The viewing angle of your led screen ensures that images look great even when you’re watching them from the side. Subsequently, audiences can enjoy a vibrant and clear image without the need to stand directly in front of the screen. In this post, you will learn more about led display viewing angles and their impact on the viewing experience.

What is LED Display Viewing Angle?

The viewing angle in LED displays is the maximum angle at which we can visualize clear images without perceptible quality degradation. Simply, it’s the range within which viewers can observe the screen and discern images without color fading, distortion, or reduced brightness.

Typically, LED display viewing angles include both vertical and horizontal aspects. A general rule of thumb is that the larger your LED screen’s viewing angle, the greater the range it offers for watching. However, a larger viewing angle comes with a trade-off in screen brightness.

Also, varying scenarios call for different angle requirements. For instance, the viewing angle for indoor LED displays should be more than 120°, while outdoor applications require a viewing angle of more than 140°.

So, an LED display with a parameter value of 140°/120° means it offers a horizontal viewing angle of 140° and a vertical angle of 120°.

How Does LED Display Viewing Angle Work?

The LED viewing angles TV comprises horizontal and vertical indicators. The indicators provide a reference value for images’ maximum and minimum viewing angles.

Horizontal viewing angle of LED display

The horizontal viewing angle is the imaginary line at the center of a full-color LED display.  The human eye can see images clearly at a certain angle to the right or left side of the vertical line.

Vertical viewing angle of LED display

While the horizontal angle refers to the right or left points of the screen, the vertical viewing angle points to the top and bottom. Increasing the vertical viewing angle reduces this change, known as color contrast

Factors Impacting LED Display Viewing Angle

The viewing angle of your LED display will depend on several factors, including:

Manufacturing Variations

You won’t just stumble on a good, reliable LED display screen. The quality and precision of the manufacturing process count and will determine the overall viewing angle. 

Not known to many, different manufacturing variations can alter the optimal viewing angle even with two screens with a similar LED mode. Therefore, each manufacturer will specify the TV’s viewing angle, which varies among different models.

LED Size

Overall, larger LED screens usually offer a broader module viewing angle compared to smaller ones of similar specifications. The larger LEDs feature a broader lens surface, allowing for a broader dispersion of light. Such a dispersion translates to a wider viewing angle.

Material Properties

The refractive index of the materials utilized in the lens or optics will also determine the viewing angle of the LED display screen. Furthermore, different materials refract or scatter light differently, thus affecting the display.

Optics

When selecting an LED screen, consider additional optical elements, such as lenses, diffusers, and reflectors. These elements shape the light beam and control how it spreads. Thus, it affects the general viewing angle. 

In addition, these secondary optics allow for more custom experiences that could help you enhance your LED display TV viewing angles. 

Reflector Design

When you observe the LED TV viewing angle chart, you’ll notice that some LED screens feature a reflector. This reflector controls and directs the emitted light. On the other hand, the optical part regulates the outgoing luminous flux. Also, the reflector alters the light beam from the LED source, which diffuses or directs light patterns.

LED Chip Design

Like the escalator, the internal LED chip design and physical structure will impact your screen’s viewing angle. Manufacturers go to great lengths to accurately arrange and place the LEDs within the chip, influencing light emission and dispersal for enhanced viewing experiences.

Whereas the packaging technology deployed in the LED chips determines the viewing angle, the packaging methods, such as SMD, DIP, and COB, scatter light differently. As such, they affect the LED display viewing angle. 

Generally, COB technology offers the best solution for applications that require wider viewing angles. On the other hand, SMD technology is the go-to option for applications that require a moderate viewing angle.

Encapsulation Design

Encapsulation, commonly known as lens design, is vital in defining the optimal viewing angle. This metric refers to the design of the LED chips and offers varying viewing angles, including flat, diffused, or dome-shaped.

Therefore, when you buy an LED display, consider the lens design’s size, shape, and curvature. These are critical factors that regulate the dispersal of light from the LED. 

Types of LED Display Viewing Angle

Here are the most  common viewing angles that LED screens offer:

Ultra-Wide Viewing Angle

The Ultra-wide viewing angle offers the broadest reach among all LED displays. This display offers a viewing angle between 120 and 180 degrees. With its broad light dispersion, it is applicable in giant LED screens and displays. Additionally, it works in excellent instances requiring uniform illumination.

Wide Viewing Angle

The wide viewing angle displays follow closely with a range of 60 to 120 degrees and a broad light dispersion. The feature makes them suitable for centers and small cinema applications.

Medium Viewing Angle

The medium viewing offers a viewing angle of between 30 ° to 60°. It is a broad light display that guarantees a focused viewing. Also, this type of screen is the best for broadcast display since it allows thousands of people to follow the proceedings from multiple angles. 

Narrow Viewing Angle

The angle falls between 10 and 30 degrees with the concentrated and focused light to allow for a narrow viewing angle. The focus makes the narrow viewing angle an ideal choice where highlighting the focal points is required.

The Importance of LED Display Viewing Angle

The LED display viewing angle is essential to determine the screen’s suitability for a specific application. A wider viewing angle ensures that everyone enjoys the viewing despite the sitting position.  Therefore, LED display viewing angles are important in the following aspects: 

Optimal Performance

Choosing the right viewing angle ensures the LED screen is crystal clear and maintains quality color and consistent brightness.  The optimization guarantees high-quality images that maximize the viewing experience. 

Application Requirements

Whether digital signage or billboards, you must consider the viewing angle metrics for every application. An increased viewing angle maximizes visibility regardless of where one is seated. On the other hand, a narrowed viewing angle is better where one requires focused illumination.

Design Flexibility

Since some applications for LED lighting vary depending on the lighting effect, different LED viewing angles help achieve flexibility. 

Energy Efficiency

LEDs with optimal viewing angles are energy efficient because they direct light to the desired areas, reducing power consumption. Also, a wider viewing angle reduces the need for multiple displays when hosting larger audiences.

Visual Comfort

A wider viewing angle allows for consistent brightness and color, which increases viewing comfort. Besides, it eliminates the shifting of colors and glare. Such an angle enhances the viewing experience.

Beam Control

Beam control is essential in lighting applications. It re-directs light in the desired areas and optimizes performance. 

Light Distribution

The dispersion of light is dependent on the viewing angle. Consequently, an appropriate viewing angle is required to distribute light evenly across the targeted area. 

How to Measure LED Display Viewing Angle

Considering the importance of display viewing angle, it is prudent to consider how to measure the angle. 

Radiant Intensity Measurements

Here, you’ll use a radiometer to measure the LED’s intensity. The measurements you get help determine the correct viewing angle. 

Photometric Measurements

A photometer measures the intensity of light the LED emits at different angles. Placing the tool in strategic angles will help you measure the intensity, hence determine the optimal viewing angles

Integrating Sphere

This is a sphere that features a reflective coating. The tool comes in handy when measuring the LED display’s luminous flux. Typically, it helps determine the viewing angle. 

Imaging Photometer

The tool captures light intensity at different angles to analyze and determine viewing accurately.

Goniophotometer

The equipment measures the distribution of light coming from the LED source. As such, it determines the viewing angles accurately.

Optimizing LED Display Viewing Angle
