CRT Full Form
A cathode ray tube (CRT) is a vacuum tube containing one or more electron guns and a phosphorescent screen used to display images. The image may be a direct view of the object or a projected image.
Working on Cathode Ray Tube
When a voltage is applied to the cathode of a CRT, a current flows, and this current is drawn to the cathode by the negatively charged electron gun. The electrons are then accelerated and fired at the phosphor coating inside the CRT.
When the electron collides with the phosphor, it causes the phosphor to release energy in the form of light. This light is then focused and projected onto the screen of the CRT.
Basic Parts of Cathode Ray Tube
The Cathode Ray Tube (CRT) is a vacuum tube used to display images. It is made up of three key parts: the cathode, the anode, and the screen.
The cathode is a heated filament that emits electrons. The anode is a metal plate that attracts the electrons and accelerates them towards the screen. The screen is a phosphor-coated glass surface that emits light when struck by the electrons.
Applications of CRT
Applications of CRT include the following:
- Television
- Monitors
- Laptops
- Desktop computers
- Printers
- Scanner
- Copiers
Limitations of CRT
There are a few limitations of CRT. First, the image on a CRT is not as clear as on newer display technology, such as an LCD. Second, CRTs can be bulky and heavy. Finally, they use more power than newer display technologies.
