In the field of consumer electronics, the application cases of COB (Chip-on-Board) technology mainly include the following aspects:
Apple MacBook Pro: Apple uses Mini LED backlight technology in the MacBook Pro released in 2024, which is also called a form of COB technology. Mini LED backlight technology achieves higher brightness and better color performance by integrating multiple small LED lamp beads in one backlight unit.
Monitors and TVs: COB technology is also widely used in the fields of monitors and TVs. For example, the 75-inch The Wall Micro LED display displayed by Samsung at CES 2024 uses COB technology, providing extremely high contrast and color performance.
Mobile phones: Although COB technology has not yet been widely adopted in the mobile phone field, COB technology has great potential for application in future mobile phone displays. COB technology can provide higher pixel density and smaller dot pitch, thereby improving the display effect. With the advancement of technology and the reduction of costs, the application of COB technology in mobile phone displays may gradually increase.
Definition and advantages of COB technology
Definition of COB technology: COB (Chip-on-Board) technology is a packaging method that directly integrates LED chips on printed circuit boards (PCBs), eliminating the production and welding steps of lamp beads in traditional packaging. This technology simplifies the production process and improves the overall performance of LED displays.
Advantages of COB technology:
High resolution and clarity: COB technology achieves smaller dot pitch and higher pixel density by directly adhering LED chips to PCB boards, providing more delicate and clear picture quality.
Good heat dissipation performance: Since the chip is directly adhered to the PCB board, the heat dissipation performance is significantly improved.
High reliability: COB technology reduces the number of components, reduces the failure rate, and improves the reliability and service life of the product.
