One of the important factors that’s often overlooked when using an LED display is its LED viewing angles. No matter how wonderful your content is or how expensive your LED screen is, all of those won’t matter if people are not seeing them from the best angle. When people don’t have the best angle, they don’t get a good look at the screen or even the content. 

The LED display industry continues to be the frontrunner in the market, with a current global value of 6 billion US dollars. This means that it’s a booming industry you’d want to take part in. If you want to maximize your investments and make sure that you get your money back from buying a high-end LED display, the best thing to do is to optimize its use. And LED viewing angles will play a huge role in making sure you accomplish just that. 

The quality of the images or videos on your LED display can be affected by your distance from the screen. But it doesn’t mean that you will get a better picture if you are closer. There is a perfect distance from the screen that will give you the best image. A 36-inch QLED TV viewing angle will be different from a massive 90-inch LED wall viewing angle. This is why it’s crucial to understand how LED viewing angles work and how you can use them to your advantage. 

What Is an LED Viewing Angle?

When diving deep into this concept, the first thing to tackle is the LED viewing angle definition. An LED viewing angle or “half-power” angle is the ideal angle that’s formed when two observation directions are used on the same plane. It is the perfect angle where the LED screen can be seen clearly. 

LEDs produce light in a specific direction. This means that there is a specific range of angles where you will see the content on your LED screen in the highest visual quality. 

LED viewing angles are based on the cone shape pattern formed when the LED emits and distributes light, specifically the angle spanning from the cone’s top to its outer edge. This means that the viewing angle is the cone angle where the light meets. When it goes beyond that value, the light reduces its intensity. 

The standard angle is the one when you’re facing the LED screen. It is the position when the light is the brightest. As you change the angle of your sight, these are the changes that occur:

  • Reduced brightness
  • Color switching (due to color mixing of the lights)

Components of An LED Viewing Angle

LED Viewing Angles – Components

The LED viewing angles are comprised of two indicators, which are the horizontal and vertical viewing angles. These indicators help come up with a reference value that can pertain to the minimum and maximum angle for which the display can be clearly seen. You’ll always get two values for your LED viewing angles:

  • Top – Horizontal viewing angle
  • Bottom – Vertical viewing angle

Horizontal Viewing Angle

LED Viewing Angles – Horizontal Viewing Angle

The horizontal viewing angle points towards the vertical stand of the LED display. If you can imagine a vertical line that runs in the middle of the screen, that line provides the horizontal viewing angle. Simply put, it refers to the perspective looking at the left and right of the screen.  

Vertical Viewing Angle 

LED Viewing Angles – Vertical Viewing Angle

While the horizontal angle points to the left and right of the screen, the vertical viewing angle refers to the top and bottom. The change referenced on this angle is the color contrast, which reduces as the vertical viewing angle increases. 

Types of LED Viewing Angles

LED Viewing Angles

When considering LED viewing angles for your screen, look into all of the different types that can help. Here are some of the most common types of horizontal viewing angles you will see today. 

Narrow Viewing Angle

The narrow angle LED displays often typically fall between 10 to 30 degrees. The light spread on this angle is more concentrated and focused while the brightness is higher compared to a wide viewing angle. With lower degrees for the beam, the LED screens can be viewed at a farther distance. 

Medium Viewing Angle

This viewing angle falls between 30 and 60 degrees, guaranteed with a broader light spread but still with a focused and optimal direction. It is the famous choice for broadcast displays where the screens need to be seen from multiple angles. 

Wide Viewing Angle

The wide viewing angle is larger than the narrow and medium viewing angle. It falls between 60 and 120 degrees and has a much broader and diffused light spread. This is the ideal type of viewing angle for LED screens installed in viewing centers and small cinemas. 

Ultra Wide Viewing Angle

Among all of the LED viewing angles, the ultra-wide viewing angle offers the widest reach.  This refers to displays with the angles falling between 120 to 180 (if possible) degrees. It features the broadest light spread and is often applicable to gigantic LED screens. 

Why Do You Need to Know About LED Viewing Angles?

Learning about LED viewing angles is necessary to maximize the use of your LED screen and technically to use the display in the best way possible. This is only possible if you can match the LED viewing angle you choose with all the requirements and specifications you have for your LED display. The LED viewing angle you choose must cater to all the people who are part of your audience so that they can see clearly what’s displayed on the screen. 

Before you choose the specific LED viewing angle for your display, list down the specifications you have for your screen and the requirements of the event you’re planning. Some of the factors include the venue, content, and LED display application. Make sure to consider all the possible factors you want to prioritize when using the LED screen. 

