CRT Full Form: History, and Advantages
CRT in TV – Wikipedia


In this article, we will discuss CRT Full Form, what is meaning, history, and advantages of CRT screen technology. CRT stands for “Cathode Ray Tube“. This technology was once the prima donna in the world of visual displays before flat screens such as LEDs and LCDs existed. Even though it has been replaced by more sophisticated technology, knowledge of CRT is still important for understanding the history and development of display technology.

What are CRTs?

A cathode ray tube (CRT) is device used to display images of old televisions, computer monitors, and radar. CRT works on the principle of electron movement in a tube which produces light which is then displayed as an image on the screen. The CRT screen consists of a vacuum tube coated with phosphor, an electron cathode, and other components.

The History of the Development of CRT Screens

2.1 The Beginning of the Discovery of CRT

The technology of CRT was first developed by Ferdinand Braun (German scientist) in the late 19th century. In 1897, Braun managed to invent a vacuum tube that allows electrons to move and produce light. This discovery became the basis for the development of CRT technology in the future.

2.2 Emergence of CRT Television

After the initial invention by Ferdinand Braun, CRT technology began to be developed further and in the 1920’s, the first CRT television was introduced. CRT televisions use CRT tubes as the main part to display images and sound. At that time, CRT televisions used monochromatic systems with low resolution, but this was an early milestone in the development of visual display technology.

2.3 Development of CRT Computer Monitors

In addition to television, CRT technology is also used in computer monitors. At first, CRT monitors were large and heavy and had low resolutions. However, as the new technology of display, CRT monitors have become more compact, have higher resolutions, and are able to display colors better. CRT monitors were one of the top choices for computer users until the advent of flat screens.

Advantages of CRT Screens

Why Was This Technology Ever Popular? there are reasons:

3.1 Accurate Color Response

One of main advantages of a CRT screen is its ability to display colors with an accurate response. This has made CRT screens widely used in the graphic design, photography and printing industries in the past.

3.2 High Contrast

CRT screens also have high levels of contrast, which means the difference black and white can be shown clearly. These advantages make CRT screens suitable for displaying images with fine detail, especially in applications requiring high contrast such as video editing and graphics processing.

3.3 Wide Viewing Angle

CRTs also have a wider viewing angle compared to some flat screen technologies. That is, the image displayed on the CRT screen remains clear and does not experience distortion when viewed from various angles. This advantage is especially important in applications such as the use of large indoor monitors or in presentations that involve an audience from different directions.

3.4 Flexible Aspect Ratio

CRT screens also have an advantage in terms of flexible aspect ratios. Aspect ratio is the ratio between width and height of the image. In CRT screens, users can easily adjust the aspect ratio as needed, thus enabling display of images to suit individual preferences and needs.


CRT Full Form – Although CRT screens have been replaced by more sophisticated flat screen technologies such as LEDs and LCDs, knowledge of CRTs remains important in understanding the history and development of visual display technology. CRT was once the leading technology in the world of visual displays with the advantages of accurate color response, high contrast levels, wide viewing angles, and flexible aspect ratios. Although no longer dominant, CRTs remain an important part of the history of display technology development and make major contributions to the electronics industry.
