You install a great LED screen for your event. It shines, it catches the eye. But half your audience is off to the side… and sees almost nothing. The image is washed out, the colours have gone. Your message? Lost. That's exactly what the viewing angle prevents. And it's simpler to understand than you think.
At Proxiled, we've been installing LED screens since 2009 — at trade shows, in shop windows, by the roadside, at events. And one of the mistakes we see most often? Choosing a screen without considering the viewing angle. The result: an under-used investment. In this guide, we explain everything so you don't fall into that trap.
What exactly is the viewing angle?
Imagine a cone of light coming out of your screen. At the centre of the cone, the image is perfect: vivid colours, readable text, sharp contrast. The further you move to the side, the weaker the image becomes. At some point, you can't see anything usable.
The viewing angle is the zone within which your screen stays readable. It's measured in degrees, horizontally and vertically. For example, a 160° horizontal angle means the screen remains visible across a 160° arc in front of it.
In short: the wider the angle, the more people see your message — even those who aren't standing right in front. A quality LED screen typically offers 140-160° horizontally and 120-140° vertically.
Why does this concern you directly?
Think of these real-life situations where the viewing angle makes all the difference:
🎪 Your trade show stand
Visitors walk down the aisle. They're not directly in front. If the screen is only visible head-on, you miss 7 out of 10 visitors.
Your shop window
Pedestrians approach from the left or right. A good angle = you catch them as soon as they approach, not only when they're right in front.
🛣️ Your roadside screen
Drivers approach at an angle. A screen with a narrow angle = message visible for only 1-2 seconds. A wide angle = 5-8 seconds of visibility.
Your conference room
Attendees sitting at the sides also need to read the slides. A narrow angle = the side seats are useless.
Comparison table: viewing angles by technology
| Technology | Horizontal angle | Vertical angle | Verdict |
|---|---|---|---|
| SMD LED screen | 140-160° | 120-140° | ✅ Excellent |
| DIP LED screen (outdoor) | 110-140° | 60-90° | Good (horizontal) |
| Standard LCD/TV screen | 170-178° | 170-178° | ✅ Very good |
| Projector | Variable | Variable | ❌ Poor |
| Inflatable screen | 100-120° | 80-100° | ❌ Limited |
Important note: an LCD/TV has an excellent viewing angle on paper, but its limited brightness (300-1000 nits) makes it invisible outdoors or in a very brightly lit environment. The LED screen makes up for a slightly narrower angle with 5 to 10 times more brightness.
SMD vs DIP: what impact on the angle?
There are two main families of LEDs:
SMD (Surface Mounted Device)
Surface-mounted LEDs. Even light distribution in all directions. Wide angle (140-160°). This is the current standard for indoor use and increasingly for outdoor use.
DIP (Dual In-line Package)
Older, cylinder-shaped LEDs. The light is projected more forwards, which reduces the vertical angle. Still used outdoors for their robustness, but less effective in terms of angle.
At Proxiled, all our indoor screens (P1.89, P2.5) and most of our outdoor screens (P3.91) use SMD technology to guarantee an optimal viewing angle in every configuration.
How to choose the right angle for your project
Here are the questions to ask yourself before choosing:
Where will the screen be placed? High up (façade, totem) = the vertical angle matters. At eye level (shop window, stand) = the horizontal angle comes first.
Where does your audience come from? Pedestrians passing sideways = a wide horizontal angle is essential. Audience seated in front = the angle is less critical.
Indoors or outdoors? Outdoors, brightness partly makes up for a narrower angle. In a dark indoor space, every degree counts.
What content are you showing? Fine text = you need quality even from the sides. Dynamic video and bright colours = more tolerant of extreme angles.
Common mistakes to avoid
Relying solely on the manufacturer's specs. The stated angle is measured in a lab. In real conditions (ambient light, distance), the usable angle is often 10-20° narrower.
Installing the screen without thinking about orientation. A screen turned 15° towards the main flow can double its effective visibility.
Choosing a DIP screen for indoor use. Indoors, the reduced vertical angle of DIP LEDs is a real handicap if the screen is mounted high.
❓ Frequently asked questions
Viewing angles in the field: real examples from Proxiled
In more than 15 years of installations, we've come across every possible configuration. Here are three real cases that illustrate the importance of the viewing angle:
Car dealership
A dealer installed a P2.5 LED wall in their showroom. The screen is at the back of the room, but visitors come in from the side. Thanks to a 160° horizontal angle, the content stays perfectly readable from the entrance — visitors are captured before they're even facing the screen.
Roadside LED trailer
On a main road, cars approach at an angle. Our P3.91 LED trailer with a 140° angle ensures the message is visible from 200 metres away. The driver gets 5-8 seconds of reading time instead of 2 with a standard sign.
Trade show (Batibouw)
In a trade show aisle, 80% of visitors pass by the sides of the stand. An LED video roll-up with a wide angle catches sideways glances — the visitor turns their head, stops, comes closer. That's what starts the conversation.
Pro advice: optimise the angle through positioning
Even with a wide-viewing-angle screen, positioning remains decisive. Here are three simple rules our installers always apply:
Point the screen towards the flow, not the wall. If 70% of your visitors come from the left, turn the screen 10-15° in that direction. You make visual contact sooner.
Place the screen at eye level whenever possible. A screen that's too high reduces the usable vertical angle. In a shop window or on a stand, the ideal position is between 1.20 m and 1.80 m from the floor.
Use a slight downward tilt if the screen is high up. For screens mounted above 3 m (façade, structure), tilt them 5-10° downwards. This centres the best-quality zone on the audience below.
