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

1. About GOB display
GOB technology is an improved iterative technology based on SMD packaging technology. It is an 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 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 the GOB display is that it is highly protective and does not cause harmful effects on heat dissipation and brightness, thus reducing the damage rate of the LED lamp bead, making the screen display more stable, and extending 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
COB display adopts chip packaging technology, and the chip is welded directly to the display substrate. As a result, it has higher integration and smaller size. The COB display can achieve a more compact design and a thinner appearance, which is suitable for scenes with certain requirements for display size and weight, especially P1.2 and below pixel pitch. 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 display and COB display is mainly the difference in process. 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.

Which has the advantage, COB or GOB?
There is no standard for which GOB display and COB display are good, and they each have their own advantages to choose which is better according to specific needs, installation environment and other comprehensive factors to consider. For example, in the indoor 1.2mm spacing and below, COB is obviously more advantageous, if it is in the field of P1.5mm and outdoor ultra-high-definition display, GOB will be a good choice, the cost is lower.
