Compared with traditional LED screens, COB LED screens have the following obvious advantages:
1. Higher stability and reliability:
COB packaging technology directly packages the LED chip on the PCB board, reducing the welding points between the lamp beads and the PCB board in traditional LED screens, thereby reducing the failure rate caused by poor welding.
Since the LED chip is completely encapsulated inside the PCB board, it effectively prevents moisture, dust and other impurities in the external environment from corroding the LED chip, improving the stability and reliability of the product.
2. Smaller dot spacing and higher definition:
COB packaging technology makes the spacing between LED chips smaller, which can achieve smaller dot spacing and improve the resolution and clarity of the screen.
Smaller dot pitch also means higher pixel density, making the display more delicate and realistic.
3. Better heat dissipation performance:
COB packaging technology uses an overall packaging structure to directly dissipate the heat generated by the LED chip through the PCB board, improving heat dissipation efficiency.
Good heat dissipation performance helps reduce the operating temperature of the LED chip, extend its service life, and improve the reliability and stability of the entire screen.
4. Lower maintenance costs:
Because the COB LED screen has better packaging protection and stronger anti-collision ability, it is not easy to cause the lamp beads to fall or be damaged during installation and use.
This means that the maintenance cost of COB LED screens is lower, reducing users’ worries.
5. Better visual effects:
The COB LED screen uses a "surface" light source to emit light, which effectively suppresses the occurrence of moiré patterns and reduces light refraction, making the colors of the display more realistic and soft.
At the same time, due to the reduction of point spacing and the increase of pixel density, COB LED screens have better expressiveness and visual impact when displaying highly dynamic images.
6. Higher integration and flexibility:
COB packaging technology integrates multiple LED chips into one package, improving the integration of the entire screen.
This high level of integration makes COB LED screens more flexible in design and manufacturing, and can be customized and optimized according to different application scenarios and needs.
To sum up, compared with traditional LED screens, COB LED screens have higher stability and reliability, smaller pixel pitch and higher definition, better heat dissipation performance, lower maintenance costs and more Good visual effects and flexibility. These advantages make COB LED screens widely used in advertising media, sports venues, convention and exhibition centers and other fields.
