How To Calculate LED Screen Resolution

LED screens are famous for immersive graphic presentations, from out-of-home digital advertising to the typical cinematic scenery. One of the key characteristics that enhances this unique feature is resolution. The resolution of an LED screen determines the quality and clarity of its pictures and movies.

In this article, you’ll learn different ways to compute your LED screen resolution. This will cover the step-by-step manual calculation, the online calculator, the types of LED displays, and factors influencing LED screen resolution. But before we fully delve in, here is further information about the topic.

What is LED Screen Resolution

What is LED Screen Resolution?

The overall amount of pixels in an LED display is referred to as its resolution. The word “pixel” is derived from the phrase “picture element,” which refers to the basic unit of a programmable graphic image on a display.

This indicates that a higher density of pixels within specific area results in more precise images and videos.

How To Calculate LED Screen Resolution

To derive the resolution of an LED screen, you can achieve that by multiplying the number of pixels in its horizontal and vertical dimensions. For example, if the breadth and height of a screen are 1920 and 1080 pixels, respectively, the resolution is 1920 x 1080, or 2 million pixels.

Furthermore, when estimating a display device’s resolution, it is critical to consider the impact of its “aspect ratio.” This corresponds to the width-to-length ratio of the screen. A screen with a width of 1920 pixels and a height of 1080 pixels has an aspect ratio of 16:9.

There are two primary methods for determining an LED screen’s resolution. These include the manual and online calculator methods. 

Manual Calculation

Here are the steps you should follow to calculate your LED screen resolution manually:

Step #1: Determine the screen’s Pixel Pitch

The Pixel pitch is the distance in millimeters (measured from the center) between two neighboring pixels on a screen. It is a key factor in determining the resolution of an LED panel.

Pixel pitch and resolution are inversely related. This means that when the pixel pitch decreases, the resolution, on the other hand, increases.

Step #2: Determine the screen size

The screen size is measured diagonally and in inches. You can achieve this by measuring from one corner to the opposite corner. Usually, any tape meter should help you arrive at a precise figure if appropriately used.

Step #3: Estimate the number of horizontal pixels

Here is a formula for calculating the number of pixels in the horizontal direction:

Number of pixels in the horizontal direction = Screen width (in inches) x 25.4 / Pixel pitch

Step #4: Calculate the number of vertical pixels

Similarly, here is the formula to determine the number of pixels in the vertical direction.

Number of pixels in the vertical direction = Screen height (in inches) x 25.4 / Pixel pitch

Step #5: Use the above values to solve the screen’s resolution

As mentioned earlier, LED screen resolution is the product of vertical and horizontal pixel numbers. The result represents the absolute number of pixels on your LED screen.

Screen resolution = No of horizontal pixels x No of vertical pixels

LED display per square resolution = 1/pixel pitch (units M) / pixel pitch (units M)

Online Calculator Method

Doing the LED screen resolution math can be challenging and time-consuming. A more accessible alternative is an online calculator.

There are many online calculators on the web at your disposal to aid your quest. Mostly, they require you to input the screen size and pixel pitch to get your LED screen’s resolution automatically.

Types of LED Screen Displays

Generally speaking, there are three main categories of LED screen resolution. Let’s uncover each in the following paragraphs.

Communication display

Sometimes, the aim is to use words to persuade the target audience. In this case, an average of 54 pixels tall will relay your message effectively. It’s common to commercial and mobile LEDs.

Graphic display

Here is a new screen classification suitable for image representations. Examples are creative LEDs. It’s often between 61 to 100 pixels in height.

Video display

When it comes to video showcases like in billboards, you need high resolution with over 100 pixels in length. For promotional effects, this is a jackpot for achieving incredibly vivid displays.

Common LED Screen Resolutions

There are several reference LED screen resolutions, each with its aspect ratio. Below are a few types you might be familiar with:

  • 1080p (1920 x 1080) – This is a Full High Definition (FHD) resolution with an aspect ratio of 16:9. You can see examples in televisions, computer monitors, and video projectors.
  • 4K (3840 x 2160) – This is another resolution known as Ultra HD. It also has an aspect ratio of 16:9. Manufacturers increasingly use it for high-end TVs and PC monitors.
  • 8K (7680 x 4320) – This also has an aspect ratio of 16:9. It is the highest resolution currently available and unique to top-line video production and digital exhibitions.

Factors Affecting LED Screen Resolution

A number of factors tend to affect the resolution of your LED screen. This is also to say that resolution is more than just the amount of pixels blended onto your display surface. Let’s discuss a few side-note contributors to an LED screen resolution.

  1. Pixel Pitch – Pixel pitch is used to calculate the distance between two consecutive pixels. It denotes how closely the pixels on display are packed.

A lower pixel pitch indicates that you will need a greater resolution to improve the quality of your screen display.

  1. Viewing Distance – The viewing distance is the recommended minimum length between an observer and the screen. 

When the viewer is too far away from the screen, individual pixels may become difficult to distinguish, resulting in a perceived decreased resolution. If the viewer gets too close to the screen, the pixels may grow excessively massive and seem blocky or pixelated, giving the impression of lesser quality.

The viewing distance should be optimized based on the screen resolution and size to obtain the optimal viewing experience. 

The ideal viewing distance varies according to the application and planned use of the LED panel. Generally, the greater the screen size and the better the resolution, the longer the ideal distance.

  1. Screen Size – The size of the screen also affects resolution. As a result, a larger display will need a higher resolution to maintain the normal image quality grade.
  2. Content – The content displayed on the screen can dictate the resolution required. High-resolution photos and videos will require a higher-resolution screen to display properly.

On a Final Note

While selecting an LED screen for installation, the resolution is an important thing to consider. In essence, it determines the quality of the graphic content your screen publicizes.

For a start, you should know how to arrive at a distinctive screen resolution. You can use the manual or online calculator method, as previously stated.

Also, remember that resolution is a composite of many role-playing components. Ensure they’re well thought over to find a suitable resolution for your LED display. For further inquiry, reach out to an expert now.
