1. What is a Pixel Pitch Calculator?

Definition: This calculator determines the distance between pixels (pixel pitch) on LED screens based on the physical width and pixel width.

Purpose: It helps display manufacturers, installers, and AV professionals understand screen density and viewing distance requirements.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( P \) — Pixel pitch (millimeters)
• \( W \) — Physical width of the screen (millimeters)
• \( N \) — Number of pixels along the width

Explanation: The physical width is divided by the number of pixels to determine the center-to-center distance between pixels.

3. Importance of Pixel Pitch Calculation

Details: Pixel pitch affects image clarity and determines the optimal viewing distance. Smaller pitch means higher resolution but typically higher cost.

4. Using the Calculator

Tips: Enter the physical screen width in millimeters and the number of pixels along that width. Both values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What is a typical pixel pitch range?
A: Common LED screens range from 0.9mm (fine pitch) to 10mm (large outdoor displays).

Q2: How does pixel pitch affect viewing distance?
A: Smaller pitch allows closer viewing without seeing individual pixels. Minimum viewing distance ≈ 2000 × pitch (in mm).

Q3: Is pixel pitch the same as dot pitch?
A: Similar concept, but pixel pitch refers to LED displays while dot pitch was used for CRT monitors.

Q4: Why measure in millimeters?
A: The display industry standard is millimeters for pixel pitch measurements.

Q5: Does this work for curved displays?
A: For slightly curved screens, yes. For highly curved screens, more complex calculations are needed.
