Plastic Touch Panels (polycarbonate/rugged)

Tough touch panels use polycarbonate and chemically-strengthened glass to assure durability, yet are lightweight, compact, and energy-efficient.

Lightweight yet durable plastic construction

Answering the demand for lightweight, plastic materials suitable for use in PDAs, Gunze combines a Film-Film (F-F) touch panel with a plastic substrate. The substrate comprises transparent electrodes on a plastic film 0.1 - 0.2 mm thick. The film is adhered to a 1 - 2 mm thick plastic board.

Polycarbonate touch panels

Gunze adjusts the heat expansion coefficients of the polycarbonate material used in its touch panels, overcoming warping problems that can result when plastic is used instead of glass.

In addition to being lightweight and fracture resistant, polycarbonate can be shaped in any way imaginable, enabling design possibilities other than traditional rectangles or squares.

Chemically-strengthened glass touch panels

Gunze creates rugged touch panels by substituting the standard glass in Film-Glass panels with chemically-strengthened glass. Chemically-strengthened glass is twice as durable and impact resistant than standard glass.
