  PolyTouch Technology
 

As the demand for advanced user interface continues to evolve, EDT is proud to present the newest innovation in capacitive touch technologies.  Introducing EDT PolyTouch™, capacitive touch solution, an alternative to touch sensory design that is both easy to implement and highly reliable. Unlike traditional resistive touch panels, EDT PolyTouch™ technology utilizes unique structural design that omits the need for sensory film, allowing a much more durable composition and wider operating environments.  Additionally, through the use of special coating process, each EDT PolyTouch™ design can be decorated directly without the need of extra cover lens overlay, so that performance for both optical and functional properties will remain superb and accurate.
 

Elegant, yet convenient, EDT PolyTouch™ series is an excellent touch solution complementary to visual medium for any design.  Equipped with various pre-installed functions and commands, each PolyTouch™ panel can be easily integrated and made compatible with either existing or newly developed system for fast implementation and development.  Standard EDT design offers single touch and multi touch alternatives.  Both maybe standardized or customized and be integrated as part of the LCM design.  Compatible among TFT, Mono and CSTN, EDT’s PolyTouch™ series is the perfect solution for excellent visual display and user interaction requirements.

  • PolyTouch-1D
  • PolyTouch-2D
As suggested by name, using single touch design, capacitive touch panel can be used to emulate typical user interface such as tapping, sliding or zooming. When contact is made onto touch panel surface, a disturbance on the electric field is thus created.  The signal is then transferred to sensory IC through touch sensors.  By measuring the change of capacitance between touch panel surface and user, this variance can then be interpreted as a form of trigger for recognition.
1D (Single Touch) Applications

Similar to single touch technology, multi-touch capacitive touch panel utilizes the disturbance of capacitance between touch panel surface and user contact to trigger signal activation.

Unlike single touch design, however, multi-touch panel further expands this concept with increase functionality, so that different gestures can be used to issue more complex commands, such as sliding, zooming, rotating, etc.  With increase of sensitivity, hand-writing function can also be utilized as part of the user input alternatives.

2D (Multi-Touch) Applications

  

Aside to strengthen touch panel scratch resistance and to provide additional protection, cover lens also allow designers to incorporate various graphics and decorations to highlight user interface.  Based on application requirements, EDT will able to assist clients to customize the most suitable design and functionality as they desire.

Material: Glass (7H)/ PMMA (4~5H)/ PET (2~3H)
