GOB display screen or COB display screen,which is better?

With the rapid development of LED display, the traditional SMD technology has been unable to meet the needs of some scenarios. Therefore, some manufacturers choose to adopt COB technology layout, while others continue to improve SMD technology. So, which is better, GOB display screen or COB display screen?Shenzhen weigu will give you an in-depth understanding of:

1.About GOB display screen

GOB technology is an improved iterative technology based on SMD packaging technology.It is a packaging technology designed to solve the protection problem of LED lamp beads. The technology uses advanced transparent materials to encapsulate the PCB substrate and LED package unit, forming an effective protective layer. It can be seen as adding a layer of protection before the original LED module. In this way, the GOB LED display has waterproof, moisture-proof, anti-impact, anti-bump, anti-static and other functions, so it is suitable for use in outdoor environments and bad weather conditions.

The advantage of GOB display is that it has a high degree of protection, and will not cause harmful effects on heat dissipation and brightness, so it reduces the damage rate of LED lamp beads, makes the screen body display more stable, and extends the service life. Through the processing of GOB process, the pixel particle on the surface of the original lamp board has been transformed into the whole flat lamp board, and the transformation from point light source to surface light source has been realized. This makes the product glow more uniform and the display effect more clear and transparent.

2. About COB display screen

The COB display uses chip packaging technology to solder the chip directly on the display substrate. As a result, it has higher integration and smaller size.The COB LED display can achieve a more compact design and a thinner appearance, which is suitable for scenarios with certain requirements on the size and weight of the display, especially the pixel pitch of P1.2 and below. In addition, COB technology provides better heat dissipation performance, and has high reliability and stability, so it is widely used in some industrial fields that require stable operation for a long time.

The advantage of the COB display is that it uses a PCB board about 1mm thick and weighs only 40% of the original product. The surface of the lamp point is raised into a surface, smooth and hard, resistant to impact and wear. This greatly extends the life of the display, and there is rarely a dead lamp phenomenon. In addition, the surface of the lamp point presents a raised sphere, smooth and hard, and also has the characteristics of impact resistance and wear resistance. If there is a bad spot, it can be repaired point by point. In addition, the COB display has no mask and can be cleaned using water or cloth, which is very convenient.

The difference between GOB and COB displays is mainly due to differences in workmanship. Although the surface of the COB package is flat, its protection performance is better than that of the traditional SMD package. The GOB package increases the gluing process on the screen surface, improves the stability of the LED lamp bead, and greatly reduces the possibility of dropping the lamp, so it has stronger stability.

3.Which has more advantages,COB or GOB?

There is no standard for GOB display screen and COB display screen, they have their own advantages to choose which is better according to the specific needs, installation environment and other comprehensive factors to consider.For example, in the application field of small pitch products, 1.2mm pitch and below, COB display technology can achieve, obviously more advantages; But at 1.5mm to 2.5mm, GOB has more cost advantages.
