Comprehensive Guide to GOB technology for LED displays

With the continuous development of the market and technology, the LED display industry has also ushered in many new breakthroughs. The rapid progress of technologies such as Mini LED, OLED, and Micro LED has injected new vitality into the industry. At the same time, LED packaging technology is also constantly innovating. Various packaging processes such as DIP, IMD, SMD, GOB, and COB have gradually matured and are widely used. Today, we will focus on how GOB technology can play a role in LED displays.

What is GOB technology？

GOB technology, namely “Glue on Board” technology, is a new type of LED packaging process. It uses special optical thermal conductive nano-filling materials. After a unique process flow, the PCB board and SMD lamp beads of the GOB LED module are combined with double matte optical treatment to form a frosted effect. Compared with traditional LED protection technology, GOB LED display not only improves the protection performance of LED display, but also innovatively converts point light sources into surface light sources, improving the display effect.

GOB technology solves the pain points of the LED display industry

Traditional LED display screens have some obvious defects, especially in terms of protection and display effects. GOB LED modules effectively solve these pain points:

• Low protection level: Traditional LED display screens are completely exposed to the outside, lacking moisture-proof, waterproof, dust-proof and other protection measures, and are prone to dead lights and broken lights in humid environments. During transportation, it is also easy to drop lights and damage lamp beads. Especially for GOB LED display screens, this problem has been significantly improved.
• Great harm to the eyes: Long-term viewing of LED display screens may emit strong glare, causing eye fatigue and even retinal damage. Another problem is that the wavelength of blue light LEDs is shorter and the frequency is higher, and long-term viewing will damage the retina. The anti-frost and anti-blue light technology of GOB LED display screens can greatly reduce this risk.

Advantages of GOB technology in LED display screens

• Eight protections: GOB LED modules have excellent protection capabilities, including waterproof, moisture-proof, anti-collision, dust-proof, anti-corrosion, anti-blue light, anti-salt, and anti-static. It is particularly suitable for display occasions that require high reliability, such as outdoor advertising, stage rental, etc.
• Good display effect：The surface of the GOB LED display has a frosted effect, which increases the color contrast, realizes the conversion display from the viewpoint light source to the surface light source, and increases the viewing angle.

The process of GOB packaging technology

• Material selection and customization: The packaging materials of the GOB LED display must be customized according to the requirements of the GOB packaging process, and have high adhesion, high tensile strength, high temperature resistance, corrosion resistance and other characteristics. It must also have high transparency and yellowing resistance to ensure long-term stable display effects.
• Filling process: During the packaging process, the packaging material should fill all the gaps between the lamp beads and the PCB board tightly. Therefore, the surface of the GOB LED module after packaging should try to avoid defects such as bubbles, pinholes, and white spots to ensure its optical effect and stability.
• Thickness control: One of the keys to GOB LED display packaging is the uniformity of the glue layer. GOB packaging technology ensures that the thickness of the glue layer on the surface of the lamp beads is consistent, reduces tolerances, improves the accuracy of the product, and makes the display effect more uniform.
• Surface leveling: The surface after packaging should be kept flat to avoid undesirable phenomena such as bumps and ripples to ensure the appearance and display effect of the GOB LED module.
• Surface treatment: According to different product requirements, the surface of the GOB LED module can be matte, semi-gloss or mirrored to further optimize the display effect and visual experience.
• Restorability: The GOB LED module after GOB encapsulation has a certain degree of restorability. The encapsulation material can be removed and refilled under certain conditions to ensure the maintainability of the product in long-term use.

Application field of GOB encapsulation technology

With the maturity of GOB technology, through GOB encapsulation technology, LED display screens can achieve excellent performance and have a wide range of applications.

• Commercial advertising: High-definition and high-stability GOB LED modules are widely used in outdoor large-screen advertising, shopping mall LED display screens, etc.

• Stage rental: In concerts, exhibitions and other activities, the rental LED display screen using GOB encapsulation technology can withstand various complex environments and frequent disassembly and assembly requirements.
• Security monitoring: High reliability and stability make the LED display screen with GOB encapsulation technology an important equipment in the field of security monitoring.

• Smart home: With the development of smart home, GOB LED display screens are gradually used in home theaters, smart lighting and other fields.

Conclusion

GOB LED display, with its powerful protection ability and superior display effect, will become an important technological innovation in the LED display industry. With the continuous development of technology, GOB LED display will be more widely used in advertising stage, security and other fields, pushing the development of LED display technology to a new height.
