Refresh Rate
High refresh rate over 1920Hz and even up to 7680Hz, and eliminates module flicker problems.
COB LED displays Screens, using Chip-on-Board technology, represent a leap in LED display innovation by mounting several LED chips directly onto the substrate, creating a seamless, compact, and highly effective light source. This eliminates traditional LED packaging, which results in a high-density configuration with great improvement in image clarity and color vibrancy.
COB LED displays have unparalleled definition and impressive energy efficiency with smaller pixel pitches. They still boast superior heat dissipation, high durability, and broad viewing angles, hence ideal for situations that demand rigorous performance from them. They are also used in control rooms, broadcasting studios, and shopping centers because they are appropriate for high-resolution displays. Different types of pixel pitches include p1.25mm, p1.5mm, p1.8 mm, etc.
The GOB LED display offers superior color consistency and wide viewing angles, giving rich and uniform display color from nearly any direction. Its high-level protection renders these LED screens suitable for easy transportation, with no risk of damage while in transport. This robust construction effectively prevents damage to the LED lamp beads, making them long-lasting and dependable for application in various uses.
COB and  GOB LED Screens are widely used in LED displays, however, they have some differences as follows:
| Feature | COB LED Screen | GOB LED Screen |
| LED Packaging Technology | Chip-on-Board (multiple LED chips directly integrated on PCB) | Glue-on-Board (SMD LEDs sealed with transparent epoxy glue) |
| Protection Level | Extremely high protection (fully sealed surface) | High protection (glue layer protects LED lamps) |
| Water & Dust Resistance | Excellent waterproof and dustproof performance | Good water and dust resistance |
| Shock & Impact Resistance | Very high resistance to impact, pressure, and accidental touch | High resistance, but less than COB |
| Viewing Angle | Ultra-wide viewing angles up to 170° | Wide viewing angles up to 160° |
| Durability | Extremely durable, ideal for long-term use | Durable and suitable for most indoor environments |
| Visual Quality | Pure black surface, excellent contrast, uniform colors | Good color performance with slight surface reflection |
| Pixel Pitch Capability | Best for ultra-fine pixel pitch (P0.6–P1.5) | Suitable for fine pixel pitches (P1.2–P2.5) |
| Maintenance | Difficult to repair individual pixels; usually module replacement | Easier maintenance than COB |
| Cost | Higher cost due to advanced manufacturing | More cost-effective than COB |

Typically, LED displays use pre-assembled SMD LEDs, which may be subject to issues such as pixel damage, decreased contrast, and heat concentration. COB technology, on the other hand, mounts LED chips directly to the PCB board and seals them with a protective layer, providing greater stability, protection, and display quality for professional use in indoor environments.
COB technology-based LED displays come equipped with a sealed surface technology, which provides better protection to the LED chip against dust, moisture, oxidation, and accidental impacts. The protective encapsulation layer prevents pixel drop, ensuring the screen does not get damaged during the course of operation.
COB technology allows for ultra-fine pixel pitches like P0.9, P1.2, and P1.5, offering clearer images and higher resolutions, even when viewing is close up. COB technology is thus suitable for meeting rooms, control rooms, broadcast studios, and business settings.
Direct Chip Bonding technology allows for efficient heat dissipation, thus ensuring brightness and performance and increasing the lifespan of the screen compared to conventional LED technology.
A COB LED Screen is a technology that allows LED chips to be mounted directly onto a PCB board and then given a protective layer, making it more durable, stable, and with better display capabilities than a traditional SMD LED Screen.
The advantages of COB LED Screens over SMD LED Screens include better surface protection, better heat dissipation, better reliability, better contrast ratio, and better pixel failure rate. COB LED Screens also have better dust, moisture, and impact resistance.
The pixel pitches that COB LED Screens have include ultra-fine pixel pitches like P0.9, P1.2, P1.5, and P1.8, making it more suitable for use indoors.
Yes, COB LED Screens are highly suitable for use in Conference Rooms, Control Rooms, Broadcasting Studios, and corporate environments owing to the high contrast ratio, high resolution, and flicker-free display.
No, COB LED Screens feature a protected surface that minimizes the risk of damage and dust accumulation, resulting in lower maintenance requirements.
