Construction

AMT offers customers a choice of construction types, 3-layer and 5-layer.

3-Layer Construction

3-Layer touch screens from AMT, the popular choice for most applications, comprise a film-on-glass construction, featuring a single circuit layer bonded to the scratch-resistant surface layer, over a layer of spacer adhesive, over a bottom layer of glass integrating the all-important conductive coating.
Despite the presence of necessary technologies, 3-layer touch screens are thin, versatile, and robust, an industry standard in normal environments.
We recommend 3-layer construction for all normal use touch screens of any size.

5-Layer Construction

AMT’s 5-layer construction, two ITO film on acrylic or polycarbonate, provides two layers of circuitry with the spacer adhesive sandwiched between, with the bottom layer optically bonded to the backing panel.
5-layer touch screens are considerably sturdier, and thus better suited to applications that sustain rigorous daily use.
AMT manufactures 5-layer types only as OEM special orders, based on individual customer needs and environmental requirements.
