I. What is LED Pixel Pitch? Why is it so important?
LED pixel pitch refers to the distance between the centers of two adjacent LED lamp beads, measured in millimeters (mm).
P1.5 = 1.5mm
P1.8 = 1.8mm
P2.0 = 2.0mm
The smaller the pixel pitch:
The higher the pixel density
The finer the image
The less noticeable the pixelation at close viewing distances
The higher the cost
In conference rooms, where the display content mainly consists of text, PPT presentations, and tables, the pixel pitch significantly impacts clarity.
II. How to Calculate Pixel Pitch for Conference Rooms? (Common Engineering Method)
Industry General Rule of Thumb:
Optimal viewing distance (meters) ≈ LED pixel pitch (mm)
Based on practical engineering experience, you can directly refer to the table below:
Pixel Pitch | Recommended Viewing Distance | Suitable Conference Room Type
P1.5 | 2–4 meters | High-end conference rooms / Command centers
P1.8 | 3–5 meters | Most conference rooms (most commonly used)
P2.0 | 4–7 meters | Ordinary conference rooms / Training rooms
�� If the first row of seats in the conference room is about 3 meters from the screen, choosing P1.8 is generally a safe bet.
III. How to Choose Pixel Pitch for Conference Rooms of Different Sizes? 1. Small Meeting Rooms (20–40㎡)
First row viewing distance: 2–3 meters
Main display content: PPT, text, video conferencing
Recommended options:
Focus on clarity: P1.5
Focus on cost-effectiveness: P1.8
2. Medium-sized Meeting Rooms (40–80㎡) [Most common]
First row viewing distance: 3–5 meters
High frequency of use, requiring stable display performance
Recommended option: P1.8
Best balance of clarity and cost
Relatively low maintenance pressure
�� In actual projects, over 80% of meeting rooms choose P1.8
3. Large Meeting Rooms / Lecture Halls
First row viewing distance: 5 meters or more
Larger screen area
Recommended option: P2.0
More controllable cost
No noticeable pixelation at long viewing distances
IV. P1.5 / P1.8 / P2.0 Comparison Table
Comparison Item P1.5 P1.8 P2.0
Display Clarity ★★★★★ ★★★★☆ ★★★★
Recommended Viewing Distance 2–4 meters 3–5 meters 4–7 meters
Cost Level High Medium (Best cost-effectiveness) Low
Meeting Room Applicability Medium Highest Lower
V. Three Common Misconceptions in Meeting Room Pixel Pitch Selection
Misconception 1: Smaller pixel pitch is always better
P1.5 is indeed clearer, but at viewing distances of 4 meters or more, the difference is not significant to the naked eye, while the cost increases by 20%–30%.
Misconception 2: Only considering price, ignoring viewing distance
Choosing P2.0 at close distances can easily lead to blurry text edges and noticeable pixelation.
Misconception 3: Ignoring the type of display content
Meeting rooms mainly display text, tables, and PPTs, requiring high clarity, so the selection criteria cannot be the same as for exhibition halls or advertising screens.
VI. Summary of Engineering Experience in Meeting Room LED Screen Selection
In actual meeting room projects, the following selection suggestions are commonly used:
Within 3 meters: Prioritize P1.5
3–5 meters: P1.8 is the first choice
5 meters or more: P2.0 is more economical
If the budget is limited, it is better to appropriately reduce the screen size than to lower the pixel pitch level. VII. Summary in one sentence:
For most conference rooms in China, the P1.8 LED display strikes the best balance between clarity, viewing distance, and budget, making it the most recommended pixel pitch option.
