Heraeus Shows 55 Inch Touch Screen From Inputek With Clevios Conductive Polymer Inside

(Nanowerk News) The application of Clevios™ PEDOT:PSS in touch technology - providing clear, conductive and flexible properties in touch devices - has resulted in the preparation of the first large area PCT touch screen pilot-product by Inputek, Taiwan.
The specialist IC design house and PCT touch solutions company Inputek has incorporated Clevios™ into the device using screen printing and etch patterning processes. The preparation of the demonstrator with 10 sensor points provides a smart and exciting example of technical advancement at an economic price. Applications in signage, point of sales, industrial and digital white boards are currently being investigated.

The Clevios™ PEDOT:PSS range from the Display & Semiconductor Business Unit of Heraeus consists of materials for antistatic through to highly conductive applications. Materials are modified for their application method, usually printing or coating, and for their end application requirements. Typically Clevios™ coatings can reach 100 -250 Ohm/sq. at a transparency of 90% (excluding substrate film). Clevios™ is increasingly finding applications in touch screens and sensors, as well as OLEDs, organic solar cells and security coatings. The 55 inch touch screen uses a Clevios™ that provides 150Ohm/Sq.
Dr Stephan Kirchmeyer, Head of the Display & Semiconductor Business Unit at Heraeus, said “The work with Inputek is an enabling technology, generating exciting new business opportunities and options for the touch display industry. Using conductive polymer coating and patterning options, large touch devices are more economic, of higher optical quality and can even be curved or flexible.”
Mr Andrew Chung, General Manager at Inputek, added. “The inclusion of patternable conductive polymers into large area PCT screens drives down costs and so increases the opportunities in many consumer interface applications. Soon restaurants will have touch tables as menu ordering, payment and even gaming options.“
