It’s an old display technology used in computer monitors and TVs. The image is formed by firing electrons toward a screen coated with phosphor, which glows when hit. Working Principle: An electron gun emits a beam of electrons. These beams move at high speed and hit the fluorescent screen, creating bright spots. The beam passes through two pairs of deflection plates: One pair moves the beam up and down (vertical). The other moves it side to side (horizontal). Together, they control the position of the beam anywhere on the screen. The tube is sealed in a vacuum glass so electrons can travel freely. Main Parts of CRT: 1. Electron Gun Assembly: Generates and focuses electron beams using parts like cathode, grid, and anodes. 2. Deflection Plates: Control the direction of the beam (electrostatic or electromagnetic). 3. Fluorescent Screen: Inner surface coated with phosphor that glows when struck by electrons. 4. Aquadag Coating: A graphite layer that collects secondary electrons and keeps the screen electrically balanced. 5. Glass Envelope & Base: Encloses all components in a vacuum. Light Emission: When the electron beam hits the phosphor, it produces fluorescence (instant glow) and phosphorescence (afterglow). This is what creates the visible image on the CRT screen. #ComputerGraphics #BanglaTutorial #Lecturelia #CSETutorial #ComputerGraphicsBangla #CRTDisplay #CathodeRayTube #DisplayDevices #ComputerScienceBangla #EngineeringStudents #GraphicsLecture #BanglaLearning
