Curious About COB Displays? Here’s What You Need to Know!
LEDA DISPLAY at INTER BEE 2019: Showcasing perfect LED display solutions
Welcome to visit our booth from Nov. 13th to 15th
Booth: Hall 6, 6208
1. What is a COB LED Display?
COB (Chip on Board) technology is a unique LED display packaging method that sets itself apart from traditional LED technology. This innovative approach involves mounting multiple LED chips directly onto a single circuit board, omitting the need for individual packaging around each chip. The result is higher brightness, better heat dissipation, and an exceptionally seamless display surface.
2. Unique Benefits of COB LED Displays
2.1 Advantages Over Traditional LED Screens
COB LED displays offer substantial benefits over standard LED technology. With no visible gaps between LED chips, COB screens provide uniform lighting and effectively eliminate the “screen door effect” seen in traditional displays. COB also produces more accurate colors and offers significantly improved contrast levels, enhancing the viewer’s experience.
COB technology’s smaller LED chip size allows for a higher chip density on the board, making the display more compact. In comparison to Surface-Mounted Device (SMD) technology, COB offers uniform display quality, even at close viewing distances, along with excellent heat management, which enhances both stability and reliability. COB’s packaging increases resistance to dust, moisture, static, and physical damage, with its IP65-rated surface making it suitable for demanding environments.
Unlike SMD technology, which requires a reflow soldering process, COB does not need reflow, which can degrade adhesive at high temperatures. This makes COB technology inherently more stable.
2.2 Precision in Pixel Pitch
COB LED technology allows for smaller pixel pitches, which translates into higher pixel density and improved image resolution. Even at close range, viewers can enjoy sharp, clear images.
2.3 Efficient Heat Dissipation and Lighting Performance
With COB, the LED chip is directly bonded to the PCB, providing a larger heat dissipation surface and reducing light degradation compared to SMD technology, which primarily relies on bottom anchoring for heat release.
2.4 Wider Viewing Angles
Thanks to its small-pitch technology, COB delivers a broader viewing angle and enhanced brightness, making it ideal for both indoor and outdoor settings.
2.5 Durability and Resistance
COB’s impact-resistant design withstands exposure to moisture, dust, oil, and oxidation, ensuring long-lasting resilience.
2.6 High Contrast Levels
Contrast is a vital aspect of LED displays. COB technology achieves remarkably high contrast, with static ratios between 15,000 and 20,000 and dynamic contrast ratios up to 100,000.
2.7 Eco-Friendly and Energy-Efficient
COB technology also leads the way in energy efficiency compared to SMD, helping lower operational costs for large-screen applications used over extended periods.
