COB LED Display Brightness Matter
As the technology behind Chip-on-Board (COB) LED screens evolves, challenges like calibration and surface treatment have been known to affect brightness levels, often resulting in sacrifices of 30-50% compared to traditional LED displays. In typical scenarios, most COB LED displays offer brightness ranging from 400 to 800 nits. However, advancements in COB LED technology have led to breakthroughs that surpass these norms, with some COB LED displays achieving brightness levels of up to 2000 nits. This represents a significant leap forward in indoor display solutions, ensuring that even in environments with high ambient light or direct sunlight exposure, COB LED screens can deliver vibrant, clear imagery without compromise.
High Brightness COB LED Display Applications
High brightness is typically required for indoor LED screens in environments with high ambient light levels or direct sunlight exposure. This includes settings such as:
- Retail Stores: Indoor LED displays in retail environments often need high brightness to compete with ambient lighting and draw attention to products and promotions.
- Shopping Malls: LED screens in shopping malls may be exposed to bright overhead lighting and large windows, requiring high brightness to maintain visibility.
- Airports and Transportation Hubs: In transportation terminals where natural light is abundant, high brightness ensures that information and advertising on LED displays remain visible to travelers.
- Sports Arenas and Auditoriums Indoor venues with large windows or bright lighting fixtures may require high brightness LED displays to maintain visibility during events.
Patented COB Technology
The patented COB three-layer surface treatment technology consists of three key layers:
1. Black Bottom Adhesive Layer: This layer avoids covering the light-emitting chip, ensuring that the brightness of the LED is not affected and enhancing the contrast ratio of the COB module.
2. Buffer Layer: This layer improves resistance to impacts and enhances durability in low temperatures.
3. Highly Transparent Top Layer: This layer provides superior surface protection, ensuring the display remains clear and well-protected.
Together, these layers enhance the performance and durability of the COB module.
