[Safety & Beyond] Ultimate Precision Lighting Using Samsung’s Semiconductor Engineering
Precautionary safety is becoming a central focus for the automotive industry as new and revolutionary technologies are changing the way we drive. Within this global movement, interest in “active safety”―functions that detect risk factors and prevent potential accidents―is on the rise.
The automotive lighting sector has been contributing to this trend by introducing a variety of innovations, the most prominent of which is Adaptive Driving Beams (ADBs). ADB headlights are able to automatically adjust headlamp lighting based on the traffic environment to improve the visibility of drivers. And, Samsung’s PixCell LED technology is playing a vital role in creating the most advanced form of ADB.
The name “PixCell” was conceived from the fact that each segment in a PixCell LED is able to operate as its own individual cell. Applying Samsung’s monolithically integrated LED technology with the PixCell LED embraced more than 100 segments into a single LED chip, with a wall structure between segments to isolate each segment. Subsequently, it makes the LED alignment far more precise than that of peer products, which have separate LED packages mounted on a circuit board one by one. This unique technology gives Samsung’s PixCell LED its unrivalled 300:1 contrast-- a ratio that is nearly three times higher than conventional competing products relying on legacy technologies.
Samsung’s PixCell LED is an LED light source with industry-leading precision that dramatically enhances light accuracy, best optimized for intelligent headlights. It enables an ultra-fine, automated lamp control to create better contrast, which is a key element of intelligent headlamps. Lamps with a higher contrast ratio can more accurately distinguish which areas of the road need to be lit or dimmed at any given moment. In doing so, the headlamp adapting the PixCell LED not only improves visibility, but also prevents glare from oncoming cars and the traffic preceding it. This provides a significantly safer environment for all drivers on the road at night, and in inclement weather such as fog and heavy rain.
With the goal of achieving safer driving at night and under tough conditions, Samsung’s PixCell LED technology generates what can easily be considered the premium contrast for high-convenience, pinpoint-controlled automotive lamps. It promises unmatched lamp precision for the industry’s most trustworthy ADBs.
