Resistive Touch Screen User Interfaces

NKK Switches'resistive touch screens allow for choice of user input via finger, glovedfinger or stylus. This is in contrast to capacitive touch screens where theonly reliable input is via a non-gloved finger. Resistive sensing is thetechnology of choice for critical applications.

FTSeries touch screens provide engineers with the flexibility to handle manyapplications. Customization options include screen size, film choice, glassthickness, material combination, tail type and location, number of keys (ondigital models) and integration of monitors and touch screens together.

Five wire models are useful for larger screens used onlarger equipment. For portable applications and mobile devices, NKK has taken the long screen life of5-Wire technology and the lower power consumption of 4-Wire technology andcombined it into its latest enhanced 4-Wire designs.

All models in the FT Series aretoughened with films and coatings to avoid scratching and environmentaldeterioration. Film surface comes standard with non-glare and hard coatedtreatment for ease of use and maintenance of surface integrity. An optionalfilm which eliminates fingerprints is also available.

Visual artifacts are eliminated via anti-Newton ring film.Screens are also resistant to static electricity and noise pollution. Theyfeature high touch point density, translating to more precision, the reductionof false actuations and quicker response times. Temperature fluctuations do notaffect the drift-free operation.

NKK'sdigital FT Series touch screen is designed to replace a pushbutton panel orkeypad when more complex tasks such as drawing are not required.

Touch screen controller boards and drivers for these devicesare available from NKK for USB and RS232C communication requirements. NKK touch screensare compatible with Windows 7, Windows Vista, Windows XP and several legacyWindows operating systems.

IC chips are offered for the 5-Wire and 4-Wire touch screensfor engineers who prefer to design their own controller boards. These chipsprovide high speed and accuracy. Receptacle connectors can be orderedseparately.
