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 |
LED light sensors automatically adapt LED screen brightness according to environment brightness and fulfill human eye requirements.
Made with first-class driver ICs ICN2037, ICN2038S, ICN2153, 2046, 2049, 6363, etc.
High refresh rate over 1920Hz and even up to 7680Hz, and eliminates module flicker problems.
Ultra High Moisture-proof, Waterproof, Anti-collision to protect the LED bead.
High contrast ratio of 5000:1 adds depth and dimension to every frame.
160 viewing angles to minimize viewing blind spots and maximize visual coverage.
The Traditional LED displays are susceptible to environmental attacks such as water, dust, and accidental contact. GOB technology is safer with its highly protective glue-layer cover, making the display highly dependable.
GOB LED displays are protected against water, moisture, dust, impact, corrosion, blue light, salt spray, & static electricity. This makes them suitable for outdoor and rough environments where normal LED displays would be faulty.
The protective layer formed by the glue on the LED surface lowers the possibility of damage while installation, transport, and application, resulting in greater lifespan for the LED display.
GOB technology transforms the LED surface from a point source of light to a surface source of light, improving brightness uniformity and smoother display quality.
GOB stands for “Glue On Board,” which refers to the process of applying a transparent glue on the surface of the LED module. Generally we call these modules as GOB LED modules.
| Feature | GOB LED Screen | COB LED Screen |
| Structure | Glue layer over LED chips for added protection | LED chips directly on board, smooth surface |
| Protection | High protection: moisture, dust, shock, UV resistant | Moderate protection against environmental damage |
| Thermal Management | Enhanced heat dissipation due to glue layer | Efficient thermal management with chip-on-board setup |
| Maintenance | Easier, less costly maintenance | Difficult, costly due to complex repairs |
| Viewing Experience | Excellent viewing angle and consistency | May experience inconsistencies and granularity |
| Manufacturing | More complex production process | Simpler production but higher potential manufacturing costs |
Similar to the SMD LED module, the LED GOB display also has synchronous and asynchronous control methods:
GOB LED displays are normally much more expensive compared to SMD LED displays because of their complicated manufacturing processes and advanced protective features. The price is different depending on various screen sizes, cabinet types, LED brands, pixel pitches, power suppliers, etc.
