What is Pixel Size & Pixel Pitch?

With LED walls, each individual LED is a pixel. The pixel pitch number indicates the distance between LEDs on the wall in millimeters, as well as the minimum viewing distance in meters. The optimal viewing distance is typically 2-3 times the pixel pitch number in meters. Pixel pitch affects both viewing distance and visual performance of LED displays.

The lower the pixel pitch, the closer together the LEDs are on your display, and the closer your viewing distance would be for the video board. For example, a fine or narrow pixel pitch of 2 would allow viewing from just two meters away, whereas a pixel pitch of 10 would require at least a distance of 10 meters to experience optimal detail.

Why is pixel pitch important?

It’s important because it directly correlates to your display resolution and optimal viewing distance. The smaller the number, the more pixels used to make up the image on your display, thus improving the resolution and optimal viewing distance. What does this mean in plain terms? The lower the pixel pitch, the closer a viewer can stand to your display and still have a great resolution.

So, wouldn’t a smaller pixel pitch be better all of the time? It does help your picture, but at a cost. By having a smaller pixel pitch, you increase the number of LED clusters for your display. A NanoLumens 114″ display with a 4mm pixel pitch uses 247,760 pixels, where as a 6mm LED display of the same size uses 96,000. The more LED clusters in your display, the lower the pixel pitch and the higher your expense. You can cut your costs and still have a fantastic display by going with a larger pitch if your audience isn’t too close to your screen. If your display is in a space where your target audience will be closer to the display screen, such as in a retail environment, a 4mm  is probably better suited to your needs. If you are hanging your display higher and in turn further from your target, for a project such as airport signage, a 5mm or 6mm pixel pitch display may be best for you.

 

 How to Choose the Best Pixel Pitch?

 

There are 5 main factors to consider when choosing the proper pixel pitch for an LED video wall.

 

 

 

1. Board size. If you know the desired size for your LED board, you can backtrack from this measurement to an optimal pixel pitch. For a rectangular board with a shorter vertical dimension than horizontal dimension, a general rule of thumb to achieve a standard resolution of 1920 x 1080 is to divide your horizontal dimension (in feet) by 6.3 to get your pixel pitch (in mm). So for example, a 25.2 x 14.2 foot board is best served by a 4mm pixel pitch, as 25.2 / 6.3 = 4.

 

 

 

2. LED screen optimal viewing distance. If you know the desired viewing distance for your LED board - for example, the distance to a billboard from a highway - you can simply divide your desired viewing distance (in feet) by 8 to get your optimal pixel pitch (in mm). So for example, a 32 foot viewing distance would correspond to a 4mm pixel pitch, as 32 / 8 = 4.

 

 

 

3. Indoor or outdoor. Outdoor screens will generally be viewed from a larger average viewing distance, so you can use a larger pixel pitch for a more cost-effective option without sacrificing customer experience. By contrast, indoor screens will generally be viewed from across a hallway or lounge at the furthest, so a smaller pixel pitch is more important in these applications.

4. LED screen resolution. As discussed previously, if you need a higher resolution, you will need a smaller pixel pitch. Similarly, if you are alright with a lower resolution, you can use a larger pixel pitch.

 

 

 

5. Your budget. It is important to consider what pixel pitch is optimal for your application given the resources that you have at hand. A superior pixel pitch that is outside of your price range is not a useful figure to know, so always consider your budget when choosing a pixel pitch.
