Comparison between SMD, GOB, and COB LED panel technologies

Display Technology

SMD, GOB & COB Panels

We select the panel type according to where your screen will be installed and your budget requirements.

Surface Mounted Diode (SMD) is the standard industry-grade technology. The light diodes are soldered directly to the circuit board. Highly recommended for standard indoor walls, concert screens, and outdoor billboards where the panels are out of physical reach.

Most cost-effective
High brightness
Easy diode-level replacement
Mature manufacturing

Glue-on-Board (GOB) applies a clear protective optical sealant over SMD modules. This layer shields the delicate diodes from impacts, liquids, and humidity. It is the perfect upgrade for shopping malls, directories, and corporate receptions where people might bump into the screen.

Impact & shock resistant
Waterproof screen front
Anti-static design
Smooth visual surface

Chip-on-Board (COB) mounts micro-LED chips directly onto the board and coats the surface with a continuous protective resin. Eliminating individual pixel package frames, COB creates ultra-rich black ratios and extreme viewing angles. Best suited for high-end corporate conference rooms, broadcast rooms, and 4K close-proximity displays.

Deepest contrast ratios
Ultra-fine pixel pitches
High energy savings
Widest viewing angles

How We Work

Our Installation Process

We follow a strict engineering workflow to ensure maximum diode reliability, calibration accuracy, and service life.

Consultation & Pitch Selection

We review your location layout, ambient lighting levels, and target viewing distances. We then advise whether SMD, GOB, or COB is best, and calculate the optimal pixel pitch.

Custom Framing & CAD Design

Every building facade and corporate lobby has different load capacities. We engineer custom aluminum or steel mounting structures, mapping precise power load paths for cooling and stability.

Installation & Controller Mapping

Our skilled technicians assemble the panels and run high-efficiency power supplies and data links. We program the controllers (Novastar, Huido, Colorlight) for precise pixel mapping and color accuracy.

Burn-In Testing & Handover

We conduct a rigorous 72-hour continuous burn-in test running different contrast cycles to isolate and repair any diode defects. Once verified, we hand over control and provide user training.

Client Feedback

Trusted by Local Businesses

Read how we helped companies in Dhaka optimize their advertising and reception spaces with custom displays.

“We hired Supreme Trading BD to construct a curved P1.2 reception screen. The display has zero seams, the neon colors are extremely sharp, and their structural framing was solid. Truly premium workmanship.”

Rahat Alom

Operations Lead, Dhaka Tech Solutions

“They restored an old P3.0 outdoor billboard that was crashing regularly. Their technician quickly mapped our Colorlight controller, swapped out the failing power modules, and solved the issue. High quality service.”
