How to Measure the Pixel Pitch of a Small Pixel Pitch LED Display

If you're seeking the best digital signage for your brand, then you need to pay attention to the pixel pitch of the LED display you choose. In this way, you can choose a small pixel pitch LED display that can provide your brand the most effective visual presentation.

The visual quality of an LED display screen has greatly improved as a result of the proximity of the pixels. In addition to reducing the required viewing distance, technical difficulties associated with insufficient grayscale and excessive brightness have been addressed.

But, how do you measure the pixel pitch of an LED display to know which one best suits your brand's presentation? Let's find out.

What is a Pixel Pitch?

Simply put, pixel pitch is the space between individual pixels. The term "pixel pitch" refers to the distance between the centers of two consecutive pixels.

Commonly, this is expressed in millimeters. LEDs are packed in tighter when the pixel pitch is smaller, giving small pixel pitch LED display a high-resolution quality.

A high resolution on an LED display is indicated by a narrow pixel pitch, which allows for a comfortable viewing distance. When it's low, fewer pixels are used to create the display's final image. Hence, the screen's optimal viewing distance and resolution are enhanced.

Consequently, LEDs with a narrow pixel pitch produce a higher quality image but come at a hefty price.

How Do You Measure Pixel Pitch?

Accurately measuring pixel pitch is key to selecting the best LED display. Here’s how you can do it:

1. Identify the Pixel Configuration

• SMD (Surface-Mount Device): In SMD LED displays, the RGB diodes are closely packed together. The pixel pitch is calculated from the center of each RGB LED.

• Discrete LED: Each individual RGB component is physically separated, so pixel pitch is calculated similarly but takes into account the individual LED positions.

2. Measure Distance Between Pixels

Measure the distance between the centers of two adjacent pixels, both horizontally and vertically. This gives you the horizontal and vertical pixel pitch, which should be the same for most LED displays.

3. Calculate Pixel Pitch for Flat vs. Curved Screens

On curved displays, pixel pitch may vary slightly due to the curvature of the screen. For accurate measurement, calculate from the screen's flat surface, as this is the standard for pixel pitch measurement.

4. Use Proper Tools for Accuracy

To ensure precision, use a high-quality measuring tool such as a laser caliper or pixel pitch measurement device. These tools allow for accurate measurements of pixel distance.

For instance, let's use the 3 square meters LED display screen as a typical example to calculate pixel pitch. The pixel pitch for a 3 square meters LED display is equivalent to 30,000 pixels when multiplied by the pixel density of 10,000 pixels per square meter. Hence, by multiplying the surface by 10mm, you may obtain the optimal amount of pixels for recording video and taking still images.

Why Pixel Pitch Matters in LED Displays

The smaller the pixel pitch, the better the resolution and visual clarity. Small-pitch LED displays provide stunning image quality even at close viewing distances, which is crucial for digital signage and indoor displays. However, smaller pixel pitches come at a higher cost, so it's essential to balance quality and budget.

Common Pixel Pitch Ranges and Their Applications

• Indoor Displays: Pixel pitches between 1mm to 3mm are typically used for indoor settings like conference rooms, control rooms, and retail spaces.

• Outdoor Displays: Pixel pitches of 5mm or higher are often used for large-scale outdoor displays such as billboards and stadiums.
