LEDs Instead of Display

Do we want to listen to music or watch TV? Large, beautiful displays may please the eye of the beholder, but the larger and more colourful the pretty displays become, the more high-frequency interference they produce. After all, the many pixels want to be driven constantly at high frequency. And this, in turn, is highly problematic in terms of the core task of our devices, music transmission.
In contrast, the less glamorous looking classic LEDs are controlled by a DC voltage that is not critical in terms of sound. It is stably applied as long as the LED is lit and is off when the LED remains dark. These LEDs still give the viewer exactly the information needed, but without any negative influence on the core task of the device. That’s why all our devices work with a few displays and these all are by normal LEDs.
