Phosphorescence is the term used to characterize the light given off by a phosphor after it has been exposed to an electron beam.Overview of computer graphics, storage tube graphics display, Raster scan display. Phosphors glow when a high-energy electron beam hits them. Phosphorus-coated screen: The inside front surface of every CRT is coated with phosphors. The deflection yoke which is connected to the sweep generator creates a fluctuating electric or magnetic potential.ĥ. In a conventional CRT, the yoke is linked to a sweep or scan generator. It creates an electric or magnetic field which will bend the electron beam as it passes through the area. Deflection Yoke: It is used to control the direction of the electron beam. Multimedia computer information audio, video, image, animation, etc represent computer. Focusing system: It is used to create a clear picture by focusing the electrons into a narrow beam.Ĥ. Explain the basic hardware specification required for multimedia in hindi. Control Electrode: It is used to turn the electron beam on and off.ģ. The electron gun creates a source of electrons which are focused into a narrow beam directed at the face of the CRT.Ģ. Electron Gun: Electron gun consisting of a series of elements, primarily a heating filament (heater) and a cathode. The color you view on the screen is produced by a blend of red, blue and green light. What Is Computer Graphics In Easy Way : It is an art of drawing Circle, lines, rectangle, ellipse and other mathematical figure with computer with the help. Once the electron heats the phosphorus, they light up, and they are projected on a screen. Septemat 9:28 pm Hypetgraphics kya Hota he. This pdf is a good seluson is a computer graphics. The image on CRT display is created by firing electrons from the back of the tube of phosphorus located towards the front of the screen. Categories Multimedia in hindi Tags hypertext&hypermedia in hindi. CRT is a technology used in traditional computer monitors and televisions.
