SMD, COB, and GOB describe how individual LEDs are packaged and mounted onto a display module — and that packaging choice directly affects image quality, durability, and cost. We've covered each technology in depth separately: see SMD vs. DIP displays and GOB (Glue on Board) technology for the full technical breakdown of each. This guide puts all three side by side so you can choose the right one for your project.
The short version: SMD is the most common and cost-effective, COB delivers the best image uniformity and durability for fine-pitch screens, and GOB adds a protective resin layer over SMD packages to improve impact and moisture resistance for high-traffic environments.

The industry-standard packaging for most indoor LED screens: cost-effective, widely available, and proven at scale. Full comparison in our SMD vs. DIP guide.
For most indoor retail, corporate, and event screens viewed from a comfortable distance, standard SMD remains the most cost-effective choice. For high-traffic public spaces, touch applications, or fine-pitch screens viewed up close — such as our Fine-Pitch Rental LED Stage project — COB or GOB technology delivers better long-term durability and image consistency.
Budget, viewing distance, and environmental exposure should all factor into this decision alongside pixel pitch itself.

LED chips are mounted directly onto the PCB and encapsulated as a single unit, improving colour uniformity and durability — the preferred approach for the finest pixel pitches and high-impact public environments.
After COT treatment, the occurrence of yellowing, blistering and delamination caused by extreme temperature will be effectively reduced .
After COT treatment, the occurrence of thickness difference, unevenness and color difference will be effectively reduced.
Choosing between SMD, COB, and GOB isn't just a technical detail — it determines how close viewers can stand to the screen, how the display holds up in high-traffic or touch-prone environments, and where your budget goes. This decision works hand in hand with pixel pitch selection: the finer the pitch, the more the packaging technology affects both cost and visual consistency.
For touch-enabled fine-pitch displays in particular, GOB and COB technologies are increasingly preferred over standard SMD because of their added surface durability.
High resolution LED display form the visual backbone of immersives stores. They can be integrated into walls, ceilings, windows or custom structures.
Touch, motion or sensor-based interactions turn customers into active participants.
Digital content supports storytelling, product launches and brand messaging.

What is the difference between an immersive showroom and a traditional showroom?
An immersive showroom focuses on experience and storytelling rather than static product display.
Are immersive showrooms suitable for B2B brands?
Yes. Immersive showrooms are particularly effective for B2B demonstrations and complex products.
Can immersive showroom content be updated?Yes. Content is fully digital and can be updated easily.
A protective resin layer is applied over standard SMD packages, adding impact, moisture, and dust resistance without the full cost jump to COB. Full breakdown in our GOB technology guide.
What is the difference between an immersive retail and traditional retail?
Immersive retail focuses on experience, storytelling and interactions rather than satic product display.
Are immersive retail solutions scalable?
Yes. LED-based retail installations are modular and easily upgradable.
Is immersive retail suitable for all brands?
From luxury to mass-market brands, immersive retail can be adapted to different budgets and identities.
Reduce the number of scans while designing the display. It is recommended that the number of scans not exceed 16 scans for shooting applications.
Prioritize the reduction of current to reduce brightness, and preset multiple brightness adjustment modes that prioritize the use of current.
Driver IC mode adjustment.
Random scanning.
Frame tracking technology to reduce black field waiting time.
Genlock function of the controller to synchronize the LED display with the camera, and fine-tune the phase of Genlock
From the relationship between camera exposure time and LED display frame rate, we can determine the proper combination of shutter angle and frame rate for the most optimal shooting result.
We can support frame multiplication, allowing for expansion of frame rate.

The programming of classical LED Mesh and LED Mesh Curtain can be done using a smartphone, tablet PC or other remote device. The media facade can easily be live controlled from anywhere.
LED Mesh outdoor facade has a simple assembly concept. Though our specially designed clip-technology systems, the LED-profiles and the universal connector system are very easy to install. And, if necessary, they can quickly and smoothly be replaced on location by our team or any Mesh trained person.
Both the full video-based media facade systems feature an infinite number of colors, a high brightness, resolution and refresh rate for an incredible and creative result on the facade. For both Classical LED Mesh and LED metallic Mesh curtains.
To ensure a 24-hour operation anywhere in the world our Classical LED Mesh and metallic LED Mesh curtain façade are available with a maximum brightness > 11000 nit (cd / m²). At dusk or at night the system can continuously be dimmed, automatically or manually.
Even though LED Mesh curtains are composed of stainless steel on which are attached LED strips, that make it a massive structure, they have the advantage of having a homogeneous appearance. The LED strips are attached to the reverse side of the wire mesh maintaining the homogenous look of the façade at all times. The Metallic LED Mesh panel is regular. The inconspicuous cabling of each profile is not visible from the outside and with the high transparency of the mesh, the translucent look of the facade is maintained from both inside and outside.The shape and size of the media screen does not have to be the same size as the mesh facade. Since the LED strips are attached to the reverse side of the Mesh wire, they are hidden by it, therefore it becomes invisible. LED Mesh curtain wire are a design piece on their own. Therefore, even when the LED are off, the Mesh becomes an object of decoration and not a simple screen.
