Samsung has just detailed what will be its next-generation LED module for smart headlights, better known as PixCell LED. According to the company, this solution is perfect for creating energy-efficient lamps for the modern design cars of the future.
Specifically, it is an Adaptive Driving Beam (ADB) solution. Samsung used its semiconductor technology to improve the ADB concept in several areas. Apparently, the company wants to get ahead with these technologies to dominate the car market.
Based on the ISOCELL
It seems that the PixCell LEDs use technology very similar to that of the ISOCELL, so we could say that they are based on it. They will make use of what Samsung called the Silicon Wall, that is, a solid wall between the pixels. In this way, each of them is isolated for better control of the lights, which is precisely what ADB technology tries to achieve.
The design of the ADB systems aims to minimize the light that dazzles when there are any vehicles approaching from the opposite direction, in addition to providing an intense luminosity for the driver. In addition, it reduces the intensity of our headlights in certain areas so as not to dazzle other vehicles. Since pixel isolation is very important for light control, we understand its great importance for these LED headlights.
Silicon Wall technology is allowing Samsung the space between pixels to be only 25 micrometers, that is, one-sixteenth the current size of LEDs. Therefore, it is more and more possible to reduce the size of car headlights and optimize their system.
Additionally, PixCell LEDs use a Monolithic Integrated Architecture, which incorporates 100 ultra-small LED segments on a single chip. Each of the LEDs can be manipulated individually. With this, plus a module that occupies a small space of use, PixCell LED adjusts to different international needs and can be adapted with minimal adjustments in your software.
Thanks to the above, car manufacturers would have a great advantage when using Samsung technology in their international vehicles, since they would only need a few small adjustments via software, such as to switch to when driving on the right or left.
At the moment, this technology is the only representative until the first PixCell LED vehicle hits the streets. Still, Samsung has already shipped more than 300,000 modules for electric vehicles.
