The innovation path of COB technology: from budding to prosperity.

With the rapid development of electronic display technology, COB (Chip-On-Board) technology is gradually becoming the new favorite of the LED display industry with its unique advantages. From the early germination of technology to the widespread application today, the development of COB technology has not only witnessed the progress of electronic manufacturing technology, but also foreshadowed the future development direction of display technology.

Technology Origin and Initial Development

The origin of COB technology can be traced back to the field of semiconductor manufacturing, and its initial application was mainly concentrated on the packaging of high-density integrated circuits. With the rise of LED display technology, COB technology has gradually entered the field of LED display with its high-density integration and high reliability, and has quickly been recognized by the market. This transformation has not only promoted the progress of LED display technology, but also opened up a new path for the development of COB technology itself.

Technical characteristics and advantages are prominent

The core advantage of COB technology is that it directly encapsulates the LED chip on the PCB board, realizing the close connection between the chip and the substrate. This packaging method not only simplifies the production process, but also significantly improves the reliability and stability of the product. Specifically, COB technology has the following significant features:

• Lightweight and thin: Since the shell and bracket in the traditional package are omitted, COB products become lighter and thinner, which is convenient for flexible application in various scenarios.
• Wide viewing angle: The shallow well spherical light-emitting design is adopted, and the viewing angle can reach more than 175 degrees, close to 180 degrees, providing a wider viewing angle.
• Bendability: The unique packaging structure enables the COB module to be easily bent, which is suitable for making special-shaped screens such as curved screens and circular screens.

Technological Innovation & Market Application

In recent years, as LED display products have developed towards higher pixel density and smaller pixel pitch, COB technology has become the direction of technological change for small-pitch LED displays with its unique advantages. Major LED display manufacturers have increased their R&D investment and launched a series of innovative products based on COB technology. For example, the green ultra-high-definition flip-chip COB high-end energy-saving cold screen of Xida Electronics and the world's first outdoor COB screen of Zhouming Technology have not only enriched the market choices, but also promoted the rapid development of COB technology.

In terms of market application, COB technology has been favored by all walks of life for its excellent performance and wide application scenarios. In the advertising and media industry, the high brightness and high contrast of COB display screens make it the preferred choice for outdoor advertising; in the field of transportation and security, the high reliability and stable performance of COB display screens ensure the real-time and accurate transmission of information; in the field of education and training, the high-definition display and delicate picture quality of COB display screens provide strong support for teaching; in the sports and entertainment industry, the large size and high brightness of COB display screens bring immersive viewing and entertainment experience to the audience.
