Want to purchase an LED wall, but are confused in the flurry of too many options? With the escalating use of active LED display technology across several sectors, the display screens undergo continuous upgrade, getting finer, more reliable & adaptable. Therefore, an insightful understanding of SMD Vs GOB Vs COB leads your path to the right video wall solutions, defining your application purpose.
Brief Comparison of LED Display Technology: SMD Vs GOB Vs COB
SMD Technology: To start with, it is one of the traditional technologies of LED packaging, popularly known as Surface Mounted Device. Under this technology, LEDs containing red, green, and blue diodes are attached to the board one by one. As a result, with a sleek structure and efficient performance in terms of colour and brightness, SMD screens are perfect for both indoor and outdoor applications.
Compelling Properties
Firstly, offers good brightness with colour performance.
Secondly, comes with an easy-to-maintain design.
Advantages: Making SMD Screens A Fair Purchase
Workable in indoor, as well as outdoor environments.
Furthermore, cheaper when compared to GOB or COB display technology.
Drawbacks
However, less durability when placed in harsh environments due to exposed LED lamps. Indeed, discussing SMD Vs GOB Vs COB, displays made with SMD technology are prone to damage by external environmental elements.
Additionally, more consumption of power in comparison to the other two technologies.
Further, needs additional cooling devices.
GOB Display Technology: Moving on, running a check through developing LED display technologies, GOB (Glue-on-Board) is a step ahead of SMD. In this technology, the arrangement of LED bulbs is similar to that in SMD displays. But after the LED modules are attached to the board, a transparent glue called epoxy resin is coated over the modules to make them resistant to dust, water, or moisture.
Resultantly, more expensive than SMD, it offers ultimate damage protection when used in difficult environments. Moreover, displays designed with this technology don’t require frequent maintenance, thereby saving repair expenses at the end of the day.
Primary Features
Dustproof, waterproof, with anti-collision properties.
Benefits: GOB Displays Offer
With epoxy resin coating, these are highly protected against dust, water, or moisture damage.
Hence, suitable for close-contact indoor spaces, such as corporate lobbies and retail outlets, where viewers can touch the screens.
Disadvantages
Doubtlessly, a thoughtful comparison of SMD Vs GOB Vs COB is incomplete without reviewing flaws. In GOB LED displays, heat rejection is a bit inferior to that of SMD screens.
Low in brightness when compared to SMD displays because of the protective layer of glue.
Naturally, more expensive than SMD ones, as they offer better protection.
COB Technology Of Display Screens: Essentially, it is an advanced technology called Chip on Board (COB), where small LED chips are arranged with minimal spacing, directly on the printed circuit board ( PCB). Providing ultra-fine visuals using LED chips, this technology offers additional protection against dust, moisture, plus humidity, covering the surface with a glue coating.
Key Traits
Single module calibration, eliminating patches with colour differences.
In addition, remarkably high resolution image quality.
High in brightness, refresh rate, or contrast ratio.
Long life with energy-efficient technology.
Also, more than 160 degrees horizontal, combining vertical viewing angle.
Strengths
Ultra-fine pitch ranging from 0.9mm to 1.8mm, flawless surface
Besides, better heat rejection technology
Extended Screen Life
Understand SMD Vs GOB Vs COB Better
| Comparision Parameter | SMD | GOB | COB |
| Brightness | High in Outdoor Displays | Slightly less due to the glue coating | Very high indoor brightness |
| Durability | Adequate Open LED Lamps | Waterproof, dustproof, impact-resistant | LED chip design, resilient surface protection |
| PowerConsumption | Medium | Higher than COB | Less |
| Price | Cheaper option | Slightly higher Protective coating | Expensive Ultra-fine picture quality |
Application of SMD, Vs GOB, Vs COB Visual Technology
After a brief understanding of all three technologies, the users must have an insight into the scope of their application zones:
SMD Displays: Screens based on SMD are affordable with an easy-to-repair or upkeep design. Consequently, these are a favourable option for indoor including outdoor spaces. Thus, first-time users with projects demanding long-standing stability can go with them.
GOB Screens: With a protective coating of transparent glue, these displays are dustproof, moisture or water-resistant. Hence, such screens are an advisable solution for indoor spaces like showrooms, corporate spaces, or retail selling stores where people are close to the display.
Fine-Pitch COB LED Screens: Providing fine-pitch display quality, high screen refresh, in addition to moisture-proof properties. Advanced COB screens in pixel pitch 0.8, 1.2, 1.5, or 1.8mm are preferable for conference rooms with control centers. Moreover, you can use them for home entertainment spaces, including broadcast studios.
Conclusion
Finally, comparing SMD Vs GOB Vs COB, we can say that every technology has its positives or negatives. Ultimately, based on the environment and the budget, including your project requirements, you can choose what aligns with your goals the best.
