Touch Screen Technology

  1. 1.  Introduction History Components Technologies Pros & cons Applications Conclusion
  2. 2.  A touch screen is anelectronic visual displaythat can detect thepresence and location of atouch within the displayarea. Touch screen can alsosense other passive objectssuch as stylus.
  3. 3.  The first touch screenwas a capacitivetouch screendeveloped by E.A.Johnson at the RoyalRadar Establishment,Malvern, UK in 1965.
  4. 4.  A basic touch screenhas three maincomponents : Touch sensor Controller Software driver
  5. 5.  A touch screen sensor is aclear glass panel with atouch response area. The touch sensor is placedover a display screen sothat the responsive areaof the panel covers theviewable area of thescreen.
  6. 6.  The controller connect between the touch sensor andthe PC. Take information from the touch sensor and translateit into information that PC can understand.
  7. 7.  The driver allow the touch screen and computer towork together This makes touching the screen as same as clickingthe your mouse at the same location on the screen.
  8. 8.  Composed of severallayers Two Electricallyconductive layersseparated by anarrow gap. Resistive touch isused in restaurants,factories andhospitals due to itshigh resistance toliquids andcontaminants.
  9. 9.  uses ultrasonic wavesthat passes over thetouch screen panel. This change in theultrasonic wavesregisters the position ofthe touch event andsends this informationto the controller forprocessing.
  10. 10.  Consist of an insulatorsuch as glass , coatedwith transparentconductor such as ITO(Indium Tin Oxide)  touching the surface ofthe screen results in adistortion of thescreenselectrostatic field,measurable as a changein capacitance. one requires a specialcapacitive stylus
  11. 11.  An infrared touch screenuses an array of X-Yinfrared LED and photodetector pairs around theedges of the screen todetect a disruption in thepattern of LED beams. These LED beams crosseach other in vertical andhorizontal patterns. Thishelps the sensors pick upthe exact location of thetouch.
  12. 12.  In this two or moreimage sensors areplaced around theedges of the screen.A touch shows up asa shadow and eachpair of cameras canthen be pinpointed tolocate the touch.
  13. 13.  User friendly Fast response Error free input Use finger , fingernail , glovedhands , stylus or any soft tippointer Easy to clean Does not interfere mouse andkeyboard Make computing easy , powerfuland fun It benefits children
  14. 14.  Finger stress Fingerprints screen has to be really big not to missthings when pressing them with your finger big screen leads to low battery life touch screen means screen can’t be read too well indirect sunlight as it applies an additional not 100%transparent Fatigue
  15. 15.  ATMS DUAL TOUCH SCREENLAPTOPS. SMART PHONES,IPAD GROCERY STORES. MUSEUMS. CORPORATEINFORMATION ETC.
  16. 16.  Designers are trying to use touch screen to simplifyinput commands Today , touch screen has becomes adopted bycomputers users of all abilities because it is simple,fast and innovative. In future there is no usage of mouse and keyboardsas they will be replaced by touch screen.
