Every week, someone asks us essentially the same question:

“I need an LED video wall for a conference room, control room or lobby. What pixel pitch should I choose? And is COB really worth the extra money?”

We manufacture fine-pitch LED displays from P0.625 to P2.5 using SMD, COB and MIP. So we’re not trying to push one technology on every project. We have a factory with all three.

In practice, we start with the room, the viewing distance and how the screen will be used. The technology comes after that.

First: What Pixel Pitch Do You Actually Need?

Pixel pitch is the distance between two neighboring LED pixels, measured in millimeters. Smaller pitch means more pixels and a cleaner image at close viewing distances.

For a quick starting point, we normally use:

Viewing distance in meters ≈ pixel pitch in millimeters.

It’s not a strict formula, but it’s surprisingly useful.

The important part is the closest viewer.

If everyone sits four meters away, there may be little reason to pay for P0.7. If someone will regularly stand 1.5 meters from the screen, P2.5 may be too coarse.

Don’t buy resolution you can’t see — but don’t save money where people will notice the pixels every day.

COB vs. SMD vs. MIP

This is where most of the confusion starts.

SMD: Still a Very Good Choice

SMD uses individually packaged LED components mounted onto the PCB. It’s mature, widely used and generally more cost-effective.

For controlled indoor environments, particularly around P1.5–P2.5, SMD can be the most sensible choice when budget matters.

Another advantage is serviceability. Depending on the design, individual LED components or modules can be replaced relatively easily.

We wouldn’t call SMD “old technology.” It’s still a very practical solution for a lot of projects.

COB: Why It Costs More

With COB, the LED chips are mounted directly onto the PCB and encapsulated.

That gives the front surface a different structure: it’s flatter, more protected and less exposed to physical contact. This becomes particularly useful with fine-pitch displays installed in public or high-use environments.

COB is also well suited to very small pixel pitches because bare chips can be placed more densely than conventional LED packages.

The downside is simple: COB usually costs more, and repairs are generally handled at module or board level rather than replacing one individual LED package.

So, is COB worth the extra money?

For many premium indoor fine-pitch projects, yes.

For every project? No.

If the screen is in a controlled room, nobody touches it and budget is tight, SMD may still be the better value.

MIP: When Consistency Matters More

MIP packages Mini LED chips before they are placed onto the PCB. This allows the packages to be tested and controlled before assembly, which can help improve consistency and production yield.

It becomes more interesting for broadcast, virtual production, premium retail and other applications where close viewing or camera performance makes pixel consistency especially important.

It’s also normally the most expensive option.

A simple comparison:

These are general technology characteristics. The actual result still depends on the LED package, driver IC, PCB, cabinet design and calibration.

LED or LCD?

LCD still makes sense.

For smaller displays, controlled lighting and budget-sensitive projects, commercial LCD can be difficult to beat on initial cost.

The problem becomes more obvious as the wall gets larger.

LCD has bezels between panels. Even narrow bezels are still visible. LED gives you one continuous image without those physical seams.

That’s why LED becomes particularly attractive for:

• Large conference rooms
• Control rooms
• Broadcast studios
• Corporate lobbies
• Experience centers
• Premium retail

Brightness is another consideration, especially in rooms with strong daylight. For a deeper look at how LED video walls are built and spliced, see our complete 2026 guide to LED video walls.

There isn’t a magic “100-inch rule” where LED suddenly becomes better. Screen size, viewing distance, room lighting, budget and tolerance for bezels all matter.

And for conference rooms, don’t forget about all-in-one LED. Canbest’s CTV Series currently includes 108″, 135″, 163″ and 216″ configurations, while the UTV Fold Series is a 135″ foldable COB all-in-one display.

Sometimes the simplest system is the right one.

Three Specifications Buyers Often Overlook

Refresh Rate

For normal conference rooms, corporate displays and signage, 1920–3840Hz is generally sufficient.

For camera-facing applications, we normally recommend 3840Hz or higher. For demanding broadcast or virtual production, 7680Hz can provide additional margin.

But don’t judge camera performance by refresh rate alone. Driver IC, scan mode, PWM characteristics, synchronization, camera shutter speed and camera frame rate all matter.

