LED posters have become an important tool for commercial display and brand promotion. They have been widely used in luxury windows and car showrooms. Among them, P2 LED display posters are one of the most popular options. So, what is the P2 LED poster? What is the difference between it and the P3 poster, GOB packaging and SMD technology? SightLED will analyze it in detail for you.
What Is a P2 Digital LED Poster?
A digital LED poster is a modern display solution commonly used in both indoor and outdoor environments to present information, advertisements, or promotional content.
The term P2 refers to the pixel pitch of the LED screen,which is the distance (in millimeters) from the center of one LED pixel to the center of the next. The number “2” means that the distance is 2 millimeters.
Pixel pitch is a key indicator of display resolution and visual clarity. A smaller pixel pitch, like P2, means that the pixels are packed more closely together, resulting in finer detail, smoother images, and better visual performance.

P2 vs P3: How to choose the model that suits you?
The biggest difference between P2 and P3 is the pixel pitch. P2 is 2mm, while P3 is 3mm. This 1mm difference makes a significant difference in different usage scenarios:
P2 vs P3 LED Poster Comparison
| Comparison Item | P2 LED Poster | P3 LED Poster |
|---|---|---|
| Pixel Pitch | 2.0 mm | 3.0 mm |
| Pixel Density | Higher (250,000+ pixels/m²) | Lower (Approx. 110,000 pixels/m²) |
| Display Quality | Finer, sharper, smoother color transitions | Coarser, visible pixels at close range |
| Viewing Distance | 2–5 meters | 3–8 meters |
| Cost | Slightly higher | More affordable |
| Best Use Cases | High-end indoor display, close-up viewing | Trade shows, general commercial advertising |
Summary Recommendation
- Choose P2 if you’re targeting high-end venues like luxury retail, banks, or brand showcases due to close viewing and premium image quality.
- Choose P3 if your budget is limited and you’re using it in common environments , such as exhibitions, corridors, or general advertising.
P2 GOB and P2 SMD LED poster:How to Choose?
What is GOB?
GOB is a transparent glue layer applied over the LED surface to enhance protection against impact, moisture, and dust LED packageing. It can make the display more durable for demanding environments.
P2 GOB vs P2 SMD LED Poster Comparison
| Comparison Item | P2 GOB Poster | P2 SMD Poster |
|---|---|---|
| Encapsulation Type | GOB (Glue-sealed protection) | SMD (Three-in-one surface mount) |
| Impact Resistance | Very strong, can be cleaned by hand | Fragile, easily damaged |
| Dust & Water Proof | Superior (supports indoor semi-outdoor use) | Standard protection |
| Brightness | Slightly lower (due to glue layer) | Higher brightness |
| Maintenance Difficulty | Higher (sealed layer is harder to remove) | Easier to maintain |
| Cost | Slightly higher (additional glue process) | More affordable |
Recommendation
- Choose GOB if the poster will be frequently moved, touched, or used in environments like showrooms, rental setups, or semi-outdoor areas.
- Choose SMD if the poster is used in a fixed indoor location and budget is limited, as it offers good performance at a lower cost.
P2 LED Poster Display Price
The P2 poster price is affected by many factors, such as packaging technology (GOB/SMD), control system, brand, size specifications, etc. Here is the current market price range:
| Configuration Type | Encapsulation | Control Method | Estimated Price (USD) | Remarks |
|---|---|---|---|---|
| Standard Version (640×1920) | SMD2121 | USB / Android | $1,000 ~ $1,350 | Single unit, includes stand |
| High Brightness Version | SMD2121 | Multimedia Cloud Control | $1,300 ~ $1,500 | Ideal for malls, retail, and brighter indoor environments |
| GOB Protective Version | GOB | Cloud System | $1,400 ~ $1,700 | Durable design, suitable for rentals and heavy usage scenes |
| Multi-screen Splicing (5 Units) | SMD / GOB | Cloud Synchronous Control | From $7,000+ | Supports synchronized playback, complete bundled solution |
GOB enhanced model:
- Basic protection: +20% unit price
- Outdoor poster level: +60-80% unit price
P2 LED display poster Cost structure analysis
Take a 20m² project as an example:
- LED chip: 42%
- Driver IC: 18%
- Structural parts: 15%
- Power system: 12%
- Control system: 8%
- Others: 5%
Although the price of P2 Poster is higher, the commercial value it brings far exceeds the cost difference. For example, in high-end retail stores, P2 LED poster can increase customer stay time by 45%, increase conversion rate by 22%. They can have a significant return on investment.
Conclusion
P2 LED poster have advantages such as HD picture quality, flexible installation and intelligent control. If you have high requirements for picture quality and the viewing distance is within 3 meters, we recommend choosing P2 instead of P3; if the environment is complex, frequent movement is required or there is a risk of touch, we recommend giving priority to GOB packaging; if you are using it for ordinary commercial display scenes with limited budget, then the SMD packaging + P3 combination is a cost-effective choice;
