You also need to check if people will view the screen from different directions. Those all decide what is the best viewing angle of your LED screen projects.

The professional advice from the LED engineer

If you are not sure about the what is the appropriate viewing angle for your LED screen projects, you can check with professional LED screen manufacturers.

When making the solution of LED display screen projects, one of the most important elements always keep in mind is the optimization of the viewing angles. With the right LED viewing angle, we can get the best image quality and light dispersion, while also optimizing energy.
