As an important part of the commercial display field, the LED display industry has a remarkable speed of technological innovation. At present, there are four mainstream packaging technologies – SMD, COB, GOB, and MIP are competing to try to occupy a place in the market. As a manufacturer in the commercial display industry, we must not only have an in-depth understanding of these four major packaging technologies, but also be able to understand market trends in order to seize the initiative in future competition.
1,The four major technologies show their magical powers
SMD (Surface Mounted Device) still demonstrates its immortal legendary style with its stable posture.
① Technical principle: SMD technology is a process of directly mounting LED lamp beads on PCB boards. Through welding and other methods, the LED chip is closely combined with the circuit board to form a stable electrical connection.
② Features and advantages: SMD technology is mature and stable, the production process is simple, and it is easy to mass produce. At the same time, its cost is relatively low, which makes SMD display screens have a greater advantage in price. In addition, the brightness, contrast and color performance of SMD display screens are also relatively good.
③Application limitations: Although SMD technology has many advantages, its picture quality and stability may be affected in the field of small pitch and micro pitch display. In addition, the protection performance of SMD display screen is relatively weak and is not suitable for harsh outdoor environments.
④Market positioning: SMD technology is mainly used in the mid-to-low-end market and general commercial display projects, such as billboards, indoor display screens, etc. Its cost-effectiveness advantage makes SMD display screens have a large market share in these fields.
COB (Chip On Board) a bright newcomer in the field, leading the industry towards a brilliant future.
①Technical principle: COB technology is a process of directly encapsulating LED chips on substrates. Through special packaging materials and technologies, the LED chips are closely combined with the substrate to form high-density pixels.
②Feature advantages: COB technology has the characteristics of small pixel pitch, high picture quality, high stability and high protection performance. Its picture quality performance is particularly outstanding, and it can present more delicate and realistic image effects. In addition, the protection performance of COB display screens is also strong and can adapt to a variety of harsh environments.
③Application limitations: The cost of COB technology is relatively high, and the technical threshold is high. Therefore, it is mainly used in high-end markets and professional display fields, such as command centers, monitoring centers, high-end conference rooms, etc. In addition, due to the particularity of COB technology, its maintenance and replacement costs are also relatively high.
③ Market positioning: COB technology has become a new technology in the industry with its excellent performance and high-end market positioning. In the high-end market and professional display field, COB display screens have a large market share and competitive advantages.
GOB (Glue On Board) is the tough guardian of the outdoor world, fearless of wind and rain, standing firm.
① Technical principle: GOB technology is a process of injecting special colloids around LED chips. Through the encapsulation and protection of the colloid, the waterproof, dustproof and shockproof performance of the LED display screen is improved.
② Features and advantages: GOB technology has a special colloid encapsulation structure, which makes the display screen have higher stability and protection performance. Its waterproof, dustproof and shockproof performance are particularly outstanding, and it can adapt to harsh outdoor environments. In addition, the brightness of the GOB display screen is also relatively high, and it can present clear image effects in outdoor environments.
③ Application limitations: The application scenarios of GOB technology are relatively limited, mainly concentrated in the outdoor display market. Due to its high requirements for environmental and climatic conditions, its application in the field of indoor display is relatively small.
④ Market positioning: GOB technology has become a leader in the outdoor display market with its unique protection performance and stability. In specific scenarios such as outdoor advertising and sports events, GOB display screens have a large market share and competitive advantages.
MIP (Mini/Micro LED in Package) is a smart little expert in cross-border integration, interpreting infinite possibilities.
① Technical principle: MIP technology is a process of encapsulating Mini/Micro LED chips and completing the production of display screens through steps such as cutting, splitting and mixing. It combines the flexibility of SMD with the stability of COB to achieve a double improvement in brightness and contrast.
② Features and advantages: MIP technology has multiple advantages such as high-definition picture quality, high stability, high protection performance and flexibility. Its picture quality is particularly outstanding, and it can present a more delicate and realistic image effect. At the same time, the protection performance of MIP display screens is also strong, and it can adapt to a variety of harsh environments. In addition, MIP technology also has good flexibility and scalability, which can meet the needs of different customers.
③Application limitations: At present, MIP technology is not fully mature, and the cost is relatively high. Therefore, its market promotion is subject to certain restrictions. At the same time, due to the particularity of MIP technology, its maintenance and replacement costs are relatively high.
④Market positioning: MIP technology is regarded as a potential stock of future LED display technology with its unique advantages and potential. In diversified scenarios such as commercial display, virtual shooting, and consumer fields, MIP display screens have great application prospects and market potential.
2, Market trends and thinking
With the continuous development of the LED display industry, the market has higher and higher requirements for picture quality, stability, cost, etc. From the current market trend, COB and MIP technology schools have great development potential.
COB technology has occupied an important position in the high-end market and professional display field with its excellent performance and high-end market positioning. With the continuous advancement of technology and the continuous expansion of the market, COB technology is expected to achieve larger-scale market applications in the future. MIP technology, with its unique advantages and potential, is regarded as a potential stock of future LED display technology. Although MIP technology is not yet fully mature and has a high cost, it is expected to gradually reduce costs and expand market share in the future with the continuous advancement of technology and the promotion of the market. Especially in diversified scenarios such as commercial display and virtual shooting, MIP technology is expected to play a greater role.
However, we cannot ignore the existence of SMD and GOB technology schools. SMD technology still has broad application prospects in the mid-to-low-end market and general commercial display projects with its cost-effective advantages. GOB technology continues to play an important role in the outdoor display market with its unique protection performance and stability.
