Speaking of LED displays, this one is definitely not unfamiliar to everyone, because LED displays are too common, whether indoors or outdoors, they are often accompanied by LED displays wherever they 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, the LED display we generally say 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 go smaller. The spacing is deep, so there is a COB packaged LED display, which is a COB display.

LED display COB technology refers to the LED display completed by COB packaging. COB packaging: directly encapsulate the light-emitting chip on the PCB board, so that the module is truly completely sealed, the device is not exposed, and the screen surface is smooth and hard.

The advantages of COB display:

1. Anti-collision and anti-collision: the surface is cured with epoxy resin, the device is sealed on the PCB board, not exposed, the light will not be shaken, and the collision will not be damaged during transportation;

2. Strong heat dissipation capacity: heat is dissipated directly through the PCB board quickly, the thermal resistance value is small, and the heat dissipation is stronger;

3. Smaller pitch and better picture quality: COB display is not like 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, and There is no cob display, there is no physical barrier between the light-emitting chips, more pixels are displayed in the unit, the picture is clearer, the display is fuller, the color is more abundant and more delicate;

4. The "surface light source" emits light, effectively suppressing moiré, and is a high-quality choice for important occasions, such as high-end conference rooms, studios, and central occasions.
