Presentation Transcript

  1. 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 (-20°C...+70°C) • 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 2

  2. 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.

  3. Y5 Y4 Y3 Y2 Y1 Y0 X0 X1 X2 X3 X4 X5 X6 X7 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.

  7. provided by: Data Modul customer Integration: I²C (Chip-Integration on custom-board)MOQ: 5k pcs configuration-tool customer application • No operating system necessary • Interface: I²C only • Touch-Function: real Multi-Touch-Function • Customer has to take care of the chip integration by himself. Data Modul will provide an application note. • Customer has to sign a NDA to get a protocolNDA_easyTouch:S:\Displaytechnik\Touch_Easy\Specifications\Controller\Atmel-Controller (single Chip) „operation system“ Atmel-Chip or „stamp“ I²C Touch-Panel driver X,Y coordinates settings Custom board CPU

  8. Integration: Windows 7 with DigitizerMOQ: 5k pcs provided by: Data Modul customer customer application Operationsystem MS Touch-Kit Mouse USB (Windows 7) Touch-Panel easyTouch controller or„stamp + stamp master“ • Touch-Function: 2 Finger Mouse Function, , Multi-Touch via MS-Touch-Kit • Windows 7 only • Data Modul provides a configuration-tool to adjust the settings during the development phase • For the MP, the touch controller could be preinstalled (e.g. sensibility) according to the requirements of the customer.

  15. 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 ->driver) 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 16

  16. 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
