Display Devices Display Display Devices Devices :- As we know that there there are Several Display Display Devices Devices those are used for displaying Results on Screen when Processing gets Completed: so for this Purpose we uses Monitors, Printers , Plotters , and Speakers for Displaying Results those are Processed after Processing. Among of them Monitors are Widely used for displaying Results. Monitors are based on Concept of Cathode Ray Tube. Generally there are two types of Monitors First Which are Similar to Televisions and Seconds are LCD or Liquid Crystal Display.
How Monitor Works :Every Monitor has a Electronic Gun which Creates or Emits a beam. A beam is also Called as Cathode Rays or Some signals. The Electronic Gun Always Fires Beam , after the Great Great Reflections Reflections this will conduct with with the Phosphor which which is Insulated at the Screen of Monitor . First When a Signal has Passes then Gun will Fires theses Sign Signal alss Then Then afte afterr Many Many Refl Reflec ecti tion onss with with this this Tube Tube this this will will Cond Conduc uctt to the the Phosphor Phosphor which which is Coated with the Screen Screen of Monitor . After the Conducti Conduction on this will Emits Some Light on your Screen. Electron Gun in a CRT is Composed of a heated Metal Cathode and also with a Control Grid. Every Signal must be Passed from the Gun’s inner coil or Wire which is also Called as Filament and When a Signal has generated then this is the Control Grid which Specifies how much Reflection Reflection will be there and Accelerating Voltage Level. The Amount of Light or area for Display depends upon the the Number of Strikes to the Phosphor System. There are two ways for Focusing either with Electronic Gun or With Magnetic Fields. Electronic Method is used in the Television and Monitors and For using the Magnetic Magnetic Fields Fields Some Special Special Lens are Focus Focus outside outside the Devices Devices and these are used for Small displays. There are two coils used by Electronic Beam those are Horizontal and Vertical in nature nature The One Pair Pair is Placed Placed opposit oppositee with Each other other and Second Second Coil Coil is Placed in Top and Bottom Places So Controlling the Deflection of Bean with Phosphor and For Controlling Controlling The Height and Width of Image. Image. The Actual Size Size of Image Will Refers to the Number of Spots of Light on Screen. The Maximum Number of points that can be displayed without overlapping are Known as Resolutions. The Resolution can also be Measured as the Total Number of Points per Centimeters those are both Horizontally and Vertically in nature. The Resolution Resolution of CRT CRT also depends upon 1) Type Type of of Phosp Phosphor hor 2) Intensity Intensity or Amount Amount to be Display Displayed ed by CRT 3) Focusing Focusing and Deflecti Deflection on of CRT CRT Gene Genera rall lly y Reso Resolu luti tion on in high high Qual Qualit ity y is 1280 1280 by 024 024 and and The The Reso Resolu luti tion on of Monitors also Depends upon the the Size or Length of the Monitor , Now 12 inchdes to 27 inches Monitors are Available.
