- Mini-LED: A newer innovation, mini-LEDs are smaller than traditional LEDs and can be used in larger arrays to enhance brightness and contrast, especially in HDR (High Dynamic Range) content. This advancement allows for more precise local dimming, improving the overall picture quality in scenes with varying brightness levels.
Another emerging type is MicroLED, which consists of microscopic LEDs that can be individually controlled. This technology promises to deliver even greater color accuracy and energy efficiency, as well as the potential for seamless, large-scale displays without the bezels that typically separate panels. As the technology continues to evolve, we can expect to see even more innovative applications of LED technology across various industries, from advertising to automotive displays.
