Cob package LED display is a display made of LED devices based on chip bonding (Cob) technology. Cob packaging fixes the LED chip on the radiator and connects it to the display module through adhesive material. The radiator dissipates the heat generated by the chip to extend the working time of the LED chip and improve the performance of the LED. Cob package LED display has the advantages of high stability, high brightness and high contrast, so it is widely used in fields such as commercial advertising and outdoor display.

The COB packaging technology of the LED display screen refers to the chip-on-board packaging technology. It directly integrates the LED light-emitting chip on the PCB board, instead of first packaging it into lamp beads and then welding it like traditional packaging technology. This technology eliminates the bracket and the solder paste connection to the PCB through reflow, thereby increasing the protection capability and avoiding LED failures caused by external collisions.
COB packaging technology can also increase the brightness of the LED display, because the packaging technology uses a combination of polysilicon and organic silicon. This material can increase the brightness of the LED display, making the display have higher contrast and lower power consumption. and longer lifespan.
In general, COB packaging technology is of great significance to the development of LED displays. It can improve the brightness, reliability and performance of the display, making it more suitable for high-end application scenarios. For more information about COB packaging technology, it is recommended to visit relevant technical forums or consult LED display manufacturers.

COB is a packaging technology that fixes LED light-emitting chips on a PCB substrate and then attaches glue to the whole. It has the characteristics of moisture-proof, anti-static and anti-collision, which greatly reduces the phenomenon of dead light caterpillars. It is the most suitable technical route in the mini era.
