Speaking of led display screens, this is certainly not unfamiliar to everyone, because led display screens are too common, whether it is indoors or outdoors, it is often accompanied by the figure of led display screens wherever you go. However, when it comes to LED display cob technology, this may be a bit confusing. What is a cob led display?
As far as the current situation is concerned, we generally say that the led display is based on SMD technology, which is often referred to as surface mount. However, with the development of small LED spacing, SMD has reached the physical limit, and there is no way to make it smaller. The spacing is deep digging, so there is a cob encapsulated led display, which is a cob display.

The led display cob technology refers to the led display completed by the cob packaging method. Cob packaging: directly encapsulate the light-emitting chip on the PCB board to realize the real and complete sealing of the module, the device is not exposed, and the screen is smooth and hard.

Advantages of cob display:
1. Anti-collision and anti-collision: the surface is cured with epoxy resin, and the device is sealed on the PCB board, not exposed, not shaking off the lamp, and not damaged during transportation;
2. Strong heat dissipation ability: the heat is quickly dissipated directly through the PCB board, the thermal resistance is small, and the heat dissipation is stronger;
3. Smaller pitch and better picture quality: COB display does not have SMD packaged led display, which requires multiple processes and needs to make light-emitting chips into lamps, which limits the smaller pitch to a certain extent. The cob display does not, there is no physical barrier between the light-emitting chips, there are more display pixels in the unit, the picture is clearer, the display is fuller, the color is more abundant, and the color is more delicate;
4. "Surface light source" emits light and effectively suppresses moiré. It is a high-quality choice for important occasions, such as high-end conference rooms, studios, and central occasions.
