With the rapid development of science and technology, LED display screens have been widely used in various occasions and have become an important medium for information dissemination and display.
Among the many technologies of LED display screens, COB displays have gradually emerged with their unique advantages and become an emerging star in the LED display industry.
COB display screen packaging technology
COB display, that is, chip-direct packaging display, is a kind of LED chip that is directly packaged on the PCB board, and a fully sealed structure of pixels is achieved through a specific packaging process. This packaging method makes the COB display have excellent stability and image quality, bringing revolutionary changes to the LED display industry.
COB display features
First of all, the durability and high protection of COB display is one of its distinctive features. Take CHIFE’s P1.56, P1.25, P0.93, and P0.78 series COB small-pitch displays as an example. By packaging the pixels on the PCB board, the device is fully sealed, with a smooth and hard surface and a strong protection level. This design makes the CHIFE COB display anti-impact, anti-bump, anti-pressure, and truly waterproof, moisture-proof, dust-proof, and anti-oxidation. In practical applications, whether installed indoors or outdoors, CHIFE COB displays can perform well and operate stably for a long time, reducing failures and maintenance costs caused by environmental factors.
COB display screen quality and application
Secondly, the CHIFE COB display also has significant advantages in image quality. Due to the COB packaging process, the pixel spacing is smaller and there are more pixels per unit area, so the display content is richer and the picture is more delicate.
This excellent image quality also makes CHIFE COB display screens widely used in high-end occasions such as multi-functional conference rooms, studios, military dispatching and command, power dispatching, aerospace monitoring and other fields.
COB display packaging process
CHIFE COB display also has advantages in process flow. Traditional LED displays require LED chips to be welded one by one on the PCB. This method is not only cumbersome, but also prone to problems during the welding process, causing the lamp beads to fall or be damaged.
The CHIFE COB series products use a packaging method that directly integrates LED chips on the PCB board, which simplifies the packaging process and improves production efficiency. At the same time, the stability of the COB display has also been significantly improved because the connection between the LED chip and the PCB board is more stable.
It is worth mentioning that as COB technology continues to mature and costs decrease, its share in the LED display market is gradually increasing. According to relevant data, in China’s domestic small-pitch LED (below P2.5) market in 2024, the sales volume of COB products will increase by more than 50%, showing its strong market competitiveness.
This growth is not only due to the advantages of COB display screens in terms of image quality and stability, but also due to the cost reduction of COB technology, making it more affordable and accepted by more users.
With the continuous advancement of technology and the continuous expansion of the market, it is believed that CHIFE COB display will continue to exert its advantages in the future and provide better and more stable display solutions for more fields.
