In the LED display market, COB (Chip On Board) technology, as an advanced packaging technology, is gradually receiving attention. The COB LED display provides users with new choices with its unique packaging methods and performance characteristics. This article will explore the advantages and disadvantages of the COB LED display in detail to help you better understand this technology.
advantage
Excellent display effect
High -resolution: COB technology can easily achieve smaller point spacing, such as P0.9, P0.6, and even P0.4, making the display screen clearer and delicate. High -end conference rooms, etc. What is a COB LED display and what is COB LED technology?
High color reduction: The COB display uses the “surface” light source to light up, effectively suppress the Moor pattern, reduce the light refraction, the color is softer, the color reduction is high, especially suitable for application scenarios with high requirements for color.
Good luminous uniformity: The luminous uniformity of the COB display is good, the color and brightness uniformity is high, and the overall display effect is more consistent. It avoids the grainy and color unevenness of the traditional SMD display.
Strong stability
Well -encapsulated protection: The device of the COB display is closed on the PCB board, the surface is fixed, and the anti -collision ability is stronger. In the process of transportation, installation and use, there will be no adverse phenomena such as lighting and bad lights. From factory to product application, it can ensure that the product is not damaged.
Strong shell protection: The shell mask of the COB display is strong, the surface hardness reaches 4h, and the anti -bump ability is significantly enhanced. It is particularly suitable for application scenarios with higher environmental adaptability, such as outdoor advertising and security monitoring.
High heat dissipation efficiency: COB display has lower thermal resistance and high heat dissipation efficiency, which helps maintain stable operation for a long time and extend the service life of the display screen.
High cost benefits
Large -scale production cost: COB packaging eliminates a separate LED lamp bead structure, simplifies the packaging process, and can significantly reduce costs when large -scale production.
Low maintenance costs: The stability and protection of the COB display, low failure rate, low maintenance cost, especially suitable for occasions that require stable operation for a long time.
Appearance
Light and light design: The COB display is more light and light, easy to install and transport. At the same time, the appearance is more beautiful. It is particularly suitable for application scenarios that require high beauty requirements, such as high -end business exhibitions, art exhibitions, etc.
No seam: The COB display can achieve no seam display, the overall visual effect is more complete, especially suitable for the application of large -scale display walls.
shortcoming
High manufacturing cost
High R & D costs: The research and development cost of COB technology is high, and a large amount of funds and time need to be invested for technological research and development and equipment purchase.
Enterprise transformation costs: For traditional SMD packaging companies, transforming COB technology requires re -purchase equipment and training technicians, and the transformation cost is high. Take you to know the six differences between the SMD LED display and the COB LED display.
There are few manufacturers: There are few manufacturers who currently have COB technology, and the market competition is not sufficient, resulting in relatively high product prices.
The technical maturity is relatively low
Complex process: The COB packaging process is relatively complicated, the requirements for production equipment and technology are high, the production yield is low, which affects large -scale production and cost control.
Uniform standards: The standards of COB technology are not uniform, and the product compatibility of different manufacturers has poor compatibility, which brings inconvenience to users. Here are 7 differences and purchase guidelines for GOB and COB technology.
Low market acceptance
Low user awareness: COB technology is relatively new, low market acceptance, and users have doubts about their performance and reliability.
High price sensitivity: Some users are sensitive to price, and the high price of the COB display may affect its marketing.
Summarize
The COB LED display has gradually become a popular choice for the high -end LED display market with its excellent display effect, strong stability, high -cost benefits and aesthetic appearance. However, the shortcomings of high manufacturing costs, relatively low technology maturity, and low market acceptance cannot be ignored. With the continuous progress of technology and the gradual maturity of the market, the COB LED display is expected to obtain a wider range of applications in the future. If you are interested in the COB LED display, it is recommended to comprehensively consider its advantages and disadvantages when choosing, and choose the product that is most suitable for your needs.