If cameras are involved, test the complete LED system.

Brightness

Indoor fine-pitch LED generally doesn’t need extreme brightness.

For many indoor applications, 600–1,000 nits is a reasonable range, depending on the room.

More brightness isn’t automatically better. It can mean more power, more heat and an uncomfortable viewing experience.

A conference room doesn’t need the same brightness as an outdoor billboard.

L70

L70 is often misunderstood.

It means the LED’s light output is expected to decline to approximately 70% of its initial level at the specified number of hours.

If the display starts at 1,000 nits, reaching L70 means roughly 700 nits.

It does not mean the display stops working.

L70 is a light-output degradation metric. Actual service life depends on operating hours, brightness, temperature, thermal design, LED package and maintenance.

So when a supplier says “100,000-hour lifespan,” ask whether they’re talking about L70, MTBF or something else. Those numbers don’t mean the same thing.

For a full breakdown of L70, real-world lifespan by application, and what the 100,000-hour figure actually means, see our LED display lifespan guide.

What We Actually Build

We make several fine-pitch LED platforms because different rooms call for different solutions.

For very fine indoor applications, our DM COB Series covers P0.7, P0.9, P1.25 and P1.56, with optional power and signal redundancy depending on configuration. It’s one of the ranges we normally look at for control rooms and other reliability-focused projects.

The UE Series goes down to P0.625 for applications that genuinely need very high pixel density.

For projects where pixel consistency is a major consideration, we offer the U MIP Series at P0.9.

The U Slim COB Series offers P0.9, P1.25 and P1.56 where cabinet depth is also important.

For home theater applications, the DM Cinema Series covers P0.9 and P1.25.

For more general indoor installations, the V COB Series covers P1.25, P1.56 and P1.9, while the SPRO Series provides a more cost-conscious SMD option at P1.2, P1.5 and P1.8.

For North American projects, our FIW Series covers P1.25, P1.53, P1.86, P2 and P2.5 and is ETL certified.

For broader indoor applications, the V Series covers P1.2 through P2.9 with multiple cabinet formats.

We also have outdoor fine-pitch options, including the APro-ULT COB Series at P1.5 and P1.9, and the APRO-H Series from P2.9 upward for larger outdoor installations and curved or corner configurations.

The point isn’t that one of these products is always the best.

The room determines the starting point.

So, What Would We Recommend?

If you want a quick answer, give us three things:

Screen size + closest viewing distance + application.

For a typical conference room, we’d usually start somewhere around P1.2–P1.9, depending on the room.

For a control room, we’d look more closely at P0.9–P1.2, reliability and redundancy.

For broadcast or virtual production, we’d add camera testing and look beyond refresh rate alone.

For a budget-conscious indoor project, SMD may be the smarter choice.

For a premium fine-pitch installation where surface protection and close viewing matter, we’d normally look at COB.

And for a large conference room where installation simplicity matters, we’d compare an all-in-one LED system with a conventional LED wall before making the final call.

The pitch comes from the viewing distance.
The technology comes from the application.
The price comes from the complete system.

That’s how we’d approach it if you were standing in our showroom asking us the same question.

Quick Answers

What is a fine-pitch LED display?
A direct-view LED display designed for relatively close viewing, generally around P2.5 and below, with many premium products extending below P1.0.

COB or SMD — which is better?
COB is usually the better fit for premium fine-pitch applications where surface protection and close viewing matter. SMD remains a strong choice when budget and serviceability are more important.

How do I choose pixel pitch?
Start with the closest viewing distance. As a quick rule, viewing distance in meters ≈ pixel pitch in millimeters.

Do I need 7680Hz?
Not for most conference rooms. 1920–3840Hz is generally sufficient. For camera-facing projects, 3840Hz or higher is a better starting point.

What does L70 mean?
The point at which the LED’s light output is expected to reach approximately 70% of its original level. It is not the point at which the screen stops working.

Is COB worth the extra money?
Often, but not always. If the room is controlled and budget matters, SMD may be the better value. If the screen is viewed closely or needs a more protected surface, COB can justify the premium.
