Mask on Board (MOB) technology in the context of direct view LED screens refers to a technique where a protective mask is applied to certain areas of the LED module while leaving the SMD (Surface-Mount Device) LEDs exposed. The mask is typically designed to shield the areas surrounding the LEDs, offering protection against external elements like dust, moisture, and minor physical impacts, but it does not encapsulate the entire surface of the module as seen in GOB (Glue on Board) technology.
Benefits of Mask on Board (MOB) Technology:
- Targeted Protection: MOB technology focuses on protecting the circuit board and the sensitive areas around the LEDs without fully covering the LEDs themselves. This selective masking provides protection from dust, moisture, and debris, particularly in harsh environments.
- Preserved Brightness and Clarity: By leaving the SMD LEDs exposed, MOB allows for maximum light transmission and brightness, ensuring the display maintains its optimal visual performance. There is no loss in light output or image clarity since the LEDs are not covered by any material.
- Reduced Risk of LED Damage: Although the LEDs are exposed, the mask helps to protect the LED chips from potential damage caused by external forces that could otherwise impact the surrounding areas of the module.
- Better Heat Dissipation: With the LEDs not encapsulated, heat can escape more efficiently, reducing the risk of overheating and extending the lifespan of the LED components.
- Improved Contrast and Viewing Experience: Since the mask does not cover the LEDs themselves, there is no additional material that could cause glare or reflection. This leads to better contrast and overall image quality, particularly in environments with varying lighting conditions.
- Cost-Effective Protection: MOB technology provides a cost-effective middle ground between fully covering the module (as in GOB) and leaving the module entirely unprotected. It offers sufficient protection without the added expense or complexity of fully encapsulating the LEDs.
Applications of MOB:
- Indoor and Semi-Outdoor Displays: Where the environment isn't as extreme as outdoors, but there is still a need for some level of protection.
- Interactive Displays: In situations where physical interaction might occur, such as touch displays or installations in high-traffic areas, MOB can help prevent accidental damage to the circuitry while maintaining display quality.
In summary, Mask on Board (MOB) technology is a solution that combines partial protection with maximum LED performance, providing a balance between durability and visual quality. Ad Art provides Mask on Board as an option by request on select indoor LED products.
