Cob is an advanced led packaging technology that directly encapsulates led chips on PCB boards.
Technical features
1. High resolution: achieves smaller dot spacing.
2. High protection: IP protection level up to IP65, suitable for long-term harsh environments.
3. Wide viewing angle: up to 140° -170°, surface light source, good color uniformity.
4. High heat dissipation: The chip is directly attached to the PCB, and the heat is quickly dissipated through the copper foil, increasing the life of the led.
Cob led technology is accelerating the optimization and upgrading of traditional SMD packaging, which is an important development direction in the field of LED display.

| Feature | COB LED Display | SMD LED Display |
|---|---|---|
| Packaging method | Chip packaged on PCB | Independent LED chip patches for red, green, and blue LEDs |
| Display effect | Surface light source, more delicate colors, no obvious graininess | Point light source, slightly grainy when viewed up close. |
| Protective performance | The entire unit is encapsulated for shock, pressure, and dust protection, making it suitable for harsh operating environments. | The LED beads are easily dropped or damaged by impact, and the waterproof and dustproof rating is relatively low. |
| cost | High cost | High cost performance |
| Applicable Scenarios | High-end display scenarios | Suitable for viewing from medium to long distances |
Conclusion Round the LED COB is suitable for high quality image display, stability and protection of high-end applications, SMD led screen is suitable for low requirement of fine display, mid to long distance viewing application.
| Feature | COB LED Display | GOB LED Display |
|---|---|---|
| Packaging process | Template chip packaging | Transparent colloidal coating |
| Pixel pitch | P0.4 - P1.2 | P1.2 - P2.5 |
| Protective performance | Moisture-proof, dust-proof, and impact-resistant (suitable for long-term and harsh environments) | Water resistant, dust resistant and drop resistant. (excellent) |
| Applicable Scenario | High-end high-quality indoor scenes | Protective performance and cost-effective scenarios |
| costs | Suitable for high-end application planning with sufficient funding (slightly high budget). | Excellent value for money (moderate) |
In summary, cob is more suitable for high-end professional applications with extreme image quality and long-term stability, and GOB is more suitable for general applications with high demand for protection performance and cost performance.
The cob display brings ultra-high-definition and delicate image quality to high-end conference rooms, a true "cold screen" experience, highlights the international image of enterprises, improves communication efficiency, and provides a good tool for the design of intelligent business spaces.
The cob display enables broadcasters to ensure that the image quality in front of the camera is as fine as it is realistic, meets the requirements for long live broadcasts and broadcasts, and enhances the professionalism of the program in all aspects.
Cob brings 160-degree ultra-wide viewing angle and full-floor protection design to the home theater without fear of touch, creating a shocking and more authentic audiovisual experience, allowing you and your family to be part of it and providing a space for your family to interact.
The cob display provides a super-clear display for the command center, supports 7 × 24 hours of operation, enhances emergency command and data digital visualization capabilities, and is used to create an immersive dispatch command space for accurate decision-making and dispatch.
1. Flip-chip (vs Formal Impact: The price of flip-chip is higher than that of Formal cob.
2. Control system impact: 4K or 8K controllers are priced differently
3. Installation and structural impact: The die-cast aluminum box is different from the simple bracket
4. Also affected by product size, type, and customization Price
Formal cob: the chip is placing a pcb (with gold wire), the heat is generally dissipated, and the general spacing is
Flip cob: put pcb (no gold wire) on the chip inverted, heat dissipation is fast, and ultra-micro pitch is challenged
1. The dazzling feeling caused by the reduced luminosity of the surface light source.
2. There is almost no granularity when viewed up close (within 1 meter).
3. The all-black encapsulation material makes the black look more advanced.
Cob is a bracket that encapsulates the light-emitting chip directly on the PCB board, eliminating the need for a single lamp bead.It is not only completely encapsulated, but also waterproof, dustproof, anti-collision, anti-static, moisture-proof and other characteristics.Viewers don't have to worry about touching or accidental collisions, however the beads on the edge of the SMD screen can easily come off.
This is the user's top concern.Can it be repaired?
1.On-site repair: If the surface scratches slightly, it usually does not affect the display.
2.Professional maintenance: Send the entire module back to the manufacturer for precision maintenance by a professional mounting and packaging machine; or the manufacturer will send the appropriate accessories for you to repair., There are professional maintenance personnel, don't worry.
