CRTGeräten
CRTGeräten is a German term that translates to "CRT devices" or "CRT equipment." CRT stands for Cathode Ray Tube, a vacuum tube technology that was historically used in televisions and computer monitors. These devices produce an image by firing a beam of electrons onto a fluorescent screen. The electron beam is deflected by magnetic fields, allowing it to scan across the screen and illuminate pixels of varying brightness and color.
CRT technology dominated the display market for decades, offering good image quality and relatively low cost.
In recent years, CRTGeräten have largely been replaced by newer technologies such as LCD (Liquid Crystal Display)
