Cathode-Ray Tube Day is a yearly event celebrated on December 20th in the US, dedicated to acknowledging the contributions of technology in our lives. A cathode-ray tube (C.R.T.) is a vacuum tube containing electron guns that emit electron beams, which are converted into images on a glowing screen. These images can range from television or computer monitor displays to electrical waveforms for devices like oscilloscopes or radar targets. This holiday highlights the significance of this technology and its various applications.

📜 Cathode-Ray Tube Day History

The C.R.T., according to legend, is a type of vacuum tube enclosed in a large glass envelope. It typically contains one or more electron cannons and has a phosphorescent screen built into it. By modulating, accelerating, and deflecting electron beams onto the screen, various images can be displayed, such as those seen on TVs, computer screens, radar targets, and oscilloscopes. Cathodes, which are negatively charged electrodes, play a crucial role in C.R.T. displays. In C.R.T. televisions and computer displays, the entire front area of the tube is scanned in a specific pattern known as a raster.

The discovery of cathode rays in early Crookes tubes dates back to 1869. In 1897, Ferdinand Braun, a German physicist, invented the initial version of the C.R.T., known as the Braun Tube. Germany manufactured the first commercially available C.R.T. television sets in 1934. The term “cathode-ray tube” was trademarked by R.C.A. in 1932 but became available to the public domain in 1950. In the late 2000s, cathode ray tubes started being replaced by flat panel display technologies such as L.C.D., O.L.E.D., and plasma configurations.
