SUNNYVALE, Calif. — Fujitsu Components America Inc. has announced the release of self-wetting adhesive protector sheets that reduce surface damage to touchscreens and flat-panel displays in use or during shipping, while preserving the optical quality and extending the life of the touch device. Because they are repositionable, the protector sheets reduce waste and materials costs.
The RoHS-compliant protector sheets feature a 3H surface hardness that is scratch- and chemical-resistant, yet offers excellent stylus registration for touch applications. The sheets are suitable for high-use, rugged and harsh applications, such as POS terminals, self-service kiosks, manufacturing and warehouse equipment and mobile field sales and service devices. They also offer protection for product shipping and testing.
The patented, self-wetting adhesive virtually self-applies by spontaneously wetting out on smooth surfaces with no or very low finger pressure to adhere to a display or touchscreen, yet it provides high shear resistance to prevent sheet displacement. The sheet can be repositioned during installation as necessary without affecting performance. The end user can remove the sheet by hand, even after an extended time, without leaving any residue or creating static electricity. Application of a new sheet can then be accomplished, also without generating static electricity, thus avoiding the attraction of undesirable dust particles.
The protector sheets are available in anti-glare (matte) and clear hardcoat, and an anti-reflective coated version of the clear option also is available. They are a maximum of 0.007 inches thick, depending on the type, and have an operating temperature range of -22 to 158 degrees Fahrenheit (-30 to +70 degrees Celsius). The typical optical properties of a clear protector sheet are 91 percent transmissivity with one percent haze, and the anti-glare protectors are 90 percent transmissivity with eight percent haze.
The protector sheets are custom die-cut to fit the specified display's surface dimensions and come in a variety of packaging options. Pricing varies by protector sheet size, packaging and quantity, starting at less than $1.
