Safety Analysis of COB LED Display
1. Electrical safety:
-protection against electric shock and short circuit
The design of COB LED display screens takes electrical safety into full consideration. Its packaging technology allows the LED chip to directly contact the substrate, reducing the possibility of exposed wires, thereby reducing the risk of electric shock.
Modern COB LED displays are also equipped with overcurrent protection, short circuit protection and overload protection circuits to ensure that the power supply can be automatically cut off in the case of unstable power load to prevent equipment damage or fire.
2. Heat dissipation and temperature control
COB LED display screens have excellent heat dissipation performance, and its heat dissipation design effectively reduces heat accumulation by optimizing the heat conduction path.
Since COB technology integrates multiple LED chips on a substrate, the heat dissipation efficiency is high and the temperature rise is low, reducing the safety hazards caused by overheating.
Efficient heat dissipation design not only improves the performance of the display screen, but also reduces the risk of fire caused by overheating.
Heat dissipation is one of the main safety hazards faced by LED display screens in long-term operation, especially in high brightness mode. COB LED effectively reduces heat accumulation through integrated design to ensure its safe operation.
3. Fire safety
COB LED display screens use flame-retardant materials in the material selection and manufacturing process, which can effectively resist sudden situations such as high temperature and fire.
In addition, due to the superiority of its heat dissipation design, it can maintain a lower temperature when working under high load, reducing the fire hazard caused by excessive temperature.
Flame retardancy and efficient heat dissipation design make COB LED display screens safer when facing sudden fire or high temperature environment, ensuring long-term stable operation of the equipment.
4. Waterproof, dustproof and environmental adaptability
COB LED displays usually have strong protection capabilities, especially the IP protection level for outdoor or complex environments.
For outdoor applications, COB LED screens can effectively prevent water and dust, avoiding equipment damage caused by bad weather (such as heavy rain, dust accumulation, etc.). This makes it safer in high humidity, high temperature or dusty environments.
Waterproof and dustproof design can effectively protect the internal circuit of the display, prevent circuit board corrosion, short circuit and other safety issues, and ensure stable operation of the equipment.
5. Human health and safety: low radiation design
The design of COB LED display uses low radiation technology. Compared with traditional display technology, COB LED screens can significantly reduce blue light radiation and reduce potential impact on human health.
This is especially important in environments where you need to stare at the display for a long time, such as conference rooms, command centers, etc.
Low blue light design reduces visual fatigue and potential eye health problems, making COB LED display a healthy and safe choice for long-term use.
Customization of COB LED display
1. Size and shape customization
The modular design of COB LED display allows the size and shape of the screen to be flexibly customized to adapt to different installation environments and space layouts.
Whether it is a standard rectangular screen or a creative curved, circular, or special-shaped display, it can be tailored according to customer needs to ensure the best display effect.
2. Resolution and pixel pitch customization
The pixel pitch of COB LED display can be customized according to viewing distance and application requirements.
Small pixel pitch (such as P1.25, P1.56) is suitable for close viewing, while larger pixel pitch (such as P2.5, P3) is suitable for long-distance applications, ensuring that each scene can present the best display effect.
3. Function and technology integration
COB LED display can not only provide basic display functions, but also integrate video processing systems, content management systems, and interactive functions.
According to specific needs, customers can choose customized functions, such as touch screen interaction, real-time data display, etc., to enhance the interactivity and intelligence of the screen.
4. Appearance and brand customization
The appearance design can be customized according to the customer’s brand image, including cabinet color, shape design, and LOGO customization to enhance the visual impact of the brand.
Through personalized appearance design, COB LED display can help enterprises highlight their brand image in commercial places and enhance market awareness.
Adaptability analysis of COB LED display screens in different regions
Climate adaptability
High temperature environment: COB LED display screens have good heat dissipation design and are suitable for high temperature areas, but additional heat dissipation measures are still required under extremely high temperatures.
Wet environment: Waterproof and moisture-proof design (IP65) makes it adaptable to humid areas and resists moisture and corrosion.
Cold environment: Low energy consumption characteristics make it work normally in cold areas, but the shell design or heating system needs to be strengthened to cope with severe cold.
