LED Screen Types and Pixel Pitch Explained: What Matters for Mobile Advertising in Egypt
If you have researched LED screens, you have seen specs like P2.5, P3, P4, brightness in nits, and indoor vs outdoor. These matter a lot if you are buying a screen, but if your goal is advertising on a moving screen, only a few of them actually affect your campaign. This guide explains LED screen types and pixel pitch in plain language, then shows which specs matter when the screen is on a vehicle driving the street, not hanging on a wall.
What Is Pixel Pitch (P2.5, P3, P4)?
Pixel pitch is the distance in millimeters between the centers of two neighboring LEDs. A lower number (P2.5) means pixels are closer together, so the image is sharper up close. A higher number (P4, P6, P10) means pixels are farther apart, which is fine because the screen is viewed from farther away. The right pitch depends on viewing distance, not on "bigger is better."
| Pixel pitch | Pixels | Best viewing distance | Typical use |
|---|---|---|---|
| P2.5 | Very close together | Close up, a few meters | Indoor, lobbies, close screens |
| P3 to P4 | Medium | Several meters | Indoor-outdoor, stages, close outdoor |
| P5 to P10 | Farther apart | From across a street | Outdoor billboards and mobile screens |
LED Screen Types in Short
- Indoor LED: lower pitch, lower brightness, for close indoor viewing.
- Outdoor LED: higher brightness and weatherproofing, for daylight and distance.
- Transparent LED: see-through, for glass storefronts.
- Mobile LED: an outdoor-grade screen built onto a vehicle for advertising on the move.
Which Specs Actually Matter for Mobile Advertising
When the screen is advertising from a moving vehicle, the audience is across a wide street and in daylight, so the priorities change:
- Brightness (nits): the most important spec outdoors. The screen must stay readable in full sun.
- Outdoor-grade and weatherproof: it has to survive sun, dust, and the road.
- Size: a large screen like 20 m² reads clearly from across a road.
- Pixel pitch: matters less than indoors, because the viewing distance is long. A mid-to-high pitch is correct for street viewing, and chasing an ultra-low pitch adds cost for sharpness no one at street distance can see.
In other words, for mobile advertising you want a big, bright, outdoor-grade screen, not the lowest possible pixel pitch.

The vehicle already carries 20 m² of high-brightness, outdoor-grade LED, correctly specced for street viewing in Egyptian daylight, on air up to 10 hours a day, with live GPS tracking, live streaming, and route reports, priced in EGP. You bring the creative; the screen is already built for the job.
Frequently Asked Questions
What does pixel pitch (P2.5, P3, P4) mean?Pixel pitch is the distance in millimeters between neighboring LEDs. A lower number means sharper images up close; a higher number is fine for screens viewed from farther away, like outdoor and mobile screens.
Which pixel pitch is best for outdoor and mobile advertising?A mid-to-high pitch is correct, because the audience is across a street. Brightness and outdoor-grade build matter far more than an ultra-low pitch, which adds cost for sharpness no one can see at that distance.
What is the most important spec for a mobile LED ad screen?Brightness. The screen must stay readable in full daylight. Outdoor-grade weatherproofing and a large size come next; pixel pitch matters less at street viewing distance.
What is the difference between indoor and outdoor LED screens?Indoor screens use a lower pitch and lower brightness for close viewing. Outdoor screens are much brighter and weatherproof, built for daylight and distance, which is what mobile advertising needs.
Do I need to understand specs to advertise on a mobile screen?No. With Road Reach the screen is already specced for street advertising, so you only supply the creative and choose your routes and days.
