There is an expected 4.9 percent in the global market value of the LED display industry in the coming 2029 from its recorded value last 2022. The major cause of this industry boom is the introduction of many technologies that improved the quality and operation of LED screens all over the world. One of these popular technologies is the GOB LED

Compared to the recent introduction and rise of mini LED and micro LED, this technology is older but still necessary for the evolution of LED displays. Popular for a few years, GOB LED screens have now become a solid technology that does not need further knowing and exploring. This technology was brought to life as a solution to issues experienced when using COB LED displays. 

If you’re planning to invest in GOB displays, diving deeper into what this technology brings and what it can do for your goals is best. The first step is understanding what it means and what makes it different than other LED technologies, old and new ones. 

What is GOB LED?

GOB LED - Glue on Board
GOB LED – Glue on Board

The letters G-O-B in the GOB LED display stand for “glue on board”, which refers to the added protection laid out for this kind of screen. The focus of this technology is on the module’s protection, ensuring that it is properly encapsulated by a transparent glue that covers the surface of the PCB board. The glue acts as a shield to all the LEDs soldered on the board. Ultimately, it becomes a high-protection LED display module that’s stronger and more durable. 

The development of GOB LED technology came from the need to protect modules from getting damaged while transporting them on delivery. Accidents on the road and sudden shifts can result in the modules breaking. It is one of the major flaws that LED modules had before the innovation of the GOB technology. 

GOB LED screens are popular for being durable devices. These displays are shock-proof and won’t easily break upon delivery. This means that the LED modules are more durable and stronger. They feature high thermal conductivity and transparency performance. And since they are meticulously protected, they are guaranteed to last longer. 

How is a GOB LED screen produced?

The GOB LED display is produced by following a very specific set of steps. First, choose the materials of the parts you’ll need to assemble, which include the following:

  • Lamp beads
  • LED chips
  • Brush IC solutions

Once the products have been assembled, the next step is to wait 72 hours to completely age the product before adding the GOB filling. After which, the lamp will be tested. 

You will need to wait for another 24 hours to completely age the product for the second time. This will guarantee the quality of the product. 

Types of GOB LED Displays

If you’re getting your own GOB LED screens, consider and check out all the different types of displays within this category. Here are some of the most popular types you can check out and explore before making a decision. 

Small Pitch GOB LED

A small-pitch GOB LED display simply refers to screens with pixel pitch around P0.9, P1.2, and P1.5. All LED screens with a pixel pitch below 2.5mm are categorized as small-pitch LED displays. These screens have soldered LED lamps that are too small and when there’s a collision, they tend to be broken easily. The corners are the most vulnerable areas on the screen and are the most prone areas of the device. 

Protection is a hurdle that many were experiencing with small-pitch LED screens and so with the changes in the modules of the glue-on-board, these LED screens become more durable and won’t have to be handled so meticulously unlike in the past.

Floor GOB LED

A floor GOB LED screen is a standard floor LED display but the difference is that there’s an acrylic cover that’s placed on the module for additional protection on the surface. This is very important for this type of display since they will be stepped on and so will be more prone to collision and a bit of force. The integration of this technology offers better visual effects and light transmission for the displays. 

With the added protective structure, the floor LED screens become more durable and less likely to get damaged with simple weight. They also become more dust-proof and water-proof because of the protective glue rather than the conventional acrylic screen layer. 

Flexible GOB LED

The flexible GOB LED display refers to LED screens with a protective cover that can come in a variety of shapes and sizes. The modules used in these displays are considered to be soft modules and so can contour depending on the surface it’s installed in. It can easily be bent even up to 360 degrees. With the application of GOB technology, the LED screen increases its reliability and durability, making the modules an improved version of the standard flexible LED screens. 

These flexible displays with GOB modules are guaranteed to be scratch and dust-proof, as well as moisture-proof, and can resist collision easily. They are the ideal alternative for a curved screen, especially if you’re planning to use a gigantic ensemble. 

Irregular GOB LED

GOB LED screens also come in irregular shapes. These are popular in artistic venues like museums and exhibit halls. You can even find some in quirky and unique clubs. Compared to the flexible types, these irregular-shaped LED displays have a definite shape, unlike flexible ones with unlimited possibilities. 

Integrating GOB technology helped deal with the large maintenance costs that often come with these irregular-shaped LED displays. Making them more durable and a lot sturdier helps save so much from these costs. 

Transparent GOB LED

Transparent GOB LED displays are the sturdier version of the elegant transparent screens often installed on the facade of buildings for commercial purposes. They are popularly used in business locations like shopping malls and retail stores. They become less prone to damage even with collision and make sure that the transparency and resolution are protected.

GOB LED displays became popular in the global market because of the benefits you can take advantage of. In contrast, you should also know the drawbacks that come with these devices and the technology they offer. Here is a list of their advantages and disadvantages.

Advantages

High-Quality Protection Characteristics

GOB LED screens are designed with high protective qualities that can be considered improvements on the standard displays. The protective characteristics of these displays are upgraded using advanced material for added protection on the substrate. Some of these are the following:

  • Anti-collision – The risk of damage in terms of collision is reduced because of the protective glue sealing on the board.   
  • Shock-proof – Considering the LED displays are shock-proof, they won’t break during delivery, transport, or installation, unlike other LED screens. 
  • Anti-knock – With the glue holding everything together and protecting the LEDs, a knock on the screen won’t cause damage or cracks. The glue serves as a barrier for such cases. 
  • Dust-proof – These screens are structured to be protected from dust and so guarantee to avoid damage brought by this external factor. 
  • Water-proof – The technology applied in these displays helps them be waterproof and resistant to weather elements, including moisture and rain. 

Highly Reliable

GOB LED displays are highly reliable in their operations and functions. They are designed to be more durable and resistant to external elements that can affect their operations. Because of the structure, the screen can operate effectively even after a bumpy ride from the delivery point. Besides that, you can also be at ease even when you’re using the LED display in harsh environments, from the heat of the sun to possible dust and water particles. 

Superior Thermal Conductivity

GOB LED screens are guaranteed to have excellent thermal conductivity, which means that the materials used for the creation of the LED display have efficient heat transfer when operating. This will further help in the operation and functionality of the screen. 

Disadvantages

Risk of Thermal Alteration

GOB LED screens are prone to degumming and colloid discoloration. This is brought by the tendency of the devices to repeatedly and alternately go hot and cold. 

Hard to Repair

When the glue has been taken off due to collision, it means that the screen has been truly damaged. In the end, it will be difficult to put it back into a state of being functional again. 

PCB Board Can Be Deformed

LED screens have PCB boards that are susceptible to deformation. The flatness of the display may be affected due to the glue cover when under high stress. 

Possible Secondary Image

There’s a possible secondary image when the GOB LED display is operating if the colloid of the glue somehow covers the surface. The optical image is not a pleasant visual effect and can be annoying to look at.
