Key benefits

• usage with protective glass up to 1cm thickness
• multi-touch function
• usage with gloves (latex, leather, rubber)
• maximising the range of utilisation
• high transmission ratio of 90
• automatic calibration drift compensation
  (freely definable)
• extended temperature range (-20C...70C)
• excellent EMC and EMI behaviour
• high flexibility integrating the touch controller
• low power consumption (5V x 20mA) independent of
  the size of the touch panel

Function

• The touch sensor consists of a multilayer
  ITO-foil(indium tin oxide)
• Couples of electrodes generate an electrical
  field.
• When a finger touches the panel the field
  coupling will change. The controller will
  detected the change and calculate the position.

4
Definition of the touch-area

• X and Y-lines are defining the touch area
  (matrix-structure).
• The numbers of measuring points is defined by the
  numbers of X- and Y-lines. E.g. 8 x 6 48 or 18
  x12 216 (depending on the controller and the
  design of the foil).
• By interpolation a theoretical resolution of 1024
  x 1024 is possible (10bit).
• The sensitivity of the touch could be adjusted by
  software.

• Advantage of the stamp concept
• Atmel touch chip is an BGA (ball grid array with
  a pitch of 0,65mm -gt difficult to solderStamp is
  easy to solder on the PCB board of the customer
• Stamp is logistic wise easy to handle (no MOQ)
• Flexible integration of the stamp on customers PCB

General advice when setup easyTouch

• Fixation of the easyTouch sensor on a table with
  adhesive tape (Tesa)
• Install the driver software first, then connect
  the hardware(check for latest driver updates on
  our website (support -gtdriver)
• Please note that the touch-cable is connected
  correctly
• Pay attention that the power supply is grounded,
  the computer runs by a battery or LAN-cable is
  connected to the computer
• Noise suppression could be done by Data Modul if
  the customer provides the complete system

Usage of a front foil
When using a front foil the foil must always
laminated on the touch or a glass to avoid air
gaps and malfunction
