CRT - Cathode Ray Tubes

Cathode ray tubes (CRTs) revolutionized early display technology, serving as the backbone for televisions and computer monitors for decades. Employing vacuum tubes, CRTs project images by firing electron beams onto a phosphorescent screen. Their importance lies in their versatility and reliability. CRTs offered vibrant color reproduction and sharp resolution, making them the standard for visual display before the rise of LCDs and LEDs. Beyond entertainment, they found utility in scientific instrumentation and radar systems. CRTs represent a milestone in the development of electronic displays, laying the groundwork for modern screens while embodying an era of innovation and technological progress.

Ferdinand Braun (1850–1918) was a German physicist who made significant contributions to the development of wireless telegraphy. He invented the Braun tube, a precursor to the cathode ray tube, vital for early television technology. Braun's work on radio transmission and reception led to the co-invention of the first practical wireless telegraphy system with Guglielmo Marconi. His research on crystal diodes laid the groundwork for semiconductor electronics. In 1909, he was awarded the Nobel Prize in Physics for his contributions to wireless telegraphy. Braun's innovations profoundly influenced telecommunications and laid the foundation for modern electronics. Learn More:
