What is the difference between COB light source and LED?|LED Screen|LED Flexible Screen|LED Screen Manufacturers||China LED Screen Manufacturers

The LED integrated light source is using COFB encapsulation technology, LED grain is directly encapsulated in the homogeneous temperature plate or copper substrate to form a polycrystalline array, while the COB light source is a high-power integrated surface light source, is directly LED light emitting chip attached to the high reflectivity of the mirrored metal substrate of the integrated surface light source technology.

The cob light source will be small power chip encapsulated in the PCB board, and ordinary SMD small power compared to: higher brightness, thermal resistance is smaller, faster heat dissipation, less light decay, longer life.

Although some SMD small power light source encapsulated in the aluminum substrate is also called integrated LED, but this is not a COB light source, so in general, cob light source are integrated LED light source, but integrated LED light source is not always COB light source.
What is the difference between COB display and LED display?

1.cob display system work steps less, no SMD package led display (led display) as complex, no patch, reflow soldering and other processes, reliability is stronger;

2. smaller pitch, more delicate image: cob display breaks through the physical limits of SMD encapsulation process, completed the realization of a smaller pitch, small pitch, more pixels in the unit display, the image is fuller, more vivid colors;

3.cob encapsulated LED display will be completely sealed in the circuit board, the device is not exposed, the level of protection is stronger, with a direct hand touch, shaking, and no drop lights during transportation, the product is put into use, the maintenance rate is almost 0;

4. surface light source bright. Effective suppression of moiré, so that people can watch for a long time at close range without hurting their eyes; SUALEADER-02

5.faster heat dissipation, longer life: heat dissipated directly through the PCB board, thermal resistance value is small, better heat dissipation, there is no accumulation of heat, the life of electronic products will naturally be longer;

COB display is the future of LED small pitch, is 1.0mm pitch below the first choice, there is no conflict between the two, only ordinary LED display in the SMD encapsulation process can not meet the customer’s more sophisticated display requirements, not up to the realization of the smaller pitch, so the birth of COB display.
