Quick answer: GOB (Glue on Board) adds a transparent protective glue layer over standard SMD LED modules. It protects LEDs from impact, moisture, dust and static, reducing dead pixels in rental, touchable and floor LED screens, while keeping SMD’s cost and pixel pitch options.

GOB Technology

GOB (Glue On Board) technology adds a transparent protective layer over traditional LED modules.

The goal is mainly to improve:

impact resistance
moisture protection
dust protection
keandalan

Why GOB Became Popular in Rental Projects

Rental LED displays face much higher physical stress than fixed installations.

During transportation and installation, LED modules are constantly exposed to:

collisions
getaran
repeated assembly
outdoor humidity

GOB protection helps reduce lamp damage risks significantly.

Why Some Customers Prefer GOB for Indoor Projects

In some indoor commercial environments, customers may accidentally touch the display surface.

This is common in:

pusat perbelanjaan
museum
ruang pamer
education projects

GOB protection helps improve screen durability in these environments.

DDW Engineer Notes: GOB LED display technology

GOB is not necessarily intended to replace COB.

In many projects, GOB serves more as a practical protection enhancement for traditional SMD products.

This is especially useful in:

panggung sewaan
high-traffic environments
projects with frequent transportation

FAQ

What is the difference between GOB and COB?

GOB coats finished SMD modules with protective glue, while COB mounts bare chips directly on the board and seals them. COB supports finer pitches; GOB upgrades SMD protection.

Does GOB affect LED display image quality?

Quality GOB coatings are highly transparent and can improve contrast; poor coatings may reduce brightness or cause color shift.

Why do rental LED screens use GOB?

Rental screens are assembled and moved often. GOB protects LEDs from knocks during setup and transport, reducing repair costs.