Factors Affecting the LED Viewing Angle of Your Display

The LED viewing angle is influenced by several elements that you should also look into. Some of the elements that can affect the viewing angle of your screen enough that it can change the viewing experience are the following: 

  • LED Technology – SMD LED displays are capable of reducing brightness and contrast levels through different angles, which then offers a wider LED viewing angle. DIP LED displays, on the other hand, have a narrow angle for their LED viewing display. 
  • Screen Size – Bigger LED screens have wider viewing angles and farther viewing distances compared to smaller displays.
  • Pixel Pitch – An LED display with a smaller pixel pitch equates to a wider viewing angle while those screens with a larger pixel pitch have narrow LED viewing angles.
  • Brightness & Color Contrast – Brighter LED displays have a wider LED viewing angle since these screens are not affected by ambient light. On the other hand, the contrast of LED screens can decrease, depending on the viewing angle. This means that it is sensitive to possible changes in angle and so may appear sharper and more vivid from one angle but blurry from another angle. 
  • LED Viewing Distance – The LED viewing distance is directly proportional to the LED viewing angles. The higher that distance, the wider the angle is. 
  • Screen Coating – When the LED display has an anti-glare coating, you can enjoy a viewing experience with better visibility and less eye strain. A matte coating on the screen has better contrast and fewer cases of reflections. 
  • Screen Curvature – Obviously, curved LED displays have wider LED viewing angles compared to standard flat LED displays. It features better visibility with less impact from the ambient lighting. 

Improving an LED Display’s Viewing Angle

One thing you can do to ensure that you get the ideal LED viewing angle is to try it out using a piece of cardboard first. Cut out the cardboard with the same size as your LED screen and look into the different angles using the cardboard. If you want to improve the current setup and viewing angle of your LED display, here are some ways to do this:

  • Adjust the polarizer (Increase from 98% to 99.9%)
  • Choose the best polarizer to use
    • Transmissive polarizer – backlights
    • Reflective polarizer – ambient lighting
  • Use the highest-quality orientation layer
  • Use high-quality rubbing equipment, rubbing fiber, and polyimide
  • Try to test out different variations of display modes
  • Choose the panel type depending on your venue arrangement
    • Wide sitting arrangement – IPS panel or OLED screen
    • Far-back sitting arrangement – VA panel
  • Consult your LED display provider for the best LED viewing angles to consider

Choosing the Perfect Viewing Angle for Your Screen

There are several factors you can look into before randomly choosing among the LED viewing angles. Here are some of the elements worth looking into before making a choice.

  • LED display type – The size of the LED display is proportionate with its viewing angle. This means that large screens tend to have a wide LED viewing angle. 
  • Light-emitting diodes used – The type of LEDs used can influence the viewing angle of the display.
  • LED display usage and application – Your LED screen usage will affect the ideal viewing angle for the display. If you will be catering to many people, it is better to use a wide viewing angle.
  • LED display placement – Where you install your LED display must also be compatible with the size of the venue and the LED screen. 
  • The venue where the screen is installed – The bigger the venue and the larger the crowd you need to cater to, the wider the angle you will need. Here are some of the LED viewing angles you can use:
    • Indoor venue (90-120/60)
    • Outdoor venue (120-160/60-90)
    • Small office setup (60-90/60)
    • Large halls (90-160/90)
    • Massive conference rooms (160-180/90)
  • Quality of the LED display – High-quality LED screens often have wider viewing angles and fewer blind spots

LED Viewing Angle FAQs


What LED viewing angle should I choose?

Choosing the appropriate LED viewing angle will depend on multiple factors. The first thing you need to remember is that you need to accommodate all the people who need to see the screen. Just to be sure, check out all of the LED viewing angles you can use and match your needs with what the angles can offer.

Is it possible to improve the viewing angle of your LED display?

Improving the viewing angle of your LED display may be possible through proper placement but you won’t be able to achieve the optimal angle if you choose the wrong one. It may also help to use high-quality materials from the rubbing equipment, rubbing fiber, and orientation layer. The best thing to do is to use cardboard first with the same size as your LED screen and imagine the angles from there. 

Will the LED viewing angle change my screen’s brightness?

Yes, you will notice that there is a difference in the brightness of your LED display depending on the viewing angle you choose. The LED viewing angle is inversely proportionate with the screen’s brightness. This means that the lower the viewing angle you choose, the higher the brightness it shows. Make sure to bear that in mind when you decide on the LED viewing angle for your screens. 


Choosing among the LED viewing angles for your LED screen will require consideration of multiple factors. Take into account all of these elements, from the purpose of the LED screens to the venue where they will be installed and how massive the target audience is. Some things can be technical too and you can get overwhelmed by it. 

If you don’t know how to work on these LED viewing angles, it will be better to ask for the help of professionals. Ask your LED display provider for tips on what to use by providing your requirements and preferences.
