GOB LED Display Module

A GOB LED display module is an advanced LED technology designed to enhance the durability and performance of LED modules. The surface of the LED module is filled with a special transparent glue that forms a protective layer once it dries, which offers high resistance against water, dust, oxidation, and physical impact, making GOB LED modules particularly suitable for outdoor applications.

GOB LED display module

Overview

GOB LED display modules offer outstanding color consistency and wide viewing angles, ensuring vibrant and uniform display quality from nearly any perspective. With their high-level protection, these modules are particularly suited for easy transportation, minimizing the risk of damage during transit. This robust design significantly reduces the likelihood of LED lamp bead damage, making GOB modules both reliable and durable for various applications.

GOB technology addresses the limitations of traditional LED screen modules, especially in environments where the distance between LEDs is too small to apply conventional waterproofing methods. These type modules are widely used in GOB LED screen.

Why You Need GOB LED Module?

Traditional LED modules often suffer from vulnerabilities such as moisture, dust, and physical damage, which can lead to malfunctioning LEDs and reduced display quality. GOB LED modules, however, offer a robust solution to these issues through their advanced encapsulation technology.

High Protection

GOB LED modules provide protection against water, moisture, dust, impact, corrosion, blue light, salt spray, and static electricity. This makes them ideal for outdoor and harsh environments where traditional LED modules would fail.

Improved Durability

The protective layer formed by the glue on the LED surface significantly reduces the risk of LED damage during installation, transportation, and operation. This results in a longer lifespan for the LED display.

Enhanced Visual Performance

GOB technology transforms the LED surface from a point light source to a surface light source, offering more uniform brightness and clearer display quality.

Common Questions

GOB stands for “Glue On Board,” which refers to the process of applying a transparent glue on the surface of the LED module.

GOB and SMD LED modules are widely used in LED displays, however, they have some differences as follows:
FeatureGOB LED ModuleSMD LED Module
Protection LevelHigh protection (waterproof, dustproof, shock-resistant)Lower protection, more vulnerable to environmental factors
Viewing AngleWide viewing angles, up to 170° horizontally and verticallyTypically narrower viewing angles
DurabilityHighly durable, resistant to damage during transportLess durable, prone to damage during handling and transport
Visual QualityExcellent color consistency and reduced glareMay have more glare and less uniform color distribution
Anti-OxidationHigh resistance to oxidationMore susceptible to oxidation over time
Application EnvironmentsSuitable for harsh and varied environmentsBetter for controlled indoor settings
CostGenerally more expensive due to advanced protectionTypically less expensive, but with fewer protective features
MaintenanceLower maintenance needs due to enhanced protectionHigher maintenance requirements due to exposure risks
LED Damage RiskMinimal risk of LED lamp bead damageHigher risk of damage to LED lamp beads

COB (Glue On Board) LED module involves directly attaching LED chips onto a circuit board. it has some difference with GOB led modules as following:

FeatureGOB LED ModuleCOB LED Module
StructureGlue layer over LED chips for added protectionLED chips directly on board, smooth surface
ProtectionHigh protection: moisture, dust, shock, UV resistantModerate protection against environmental damage
Thermal ManagementEnhanced heat dissipation due to glue layerEfficient thermal management with chip-on-board setup
MaintenanceEasier, less costly maintenanceDifficult, costly due to complex repairs
Viewing ExperienceExcellent viewing angle and consistencyMay experience inconsistencies and granularity
ManufacturingMore complex production processSimpler production but higher potential manufacturing costs

The best viewing distance is between on the pixel pitch.

P5 mm5 m (16.4ft)10 to 15 m (32.8ft to 49.2ft)150m (492.1 ft)

Like the SMD LED module, controlling LED GOB modules also involves synchronous and asynchronous method:

  • Synchronous Control

  • Asynchronous Control

The price of GOB LED modules is generally higher than that of SMD LED modules due to the more complex manufacturing processes and advanced protective features/ Genearlly it need more $150 to $200 for one square meter.
