Many indoor banner advertisements are created using LED banner displays. They attract pedestrians’ attention with their high-brightness effects, thereby increasing store sales.
Advantages of COB LED Display Screens
A black film layer is applied to the surface of the COB LED display to enhance its protective performance. Even if water accidentally splashes onto the screen, there is no need to worry about any issues arising.
Conventional LED modules require connection via data cables and power cables. However, our COB LED display has been improved to eliminate the need for any cables. Simply align the interface and insert the LED module.
The COB LED display screen has been meticulously polished, making both the front and back surfaces extremely smooth. This smooth surface makes daily cleaning of the screen extremely simple.
Our COB LED display screen is significantly lighter and thinner than traditional small-pitch LED cabinets, with a thickness of just 28 millimeters and a weight of only 5 kilograms. The ultra-light and ultra-thin design makes screen installation much easier.
Through its unique internal design, the JYLED COB LED display offers a viewing angle of up to 175°. No matter where you stand, you will see consistent display quality.
The JYLED COB LED display incorporates a high-performance IC. This IC comprehensively controls all information across the entire screen, including data processing, format decoding, and contrast display.
Fanless design
Thanks to its excellent circuit layout, the COB LED display does not require additional fans for heat dissipation. Through a unique circuit design, the temperature of the COB LED display remains around 45°, at which temperature the internal components can perform at their best.
Ultra-fine Pixel Pitch
Conventional LED displays typically have a pixel pitch of over 1 millimeter. Achieving a pixel pitch below 1 millimeter would result in significantly higher costs. Therefore, in manufacturing this COB LED display, we abandoned the traditional SMD packaging method and adopted the flip-chip COB packaging approach. This method eliminates the need for metal brackets, enabling the achievement of an ultra-fine pixel pitch below 1 millimeter.
High Energy Efficiency
The LED chips in JYLED’s COB LED display use gallium nitride as the raw material for the chips, which is more energy-efficient than gallium arsenide or gallium phosphide. Based on our actual data measurements, under the same brightness conditions, the energy efficiency of JYLED’s COB LED display is 40% higher.
Precision-coated black film for a smoother screen
Unlike the conventional waterproof resin coating method, the surface of the COB LED display is coated with a black film. This black film can be distinctly felt when touched by hand. With conventional coating methods, touching the screen reveals a noticeable granular texture (caused by the LED chips on the screen). However, the COB LED display screen with a black film coating feels completely smooth to the touch, with no granular texture at all.
COB LED Display vs. Quantum Dot LED Display
COB LED displays and quantum dot LED displays are two ultra-fine pitch LED displays recently developed by JYLED. What are the differences between these two displays? Let’s take a closer look.
Direction-Free Seamless Integration
When using COB LED modules for seamless integration, it is important to note the arrow directions on the circuit board, and the modules should be integrated according to these arrow directions. However, quantum dot LED displays do not distinguish between directions, so this consideration is unnecessary during integration.
Nearly Perfect Pure Color Effect
After multiple improvements to the COB LED display, this model now achieves 95% pure color effect. Quantum dot displays, however, achieve nearly perfect pure color effect (99% pure color).
Lower heat generation
Quantum dot LED displays have upgraded power consumption control modules that automatically adjust power consumption based on brightness and performance, resulting in temperatures approximately 1-5 degrees lower than COB LED displays.
Price
Quantum dot LED displays are an upgraded version of COB LED displays, so they are slightly more expensive than COB LED displays. If you prioritize cost-effectiveness, COB LED displays are a better choice. If you prioritize image quality and are not overly concerned about price, quantum dot LED displays are recommended.

Application scenarios for quantum dot LED displays
Traditional display devices have low brightness and poor image quality, especially when there are many people in the conference room. Employees sitting at the edges of the room can barely see the content on the screen.
The introduction of COB LED displays has perfectly addressed these shortcomings of traditional displays. With their high-definition, high-brightness, and multi-angle viewing features, the screen content can be clearly seen from any location.
Monitoring rooms require high-definition cameras and display devices to ensure criminals cannot escape detection. When used in conjunction with CCTV, COB LED displays allow every movement to be clearly observed, effectively deterring criminal activities.
Our COB LED display screen can simulate the display effects of a cinema, creating an excellent viewing atmosphere. You no longer need to spend time going to the cinema; you can enjoy cinema-level quality right at home.
Through the ultra-high resolution of COB LED screens, customers are immediately drawn to the content displayed on the screen the moment they enter the store. When customers notice the screen content, it often significantly improves the conversion rate.
