What is the difference between COB and LED light sources?
What is the difference between COB and LED light sources?
In general, the LED integrated light source is the use of COFB packaging technology to directly package the LED grain on the uniform temperature plate or copper substrate, forming a polycrystalline array, and the COB light source is a high-power integrated surface light source, is the LED light chip directly attached to the high reflective mirror metal substrate integrated surface light source technology.
The COB light source packages the low-power chip on the PCB board, and compared with the ordinary SMD low-power: higher brightness, lower thermal resistance, faster heat dissipation, smaller light decay, longer life.
Although some SMD low-power light source package to aluminum substrate is also called integrated LED, but this is not a COB light source, so in general, COB light source is an integrated LED light source, but the integrated LED light source is not all COB light source.

What is the difference between COB display and LED display?
- 1, COB display manufacturing steps less, no SMD packaging LED display (LED display) as complex, no patch, reflow and other processes, more reliable;
- 2, smaller spacing, more delicate picture: COB display has broken through the physical limit of SMD packaging process, completed the realization of smaller spacing, small spacing, more pixels in the unit display, fuller picture, more vivid colors;
- 3, the COB package LED display device is completely sealed on the PCB board, the device is not exposed, the protection level is stronger, direct touch with the hand, shake and no light phenomenon during transportation, after the product is put into use, the maintenance rate is almost 0;
- 4, surface light source light. Effectively inhibit the moire pattern, so that people can see for a long time at close range without eye damage;
- 5, faster heat dissipation, longer life: the heat is directly dispersed through the PCB board, the thermal resistance value is small, the heat dissipation is better, there is no heat accumulation, the life of electronic products will naturally become longer;
What is the connection between the COB display and the LED display?
COB display is the future of LED small pitch, is the first choice of 1.0mm below the pitch, there is no conflict between the two, but the ordinary LED display in the SMD packaging process can not meet the client more precise display requirements, can not achieve the realization of smaller spacing, so the birth of COB display.
