We had a major electrical storm and our house was zapped, and with it went the tube in my trusty cathode ray television that I’d held onto for more than ten years.

Scottish inventor John Logie Baird is credited with the first demonstration of this TV technology in 1925. I just thought that I would stay with my trusty cathode ray tube television for as long as I could hold out before I had to switch to flat panel televisions. The invention of the cathode ray tube in 1897 is what originally made television possible. I had a cathode ray tube TV for the longest time, even as the rest of the world was moving into flat panels. A glass cathode-ray tube which contains a vacuum has three electron guns at its narrow end, each containing an anode and cathode assembly.
At all other times I use my newer computer with the flat panel. I use it from time to time when I don’t need to do any heavy duty stuff. I was told that the lifespan on these things was supposed to be 8 years but I’ve had it for 12 years and it’s still going strong. May 30, - I still have a Pentium II collecting dust in my basement and it’s got a cathode ray tube monitor that still works. It is typically divided into four sections which are display, vertical controllers, horizontal controllers, and Triggers. One tube goes out and you have to track it down and replace it, otherwise everything won’t work right. The CRO stands for a cathode ray oscilloscope.
It’s like wiring your house for Christmas. Imagine a computer made up of thousands of tubes. This was before the transistor came on the scene. It was the ENIAC computer, built around the late 1940s I believe, and had stacks and stacks of cathode ray tubes to do its processing. The first computer ever invented was made entirely of cathode ray tubes. June 2, - Here’s an interesting bit of trivia. Still, the CRT maintains its popularity in television systems, as evidenced by the fact that the television is frequently referred to as “the tube.”Ĭathode ray tubes play an important role in oscilloscopes. Organic light-emitting diode (OLED) displays are also used to produce images. However, there have been many new developments in display technology, such as plasma screens, liquid crystal display televisions (LCD TVs), and digital light processing (DLP) devices. The cathode ray tube still plays a major part in television sets and many other electronic devices. It was also more durable than some of the previously introduced CRTs. Du Mont introduced the first tube that was considered practical for use in a television set. An oscilloscope CRT is much smaller than a TV CRT because the screen is smaller and the electron beam does not travel as far. As its intensity varies, the beam creates the moving images that viewers see. Called the kinescope, it was designed for used with some of the earliest televisions. In a TV CRT, horizontal and vertical toroidal deflection coils on the outside of the neck cause the beam to scan the screen. It is mainly used for entertainment, information and education.
In 1929, Vladimir Kosma Zworykin created another type of CRT. The moving images that it receives from a nearby broadcasting station is projected in three dimensions by the cathode ray tube or CRT and it also has an audio decoder to reproduce the sounds from the transmitted radio signals through the audio speakers. Braun’s cathode ray oscilloscope is considered the predecessor of modern tubes used in television sets. The screen of this tube would display a light when a beam of electrons touched it. This new technology was called a cathode ray oscilloscope. His invention consisted of a tube with a fluorescent screen.
