CRT full form is Cathode Ray Tube. In a cathode-ray tube (CRT), a specialized vacuum tube, pictures are produced by an electron beam impacting a phosphorescent surface. The vacuum tube used in classic computer displays and televisions has one or more electron guns and a phosphorescent screen. CRTs are typically used for desktop computer displays. The “picture tube” in the receiver of a television is comparable to the CRT in the computer’s display.
Features of CRT:
- Physical characteristics: CRT is heavier and larger in stature.
- Contrast: They have a significantly higher contrast ratio and make more details in dark photographs apparent. While they don’t offer LCD displays with brighter white levels.
- Cost: CRT is vanishing from the market. The majority of manufacturers have ceased CRT production. It is relatively affordable and extremely elusive on the market.
- User-Friendliness: CRT displays have a 4:3 aspect ratio. You have probably seen a black bar at the top & bottom of standard televisions. It signifies that it is unable to utilize the entire screen. LCD panels, on the other hand, have significantly wider screens, therefore they either have very few bars or none at all.
History of CRT
- Julius Plücker and Johann Wilhelm Hittorf are the founders of cathode rays whereas Ferdinand Braun developed the very first CRT.
- The First Cathode Ray Tube televisions available commercially in Germany were made by Telefunken.
Applications of CRT
- CRT is used as one of the most common displays on television.
- As the fast-moving cathode rays stop X-rays are generated
- CRT is also used in cathode-ray oscilloscopes.
- CRTs are quite low in price.
- CRTs have no movable artifacts and a very quick reaction time.
Drawbacks of CRT
- The display tech of CRT depends on the size.
- CRT displays images with lower pixel density.
- They use a great deal more power than normal.
- They are large, powerful, and bulky.
- Comparatively bright but not as bright as LCD.
