The Korean COB screen manufacturing solution relies on advanced COB packaging technology to achieve direct integration of LED chips and PCB boards, significantly improving the brightness, contrast and uniformity of the display screen, while simplifying the production process and reducing costs.
This technology is widely used in commercial advertising, stage performances, stadiums and other fields, bringing users clear and bright visual effects.
Introduction
In the LED display industry, COB (Chip on Board) technology is gradually emerging, and its unique advantages and wide application fields make it the future trend of the LED display industry.
As one of the important countries in LED display manufacturing, South Korea has a significant leading position in the research and development and application of COB technology.
This article will introduce the Korean COB screen manufacturing solution in detail, and comprehensively explain the advantages of COB technology, manufacturing process flow, application fields and South Korea’s leading position in this field.
Advantages of COB technology
COB technology is a packaging technology that integrates multiple LED chips on the same chip. By directly connecting multiple LED chips to the PCB board, it effectively reduces the packaging volume and luminous space, and improves the light output efficiency. Its advantages are mainly reflected in the following aspects:
- Good thermal conductivity: Since multiple LED chips are closely arranged on the same chip, COB technology is conducive to heat dissipation, reduces the operating temperature of the LED display, and increases the service life of the LED.
- High brightness and high contrast: COB technology can achieve high-density arrangement of LED chips, so that the LED display can obtain higher brightness and contrast, and provide better visual effects.
- Uniform light distribution: COB technology can achieve close packaging of multiple LED chips, eliminate the gaps between multiple LEDs, make the light evenly distributed, and reduce light spots and color differences.
- Display consistency: Since COB technology connects multiple LED chips on the same chip, the LED display has good consistency in display effects, avoiding optical differences between different chips.
Korea COB screen manufacturing process
Korea COB screen manufacturing process mainly includes the following steps:
- Chip selection and layout: Select the appropriate LED chip according to the requirements of the display, and place it precisely on the printed circuit board (PCB) to ensure that each pixel can emit light evenly.
- Packaging process: The selected LED chip is fixed on the PCB board through the crystal bonding process, and gold wire is used for electrical connection. Next, the chip is packaged, usually with transparent or translucent epoxy resin material to protect the chip and provide the necessary optical effect.
- Testing and screening: After the packaging is completed, the photoelectric parameters of each LED unit are tested to ensure that it meets the standard requirements. Unqualified units will be eliminated to ensure the quality of the final product.
- Integration and modularization: The packaged LED units are integrated into the display module through high-precision equipment. This step requires extremely high precision to ensure seamless docking between each module and the flatness of the entire screen.
During the manufacturing process, Korean companies focus on introducing advanced production equipment and process technologies, such as efficient crystal bonding technology, automated packaging equipment, etc., to improve production efficiency and product quality. At the same time, Korean companies also focus on research and development and innovation, and continuously promote the innovation and development of COB technology.
Application areas of COB technology
The advantages of COB technology make it widely used in the LED display industry. At present, COB technology is mainly used in the following fields:
