A technician carefully replaces the CRT in an old television set.

Definition

Noun: 1. Cathode Ray Tube: A specialized vacuum tube in which a heated cathode emits a stream of electrons. This electron beam is accelerated and focused by high-voltage anodes and directed (or deflected) to strike a phosphorescent screen, creating a visible image. This technology was the foundation for traditional television sets, computer monitors, and oscilloscopes.

Usage Examples

• Noun:
  • The old computer monitor used a bulky CRT, making it very deep and heavy.
  • Before flat-screen LCDs became common, most televisions contained a CRT.
  • The engineer adjusted the CRT in the oscilloscope to get a clearer signal reading.

Advanced Usage

• "CRT display/monitor/screen": A complete display device built around a cathode ray tube.
  • The classic arcade game had an authentic feel due to its vibrant CRT monitor.

• Flat-panel display (n): A modern display technology (e.g., LCD, LED, plasma) that is thinner and lighter than a CRT, often mentioned in contrast.

Synonyms

• Picture tube (specifically for televisions)
• Display tube
• Braun tube (historical/technical term)

Related Terms (Technical Context)

• Phosphor (n): The coating on the inside of the screen that glows when struck by the electron beam.
• Electron gun (n): The assembly inside the CRT that produces and emits the electron beam.
• Deflection coils (n): Electromagnets that steer the electron beam across the screen.
