3.  Display systems are the focal point of any human-machine interface.  It is an Essential Component.  Applications  The role of electronic displays is becoming increasingly crucial consumer electronics, Information processing, Entertainment, Intelligent offices/homes. Introduction

4.  Conversion of electronic signals to specific location.  Adjust images to the color.  Direct view enable user to view screen directly.  By using Optical devices magnifies and displays on larger screen. TECHNIQUE BEHIND DISPLAY SYSTEMS

5. CLASSIFICATION OF DISPLAYING DEVICES Light emitting devices eg : CRT’S, electro luminescent (EL), vacuum fluorescents displays (VFD’S) Non Light emitting devices eg : liquid crystal displays (LCD’s) and electro chromic displays (ECD’s)

6. TYPES TOUCH SCREEN LASER IMAGING ORGANIC EL DISPLAY LCD’S VFD’S POLYSTER PANELS 3D DISPLAYS OPTICAL FIBERS

7. TOUCH SCREEN DISPLAYS

8.  Touch Screen is a input device  Shonkh Technologies developed information with LCD/CRT touch screens  Working it includes touch sensor (to receive), electronic controller (convert i/p to conv. Bus protocol )& software driver (to convert the bus information to cursor action), and system utilities.  Applications - ATMs, and casino gaming

9. LASER IMAGING

10.  A German company has developed laser imaging Technology  Laser beams travel over the screen  These provide clear, non-reversed images on the screens of any size  It is high speed photograpy  Laser can be formatted into a thin sheet of light

11.  This is emitting their own light also provide wide view angles  Quick response speed  Researchers in Japan with compounds having low molecular weights, developed element technologies necessary to create organic EL displays. They brought out an organic EL display for car radios  These use fluorescent organic compounds as Luminescent materials ORGANIC EL DISPLAY

12.  LCD Stands for Liquid Crystal Display  Manipulates existing light to produce an image where as CRT, plasma emit light.  Color Display  Advantages - widespread use of notebook computers  drawbacks LCD’s

14.  VFD stands for vacuum fluorescents displays  Invented in 1966  It is a chip  It is multi color display  Applications – telecom, medical, home appliances, vending machines, point of sale VFD’s

15.  Introduction - Researchers have developed thin- film transistor displays out of polyethylene terephthalate thin, flexible and rugged plastic can be rolled up, folded, or bent it practically any shape desired Applications Applications notebooks,video-games,non-conventional displays. notebooks,video-games,non-conventional displays. POLYSTER PANALS

16. ADVANTAGES ► digital watches ► finger tops ► palmtops, laptops ► mobile phones ► digital cameras ► PC monitors, and TV’s

17. The display field is vast. Newer display technologies continue to evolve, in synchronism with modern-day convergence devices. The general awareness and knowledge about display systems are on a lower level. In order improve develop effective, efficient display systems.
