I’m finding myself thinking more esoterically about colors and perception lately. We all know color matters in displays, it’s one of the defining features of QLED technology. You might have seen my last article that mentioned QLEDs for auto tail lights as a possible replacement for OLED taillights. Let me take you for a walk down the meandering path my mind can take that I think might have some value to those of you who think about color (almost) as much as I do.
Why are cars using OLED tail lights?
The main reason manufacturers are looking to OLED is for flexibility in design which leads to a more marketable vehicle. I doubt there is an efficient reason to put OLEDs instead of red LEDs on a vehicle, but with OLEDs, you get a distinctly different look. Smooth, large area sections that can be freely split up into multiple lights so that unique patterns can be displayed. Perhaps just a novelty, but just like displays, car manufactures are looking for every edge they can get in a competitive market. In the end, they just look cool. This got me thinking about other benefits of new light sources in vehicles. Are they brighter? Can following cars see the OLED brake lights better? Is the color unique? Does color impact how the taillights are perceived? Color… ahh yes, color!
