What's the Difference Between COB and GOB LED Displays?

2024-12-25

Hi, everyone! Today, let's talk about COB and GOB LED display and see what their differences are.

一、Different processes

COB led display process

For COB led display, LED chips are directly packaged on the circuit board. It's like finding a super sturdy home for the chips. The chips and the circuit board are closely connected, and there will be no easily occurrence of poor contact.

After packaging, the surface of the display will be specially treated. In this way, it's like putting on a "protective suit", which is waterproof, dustproof, and crashproof. It can even work normally in water.

Making COB displays requires very precise equipment and superb technology. First, package the chips on the circuit board through some complex processes, and then perform optical processing and testing to ensure excellent quality.

GOB LED display process

For GOB led display, a layer of special glue is applied on the surface of the LED lamp beads for packaging. This layer of glue is like a "protective cover", which can be waterproof, dustproof, and moistureproof, so that the lamp beads are not affected by the external environment.

With this layer of glue, the protection level of the display is also greatly improved, and it can display normally in relatively harsh environments.

Compared with COB led display, the production process of GOB is simpler. It does not require such high-precision equipment, so the cost is relatively low.

二、Different performance characteristics

Protection performance

COB led display have extremely powerful protection performance! They are waterproof, dustproof, and crashproof, and can even be used underwater. Moreover, the heat dissipation is also good, and the display has a longer lifespan.

GOB led display also have good waterproof, dustproof, and moistureproof performance, but it is still slightly inferior to COB. If subjected to a strong impact, the lamp beads may fall off.

Display effect

The pixel pitch of COB led display can be made very small, so the resolution is high and the display effect is particularly excellent! The images and videos are very delicate and realistic, and the colors are more vivid.

The display effect of GOB led display is also okay, but it is slightly inferior to COB in terms of resolution and color. However, if the display effect requirements are not particularly high, GOB is completely sufficient.

Reliability

Due to the special packaging method, COB led display have high reliability. The connection between the chips and the circuit board is tight, and there is not easy to be failures. Good heat dissipation also makes it more stable.

The reliability of GOB led display is also good, but the glue may age and crack, and there may be some small problems in long-term use.

三、Different application scenarios

COB led display application scenarios

High-end indoor display: In places like conference rooms, exhibition halls, and command centers, where high-definition images and videos are required, COB led display are the best choice.

Outdoor advertising: COB led display have good protection and can work in various harsh outdoor environments. They are very suitable for billboards and light boxes.

Stage performances: On the stage, high-brightness and vividly colored displays are needed to create a shocking effect. COB led display are extremely suitable.

GOB LED display application scenarios

Ordinary indoor display: In indoor places such as shopping malls, supermarkets, and schools that do not have particularly high requirements for display effects, GOB led display are low in price and can meet basic display needs.

Outdoor small-pitch display: In the field of outdoor small-pitch displays, GOB led display also have a place. With good protection and relatively low price, it can be considered for projects sensitive to cost.

四、conclution

In short, COB and GOB LED led display have their own advantages and disadvantages. You can choose according to your actual needs and budget. I hope this article can give you a clearer understanding of them!
