Technological innovation drives performance improvement and cost optimization
Breakthrough in Display Performance: COB (Chip on Board) technology achieves high-density integration by directly packaging chips on substrates, significantly improving display performance. Its fully enclosed structure solves the problem of LED crystal failure due to environmental interference, with an average annual maintenance cost of only 43% of traditional SMD products. At the same time, the popularity of COB technology supporting smaller pixel spacing, such as P0.3-P.7mm spacing, makes the display more delicate and meets the requirements of ultra high definition display.
Continuous cost reduction: With the improvement of upstream chip efficiency, localization of equipment, and yield rate (comprehensive yield rate of about 90%), the production cost of COB light strips has been continuously optimized. According to data from multiple sources, the average price of COB products in the first quarter of 2025 decreased by 31.4% year-on-year to 17200 yuan/square meter, significantly lower than the premium level of traditional SMD products, driving a surge of 49.1% in shipment area. The decrease in cost will gradually promote the application of COB light strips in more fields.
Diversified expansion of application scenarios

Display market dominance: COB light strips occupy a core position in command and control centers, conference rooms, commercial displays, and other scenarios. For example, in the command and control center, COB display screens have become a solution for information display due to their high reliability, high contrast, and seamless splicing characteristics.
The rise of emerging markets: With the accelerated development of fields such as virtual photography and smart education, the demand for COB light strips has surged. The single project area exceeds 500 square meters (P1.2 specification), promoting the implementation of area application. In addition, in terms of LED all-in-one machines, although the penetration rate of COB is only 5% -8%, its surface illumination and pressure resistance advantages meet the interactive needs, and the procurement proportion of the education industry reaches 52.3%.
Breakthrough in outdoor and rental markets: COB technology is gradually challenging SMD's traditional advantages in the outdoor market. For example, Hongli Display's 3000nit high brightness outdoor COB product solves the problem of outdoor environmental adaptability and provides possibilities for the application of COB light strips in outdoor advertising, stage rental and other fields.
