Generally speaking, LED integrated light sources are used to use COFB packaging technology to directly package LED grains on a balance plate or copper -based plate to form a polycrystalline array. The COB light source is a high -power integrated surface light source. Integrated surface light source technology on the high reflection mirror metal substrate.
COB light source encapsulates the small power chip on the PCB board. Compared with ordinary SMD power: higher brightness, smaller thermal resistance, faster heat dissipation, smaller light failure, and longer life.
Although some of the SMD small power light sources are encapsulated to the aluminum substrate, which is also called integrated LED, this is not a COB light source. Therefore, the COB light source is integrated with LED light sources, but the integrated LED light source is not all COB light sources.
What is the difference between COB display and LED display?
1. The COB display screen has few steps, and there is no SMD packaging LED display (LED display). It has no patch and return welding and other processes.
2. Small spacing and more delicate screens: the COB display breaks through the physical limit of the SMD packaging process, completes the realization of smaller pitch, has a small spacing, has more pixels in the unit, the picture is fuller, and the color is more bright;
3. COB packaging LED display completely seal the device on the PCB board, the device is not exposed, the protection level is stronger, and the lights are directly touching, shake, and no lights during transportation. After the product is put into use, the maintenance rate is almost 0;
4. Facial light sources glow. Effectively suppress the Moore pattern, let people watch it for a long time and not hurt their eyes;
5, faster heat dissipation, longer life: calories are directly dispersed through the PCB board, the heat resistance value is small, the heat dissipation is better, without the accumulation of heat, the life of electronic products will naturally become longer;
What is the COB display and LED display?
The COB display is the future of the small spacing of LED. It is the first choice of a spacing below 1.0mm. There is no conflict between the two. The realization of the spacing is born, so the COB display is born.
