COB technology in LED display refers to Chip-On-Board packaging, where LED chips are directly mounted onto the substrate's surface. This method involves covering the silicon chip placement area with thermally conductive epoxy resin, securing the silicon chip onto the substrate through thermal treatment, and then establishing an electrical connection between the chip and the substrate using wire bonding.

Advantages of COB Technology in LED Display

·High Reliability: Directly mounting the chip onto the PCB reduces issues such as oxidation, mechanical fatigue, and thermal stress, improving product reliability.

·Low Cost: Eliminating the need for additional housings or brackets reduces production costs, especially in large-scale manufacturing.

·Compact Size and Lightweight: COB packaging allows for ultra-miniaturization, making it ideal for microelectronic devices.

·Wide Applicability: Suitable for various chip types, including ARM, DSP, and microcontrollers, meeting the demands of different fields.

·Customizability: Allows for personalized customization according to customer needs, adapting to various application scenarios and design requirements.

Applications of COB LED Displays

COB LED displays are used in a variety of applications due to their high pixel density, high brightness, and high contrast ratio. These include digital signage, commercial advertising, stage performances, command centers, indoor decoration, and medium to large conference rooms.

Comparison with Other Display Technologies

Compared to SMD (Surface Mounted Device) technology, COB technology offers higher brightness and even light dispersion with fewer shadows and contrasts. It also exhibits improved heat dispersion properties, leading to longer life and greater reliability.

In conclusion, COB technology in LED displays represents a significant advancement in terms of reliability, cost-effectiveness, and versatility, making it a preferred choice for various applications where performance and durability are crucial. (end)
