COB (Chip on Board) display is an advanced LED display technology that surpasses traditional SMD (Surface Mounted Devices) displays in many aspects. The significant advantages of this technology include:
1. Ultra-fine pitch and high definition:
COB display can easily achieve a dot pitch below 1.0mm, or even an ultra-fine pitch of 0.1mm, which makes the display more delicate and the resolution greatly improved. Smaller dot pitch means more pixels per unit area, resulting in fuller and clearer visual effects. The application of this technology gives COB display an unparalleled advantage in displaying details, especially when displaying high-definition videos and images, it can provide a richer and more delicate visual experience.
2. Surface light source emits light, and the viewing experience is better:
Unlike traditional point light sources, COB display realizes "surface light source" emission, and the light is more uniform and soft, and it will not feel dazzling even when viewed at close range, which is suitable for occasions that require long-term staring or close viewing. This uniform luminous characteristic is also very friendly to photography and videography, and can reduce the effects of moiré and other effects, thereby providing more stable and high-quality image output.
3. Excellent protection performance:
Because COB technology directly encapsulates the light-emitting chip on the PCB board and uses epoxy resin glue to cure, the device is completely sealed and not exposed, so it has a very high protection level (such as IP66), which can effectively resist damage from natural and human factors such as external impact, vibration, water vapor, oxidation corrosion and static electricity. This design makes the COB display screen less susceptible to damage during transportation, installation and maintenance, significantly improves durability, and has a much higher load-bearing capacity than SMD displays. This high protection level makes COB displays particularly suitable for use in harsh environments, such as outdoor advertising, industrial monitoring and other scenes.
4. Color performance and image quality optimization:
COB technology improves color uniformity and consistency by reducing the dot pitch, making the display color softer and more delicate, and enhancing color saturation and contrast, thereby providing a better visual experience. The color expression of this technology enables COB displays to meet the needs of professional fields in terms of color reproduction and visual effects, such as film and television post-production, high-end advertising display, etc.
5. Easy maintenance and long service life: The improvement of packaging method reduces exposed parts, reduces the failure rate caused by dust, moisture, mechanical shock and other factors, and extends the overall service life of the display. At the same time, the maintenance cost is also reduced accordingly, because it is not easy to drop or break the lamp, which reduces the frequency of maintenance. This low-maintenance design concept makes COB display screen have obvious advantages in long-term operating costs, especially suitable for application scenarios that require long-term stable operation, such as airports, stations, shopping malls and other public places.
6. Technological innovation and intellectual property rights:
Although there are relatively few manufacturers who currently master COB display technology, the pioneers in this field have established competitive advantages through continuous technological innovation and patent layout, such as Leman and other companies. Their COB small-pitch LED display technology not only improves industry standards, but also provides users with more possibilities. The technological innovation of these companies has not only promoted the development of display technology, but also brought more innovative application scenarios and solutions to users.
In summary, COB display screens have become an important choice in the high-end display market with their ultra-fine pitch, excellent protection capabilities, excellent display effects, low maintenance costs and technological leadership, especially in application scenarios that require high definition, high reliability and long-term stable operation.
