The Era of Technological Iteration: StongBell Leads the COB LED Display Revolution with Factory Direct Pricing and Unmatched Quality
2026-02-022
The tide of technological iteration is sweeping across the globe, and the technological landscape of the LED display industry is undergoing disruptive restructuring. As a powerful enterprise with 17 years of deep cultivation in the LED display sector, StongBell leverages its own production factory and integrated industrial chain layout, adhering to a factory direct sales model to deliver the lowest price for same-spec COB LED large screens nationwide. By eliminating all price markups from intermediate agents, we truly pass on the benefits to every customer. Backed by strong factory production capacity and core R&D strength, StongBell accurately captures the industry's transformative trends: the once widely used SMD indoor fine-pitch LED displays are accelerating their exit from the market, while COB packaging technology, with its absolute dual advantages in quality and price, has fully seized the discourse power of the LED large screen market and become the mainstream choice of the industry. Taking further advantage of its own factory, StongBell maximizes the high cost-performance ratio of COB technology, leading the display industry into a new era of seamless, ultra-high definition and cost-effective visual experience.
The iteration of LED display technology has always advanced around the core user demands of better quality and more affordable prices. In the past, SMD indoor fine-pitch LED displays occupied a certain market share due to their low entry threshold; however, with the increasing maturity and large-scale application of COB technology, coupled with the continuous release of production capacity and extreme cost compression at StongBell's own factory, the inherent shortcomings of SMD indoor fine-pitch displays have been magnified infinitely. Their replacement by COB has become an irreversible industry trend, and the replacement process is accelerating continuously. This trend is clearly evidenced by market data: in the first quarter of 2025, the sales market share of SMD indoor fine-pitch displays dropped by 2 percentage points year-on-year, while that of COB products surged by 2.2 percentage points year-on-year. With the continuous expansion of market share, the trend of industry reshuffle has become increasingly evident.
Unsurpassed Quality: COB Outperforms SMD in All Aspects, Exposing the Latter's Critical Shortcomings
In terms of the core quality experience of LED large screens, COB technology has achieved a dimension-level leap compared with SMD indoor fine-pitch displays, fundamentally solving the long-standing industry pain points of the latter—a fact that dooms SMD indoor fine-pitch displays to gradual replacement by COB. COB adopts a packaging method that involves direct bonding and wire bonding of bare chips to PCB substrates, followed by resin encapsulation, eliminating the independent packaging process of individual lamp beads. This integrated design has brought a qualitative leap in display effect, reliability and protective performance. Relying on its own factory, StongBell standardizes and scales the production of this high-quality packaging technology. While ensuring quality and production capacity, we achieve the lowest nationwide price for same-spec products through the factory direct sales model, further accelerating the COB replacement process and completely breaking the industry barrier that "superior quality must come with a high price".
In terms of display effect, COB is a surface light source with excellent optical diffusion and color mixing effects, which can completely eliminate the common problems of SMD indoor fine-pitch displays such as pinpoint light, glare, ghosting and the "caterpillar effect". It features a wider and flexibly adjustable viewing angle, with seamless image connection and uniform, delicate colors. Even when viewed at close range, it delivers an ultra-high definition and transparent visual experience—an advantage that the point light source design of SMD indoor fine-pitch displays can never match. The advantages of COB are particularly prominent in high-end scenarios with stringent requirements for display consistency, such as high-end conferences, command and dispatch centers, and XR virtual production. Backed by the R&D and production strength of its own factory, StongBell can customize COB LED large screens according to the needs of different scenarios, with full-process factory direct supply, adhering to both the bottom line of quality and the commitment of the lowest nationwide price.
In terms of reliability and protective performance, the surface of COB lamp points is spherical, raised, smooth and hard, with excellent anti-collision, compression resistance, dustproof and moisture-proof capabilities. Its failure rate is an order of magnitude lower than that of SMD indoor fine-pitch displays, with a significantly improved mean time between failures (MTBF) and almost no risk of dead lamp beads. In contrast, SMD indoor fine-pitch displays adopt surface-mount packaging of individual lamp beads; the gaps between lamp beads are prone to dust accumulation and damage from collisions, leading to frequent dead lamp beads and color shift after long-term use, and exorbitant maintenance costs. The COB LED large screens produced at StongBell's own factory are also equipped with self-developed core technologies, with a product qualification rate of up to 99.2%, further reducing later maintenance costs. Combined with the advantage of the lowest nationwide price, our products deliver a comprehensive cost-performance ratio far exceeding that of SMD indoor fine-pitch displays.
Price Reversal + Factory Direct Supply: StongBell's COB Products Boast the Lowest Nationwide Price, Leaving SMD Indoor Fine-Pitch Displays with No Competitive Edge
If quality advantages lay the foundation for the replacement of SMD by COB, StongBell's factory direct sales model and commitment to the lowest nationwide price have completely shattered the last line of defense of SMD indoor fine-pitch displays, accelerating their replacement by COB. In the past, COB products were priced higher than SMD indoor fine-pitch displays due to high technical thresholds and limited production capacity, making some users hesitant to purchase. However, with the continuous expansion of industry production capacity (the global planned monthly production capacity of COB packaging will exceed 80,000 square meters in 2025) and the continuous optimization of production processes, coupled with the advantages of large-scale production and integrated industrial chain at StongBell's own factory, the cost of COB products has dropped significantly—the average price of COB packaging products plummeted by 31.4% year-on-year in the first quarter of 2025. Today, relying on the advantage of factory direct supply, StongBell's COB products are not only priced lower than the industry average but also achieve the lowest nationwide price for same-spec products, completely depriving SMD indoor fine-pitch displays of their price advantage. The gap in cost-performance ratio is constantly widening, further driving their gradual replacement by COB.
From the perspective of cost composition, the COB packaging process is more concise, eliminating the spectral and color sorting, tape packaging, reflow soldering and other processes required for SMD indoor fine-pitch displays, inherently boasting cost advantages. StongBell owns its own production factory and has a vertically integrated supply chain, which allows us to cooperate directly with raw material manufacturers, eliminate all price markups from intermediate agents and distributors, and further compress labor and material costs relying on large-scale production—this is the core strength that enables the enterprise to achieve the lowest nationwide price. Taking large LED large screen projects as an example, the initial procurement cost of SMD indoor fine-pitch displays may seem low, but frequent replacement of damaged lamp beads and regular maintenance are required in the later stage, resulting in an annual maintenance cost far higher than that of COB products. In contrast, StongBell's COB large screens require almost no frequent maintenance due to their high reliability; combined with the lowest nationwide procurement price, the comprehensive cost is 20%-30% lower than that of SMD indoor fine-pitch displays in the long run, showcasing an extremely prominent advantage.
Industry Consensus: The Elimination of SMD Indoor Fine-Pitch Displays Is Inevitable, and COB Leads the Future Trend
In the future, with the continuous upgrading of COB technology and further release of production capacity, its price advantage will become more prominent, and the market space of SMD indoor fine-pitch displays will continue to shrink, gradually being fully replaced by COB and eventually completely exiting the LED large screen market—this replacement trend has become a consensus across the entire industry. StongBell will also continue to increase investment in technological R&D, relying on the production advantages of its own factory to promote the innovation and application of COB technology, continuously optimize the production process and compress product costs, and continue to abide by the commitment of the lowest nationwide price for same-spec products. We will launch more high-quality and cost-effective COB LED large screen products, further accelerate the replacement process of SMD indoor fine-pitch displays, lead the high-quality development of the LED display industry, and bring users a better display experience. At the same time, we will repay the trust and support of customers nationwide with more competitive prices and more comprehensive services。
