Are you familiar with Pixel Pitch? When learning about outdoor led digital displays, you will come across industry terms that you're not familiar with. But don't let this bother you. Knowing and understanding these basic display technology terms is vital in making a decision for your business.
Since you're purchasing LED signage, you'll often encounter options that include different "pixel pitches." When it comes to LED signage, finding the right Pixel Pitch is the key to the success of your display. It determines the clarity, effectiveness, and cost of an LED sign.
What exactly is Pixel Pitch?
Pixel Pitch basically defines the distance between pixels and describes the density of the LED pixels on the message system. It is also known as "dot pitch" or "pitch," usually expressed in millimeters. It is measured from the center of one pixel to the center of an adjacent pixel.
It is fundamental factor of a screen's viewing distance as it defines the performance of the LED screen.
Pixel Pitch determines LEDs density (usually known as resolution). When reducing the pitch, the resolution increases exponentially.
Take note: the lower the Pixel Pitch, the more pixels can be fitted together on a display.
How does Pixel Pitch affect LED displays?
Pixel pitch affects viewability when viewing large displays up close.
- The lower the pixel pitch, the higher the screen resolution.
- For example, a 7.8mm screen has more resolution compared to a 10mm or 20mm screen.
- The more pixels, the higher resolution the display will be when viewed close up.
This is the reason why big LED displays look great from a distance but get uncomfortable to view when you get near it.
- The bigger the pitch, the longer the minimum viewing distance.
Since the total number of pixels present on the screen is lower, the cost per area is lower too.
- The smaller is the pitch, the shorter is the minimum viewing distance
And because the total number of pixels present on the screen is higher, the cost per area is higher too.
What is a typical Pixel Pitch measurement?
- Indoor LED displays ranges from 4mm to 20mm.
- For viewers closer to the screen, such as retail store or office environment, a 4mm display works best.
- For intermediate viewing distances such as shop windows, an 11mm pitch is a good display.
- If an indoor led screen will be placed higher than the viewer, such as airport signage, use a 5mm or 6mm display.
- Most commercial outdoor LED signs stay in the 16mm to 25mm range.
- Smaller signs typically use 16mm and lower pitches to fit more pixels into the smaller area while maintaining quality image.
- Large digital billboards commonly use 25mm to 32mm pitches, while smaller ones (which are closer to viewers) uses 20mm to 16mm.
