Dear Sir or Madam,
PolyIC will kick off the trade show season this spring by participating in the SID Display Week 2011 in Los Angeles.
In this issue of our newsletter you will learn all about our new PolyTC® product line that is suitable e.g. for touch screen applications. We present the advantages of the transparent conducting PolyTC® films and how they can be used in the design of operating elements. Possible applications of PolyTC® films include, among others, EMC (Electromagnetic Compatibility) screening and as electrodes.
PolyIC is a gold sponsor in the LOPE-C 2011 conference and exhibition! Come and see us in Frankfurt from 28 to 30 June.
Enjoy reading our newsletter!
Yours,
Wolfgang Mildner
Managing Director PolyIC |

| Preview: SID 2011 in Los Angeles - PolyIC as exhibitor - 15 to 20 May 2011 |
|
| PolyIC will participate as an exhibitor in the SID International Symposium, Seminar and Exhibition taking place from 15 to 20 May 2011 in Los Angeles (US). PolyIC's focus will be on showcasing the new PolyTC® product line, the transparent and conducting films suitable e.g. for touch sensor applications. Touch sensors are already widely used especially in mobile phones, and the market is expected to continue to grow strongly over the next years. This is where PolyIC's transparent conducting films (PolyTC®) offer an excellent basis for replacing the ITO films commonly used today. PolyTC® films are perfectly qualified to meet the requirements of the strongly emerging multi-touch sensor industry thanks to their customizable layouts which can be realized during production without complex additional steps. The PolyTC® technology can be applied to both resistive and capacitive touch sensors. |

Information: All advantages of transparent conductive films PolyTC® from PolyIC |
|
|
|
|
|
Compared to conventional ITO technology, PolyTC® transparent conductive films offer high transparency, flexibility, and cost-effectiveness.
The advantages of PolyTC® conductive plastics at a glance:
- High optical transparency over the entire visible wavelength range
- Individually customizable layout
- Individually adjustable electrical conductivity
- High availability as a result of mass production in a roll-to-roll process
- High flexibility on PET film
- Cost-effective alternative to structured ITO films
Liberate yourself from your dependence on indium – with conductive films from PolyIC.
Since the beginning of the year 2011, PolyIC offers an additional product line, called PolyTC®. This stands for transparent conductive films. The booming market for displays, touch screens, capacitive control elements, and EMC shielding is driving the development of efficient new ways to manufacture transparent conductive films. The indium tin oxide (ITO) coatings currently in use are reaching their limits due to a scarcity of resources as well as the expensive process involved. |

Applications: PolyTC® as touch screen |
|
|
|

Touch sensors are the basis of modern, interactive input devices which stand out due to their ease of operation. There are resistive and capacitive touch sensors which have distinctly different designs:
- Resistive touch sensors use the pressure an object exerts on an input medium to establish a connection between two transparent conducting layers. The exact XY position of a touch point on a surface can be calculated from this electrical contact using the voltage gradients applied on the films in X and Y direction.
- Capacitive touch sensors already recognize the proximity of electrically conducting objects, but they can be regulated so that they have to be touched in order to switch. Pressure is not required here as opposed to the resistive technology. The surface of capacitive touch sensors is charged electrically. When touched, a small charge transport is created. This minimum current flow is measurable on the surface where the even voltage field is established. Variations in its intensity compared to the areas not touched yield a specific touch point on the surface.
Resistive touch sensors have set the touch screen boom in motion; this process was additionally boosted by the multi-touch capability of the capacitive sensors, a trend that is still going strong. Smart phones, for instance, with multi-touch functionality are equipped with a capacitive sensor. |

Applications: PolyTC® as operating element |
|
|
|
|
|
| Touch keys are electronic switching devices actuated by finger touch which do not contain any mechanically moved parts. The switching operation is triggered, e.g. by a change in the capacitance caused by touching. PolyIC produces transparent conducting films under the brand name PolyTC®. You can use these films to realize flat touch keys as operating elements. The capacitive touch keys provide the following benefits: transparent, backlight capable, thin and flexible. These features can be used in all applications requiring easy-to-clean operating elements with modern design without additional mechanical components. Applications for operating elements include, for instance, the interior of vehicles, white goods (large electronic household appliances like stoves, refrigerators and freezer), brown goods (electrical or electronic consumer products such as TV sets, radio and hi-fi appliances) and for medical devices.

Market Information: PolyTC® with EMI as application |
|
|
|
|
|
The term EMC (electromagnetic compatibility) refers to electronic interference that can disturb an electronic device or that can even be produced by it. Since electronic circuits are becoming more complex all the time, e.g. in the automotive sector, disturbance caused by EMC are on the rise as well. This risk can be curbed by using components that fall under the category of EMC screening.
PolyTC® offers the following advantages in terms of EMC:
- customer-specific layouts, e.g. grids in rhombic, rectangular or hexagonal design
- individual adjustment of the surface resistivity and thus screening effect and desired transparence
- customer-specific geometry used to customize the cut-off frequency of the EMC film.

Applications: PolyTC® as electrode |
|
|
|
|
|
|
|
Electrodes are electrical conductors consisting mainly of metal which are used to conduct current. PolyTC® is a highly conducting film that is well suited as flexible electrode material. This film can be custom-printed with a conductive structure. It is even possible to print the conductors to such a fine degree that is invisible to the human eye enabling transparent electrode grids to be manufactured.
It is thus of particular interest for applications requiring "invisible" current transport. Unlike other transparent conductors such as e.g. ITO, the printed grid structures have a neutral color; color distortions do not occur. This opens up a multitude of application options for PolyTC® films including organic light-emitting diodes (OLED), organic solar cells (OPV), printed transistors or as heating electrodes for screens and mirrors. |
